    A rthur and Linda Lamprecht, appellants,
    v. Brent Schluntz and Gerald
    Schluntz, appellees.
    ___ N.W.2d ___
    Filed October 20, 2015.   No. A-14-995.
    1.	 Summary Judgment: Appeal and Error. An appellate court will affirm
    a lower court’s grant of summary judgment if the pleadings and admis-
    sible evidence offered at the hearing show that there is no genuine issue
    as to any material facts or the ultimate inferences that may be drawn
    from those facts and that the moving party is entitled to judgment as a
    matter of law.
    2.	 ____: ____. In reviewing a summary judgment, the court views the
    evidence in the light most favorable to the party against whom the
    judgment was granted and gives that party the benefit of all reasonable
    inferences deducible from the evidence.
    3.	 Rules of Evidence. In proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by the Nebraska
    Evidence Rules; judicial discretion is involved only when the rules make
    discretion a factor in determining admissibility.
    4.	 Rules of Evidence: Appeal and Error. When the Nebraska Evidence
    Rules commit the evidentiary question at issue to the discretion of the
    trial court, an appellate court reviews the admissibility of evidence for
    an abuse of discretion.
    5.	 Negligence: Presumptions. The doctrine of res ipsa loquitur is an
    exception to the general rule that negligence cannot be presumed. Res
    ipsa loquitur is a procedural tool that, if applicable, allows an inference
    of a defendant’s negligence to be submitted to the fact finder, where it
    may be accepted or rejected.
    6.	 Negligence: Proof. The essence of res ipsa loquitur is that the facts
    speak for themselves and lead to a proper inference of negligence by the
    fact finder without further proof.
    7.	 ____: ____. There are three elements that must be met for res ipsa
    loquitur to apply: (1) The occurrence must be one which would not, in

    the ordinary course of things, happen in the absence of negligence; (2)
    the instrumentality which produces the occurrence must be under the
    exclusive control and management of the alleged wrongdoer; and (3)
    there must be an absence of explanation by the alleged wrongdoer.
    8.	 Negligence: Evidence. When deciding whether res ipsa loquitur applies,
    a court must determine whether evidence exists from which reasonable
    persons can say that it is more likely than not that the three elements of
    res ipsa loquitur have been met. If such evidence is presented, then there
    exists an inference of negligence which presents a question of material
    fact, and summary judgment is improper.
    9.	 Negligence: Proof. The court should not weigh the evidence to deter-
    mine whether res ipsa loquitur applies. Instead, the court must determine
    whether there is sufficient evidence from which reasonable persons
    could find that it is more likely than not that the three elements of res
    ipsa loquitur have been proved and that it is therefore more likely than
    not that there was negligence associated with the event.
    10.	 Negligence: Presumptions: Proof. As a general rule, the mere occur-
    rence of a fire, with resultant damage, does not raise a presumption of
    negligence, although the circumstances under which a fire occurs may
    sometimes be such as to justify the application of the doctrine res ipsa
    loquitur and impose upon the defendant the burden of proving his free-
    dom from fault.
    11.	 Negligence. Res ipsa loquitur does not apply where the occurrence
    alone, without more, rests on conjecture, or where the accident was
    just as reasonably attributable to other causes as to the negligence of
    the defendant.
    12.	 Negligence: Presumptions. Liability cannot result from an inference
    upon an inference or from a presumption upon a presumption; an infer-
    ence of negligence could arise only from an established foundation fact
    and not from a further inference.
    13.	 Negligence. The doctrine of res ipsa loquitur is of limited and restricted
    scope and should ordinarily be applied sparingly.
    14.	 Appeal and Error. An appellate court is not obligated to engage in an
    analysis which is not needed to adjudicate the controversy before it.
    15.	 Affidavits. Under the terms of Neb. Rev. Stat. § 25-1334 (Reissue
    2008), affidavits offered for the truth of a particular fact (1) shall be
    made on personal knowledge, (2) shall set forth such facts as would be
    admissible into evidence, and (3) shall show affirmatively that the affi-
    ant is competent to testify to the matters stated therein.
    16.	 Trial: Witnesses. The opinion of a lay witness, formed without personal
    knowledge, would be inadmissible at trial and, therefore, would not sat-
    isfy the requirements of Neb. Rev. Stat. § 25-1334 (Reissue 2008).

    Appeal from the District Court for Furnas County: David
    Urbom, Judge. Affirmed.

    Bishop, Judge.
    Arthur Lamprecht and his wife, Linda Lamprecht, brought
    this action against Brent Schluntz and his brother, Gerald
    Schluntz, seeking compensation for property damage that the
    Lamprechts sustained from a fire that originated on Brent’s
    farm during a wheat harvest. The Lamprechts’ sole theory of
    recovery was premised on the doctrine of res ipsa loquitur. The
    district court for Furnas County granted summary judgment
    in favor of the Schluntzes, and the Lamprechts now appeal.
    We affirm.
    BACKGROUND
    On a hot and windy day in June 2012, Brent, Gerald, and
    their employee, Christopher Joppa, were harvesting wheat on
    Brent’s real property in Furnas County. As part of the harvest-
    ing operation, Joppa was operating a Case 9260 tractor with a
    grain cart attached. Brent and Gerald were operating combines.
    Brent and Gerald jointly owned the wheat, tractor, and com-
    bines, and Gerald was the sole owner of the grain cart.
    According to Brent, he, Gerald, and Joppa were doing
    “back-landing” in the wheatfield; Brent was operating a com-
    bine and was heading west, Gerald was in a combine head-
    ing east, and Joppa was in the tractor with the attached grain
    cart heading to unload Gerald’s combine. Brent testified that
    “as soon as the grain cart pulled up,” he saw a “flash . . .
    underneath the tractor.” Brent testified that he “pulled out and
    tried to wave at those guys, because they couldn’t see it, to
    get out and try to stomp it out or get out of there, but it just
    exploded.” Brent called the fire department immediately, and

    he, Gerald, and Joppa drove their respective pieces of farm
    equipment to the road. Brent testified the fire spread “like
    gasoline” although they attempted to “disk” the fields to cre-
    ate firebreaks to stop the fire. Several firefighters and other
    personnel responded to the fire around 3:30 p.m. Joe Kresser,
    the Stamford, Nebraska, fire chief, testified that when he
    arrived on the scene, the fire was in the wheatfield east of
    Brent’s house.
    Brent’s property was located approximately 2 miles south
    and half a mile west of the Lamprechts’ farm in Oxford,
    Nebraska, where Arthur raised corn, wheat, beans, and cattle.
    On the day of the fire, Arthur and his son were harvesting
    on Arthur’s property and had gone to Holdrege, Nebraska,
    to pick up Arthur’s truck from the repair shop. When they
    returned to Arthur’s farm around 4:30 p.m., Arthur saw
    smoke coming in their direction from the south. When Arthur
    got to where the fire was located, his wheat stubble was on
    fire and it had burned through a couple neighboring fields.
    Arthur attempted to shred his crops to make a firebreak or
    “disk out the fire.” Arthur testified that the fire came so
    fast he “couldn’t get in front of it” and that it went into his
    pasture. Arthur continued to disk lengthwise to the fire so
    it would not burn sideways, and one of his neighbors also
    helped disk with his tractor. Arthur testified that there were
    “lots of people there from the fire departments and the neigh-
    bors” trying to put the fire out.
    Kresser testified that when he first arrived at Brent’s prop-
    erty to put out the fire, he spoke to Brent to get his opinion
    about what caused the fire. Kresser testified that a field fire
    can sometimes start when a “bearing” “go[es] out or get[s] hot
    or something of that sort, and somebody can drive in a field,
    an exhaust pipe can start it.” Kresser recalled that Brent at that
    time thought the fire was caused by an electrical short on the
    tractor. Kresser did not examine the tractor because by the time
    the fire was under control enough to where he felt comfortable
    leaving the scene, the tractor was no longer in the field and
    Brent “wasn’t around.”

    23 Neb. Ct. App. 335
    Kresser authored a fire log the day after the fire. According
    to the fire log, the fire burned approximately 1,200 acres and
    was driven by high winds from the south and temperatures in
    excess of 100 degrees Fahrenheit. The fire log notes that the
    property owner, Brent, suspected the cause of the fire was an
    electrical short on the tractor pulling the grain cart and that
    upon inspection there was a “burnt wire” on the tractor.
    According to Brent, he asked Joppa what started the fire,
    but “[h]e didn’t know, either.” Brent told Joppa he saw “[the
    fire] come down from underneath the tractor.” Brent recalled
    that he told Kresser that he saw a “burnt wire” underneath the
    tractor, but he did not know “if it was from the fire coming up
    on it.” None of the farm equipment, including the tractor, were
    “burn[ed] up” in the fire.
    Brent testified that when he called his insurance company,
    “they found an expert to come out to examine the tractor,” but
    Brent did not recall who the expert was and did not testify as
    to what the expert’s conclusion was. When Brent was asked if
    he agreed that wheatfields do not typically spontaneously com-
    bust, he agreed that “[u]sually something starts everything.”
    Brent had never personally seen a wheatfield spontaneously
    combust and did not know anyone who had seen a wheatfield
    spontaneously combust.
    Joppa testified that all he remembers about the start of
    the fire was that he was getting ready to unload Brent’s or
    Gerald’s combine, when he saw one of them waving and
    signaling him to get out. Joppa looked in the mirror above
    the steering wheel of the tractor and saw flames, and he then
    “took off out of the field.” Joppa did not see the fire start
    and did not know for sure what started the fire, but “we were
    looking at the tractor.” Joppa recalled that the Schluntzes’
    mechanic told him that “the insurance adjuster was coming
    down to look at the equipment . . . that I was using” and that
    “they were looking at . . . the differentials. Something to do
    with the differentials.” Joppa explained that, in a four-wheel-
    drive tractor (like the type he was driving), a differential
    - 340 -

    switch box “locks your differential so you can pull — all four
    tires can pull at the same time.”
    Joppa testified that he grew up in North Dakota on a farm
    and that during his life, he had seen two wildfires start during
    harvest; Joppa testified that one of those fires was started by
    a bearing that “went out in the combine” and “[o]verheated
    and started the fire.” Joppa agreed that fires in wheatfields
    are not normal occurrences, although “they do have spon-
    taneous combustions” caused by too much heat. However,
    Joppa then testified, “I know that didn’t happen that day,”
    followed by his statement that “it could have happened that
    day, I guess. I mean, I don’t think it would have. I know it
    was really hot.”
    Although Joppa is not a mechanic and has no training as
    a mechanic, he has experience changing oil and filters, and
    greasing farm equipment, and he testified that he had previ-
    ously changed the oil and greased the tractor at issue. Joppa
    testified that their farm equipment is “serviced every morn-
    ing.” Joppa stated that he had no reason to believe that the
    tractor he was driving was dangerous or unsafe on the day
    of the fire and that he had no reason to believe there was a
    mechanical defect in the tractor he was driving.
    Arthur did not know what started the fire, other than what he
    read in the fire log authored by Kresser.
    The Lamprechts filed a complaint against Brent on May 30,
    2013. The Lamprechts initially alleged two theories of recov-
    ery: negligence for failure to properly maintain and repair the
    farming machinery and res ipsa loquitur.
    Brent filed a motion for summary judgment on January
    31, 2014.
    On March 10, 2014, the Lamprechts filed a motion for
    leave to file an amended complaint, which leave the court
    granted on March 20. The Lamprechts filed an amended com-
    plaint on March 31, containing the same allegations as the first
    complaint, but adding Gerald as a defendant.
    The Lamprechts filed a motion for leave to file a second
    amended complaint on September 25, 2014, which leave the

    court granted on October 27. The Lamprechts filed a second
    amended complaint the same day, alleging that “[t]his action
    arises out of the negligent maintenance and/or operation of
    farm equipment that started a fire which damaged the property
    of [the Lamprechts]. The matter is being prosecuted on the
    theory of res ipsa loquitur.”
    A summary judgment hearing was held on September 29,
    2014. Depositions of Brent, Arthur, Kresser, and Joppa were
    received into evidence. The Lamprechts offered an affidavit
    from Arthur into evidence, in which he stated that he had
    been farming in Nebraska for over 50 years and that he has
    operated and maintained tractors and other equipment used
    to harvest wheat. Arthur averred that in his experience, farm
    equipment will not start a fire unless it is negligently main-
    tained and/or operated. Arthur further averred that tractors
    and combines are universally used to harvest wheat, and
    fires and explosions caused by that equipment does not in
    the ordinary course of things happen unless there was negli-
    gence by the owners and/or operators of that equipment. The
    Schluntzes objected to Arthur’s affidavit on the bases that
    “[Arthur] is a farmer as alleged in his affidavit, but [Neb.
    Rev. Stat. §] 27-701 [(Reissue 2008)] require[s] experts to
    render opinions like [Arthur] is trying to do in this case”; that
    Arthur’s affidavit “offer[ed] a legal opinion with regards to
    whether there was negligence”; that Arthur did not base his
    opinion on firsthand observation or knowledge; that there
    was insufficient foundation, method, or basis for how Arthur
    arrived at his conclusion; and that Arthur’s opinion “even
    contradicts his own expert, . . . Kresser,” and also contra-
    dicted Joppa’s testimony. The court reserved ruling on the
    receipt of Arthur’s affidavit.
    On October 28, 2014, the court entered an order on the
    summary judgment motion. The court stated that “[t]he
    [Schluntzes’] objection to the receipt of [Arthur’s affidavit] is
    sustained and [Arthur’s affidavit] is not received.” The court’s
    order then made various factual findings, including the fol-
    lowing: The tractor ignited the fire, the Schluntzes “properly

    maintained and kept their equipment in good repair,” and
    “[t]he equipment was serviced every morning before harvest-
    ing started.”
    The court concluded that the instant case resembled the
    case of Security Ins. Co. v. Omaha Coca-Cola Bottling Co.,
    
    157 Neb. 923
    , 
    62 N.W.2d 127
    (1954), wherein the Nebraska
    Supreme Court concluded res ipsa loquitur did not apply
    where a building was damaged by smoke from a fire in a
    lunchroom that housed a Coca-Cola vending machine. The
    district court in the instant case concluded that based upon
    the evidence received, there was “not sufficient evidence from
    which reasonable persons could find it more likely than not
    that there was negligence on the part of the [Schluntzes].”
    The court found that no genuine issue of material fact existed
    and that the Schluntzes were entitled to judgment as a mat-
    ter of law. Summary judgment was granted in favor of the
    Schluntzes; the district court dismissed the Lamprechts’ second
    amended complaint.
    The Lamprechts now appeal.
    ASSIGNMENTS OF ERROR
    The Lamprechts assign as error, summarized and restated,
    that the district court erred (1) in granting summary judgment
    based on its conclusion that res ipsa loquitur did not apply,
    (2) in making certain findings of fact, and (3) in excluding
    Arthur’s affidavit.
    STANDARD OF REVIEW
    [1,2] An appellate court will affirm a lower court’s grant of
    summary judgment if the pleadings and admissible evidence
    offered at the hearing show that there is no genuine issue as
    to any material facts or the ultimate inferences that may be
    drawn from those facts and that the moving party is entitled
    to judgment as a matter of law. O’Brien v. Bellevue Public
    Schools, 
    289 Neb. 637
    , 
    856 N.W.2d 731
    (2014). In reviewing
    a summary judgment, the court views the evidence in the light
    most favorable to the party against whom the judgment was

    granted and gives that party the benefit of all reasonable infer-
    ences deducible from the evidence. 
    Id. [3,4] In
    proceedings where the Nebraska Evidence Rules
    apply, the admissibility of evidence is controlled by the
    Nebraska Evidence Rules; judicial discretion is involved only
    when the rules make discretion a factor in determining admis-
    sibility. Griffith v. Drew’s LLC, 
    290 Neb. 508
    , 
    860 N.W.2d 749
    (2015). When the Nebraska Evidence Rules commit the
    evidentiary question at issue to the discretion of the trial court,
    an appellate court reviews the admissibility of evidence for an
    abuse of discretion. Erickson v. U-Haul Internat., 
    278 Neb. 18
    ,
    
    767 N.W.2d 765
    (2009).
    ANALYSIS
    [5,6] The Lamprechts initially alleged two theories of
    recovery: (1) negligence for failure to properly maintain and
    repair the farming machinery and (2) res ipsa loquitur. The
    Lamprechts subsequently abandoned their negligence theory
    and amended their complaint to proceed solely on the theory of
    res ipsa loquitur. The doctrine of res ipsa loquitur is an excep-
    tion to the general rule that negligence cannot be presumed.

    281 Neb. 725
    , 
    798 N.W.2d 386
    (2011). Res ipsa loquitur is a procedural tool that,
    if applicable, allows an inference of a defendant’s negligence
    to be submitted to the fact finder, where it may be accepted or
    rejected. 
    Id. The essence
    of res ipsa loquitur is that the facts
    speak for themselves and lead to a proper inference of neg-
    ligence by the fact finder without further proof. Swierczek v.

    [7] There are three elements that must be met for res ipsa
    loquitur to apply: (1) The occurrence must be one which would
    not, in the ordinary course of things, happen in the absence of
    negligence; (2) the instrumentality which produces the occur-
    rence must be under the exclusive control and management
    of the alleged wrongdoer; and (3) there must be an absence
    of explanation by the alleged wrongdoer. McLaughlin Freight

    [8,9] When deciding whether res ipsa loquitur applies, a
    court must determine whether evidence exists from which
    reasonable persons can say that it is more likely than not
    that the three elements of res ipsa loquitur have been met.
    
    Id. If such
    evidence is presented, then there exists an infer-
    ence of negligence which presents a question of material fact,
    and summary judgment is improper. 
    Id. The court
    should not
    weigh the evidence to determine whether res ipsa loquitur
    applies. 
    Id. Instead, the
    court must determine whether there is
    sufficient evidence from which reasonable persons could find
    that it is more likely than not that the three elements of res
    ipsa loquitur have been proved and that it is therefore more
    likely than not that there was negligence associated with the
    event. 
    Id. Our analysis
    turns on the first element of res ipsa loquitur,
    that the occurrence must be one which would not, in the ordi-
    nary course of things, happen in the absence of negligence.
    See McLaughlin Freight 
    Lines, supra
    . Our Supreme Court has
    stated that this element “‘is of course only another way of stat-
    ing an obvious principle of circumstantial evidence: that the
    event must be such that in the light of ordinary experience it
    gives rise to an inference that someone must have been negli-
    gent.’” Anderson v. Service Merchandise Co., 
    240 Neb. 873
    ,
    880, 
    485 N.W.2d 170
    , 175 (1992).
    [10] As a general rule, the mere occurrence of a fire, with
    resultant damage, does not raise a presumption of negligence,
    although the circumstances under which a fire occurs may
    sometimes be such as to justify the application of the doctrine
    res ipsa loquitur and impose upon the defendant the burden
    of proving his freedom from fault. See Security Ins. Co. v.
    Omaha Coca-Cola Bottling Co., 
    157 Neb. 923
    , 
    62 N.W.2d 127
    (1954). In Security Ins. Co., the Nebraska Supreme Court
    affirmed a directed verdict in favor of the defendant bottling
    company, concluding that res ipsa loquitur did not apply to
    the plaintiff-insurer’s claim that the bottling company had
    negligently permitted its vending machine to catch fire. At
    some point during a day when no one was in the building, a

    fire broke out in the lunchroom where the vending machine
    was located. The evening janitor found the building filled
    with smoke and damage, but did not see a fire, and noticed
    the vending machine and adjacent wooden pop cases had
    been completely burned, leaving only the metal shell of the
    machine. Nothing else in the lunchroom had caught fire. The
    court in Security Ins. Co. concluded that the doctrine of res
    ipsa loquitur was of limited and restricted scope and should
    ordinarily be applied sparingly, and the court considered the
    doctrine inapplicable to the case before it, finding no prece-
    dent wherein a party had even attempted to apply the doctrine
    to a like situation.
    Our research has revealed no Nebraska cases wherein the
    doctrine of res ipsa loquitur was utilized against a defendant
    in an action for damages resulting from a field fire allegedly
    caused by the defendant’s tractor or other farm equipment
    where the exact cause of the fire was unknown. Outside of
    Nebraska, however, res ipsa loquitur has been rejected under
    circumstances similar to those in the case before us.

    428 P.2d 706
    (1967),
    owners of a wheat crop which had been destroyed in a fire
    that was allegedly started by a truck which had been used by
    the defendants in harvesting the wheat were held not to be
    entitled to rely on the doctrine of res ipsa loquitur. Viewing
    the evidence in the light most favorable to the crop owners,
    the court in Hamilton found that the fire had broken out in the
    field either near or under the defendants’ truck and that there
    was a high stubble on the field which could have ignited on
    contact with a hot exhaust pipe. The plaintiffs, it concluded,
    had failed to produce any proof, beyond pure speculation, that
    the truck had started the fire or that there had been some negli-
    gence on the part of the defendants. Res ipsa loquitur, it ruled,
    did not apply where proof of the occurrence alone, without
    more, still rested on conjecture or where the accident was just
    as reasonably attributable to other causes as to the negligence
    of the defendant.

    Similarly, in Emigh v. Andrews, 
    164 Kan. 732
    , 
    191 P.2d 901
    (1948), the plaintiff owner and lessee of a wheatfield could
    not rely on res ipsa loquitur to state a cause of action against
    a truck owner, whose truck allegedly started a fire that burned
    the plaintiff’s wheat crop. In that case, a fire started in wheat
    stubble at a point where the truck had just passed over, and no
    other persons or vehicles had been near that point. The Emigh
    court held that, at best, the facts raised a presumption that the
    truck caused the fire, but a mere presumption could not sup-
    port a further inference that the truck had been defective or
    improperly operated. The court in Emigh further noted that
    courts were reluctant to draw an inference of negligence from
    the starting of fires because fires are frequent occurrences and,
    in many cases, result without negligence on the part of any-
    one. The court noted that the established rule was that liability
    cannot result from an inference upon an inference or from a
    presumption upon a presumption, and concluded that, in the
    case before it, the presumption that the truck caused the fire
    “cannot well be said to speak ‘for itself.’”

    In Anderton v. Downs, 
    459 S.W.2d 101
    (Mo. App. 1970),
    res ipsa loquitur was held not to apply to the plaintiff-farmer’s
    claim for damages to 35 acres of his wheat, damaged by a fire
    that had broken out along the path that the defendant’s truck
    had taken in the plaintiff’s wheatfield. Although there was
    evidence that the truck had caught fire on a previous occa-
    sion, and the farmer alleged that the truck owner had been
    negligent in failing to repair known defects in the truck’s
    electrical and exhaust systems, the court found that res ipsa
    loquitur was not applicable, in part, because the court found
    that the plaintiff-farmer had failed to establish the cause of
    the fire. The mere occurrence of a fire, the court stated, does
    not prove negligence or raise any presumption as to the cause
    of the fire.
    In National Union Fire Insurance Company v. Elliott, 
    298 P.2d 448
    (Okla. 1956), the court held that res ipsa loquitur
    did not apply to an action filed by the insurer of a wheat crop

    destroyed by fire that was allegedly caused by the defendant’s
    truck while harvesting wheat. The defendant had left one of
    his trucks in the field, and when he returned, he noticed that
    the wheat stubble around the truck was on fire and the truck
    was engulfed in flames. The insurer argued that there was suf-
    ficient evidence to bring res ipsa loquitur into play because the
    truck was 6 years old, and was likely to have wiring defects
    and other malfunctions, and because the truck was shortly
    ablaze after it had been parked on the field away from the
    roadway where the fire could not have been started by inter-
    vening agencies. The court disagreed and refused to apply res
    ipsa loquitur, concluding that an inference of negligence could
    arise only from an established foundation fact and not from
    a further inference; the mere occurrence of an accident under
    unexplained circumstances would not support the application
    of res ipsa loquitur.
    In Thurman v. Johnson, 
    330 S.W.2d 179
    (Mo. App. 1959),
    a barn was destroyed by fire that originated in the defendant’s
    truck, which the defendant had driven onto the property to pick
    up a delivery of the plaintiff-owner’s oats. The truck caught
    fire after getting stuck in a rut as the driver brought the truck
    into the barn. The owner sought to recover damages for the
    fire under the theory of res ipsa loquitur, which the court in
    Thurman rejected. The court stated that although the occur-
    rence was “certainly one that does not ordinarily happen,” such
    an occurrence was not usually caused by lack of due care by
    the owner-operator. 
    Id. at 182.
       [11] In reviewing the above cases, it is clear that unex-
    plained fires can occur during harvesting and farming opera-
    tions, on or around trucks or other equipment used in farming
    operations. However, as observed by those courts, the mere
    fact that the fire occurred in such a manner does not warrant an
    inference of negligence. Res ipsa loquitur does not apply where
    the occurrence alone, without more, rests on conjecture, or
    where the accident was just as reasonably attributable to other
    causes as to the negligence of the defendant. See Hamilton v.

    supra. Courts are reluctant to draw an inference of negligence
    from the starting of fires because fires are frequent occurrences
    and, in many cases, resulted without negligence on the part of
    anyone. See Emigh v. Andrews, 
    164 Kan. 732
    , 
    191 P.2d 901
    (1948). See, also, 
    Thurman, supra
    .
    We note that there are cases where res ipsa loquitur has
    been applied to vehicles alleged to have started a fire. In
    one case, for example, a truck backed into a barn filled with
    hay and allegedly caused a fire from its hot exhaust gas and
    sparks; the court found that fires do not ordinarily occur
    during the loading or unloading of bales of hay in a barn
    absent someone’s negligence. See Seeley v. Combs, 
    65 Cal. 2d
    127, 
    416 P.2d 810
    , 
    52 Cal. Rptr. 578
    (1966). In another
    case where a vehicle was alleged to have started a forest fire,
    Roddiscraft, Inc. v. Skelton Logging Co., 
    212 Cal. App. 2d 784
    , 
    28 Cal. Rptr. 277
    (1963), a logging tractor that had been
    used in proximity to the fire had not been equipped with a
    spark arrester and had been smoking excessively. The court
    concluded that this supported an inference of negligence
    because as a matter of common knowledge, forest fires do
    not occur, other than perhaps from lightning, unless someone
    has been negligent, and therefore the cause of this forest fire
    was more likely than not from the negligence of the logging
    tractor owner.
    [12,13] In Nebraska, as a general rule, the mere occurrence
    of a fire, with resultant damage, does not raise a presumption
    of negligence, unless the circumstances under which a fire
    occurs justify the application of res ipsa loquitur. See Security
    Ins. Co. v. Omaha Coca-Cola Bottling Co., 
    157 Neb. 923
    ,
    
    62 N.W.2d 127
    (1954). In the instant case, the only evidence
    presented with respect to the fire’s cause was that Brent saw a
    “flash” underneath the tractor and that he found a “burnt wire”
    under the tractor. Kresser testified that a field fire can start
    when a bearing goes out or gets hot or that an exhaust pipe
    can start a fire, and Brent thought the fire could have been
    caused by an electrical short on the tractor. However, none
    of those explanations are ones which are more likely than not

    explained by negligence; and the mere fact that a fire started
    under Brent’s tractor does not lead to an inference that there
    was negligence. Even though a fire in a wheatfield may not
    ordinarily happen, such an occurrence is not so unusual as to
    justify an inference of negligence based upon an alleged lack
    of due care by the owner and/or operator of a tractor or other
    equipment being used to harvest the wheat. As with the cases
    cited above, we too are reluctant to draw an inference of neg-
    ligence from the mere happening of the fire, because fires are
    frequent occurrences and, in many cases, result without negli-
    gence on the part of anyone. See Emigh v. Andrews, 
    164 Kan. 732
    , 
    191 P.2d 901
    (1948). Further, as in Emigh, even when
    the facts may raise a presumption that the vehicle caused the
    fire, that mere presumption cannot support a further inference
    that the vehicle was defective or improperly maintained or
    operated. See 
    id. (liability cannot
    result from inference upon
    inference or from presumption upon presumption). See, also,
    National Union Fire Insurance Company v. Elliott, 
    298 P.2d 448
    (Okla. 1956) (inference of negligence could arise only
    from established foundation fact and not from further infer-
    ence). Moreover, we bear in mind that the doctrine of res ipsa
    loquitur is of limited and restricted scope and should ordinar-
    ily be applied sparingly. Security Ins. 
    Co., supra
    . We con-
    clude that fires like the one at issue can occur in the ordinary
    course of things in the absence of negligence and that thus, the
    Lamprechts cannot and did not establish the first element of
    res ipsa loquitur.
    [14] Our conclusion above is not based upon any of the
    findings of fact that the Lamprechts argue were error by the
    district court. We therefore find it unnecessary to address the
    Lamprechts’ assignment of error related to the district court’s
    factual findings. An appellate court is not obligated to engage
    in an analysis which is not needed to adjudicate the controversy
    before it. Papillion Rural Fire Prot. Dist. v. City of Bellevue,
    
    274 Neb. 214
    , 
    739 N.W.2d 162
    (2007).
    Because the Lamprechts cannot establish the first element
    of res ipsa loquitur, we agree with the district court that the

    doctrine of res ipsa loquitur is inapplicable as a matter of law,
    and affirm summary judgment in favor of the Schluntzes.
    The Lamprechts also assign as error the district court’s
    exclusion of Arthur’s affidavit offered into evidence at the
    summary judgment hearing. In his affidavit, Arthur stated that
    he had been farming in Nebraska for over 50 years, that he
    has operated and maintained tractors and other farm equipment
    used to harvest wheat, and that in his experience, farm equip-
    ment will not start a fire unless it is negligently maintained
    and/or operated. Arthur further averred that tractors and com-
    bines are universally used to harvest wheat and that fires and
    explosions caused by such equipment do not in the ordinary
    course of things happen unless there was negligence by the
    equipment’s owners and/or operators.
    [15,16] Under the terms of Neb. Rev. Stat. § 25-1334
    (Reissue 2008), affidavits offered for the truth of a particular
    fact (1) shall be made on personal knowledge, (2) shall set forth
    such facts as would be admissible into evidence, and (3) shall
    show affirmatively that the affiant is competent to testify to the
    matters stated therein. Whalen v. U S West Communications,
    
    253 Neb. 334
    , 
    570 N.W.2d 531
    (1997). Statements in affidavits
    as to opinion, belief, or conclusions of law are of no effect.
    
    Id. Arthur’s testimony
    was that of a lay witness. The opinion
    of a lay witness, formed without personal knowledge, would
    be inadmissible at trial and, therefore, would not satisfy the
    requirements of § 25-1334. See Boyle v. Welsh, 
    256 Neb. 118
    ,
    
    589 N.W.2d 118
    (1999). Arthur’s statements in his affidavit
    were merely legal conclusions that fires do not start by farm
    equipment without negligence. Such statements were properly
    excluded by the district court.
    CONCLUSION
    For the foregoing reasons, we affirm the decision of the
    district court.
