Plaintiff, 13 years 5½ months of age at the time, sustained severe and permanently crippling injuries to his left index and middle fingers on April 26, 1952, while mowing the lawn at defendant’s farm home with a power lawn mower. Defendant appeals from an adverse judgment of $2,000. The cause having been tried by the court, sitting as a jury, we “review the case upon both the law and the evidence as in suits of an equitable nature”, with “due regard * * * to the opportunity of the trial court to judge of the credibility of the witnesses.” Section 510.310(4) ; Scott v. Kempland, Mo.,
Plaintiff, who lived with his mother on defendant’s farm, was employed at 50^ per hour to mow defendant’s lawn “nearly an acre” in size. The lawn was “bottom” land and had been “filled * * * a little” during the Spring of 1952. At the time of accident, there were “some depressions in it because of the fill”; and, although it looked level, it was “uneven” and had “low and high places in it.” Defendant’s mower, which plaintiff used, was a “rotary type” power mower with “a gasoline engine * * * on the top part of the mower * * * connected by a shaft to a rotary blade,” which revolved “at a tremendous rate of speed” parallel with and'close to the ground. A metal shield covered the rotary blade, but there was sufficient clearance in front to permit “the grass to stand up as it comes in contact with the rotary blade.” The gasoline tank on top of the motor was filled through a small opening near the front of the tank, which was closed with a screw cap. Although we find no definite evidence to sustain the charge in plaintiff’s amended petition that this screw cap “was defective”, defendant testified that “if you don’t tighten it down good, it will vibrate off.” The gasoline motor operated only the rotary blade. . “You have to push it (the mower), it is not self-propelled.” However, it , was alleged in plaintiff’s amended petition “that the' vibration * * * of the said engine caused the said mower to propel itself forward even though no personal force was applied to the said mower”; and, plaintiff adduced evidence that “they will creep forward on you” and that “they go forward an inch or two and on rough ground they will go further than that because of the tremendous speed of this rotary blade.” And, when defendant was asked on cross-examination, “have you noticed it (the mower) vibrating where you have got a depression and a little hilly ground, you have noticed it move forward * * * haven’t you ?”, he replied, “I have seen it do that, it will do that.”
Plaintiff testified that, on the date of accident, defendant “got the lawn mower out *4 and put the gas in it and started it up and * * * pushed it fifteen or twenty foot and set the gas and handed it to me and I started mowing his lawn”; that defendant showed him “how to stop the mower”; but, that defendant gave him no other instructions about handling the mower and told him nothing about the dangers incident to operation or about the inherent characteristics or tendencies of the machine. Defendant said that “I told him (plaintiff) to be careful with it and to not put his hands or feet underneath the mower, that the propellors would cut him,” but defendant frankly admitted that he had not told plaintiff about the tendency of the mower to “creep” forward with the motor running or “about this gas cap having a tendency to vibrate and come off.” After using the mower “about thirty, maybe forty-five minutes,” plaintiff refilled the gasoline tank and then replaced the screw cap on the tank. After mowing some fifteen or twenty minutes more, he saw the cap vibrating and stopped the mower on “uneven” ground. The gasoline cap fell in front of the mower “about two inches from it,” plaintiff “walked around to the right” and reached down with his left hand to pick up the cap, and the mower “moved forward into my hand.” Plaintiff insisted that, before attempting to pick up the cap, he had stopped the mower "dead still” (although he did no't “kill” the motor or change the speed of it), and that he did not put his hand under the mower at any time.
At the time of accident, plaintiff was finishing the eighth grade in school. His attending physician expressed the opinion that plaintiff was a “pretty bright boy”— “above average in mentality” for his age. Prior to the accident, plaintiff had done other work for defendant, “maybe between thirty and fifty hours,” described by defendant as “farm work and picking up sprouts and things on new ground.” When he was “about 10,” plaintiff had started to drive farm tractors; and, after driving “for a year or two,” he had begun “working with a tractor” and farm machinery, such as plows, discs, harrows, etc. Upon trial, plaintiff insisted that he had not operated a power lawn mower prior to the date of accident, although he readily admitted that he had cut weeds with a mowing blade on “a little garden tractor.” Defendant testified that he was “under the impression that James (plaintiff) told me that he operated a mower like that on the school yard”; and, in a» statement signed by plaintiff on April 28, 1952, two days after the accident and while he was still in the hospital, it appears that “I used this type of mower about one whole summer last year (1951)” — “I had used the same type mower before at school but this was the first time I had used this one.” In the same signed statement, plaintiff had said “Mr. White (defendant) had told me to be careful using the mower.” However, this signed statement does not show that, prior to the date of accident, plaintiff had operated any power lawn mower having the same inherent characteristics or tendencies as defendant’s mower, or that defendant did •more than warn plaintiff, in very general language, “to be careful using the mower.”
Defendant’s complaints on appeal are that his motions for a directed verdict at the close of plaintiff’s case and at the close of all of the evidence should have been sustained, and that plaintiff’s signed statement of April 28, 1952, was erroneously excluded from evidence. The alleged error in overruling defendant’s motion for a directed verdict at the close of plaintiff’s case was waived when defendant subsequently introduced evidence on the merits [Stephens v. Kansas City Gas Co.,
The pleaded negligence with which defendant is charged, and upon which plaintiff relies, is in “failing to inform and warn him (plaintiff) of the dangers in operating the said motor (and) failing to warn or instruct him as to the dangers inherent in the said mower * * * when he (defendant) knew or should have known that because of his (plaintiff’s) youth and inexpe *5 rience * * * he was not qualified to control or operate the said power mower * * * and knew that the plaintiff was not aware of the hazards incident to the operation of the said power mower.” And, the reported cases leave no room for doubt but that a master has the duty to warn a youthful and inexperienced servant of danger incident to work he is required to do or operation of a machine he is directed to use, where by reason of such youth and inexperience the servant is not aware of and does not appreciate the danger and risk 1 .
It may be that, as defendant contends, he should not have anticipated that plaintiff would have been injured at the exact time and place, or in the precise manner, that he was. But, while defendant “was not bound to anticipate a condition or an occurrence that a reasonably prudent person could not foresee or guard against, ‘the fact that the precise manner in which the injury occurred was not foreseeable would not be a defense, if from (his) failure to warn * * * the defendant might reasonably have anticipated that injury of some kind would result.’ ” Miller v. Brunson Const. Co., Mo.,
Defendant employed plaintiff, a youth 13 years 5½ months of age, to operate a power mower with a rotary blade revolving “at a tremendous rate of speed” — traveling “so fast that you can’t even see it if you are looking at the edge of it” — which obviously was capable of inflicting, and in this instance actually did inflict, severe personal injuries. That an operator might, through carelessness or inadvertence,- get..a hand or foot within range of the rotary blade was recognized by defendant himself, who ,said that he gave a general warning to plaintiff “to be careful with it and to not put- his hands or feet underneath the mower, that the propellors would cut him.” But, defendant imparted no information or warning about the inherent characteristics or tendencies of the mower, i. e., its tendency, particularly on rough ground, to “creep” forward with the motor running, and the tendency of the screw cap to “vibrate off” — operating characteristics of the mower which were known to defendant but, as plaintiff insists without contradiction in the record, were unknown to him, and which subsequently resulted in injury to plaintiff. Conceding that defendant might have had no reason to have anticipated that the screw cap on the gas tank would “vibrate off” on the occasion under consideration and thus conceding that defendant might have had no duty to have informed or warned plaintiff of this particular characteristic or ten- *6 dencyof the mower, nevertheless defendant might well have foreseen or anticipated that, in the course of mowing his lawn “nearly an acre” in size, which had been “filled * * * a little,” had “some depressions in it,” and was “uneven,” plaintiff might have found it necessary or advisable to stop the mower on rough ground, walk around in front of it, and remove from its path some object or objects other than the screw cap, for example sticks, limbs or rocks. So, the trier of fact reasonably might have found that defendant should have informed and warned plaintiff of the tendency of the mower, particularly on rough ground, to “creep” forward with the motor running.
Negligence, which has been defined as “the failure to exercise the degree of care required by the circumstances” [Pearson v. Kansas City,
For that matter, defendant’s primary contention upon appeal is that his motion for a directed verdict, should have been sustained
not
because defendant was wholly free from negligence
but rather
because “plaintiff was guilty of negligence as a matter of law.” The adjudicated cases demonstrate that, under certain circumstances, minors may be found guilty of contributory negligence as a matter of law
2
. However, it is clear “ ‘that the same standards do not apply in the case of an infant of tender years and an adult, so far as the doctrine of contributory negligence is concerned. For no court can hold that childhood and manhood are bound to observe the same degree of diligence.’ ” Jackson v. Butler,
Since “(t)hére is no fixed rule of law by which to gauge, or scále by which to nicely weigh, the'acts of "a minor to determine if he is guilty of contributory negligence” [Jackson v. Butler, supra, 155 S.W. loc.cit. 1079], and since, in each case, not only the age of the minor but also “the peculiar circumstances of the particular case, the knowledge and, experience of the child in reference to those circumstances, and his capacity to appreciate the danger” must be taken into consideration [Moeller v. United Rys. Co.,
In our view of the case, we need not extend this opinion by discussion of defendant’s complaint that plaintiff's signed statement of April 28, 1952, was improperly excluded from evidence. For, the statement in question is included in the transcript on appeal, and we have considered it in our review of the case, as we are permitted to do. Section 510.310(4). The only portions of this signed statement, to which defendant’s counsel referred in trial of the case, or which differed from plaintiff’s oral testimony, have been hereinbefore quoted. Even if plaintiff’s signed statement were accepted literally and in its entirety, it would not establish that plaintiff was guilty of contributory negligence as a matter of law and would not change materially, or in any important respect the factual situation presented by the oral testimony. We are enjoined by statute that “(t)he judgment shall not be set aside unless clearly erroneous” [Section 510.310(4); Cosentino v. Heffelfinger,
The trier of fact, in this instance the trial judge, having had plaintiff before him, was in better position than we are, “from his (plaintiff’s) manner on the stand of testifying, from his appearance, intelligence, and other facts, to say whether, as to the danger to which he exposed himself, he shall be judged as a child or as a man full grown.” Jackson v. Butler, supra, 155 S.W. loc.cit. 1081. No question having been raised by defendant concerning the amount of the judgment, and being mindful that “due regard shall be given to the opportunity of the trial court to judge of the credibility of the witnesses” [Section 510.-310(4)], we have concluded, after however independent examination of the record which confirms the propriety of the trial court’s finding, that the judgment should be affirmed. It is so ordered.
