their amended complaint against Auburn, the Joneses alleged negligence, breach of warranty, and strict liability arising out of the alleged defective manufacture and design of the trencher. They alleged that Auburn failed to provide reasonable safety features, shields, and guards on moving, exposed, and dangerous portions of the machine; that Auburn failed to design and manufacture the trencher so that the driver or operator could adequately view the operation of the machine’s dangerous moving parts; and that Auburn failed to furnish adequate operation instructions. The amended complaint further alleged that Auburn impliedly warranted to ultimate users of the trencher that it was fit for its intended purpose and was safely designed; that the trencher, however, was not of merchantable quality because of its lack of safety devices; and that Auburn was strictly liable in tort. Proximate cause was alleged on all counts.
Auburn filed a motion for summary judgment. In opposition to this motion, the Joneses filed an affidavit of an expert witness testifying that the trencher’s design constituted a departure from the reasonably safe and sound engineering practice at the time of its manufacture. The witness stated that the placement of the trencher upon the tractor by Auburn constituted a departure from reasonably safe and sound engineering practice at the time of its manufacture in that Auburn failed to equip the tractor with a rearview mirror which would allow the operator to see the trencher in operation; that Auburn failed to have a library containing safety and design standards at the time this machine was manufactured; that the machine was manufactured without any thought to prevailing safety requirements for the trencher; that the trenching boom was not guarded or shielded, leaving an exposed chain; that a guard or shield probably would have prevented the accident; and that such guard or shield was available at the time this trencher was manufactured or prior to the time of the accident. The trial court entered summary judgment for Auburn, and the Jones-es appealed.
Holding that Auburn as movant failed to meet its burden of showing conclusively that no genuine issues of material fact existed, the Second District reversed the trial court’s order granting summary judgment; and, referring to its earlier decision in Watson v. Lucerne Machinery & Equipment, Inc., 347 So.2d 459 (Fla. 2d DCA 1977), it refused to adopt the obvious and patent danger rule espoused by the First District in Farmhand, Inc. v. Brandies, supra.
Auburn, relying primarily upon Farmhand and Campo v. Scofield, 301 N.Y. 468, 95 N.E.2d 802 (1950), argues that we should apply the patent danger doctrine and contends that this doctrine is based upon sound principles. In response, the Joneses argue that we should reject this doctrine and hold that the obviousness of the hazard is merely an element to be considered in the determination of contributory fault.
The most cogent statement of the patent danger doctrine is found in Campo v. Scofield, supra. In that case, the New York Court of Appeals stated:
[T]he manufacturer of a machine or any other article, dangerous because of the way in which it functions, and patently so, owes to those who use it a duty merely to make it free from latent defects and concealed dangers. .
If a manufacturer does everything necessary to make the machine function properly for the purpose for which it is designed, if the machine is without any latent defect, and if its functioning creates no danger or peril that is not known to the user, then the manufacturer has satisfied the law’s demands.
301 N.Y. at 471-2, 95 N.E.2d at 803-04.
The First District in Farmhand applied the patent danger doctrine as enunciated in Campo v. Scofield to the facts of the case before it because it believed the doctrine to be the controlling law in Florida at the time it rendered its decision, holding that the doctrine barred the plaintiff’s negligence and breach of warranty claims. The First District recognized,, however, that its decision in Farmhand passed upon a question of
