ABSTRACT:
A gang mower mountable on a tractor and having a plurality of independently-cutting mower units whose cutting heads are individually powered by hydraulic motors. Each mower unit is suspended from the end of a support arm which can move vertically through a distance of about 12 inches, each mower unit is itself mounted beneath a swivel ball joint that allows the mower to undergo pitch, roll and yaw motions as well as the up and down movements of the support arm. Moreover, this mower suspension mechanism allows each of the mower units to hold the ground due to its own weight alone and does not require any stabilizing force to be applied through springs or otherwise. The freedom of motion of the suspension mechanism in combination with an independent drive for each mower unit yields a gang mower with a smooth, wide-cut mowing action. Further, about half the mower units are mounted on foldable frame members, allowing the gang mower to pass through gates designed for auto travel and at the same time have a cutting width while in use as large as 19 feet. When the mower is attached to a suitable tractor, an operation which yields a near perfect cutting of turf at the rate of 15 acres per hour is easily accomplished.
