.~.~ Drive in one direction by direct engagement of belt pulleys
Drive in one direction by direct engagement of belt pulleys:
(under subclass 16) Subject matter wherein said endless flexible member extends between and drivingly engages a pair of wheels; and wherein means is provided to provide direct driving contact between surfaces of said wheels to drive said output body in said clockwise or counterclockwise direction. [figure] [caption] Drive mechanism for a riding mower in which the power for driving the traction wheels of the vehicle and for driving the cutting units is transmitted from a common engine shaft. The power to the wheels is transmitted through a reversible transmission involving a coplanar driving and driven pulleys rotating on parallel axes and movable into and out of engagement with each other and drivingly interconnected by a belt wrapped around both pulleys. When the pulleys are engaged with each other, the belt is slack, and the driven pulley is driven in one direction. When the pulleys are disengaged, the belt is tightened and drives the driven pulley in the opposite direction. The power to the cutting units is transmitted from the engine through an intermediate shaft which is rotatably mounted on the wheel axle. At least two of the cutting units are in alignment and driven by a common coaxial drive shaft driven from said intermediate shaft.
