Abstract:
A twin-lever drive wheel steering mower for a sitting operator with each lever independently controlling the speed of each drive wheel through a separate hydraulic pump and motor transmission comprising:a frame supporting two drive wheels; a pair of variable flow hydraulic pumps controlled by a rotatable swash plate, each pump is connected to a drive wheel through a hydraulic motor, each hydraulic motor driving one of a pair of drive wheels in forward, reverse, and neutral conditions; a braking member acting on each drive wheel; a pair of steering levers pivotally mounted on the frame for longitudinal movement in forward and reverse conditions and lateral outward movement in a neutral condition, with each steering lever controlling one of said pumps, each steering lever is connected independently to its pump to produce variable speeds forward and reverse, and a neutral position; linkage members interconnecting the steering levers for each wheel and an associated brake whereby in said neutral position, lateral outward movement of the steering lever actuates the brake.
