Abstract
A twin-lever drive wheel steering mower for a sitting operator with each lever independently controlling a brake and the speed of each drive wheel through a separate hydraulic pump and motor transmission. A brake positioned on each drive wheel; a pair of pivotally mounted steering levers, each controlling one of said pumps mounted on the mower for longitudinal movement, each steering lever is connected independently to the swash plate of its controlled pump providing variable speeds forward, reverse, and a neutral zero flow position; linkage members connecting the steering levers for each wheel to said brake on each wheel; a pair of T-shaped slots having a lateral leg in a cover plate surrounding each of the steering levers allowing the levers to move laterally outward in the lateral leg to engage the brakes only in the neutral position.
