Abstract
An improved shifting device for the hydrostatic transmission of a lawn tractor or the like. The shifting device includes means for permitting a greater latitude of movement of the shift lever without effecting either forward or reverse movement. This is done by incorporating a linkage system for interconnecting the shift lever with the transmission control that includes a lost motion connection and by providing a leak path in the hydrostatic transmission so that a greater than normal pressure must be exerted before drive in one direction is possible.
