Abstract
A hydrostatic transmission utilized in a tractor that drives a mower attachment. The hydrostatic transmission includes a control shaft that is operated through a linkage system from a shift control lever. An adjustable detent operates directly on the control shaft for locking the control shaft in its neutral condition. The linkage system includes a lost motion connection so that the detent can operate without having to move the linkage system or the shift control lever.
