Abstract:
1. In a work vehicle having a motor driving a hydrostatic pump, the hydrostatic pump driving a hydraulic motor, wherein the hydrostatic pump comprises an operator-selectable forward drive position and a neutral position, and including an electrical interlock that prevents starting of the motor when the hydrostatic pump is not in the neutral position, the improvement comprising: the hydrostatic pump having an input control shaft, the rotation of which moves the hydrostatic pump from the neutral position to the forward drive position, a control arm fixed to the input control shaft, a linkage element fixed at one end portion to the control arm at a distance from an axis of rotation of the input control shaft and extending to an opposite end portion where it is engagable to be moved to selectively rotate the input control shaft via said control arm, a first arm mounted for rotation about said input control shaft axis and extending a radial distance from said input control shaft, a neutral start switch mounted to said first arm to orbit about said input control shaft axis with rotation of said control arm, said switch having an actuation portion that is arranged to be actuated to change states when said control arm is in said neutral position.
