ABSTRACT:
A centering mechanism for the hydrostatic drive system of an articulate loader includes an actuating mechanism disposed between the pedal control and the output pump of the loader which returns to a centered or neutral position when the pedal control is released. A pair of torsion springs bias the actuating mechanism in opposite rotative directions to maintain the control in a centered or neutral position.
