Abstract
The disclosure relates to a self-centering and dampening hydrostatic transmission linkage. The invention consists of a pivot link that is pivotally attached to an isolator plate. Connecting the isolator plate to the pivot link is a centering damper. An upper rocker arm and lower rocker arm connect the pivot link to the hydrostatic transmission system control pedal. The pivot link also has a hydrostatic transmission adjustment rod and an aperture. The movement of the pedal controls the movement of the rod which adjust the tractor transmission for either forward or rearward travel. When a no force is placed on the pedal, the centering damper moves the aperture into contact with an adjustable spring steel detent. This ensures that the tractor transmission will remain in neutral. The pedal is designed with a foot rest and two elongated pads. This allows the operator flexibility when using the tractor for a variety of farm operations.
