    摘要: 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.

    摘要: A guide mechanism for controlling the pivotal positioning of a hydraulic control lever on tractors is disclosed wherein the guide mechanism incorporates a positive neutral lock in the form of a tab that is projectable into an opening within the control lever that is alignable therewith when in a neutral position. The guide mechanism includes a thumb wheel portion that projects upwardly through the control panel for manipulation by the operator for selectively rotating the guide mechanism to align a slotted opening therein with the control lever to limit the movement thereof in a preselected manner. The guide member is rotatable to four orientations to correspond to a neutral lock position, a float lockout position, a hydraulic motor mode position, and an unrestricted free range of movement position for the control lever.
