A transmission speed range selector valve pressure biased to the high speed range position and spring biased toward the low speed range position. A detent mechanism for retaining the valve in the low speed range arrests the movement of the valve when the pressure of the pressure biasing fluid decreases allowing the spring to move the valve toward the low speed range and thereby downshift the transmission when fluid is throtted to the speed range selector valve.

Detent mechanism and transmission speed range selector valve

A mechanical detent release for a power shift transmission selector valve operating through a mechanical linkage connected to the clutch pedal operating the inching valve. The mechanical detent releases in response to a spring in the transmission selector valve spool engaging a cam on the clutch pedal of the inching valve which permits the selector valve to return to the low speed position when the inching valve is operated.

Mechanical detent for three speed power shift transmission

An adjustable lift link on a three-point hitch having a self-locking handle and retainer for selectively adjusting and holding the adjustment of the lift link. A stop on the link selectively provides the float or fixed length positions of the link of the three-point hitch.
