A multi-directional single lever control for a transmission with at least two modes of operation comprises two juxtaposed sets of speeds correlating to these modes. The shift lever pivoting with a lever mount in one direction engages speeds working in one mode and pivoting about the lever mount selectively engages oppositely aligned speeds in either mode of operation. A switch actuated by the shift lever rotation about the mount lever controls, a valve assembly for rerouting fluid flow into passages corresponding to a selected mode of operation.

Multi-directional single lever control for transmissions

A self-locking portable panel having an impact actuated and self-locking hinge mechanism at one end thereof and a latch at another.

A park lock interlock control system preventing the shifting of the vehicle transmission in gear positions when the drive train park lock is engaged. A two part interlock system comprises a park lock control including a crossover shaft and a transmission shift lever connected with a plate having a slot. The shaft projecting through the slot is able to rotate, thereby engaging or disengaging the drive train park lock, only when the shift lever is put in a neutral position, thus preventing an accidental transmission engagement in gear when the park lock is actuated.

Park lock interlock control system

Individual rotary flow control valves associated with and metering hydraulic fluid flow through one or more directional control valves mounted on a tractor frame are connected by flexible push-pull cables to respective control sectors located adjacent the tractor seat so that an operator may control the flow rate to a remote hydraulically driven or adjusted implement from the tractor seat.
