ABSTRACT:
A shift mechanism for a multi-speed transmission of an off-highway implement. The shift mechanism includes an in-line shifter assembly that connects to first and second actuators on the transmission. The shifter assembly is configured to shift the transmission between speed ratios under one-handed control and comprises a first controller that is movable along a monoplanar path of travel and a second controller that is carried by the first controller and is movable between two vertical positions. The shifter assembly is connected to a selected one of the transmission actuators as a function of the vertical position of the vertically movable controller. Back and forth movements of the other controller moves the selected one of the transmission actuators into a position which conditions the transmission for operation in a selected speed ratio. The shifter assembly is pivotally mounted on a housing to form a modular unit that can be mounted at the work station of the implement and thereafter is connectable to the transmission actuators through suitable force transfer mechanisms.
