An on-the-go gear shifter includes a control handle movable along a slot to change gear ratios. The control handle has an upper part and a lower part hinged to the upper part. Detent openings connect with the slot for retaining the control handle in a selected position. A shaft underlays the slot in parallel relationship to the detent openings. The lower part of the control handle is mounted from the shaft for rotation about its axis, with the hinge axis at right angles to the shaft axis. A thrust collar is disposed on the shaft for axial movement. A thrust surface is provided on the upper part of the control handle. Movement of the control handle to disengage it from a detent opening causes the thrust surface to urge the thrust collar along the shaft axis. A first link translates the movement of the thrust collar for the control of the clutch of the appliance. A second link connects the control handle to the gear box for changing the gear ratio as the control handle rotates about the axis of the shaft.
