<p>A control system (34) for a small work vehicle (10) such as a compact track propelled loader (10) has a control handle (94) that is mounted on to a swinging support plate (72). The support plate (72) swings about a vertical axis (82) positioned forwardly of the control handle (94), and the control handle (94) is mounted on the support plate (72) about a horizontal axis (98). Linkages (110, 112, 102, 116A, 116B) are provided between the control handle (94) and the pivotal mounting about the upright axis (82) to respective motor control levers (120A, 120B) for operating motors (36A, 36B) on opposite sides of the vehicle (10) for steering and propelling the vehicle (10). Moving the control handle (94) about the horizontal axis (98) causes drive selectively in forward and reverse direction, and moving the support plate (72) and the control handle (94) about the vertical axis provides differential movement for steering control.</p> |
