ABSTRACT:
A turn assisting mechanism assists a turning motion of a vehicle, such as a lawn mowing vehicle, so that the vehicle may not damage the ground (lawn grass, crops, etc.) when the vehicle makes a U-turn. The turn assisting mechanism is disposed near a wheel of the vehicle nearest to the center of turning of the vehicle about which the vehicle makes a U-turn. The turn assisting mechanism stretches out the rod of a hydraulic cylinder actuator to set a ground contact unit on the ground and lifts up the wheel nearest to the center of turning of the vehicle. When the vehicle makes a U-turn, the hydraulic cylinder actuator sets the ground contact unit on the ground so that the axis of turning of the ground contact unit passes the center of turning of the vehicle, and lifts up the corresponding wheel from the ground. The vehicle makes a U-turn on the ground contact unit without damaging the ground.
