Abstract
An elongated frame rests on the ground in the path of a self-propelled sprinkler wheel. The wheel rides up onto a pair of rollers on the frame to prevent the wheel from obtaining traction and another roller on the frame engages the front of the wheel to positively block further forward movement of the sprinkler.
