A tractor is provided with a main frame, a blade, and a C-frame which has a pair of substantially parallel spaced apart legs joined together at one end portion thereof, each leg of the C-frame has a curved portion extending upwardly and away from said leg. Each curved portion of the C-frame is pivotally mounted to the main frame of the tractor. The C-frame is operatively connected to said blade whereby forces engaging said blade are transmitted through the C-frame directly to the main frame of the tractor.
