ABSTRACT:
A tractor balancing device capable of providing vertical support to the frame of a side-mounted bush hog. The balancing device consists of an inflatable and deflatable air bag secured between a platform placed above the right, front axle of a bush hog tractor, and a bracket affixed to the frame of the side-mounted bush hog. The air bag is connected to an air compressor and receives air by means of an air hose. A system of pressure regulation is provided so as to control the level of air pressure within the air bag. If, during operation of the bush hog, either the moment of the bush hog arm or the incline of the surface causes the tractor to tilt in the direction of the bush hog arm, the air bag can be inflated. This stiffens the frame of the bush, preventing it from pivoting and tilting the tractor. The moment applied to the tractor is reduced by virtue of the upward force applied by the air bag onto the frame of the bush hog. The air bag can be deflated when the bush hog is not in use, or when the bush hog tractor is in danger of tilting away from the bush hog arm. Thus, the inflation and deflation of the air bag serves to balance the tractor.
