ABSTRACT:
A weighting device is suspended beneath a tractor and between its wheels to improve the traction of the wheels and the stability of the tractor. The device has the general form of a flat, elongated element with a width substantially less than the spacing between the wheels of the tractor and which extends from at least the rear of the tractor to a point beyond the front of the tractor in order to carry weights which are utilized to prevent the tractor from rearing or lifting. The weight is suspended on the tractor by elements which include flaps, sliding shoulders integral with the tractor, sliding wing flanges and jacks. The jacks may be controlled by fluid distributors for driving the device, and therefore the weights, both longitudinally and transversely along a plane substantially parallel to the ground or other support surface.
