ABSTRACT:
Stabilizng arms are applied to an agricultural tractor having a three point hitch with a quick hitch frame. Specifically, a belly plate is added to the frame beams about half way between the front axle and the rear axle. A horizontal frame draw bar extends from the belly plate to a pivot pin mounted by a clamp below the rear axle housing. The stabilizing arms extend from the pivot pin below the axle housing back to a quick hitch frame pin, which is an extension of the quick hitch pin and extends outboard of the quick hitch frame on each side thereof. A cross brace extends between the stabilizing arms to form a rigid stabilizing frame. Because the pivot pin below the axle is not coaxial with the pin by which the normal draft links are connected to the differential housing of the tractor, it is necessary that the stabilizing arms be pivoted so that the quick hitch frame can be mounted to have its normal motion to raise and lower the tillage implements connected to the quick hitch frame.
