Abstract
An agricultural implement designed for distributing anhydrous ammonia by laterally spaced applicator knives includes an elongated wagon hitch frame which has a forward end pivotally mounted to a forward section of the implement frame and a rear end which carries a drawbar and hitch clevis for a trailing wagon carrying a tank of anhydrous ammonia. As the implement is raised, the rear end of the wagon hitch frame drops away from the implement frame so that the height of the wagon hitch above the ground remains substantially constant and the implement hitch section and wagon tongue remain in line. The break-away coupler for the main hose from the anhydrous tank to the implement is provided with a swing arm to facilitate disconnection of the main hose even when the anhydrous wagon is sharply angled. In the case of a larger implement, having right and left pivoting wings, the frames of the wing sections are strengthened with efficient use of upper and lower laterally spaced channel stiffeners.
