ABSTRACT:
A drawbar apparatus for use in a wheeled fertilizer tank which is normally coupled between a tractor and a planter. The drawbar apparatus includes a housing integral with the chasis of the wheeled fertilizer tank and a drawbar pivotally attached at the front end of the housing adjacent the coupling to the tractor. The drawbar extends between the front and rear ends of the wheeled fertilizer tank and includes a coupling means at the rear end for coupling to the planter. The housing includes a guide means for limiting the verticle and lateral movement of the drawbar. The drawbar pivots relative to the wheeled fertilizer tank in response to relative tilting between the tractor and the wheeled fertilizer tank, thus permitting the planter to dig a furrow having a constant depth as variations in terrain are negotiated.
