ABSTRACT:
A single pass fracture planting system comprised of a tractor which tows a subsoil fracture tiller and a drawn multi-function planter drawn by a unique hydraulically controlled hitch system. The tractor draws a subsoil fracture tilling system comprised of a plurality of plows which fracture the soil to a depth of approximately one and a half feet while leaving surface residue largely undisturbed. The suboil fracture blades are mounted on a platform having a storage tank for anhydrous delivered to the soil through tubes mounted on the shanks of the fracture tiller blades. A multi-function drawn planter is drawn behind the subsoil fracture tiller by a hitch system having a hydraulically controlled drawbar. The hitch system is comprised of a frame having a drawbar pivotally mounted and hydraulically damped at one end with the opposite end being free to swing from side to side in a controlled fashion. Drawbar locking hydraulic cylinders center the planter during a planting pass.
