ABSTRACT:
Ground preparing apparatus for seed planting comprising a frame adapted to be drawn along a field by a tractor or the like connected to the leading end of the frame and with a planting machine connected to the trailing end of the frame. A colter disc rotatably carried by the frame penetrates the ground to form a slit in the ground and cut stalks and like debris. A pair of laterally and longitudinally spaced narrow tooth elements carried by the frame between the colter disc and the trailing end of the frame penetrate the ground on opposite sides of the slit and cut the ground to form a band-like region of ground prepared to receive seeds and the like dispensed by the planter. A pair of wheels rotatably connected to the frame contact the ground and are located between the tooth elements and the trailing end of the frame and are laterally spaced from the band-like region for controlling the depth of penetration of the colter disc and tooth elements into the ground. The frame includes a first assembly connected at opposite ends to the tractor and planter, respectively, and a second assembly carrying the colter disc, teeth and wheels and held by the first frame assembly through flexible couplings. The leading end of the second frame assembly is connected to the first assembly in a manner permitting a degree of movement of the end of the second assembly substantially perpendicular to the ground.
