Abstract: A coulter wheel assembly for mounting to a farm implement having a frame. The assembly includes a vertical shank having a coil spring at substantially its mid-point and upper and lower shank members extending therefrom. The upper shank member is attached to the frame by means of a mounting bracket and the lower shank member is attached to a rotatable hub. A coulter wheel for engagement of the soil is mounted on the hub. The coulter wheel assembly is used, for example, with no-till planting equipment in order to prepare the soil prior to seed introduction. In operation, the coulter wheel rotates along the ground, thereby penetrating the soil, and is permitted to deflect in response to impact with obstructions by means of the coil spring; the coulter wheel then returns to its original path, thereby providing a uniformly prepared soil surface and preventing damage to the coulter wheel assembly or the implement.
