Claim:
A caster mounting assembly for coupling a rotating disc to a drill assembly used to furrow a field, the caster mounting assembly comprising: a screw extending through a stationary arm adapted to be coupled to the drill assembly; a movable arm adapted to be coupled to a shaft extending centrally through the rotating disc and coupled to a center hub; the rotary disc carries a scraper blade mounted opposite the hub; said screw having a threaded body extending from a head; said stationary arm having a threaded bore adapted to securely receive said screw when threaded therein; the threaded body terminates in a flat end against the moveable arm; and a pivot connection interconnecting the stationary arm and the movable arm that allows the movable arm to pivot about a first connection; wherein the stationary arm and the moveable arm are oriented such that the pivot connection is forward of the hub relative to the direction of travel; wherein the pivot connection allows the moveable arm to caster away from the stationary arm when the drill assembly turns counterclockwise; wherein a leading edge of the rotary disc will drive into the soil and torque placed on the leading edge will be countered by movement of the moveable arm away from the stationary arm to relive torque applied on the rotary disc.
