摘要: An implement for preparing a field includes a ground engaging device that allows the implement to be pushed or pulled on the field. The ground engaging device includes a reversible roller with projections joined to an outer surface thereof to engage the ground. The projections do not extend along the complete length of the roller but rather a portion thereof thereby reducing the power necessary to rotate the roller. The implement includes reversible guards for keeping the disturbed ground in front of the roller.
