1. A field implement comprising:
- a frame supported for movement over a ground surface in a first linear direction and a second linear direction opposite the first linear direction;
a roller rotatably supported on the frame for rotation about an axis of rotation;
drive coupled to the roller for selectively rotating the roller in a first rotational direction about the axis of rotation when the frame is moving in the first linear direction and second rotational direction about the axis of rotation when the frame is moving in the second linear direction; and
a guard selectively mounted to the frame on an end of the roller in a first position or a second position, wherein the guard extends in the first linear direction for movement of the frame in the first linear direction while in the first position and in the second linear direction for movement of the frame in the second linear direction while in the second position.

Abstract
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.

13. A field implement comprising:
-
a frame supported for movement over a ground surface in a first linear direction and a second linear direction; a roller rotatably supported on the frame for rotation about an axis of rotation; a drive coupled to the roller for selectively rotating the roller in a first and second rotational direction about the axis of rotation; a deflector assembly adjustably fixed to the frame above the roller and having a first deflector facing the first linear direction to deflect material in front of the roller for movement in the first linear direction and a second deflector facing the second linear direction to deflect material in front of the roller for movement in the second linear direction;
wherein adjustment of the deflector assembly on the frame simultaneously adjusts a distance between the deflectors and the roller. - View Dependent Claims (14, 15, 16)
