An implement operating apparatus has a drive frame supported on drive wheels, each pivotally mounted about a vertical wheel pivot axis. A steering control selectively pivots each drive wheel. A motor is mounted on the drive frame and connected through a drive control operative to rotate the drive wheels in a selected one of first and second directions. An implement rests on the ground and when the drive frame is maneuvered to an implement loading position with respect to the implement, the implement is connectable to the drive frame and movable to an operating position supported by the drive frame. When the implement is in the operating position, the steering and drive controls are operative to move and steer the drive frame and implement along a selected one of a first travel path and a second travel path oriented generally perpendicular to the first travel path |
