| 20090114406 | HARROW FRAME AND HARROW FORMED THEREWITH - A harrow frame may be operable to permit pivoting of its ground working tool support arms between a first relative angle and a second relative angle. Pivoting may be achieved through a drive system and a lock controllable remotely such that the tool support arms can be pivoted about their fulcrums “on-the-fly” while the harrow frame is being moved along a ground surface. In addition or alternately, a harrow frame may also be folded to have a width less than 8.5 feet to facilitate transport. | 05-07-2009 |
