Abstract:
Wheel structure for attachment to a transversely extending frame member of an implement supporting tools and adapted to be stored in a parked position, towed forwardly over the ground in a raised transport position, and towed forwardly over a field in a lowered working position with tools engaging the soil, the wheel structure comprising:a wheel frame; bracket structure for selectively attaching the wheel frame at one of a plurality of positions along the frame member; a rearwardly extending lift wheel structure pivotally connected to the wheel frame; forwardly extending gauge wheel structure connected to the wheel frame forwardly of the lift wheel structure; and a lift motor connected between the bracket structure and the lift wheel structure and operable to pivot the lift wheel structure to move the implement between the raised transport position and the lowered working position, wherein in the lowered working position the gauge wheel structure and the lift wheel structure support the frame member and resist torsional moments caused by the engagement of the tools with the soil and in the transport position the lift wheel structure supports the implement with the gauge wheel structure raised from the ground.
