Patent ID: 6860335

Claim:
In a farm implement having a tool beam swingable from a field position extending transversely of the path of travel of the implement to a folded position generally in line with said path of travel, said beam being supported at least in part by a gauge wheel assembly adjacent an outer end of the beam, the improvement comprising: said gauge wheel assembly being shiftable around said outer end of the beam from an inboard position when the beam is in its field position to an outboard position when the beam is in its folded position, said gauge wheel assembly including a ground-engaging wheel capable of reacting to ground forces during swinging of the beam for aligning the wheel with the path of travel of the implement in both positions of the beam, said wheel of the gauge wheel assembly having an upright swivel pivot about which the wheel swivels as the wheel reacts to ground forces during swinging of the beam, said swivel pivot being shifted around the outer end of the beam with the gauge wheel assembly when the gauge wheel assembly is shifted between its inboard and outboard positions.
