Claim:
1. A wheel assembly for supporting a frame of a pick-up of an agricultural machine on the ground, comprising: a beam, a support wheel rotatably mounted on an axle carried by the beam, a stub shaft on the beam receivable in a hole in the frame for releasably mounting the beam on the frame of the pick-up such that the beam is pivotable about the stub shaft with respect to the frame when received in the hole, and a locking mechanism connected to the beam for selectively radially locking the beam in a desired position relative to the frame to set the height of the frame above the ground; and a retention plate on the end of the stub shaft having at least one arm radially projecting beyond the circumference of the stub shaft, and the hole in the frame for receiving the stub shaft including at least one radial recess dimensioned to permit the retention plate and the at least one radially projecting arm to pass through the hole when aligned with the at least one recess in a first position, the at least one arm movable to a second position when inserted through the hole preventing the stub shaft from moving axially relative to the frame when misaligned with the at least one recess.
