ABSTRACT:
A gauge wheel arm pivotally connected to an implement frame carries a first slotted plate, and a second slotted plate is fixed to the frame with the slots of the respective plates overlapping to receive a single bolt at the area of overlap. The slots, which provide for continuous adjustment of the arm, are angled with respect to each other to provide a scissors- or ramp-type action on the bolt which positively fixes the arm relative to the frame.
