ABSTRACT:
A loader coupler or other attachment includes first and second roll-back stops located on opposite lateral sides. The stops include a mounting location such as a boss, a bumper or stop member releasably secured to the mounting location, and optionally one or more shims disposed between the mounting location and the stop member. The number and thickness of the shims may be used to control the spacing of the first and second stop members from their respective mounting locations to thus control the angular position of the coupler when the stop members contact the respective arms of the machine carrying the coupler.
