Abstract: A stop mechanism for selectively varying the turning angle of an agricultural tractor is disclosed. The stop uses a series of limit tabs, one or more of which may be positioned between two abutments on a knuckle and yoke to provide a number of discrete adjustment points for the turning angle. The tabs are fixed to the steering components, readily movable to a position between the abutments, and semi-permanently attached to the tractor thereby allowing quick adjustment of turning angle without the need for loose parts.

Abstract: A quick coupler latch mechanism includes a latch pivoted on a quick coupler frame above a hook having a recess. A guide pin extends horizontally through the frame and is supported by thickened frame parts to resist bending deformation of the guide pin. An operator-controlled lever device moves a control bar within the frame. A guide member is rigidly fixed for movement with the lower end of the control bar and has a recess which slidably receives the guide pin. The guide member operatively engages the latch to pivot it between open and closed positions.
