          61
        • 3. Board the tractor and start the engine. Position the tractor to the mower with the 3-point lift arms positioned at the same height and to the outside of the mower hitch pins.

          61
        • 4. Turn off the tractor engine and dismount.

          62

          62
        • 7. Extend or retract 3-point top link to align its end hole with the holes of the mower’s top link. Insert the top link hitch pin and insert retaining pin into hitch pin.

          62
        • 8. Adjust any lower link check chains, guide blocks, or sway blocks to prevent the mower from swaying side to side and possible contact with tractor rear tires.

          64
        • 2. Using the 3-point hitch control lever, position the front of the mower with the side skids 1” less off the ground than desired cut height. For example, for a 3” cut, position the skids 2” from the ground. Set the 3-point control lever stop a...

          64
        • 3. Shut down the tractor and remove the key.

          64

          64
        • 5. Level the mower side to side by manipulating one lower lift arm length. On most tractors, at least one of the lift arms is designed to allow for manipulation of its length. Shortening or extending will allow for deck leveling from side to side.

          64
        • 6. Securely block up the mower at this height.

          64
        • 7. Remove the bolts securing the tailwheel beam in position and allow the tailwheel to rest at ground level. Align tailwheel beam between nearest sets of holes in beam support brackets and reinstall support bolts on each side of beam. Tighten all bol...

        • 8. Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2½” before the tail wheel leaves the ground. This will allow the mower to follow the contour of uneven terrain.

          65
    • 6.2 Connecting the Mower-Pull Type

      66
      • 1. Make sure the tractor is equipped with the correct PTO shaft and the drawbar is extended 14” from the end of the PTO shaft to the hitch point.

        66
      • 3. Board the tractor and start the engine. Back the tractor to the mower aligning the drawbar hitch hole with the mower hitch clevis. Turn off the engine, secure the tractor in position, and dismount.

        66
      • 4. To attach the mower, place two 1” flatwashers (1) positioned under top lip of tongue clevis and to the top of drawbar. Add additional 1” flatwashers (2) between the bottom of drawbar and bottom lip of clevis to fill open space. Insert a 3/4”...

        66
      • 5. Securely attach mower safety chain from mower tongue to tractor drawbar or drawbar support frame.

        66
      • 6. Lower the jack until the tongue is completely supported by the drawbar. Remove jack from the tongue and place on storage bracket of mower main frame.

        66
      • 7. If using a hydraulic cylinder, connect hydraulic hose ends into tractor hydraulic ports. Pressure may need to be relieved from the system to allow for ease of attachment.

        66
      • 8. If the mower has been attached to a 3-point hitch drawbar, adjust any tractor equipped lower link check chains, guide blocks, or sway blocks to prevent the hitch and mower from swaying side to side.

        67
      • 3. Adjust the mower leveling rod so that the front of the mower is approximately 3/4” lower than the rear.

        67
      • 4. If the mower is attached to a 3-point hitch drawbar, adjust any tractor equipped lower link check chains, guide blocks, or sway blocks to prevent the hitch and mower from swaying from side to side. Never raise the 3-point lift with the mower attac...
