      • 1. Make sure the tractor is equipped with the correct PTO shaft. Change shafts if needed.
      • 2. Shorten or remove the tractor drawbar to avoid interference when raising and lowering the mower.
      • 3. Board the tractor and start the engine. Position the tractor to the mower with the 3-point lift arms positioned between the r...
      • 4. Turn off the tractor engine and dismount.
      • 5. One lift arm at a time, align arm end hole between the set of A-frame lift lugs. Insert hitch pin through the lug and arm holes and insert retaining pin into hitch pin.
      • 6. Walk around to opposite side and repeat procedure for remaining lift arm and hitch pin.
      • 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.
      • 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.

        • 3. Shut down the tractor and remove the key.
        • 4. Level the mower deck front to rear by extending or retracting the 3-point top link.
        • 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.
        • 6. Securely block up the mower at this height.
        • 7. Remove the bolts securing the tailwheel beam positioning bracket to the support brackets and allow the tailwheel to rest at g...
        • 8. Extend the tractor’s top 3-point link so that when lifting the mower, the front of the deck will raise 2 to 2º" before the tail wheel leaves the ground. This will allow the mower to follow the contour of uneven terrain.
