    • ASSEMBLY
      • 1. Use the implement jack to raise the implement tongue until it is even with the tractor drawbar. Insert the jack into the jack adapter in the implement tongue and swivel it so that it is vertical. Follow the instructions on the jack. Install the ja...
      • 2. Make sure the tractor PTO is the correct speed and shaft size for the implement. Ensure the drawbar is extended the proper distance from the Tractor PTO shaft for desired PTO speed; 540 PTO is 14” and for 1000 PTO speed the distance is 16”
      • 3. Carefully back tractor to mower. Do not allow coworkers or bystanders between the tractor and the implement while backing. When dismounting the tractor ALWAYS shut down the tractor, disengage the PTO, and set the parking brake before dismounting.
      • 4. Install the retaining bolt through tongue clevis and tractor drawbar. The implement tongue is very heavy. Make any height adjustments using the implement jack. Place two 1” flatwashers (1) positioned under top lip of tongue clevis and to the top...
      • 5. Install the implement tow chain to a secure location on the tractor.
      • 6. Attach proper hydraulic couplers to implement hose ends. Insert the wing hose quick disconnect couplers into tractor hydraulic remotes.
      • 7. Mount tractor, fasten your seatbelt and start engine. From the operators seat use the tractor hydraulic control levers to fill wing cylinders with oil. Filling the cylinders should retract the wings slightly to their minimum closed width. Continue...
      • 8. Remove retaining bracket from end yoke of main driveline. Remove main driveline from mower and place on ground or hard surface. Figure AsmP-R-0120
      • 9. Make sure the wing Transport Bars/Latches are locked in the position to hold the wings vertical before removing shipping strap. Figure AsmP- R-0118
      • 10. Stand between the wings of the implement and remove nuts holding the shipping strap in place and remove strap.
      • 11. Filling the cylinders with oil should raise the wings slightly and loosen the wing Transport Bars/Latches retaining pin. NOTE: DO NOT release the wing Transport Bar/Latch if there is a force on the pin. If there is a force holding the Transport B...
      • 12. From the tractor seat use the tractor hydraulic control levers to lower the wing(s).
      • 13. Continue to hold the control lever until both wings are down and the wing cylinders are fully extended. Continue to cycle the cylinders several times by raising and lowering the wings fully to remove any trapped air. If there is sponginess during...
      • 14. Test to make sure the wings lower slowly when they are allowed to float down and are not powered down. This is a safety feature built into the system. If the wings fall rapidly, have the hydraulic system or cylinders repaired before operating the...
