  • Prestart Checklist
    • 1. Read and understand “Important Safety Information,” page 0.
    • 2. Check that all working parts are moving freely, bolts are tight, and cotter pins are spread.
    • 3. Check that all safety decals and reflectors are correctly located and legible. Replace if damaged. See Safety Decals, “Important Safety Information,”
    • 4. Inflate tires to pressure recommended and tighten wheel bolts as specified. See “Appendix,” page 7.
  • Hitching Tractor to Implement
    • 1. Place hitch weldment (1) over ball swivel on hitch tongue (2). Hold hitch weldment in place by inserting spacer tube (3) through hitch clevis and ball swivel.
    • 2. Back tractor up to hitch and bolt hitch weldment to tractor drawbar using 1-by-10-inch bolt (4), large flat washer (5), lock washer (6), and nut (7).
    • 3. Use 3/4-by-9-inch bolt (8) to bolt hitch weldment through its slotted hole and onto secondary hole of tractor drawbar. Install a 3/4-inch flat washer (9) next to top slotted hole and fasten with a lock washer (10) and nut (11). Tighten both bolts.

  • 4. Securely attach safety chain to tractor-drawbar frame.
  • 5. Remove jack from stob on side of hitch tongue and place in transport position on implement. See Figure 2-2.

  • 6. With center-pivot hitch properly secured to tractor drawbar, remove transport lock pins located in vertical tubes above tires and place in storage hole next to stabilizer cylinder on hitch as shown in Figure 2-3.

  • 7. Position the center pivot hitch in front of drill so quick- hitch links on hitch are in line with lower hitch pins on drill. Hydraulically retract transport-lift cylinders to position quick-hitch links slightly lower than drill hitch pins.
  • 8. Position quick-hitch handle to locking position as shown in Figure 2-4. This will allow drill hitch pins to snap into quick-hitch links and secure drill to hitch.

  • 9. Back center-pivot hitch up to drill until hitch pins contact quick hitch. Hydraulically raise hitch just until hitch pins are securely attached inside quick-hitch links. Do not raise drill any higher than necessary.
  • 10. Attach slotted link from center pivot hitch (1) to top hitch on drill. Using hitch pin (2) and bushing (3), secure with clip pin (4) as shown in Figure 2-5.

  • Bleeding Hydraulic Systems
    • 1. Check hydraulic fluid in tractor reservoir and fill to proper level. Add fluid to system as needed. Tongue cylinder capacity is 1.89 litres (one-half gallon).
    • 2. Raise and safely support hitch, transport frame and front tongue.
    • 3. Unpin rod end of tongue cylinder. Block, wire or otherwise safely support cylinder so when rod end is fully extended it does not contact anything.
    • 4. Cycle cylinder completely in and out at least three times to purge air from cylinder and hoses.
    • 5. Fully extend cylinder and repin rod end.
    • 6. Re-check tractor reservoir and fill to proper level.
    • 1. Check hydraulic fluid in tractor reservoir and fill to proper level. Add fluid to system as needed. Transport-lift-cylinder capacity is about 7.57 litres (2 gallons).
    • 2. Jack up and support hitch frame.
    • 3. Remove 1/2-inch nylock nuts (1) on spring side of cylinder-support brace. Unpin cylinders. Do not alter position of jam nuts (2) on centre of support-brace bolts.

• Unpin Cylinders
  • 4. Turn cylinders to a position where rod ends are higher than base ends. Support cylinders in a safe location.
  • 5. Start tractor and run engine at idle speed. With rod ends higher than base ends, hydraulically extend cylinders. After cylinder rods are fully extended, continue to hold control lever for one minute before hydraulically retracting cylinders.
  • 6. Repeat step 5 three times to completely bleed system. If air is still trapped in either cylinder, it will operate in jerky, erratic motions. Repeat steps until cylinder movement is smooth and even.
  • 7. Repin cylinders to hitch frame. Reinstall short compression springs on cylinder-support-brace bolts and re-tighten 1/2-inch n...
  • 8. Refill tractor hydraulic-fluid reservoir to proper level.
  • 1. Check that tractor hydraulic reservoir is full.
  • 2. With both markers lowered into field position, loosen hydraulic-hose fittings at rod and base ends of marker cylinders. Loosen fittings on back side of sequence valve.
  • 3. With tractor idling, activate tractor hydraulic valve until oil seeps out around a loosened fitting. Tighten that fitting.
  • 4. Reactivate tractor hydraulic valve until oil seeps out around another loosened fitting. Tighten that fitting. Repeat process until all loosened fittings have been bled and tightened.

  • Pre-Assembly Checklist
    • 1. Read and understand “Important Safety Information” on page 0 before assembling.
    • 2. Have at least two people on hand while assembling.
    • 3. Make sure the assembly area is level and free of obstructions (preferably an open concrete area).
    • 4. Have all major components.
    • 5. Have all fasteners and pins shipped with the drill.
    • 6. Have a copy of the parts manual on hand. If unsure of proper placement or use of any part or fastener, refer to the parts manual.
    • 7. Check that all working parts are moving freely, bolts are tight, and cotter pins are spread.
    • 8. Check for proper tension and alignment on all drive chains.
    • 9. Check that all safety labels and reflectors are correctly located and legible. Replace if improperly located or damaged. Refer to Safety Labels, “Important Safety Information” in the operator’s manual.
    • 10. Inflate tires to recommended pressure as listed on the Tire Inflation Chart on the “Appendix” on page 7. Tighten wheel bolts as specified on Torque Values Chart on the “Appendix” on page 7.
