    Hydraulic Reservoir

    A - Retaining Screws

    B - Side Panel

    C - Reservoir Fill Cap

    Remove right-hand cab panel retaining screws (A) and remove side panel (B).


  18. NOTE: The hydraulic reservoir will not hold the total oil volume for the system until engine is started and oil is circulated to transmission and axles, resulting in a lower reservoir oil level. The reservoir will need to be the correct level.

    Remove reservoir fill cap (C) and fill the hydraulic oil reservoir with the remaining oil volume using John Deere Hy-Gard or JDM J20C oil. Reinstall reservoir fill cap.

  19. Put transmission in PARK position and operate engine at 1200 rpm, to circulate oil to axles.

  20. Operate engine at 1200 rpm for approximately 5 minutes or until oil appears at axle ports.

  21. Shut engine OFF and install both axle plugs.

  22. IMPORTANT: Shut engine OFF and add more of remaining oil volume to reservoir if oil level drops to "Do Not Start" mark. Then resume operation of tractor at 1200 rpm per fill procedure.

    Check hydraulic oil reservoir sight gauge and top off reservoir to “Full Cold” mark. Reinstall reservoir fill cap.

  23. Transmission lever should be in PARK.

  24. Start tractor and set engine speed at 1200 rpm for 5 minutes.

  25. Transmission lever should remain in PARK.

  26. Shut engine OFF and wait 5 minutes for oil level to stabilize.

  27. NOTE: Do not reinstall right-hand cab side panel until after engine is started and oil circulated throughout hydraulic system and oil level in sight gauge has stabilized.

    Reinstall and tighten hydraulic reservoir fill cap.

    Transmission/Hydraulic/Axle Oil Reservoir

    Transmission Fill Tube

    A - “Full Hot” Mark

    B - “Full Cold” Mark

    C - “Min Cold” Mark

    D - “Do Not Start” Mark

    E - Transmission Fill Tube

    Check oil level using hydraulic reservoir sight gauge located on right side of the cab.

    With everything cold, oil level should be between Min Cold (C) and Full Cold (B) marks.


  29. NOTE: The volume capacity between “Min Cold” and “Full Cold” marks is about 11.4 L. (3 gal.)

    Estimate volume that needs to be removed (or added).

    If reservoir oil level is visible between Min Cold (C) and Full Cold (B) marks, tractor can be used for normal operation.

    Identify oil volume required in reservoir until it reaches marks Min Cold (C) or Full Cold (B). If oil level is below (C) in sight gauge, add HY-GARD Hydraulic Oil through reservoir fill cap for 1500 Hour service procedure.

    For daily checks or top off, if sight gauge is below Min Cold (C) mark but above Do Not Start (D) mark, add required volume of HY-GARD Transmission-Hydraulic Oil using fill tube (E), at rear of transmission.

    If oil volume required is below the Do Not Start mark, add required oil through hydraulic reservoir fill cap.

    IMPORTANT: DO NOT start engine if oil level is below “Do Not Start” mark (D).

    NOTE: An exception is implements with large hydraulic cylinders that can remove large volumes of oil from the tractor's hydraulic system. Oil level should be near bottom mark of sight gauge with implement positioned to contain maximum amount of oil.

    NOTE: Oil level in reservoir will rise as temperature increases.

    Oil level in reservoir will fluctuate depending upon volume of oil exchanged with an attached implement.

    If low oil level results in pressure drop, a STOP engine light will come on.

  30. The hydraulic reservoir oil level checking procedure should be repeated and oil level adjusted until oil level stabilizes between Min Cold (C) and Full Cold (B) marks.

  31. If oil level is above Full Cold (B) mark, remove oil to bring it down to Full Cold mark level.

    The recommended method to remove oil is use the drain valve at rear of the reservoir, in hinge area under cab. A hose can be attached to the drain valve to direct oil into a container.

  32. Reinstall the right-hand cab side panel and tighten using retaining screws.
