Transmission/Hydraulic/Axle Fill Tube

A - Full Hot Mark

B - Full Cold Mark

C - Min Cold Mark

D - Do Not Start Mark

E - Transmission Fill Tube

SERVICE INTERVAL — DAILY OR 10 HOURS

NOTE: The hydraulic oil reservoir does not hold the total system hydraulic oil capacity. The transmission, hydraulic reservoir and front and rear axles are included in the system.

IMPORTANT: Poor shift quality and/or transmission damage may occur if the HY-GARD or JDM J20C specifications are not followed. To ensure proper shift quality, an oil meeting HY-GARD or JDM J20C specifications must be used.

Do not operate tractor if oil level is at or below the “Do Not Start” mark (D) in sight gauge with engine off.

NOTE: Do check first thing in the morning when everything is "cold". Cold means when the ambient temperature is no lower than 7° C. (45° F.)

1. Check tractor and implement for leaks before daily start-up.

2. Tractor should be parked on level ground and implement lowered to the ground.

3. Transmission lever should be in PARK.

4. Start the engine and leave engine speed set at 1200 rpm for 5 minutes.

5. Transmission lever should remain in PARK.

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

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

   NOTE: As the tractor and hydraulic system get hot, the oil level will rise (increase) in the reservoir.

   As ambient temperature falls below 7° C. (45° F.), oil flows into axles and not return until tractor motion warms oil, resulting in a change to the reservoir oil level.

   Oil level in the reservoir will fluctuate depending upon the volume of oil exchanged with an attached implement. The pressure sensor will send alert if pressure falls too low due to low oil level.

8. NOTE: With everything cold, the oil level should be between the Min Cold and Full Cold marks. The volume capacity between the “Min Cold” and “Full Cold” marks is about 11.4 L (3 gal). Estimate the volume that needs to be added (or removed). If the reservoir oil level is between Full Cold (B) and Min Cold (C) marks, tractor can be used for normal operation.

   If reservoir oil level is below the “Do Not Start” mark, add oil directly to the hydraulic oil reservoir. See CHANGING TRANSMISSION-HYDRAULIC-AXLE OIL—Powershift in Lubrication and Maintenance-1500 Hour Service Section 130 to remove right-hand cab panel.

   If HY-GARD Transmission-Hydraulic oil is required, estimate oil volume needed and add using the ground level fill tube (E) located at rear of the transmission. Replace the fill tube plug.

9. If oil level is above the Full Cold mark, remove oil to lower level to the Full Cold mark.

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

   NOTE: If oil is required to “top-off” the hydraulic reservoir, the volume can be estimated using the sight gauge marks and added to the transmission fill tube, unless oil level is below the “Do Not Start” mark (D). In this case oil needs to be added directly to the hydraulic reservoir.
