Transmission-Hydraulic Oil Level

Poor shift quality or transmission damage may occur if incorrect oil is used, see Transmission and Hydraulic Oil in Other Lubricants section of this Operator’s Manual.

Transmission-Hydraulic Oil Sight Gauge

If topping off oil in hydraulic reservoir, use sight gauge marks to estimate volume and add to transmission fill tube.

Hydraulic oil reservoir does not hold all system hydraulic oil capacity. Transmission and front and rear axles hold additional system oil. If possible, check oil level prior to first start of day. Ambient temperature should be 7° C (45° F) or above.

For implements and applications requiring high volumes of oil transfer (for example - large air seeders or pulling 3 scrapers), hydraulic reservoir can be filled up to High Volume Takeout Oil Mark (D). Additional capacity is 58.5 L (15.4 gal) above MIN COLD (C).

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

2. Park tractor on level ground with implement fully lowered.

3. Place transmission shift lever in PARK.

4. Start engine and set engine speed set to 1200 rpm.

5. Run engine for five minutes.

6. Shut off engine and wait five minutes for oil level to stabilize.

7. Contaminated or overheated oil may cause damage to transmission-hydraulic system components. Oil which is:

   • Milky or foamy may be contaminated with water. Change oil immediately.
   • Discolored or smells burned may have been overheated. See your John Deere dealer.
   
   

   Check hydraulic reservoir oil level using sight gauge located on right-hand side of gudgeon area. Examine oil in sight gauge for milky or foamy appearance.

   As tractor and hydraulic system temperature increases, oil level will rise in reservoir.

   Oil level in reservoir fluctuates depending upon volume of oil exchanged with an attached implement. If low oil level results in hydraulic pressure drop, a STOP engine light will come on.

8. Open hydraulic reservoir cap (A). Check for burned oil odor.

9. If reservoir oil level is between FULL COLD (B) and MIN COLD (C) marks, tractor can be used for normal operation. Volume difference between MIN COLD and FULL COLD marks is about 11.4 L (3 gal).

10. If reservoir oil level is below MIN COLD mark, add oil to hydraulic oil reservoir. Remove hydraulic oil reservoir cap and add oil, see Transmission-Hydraulic Oil in Service - Change section of this Operator’s Manual.
