to fly a long distance.

• Clear work area of bystanders.
• Wear eye protection when using compressed air for cleaning purposes.

• Reduce compressed air pressure to 210 kPa (30 psi)

IMPORTANT: Avoid damage! An obstructed air intake screen can

cause engine damage due to overheating. Keep air intake screen

and other external surfaces of the engine, including cooling fins,

clean at all times to allow adequate air intake.

How to Change the Oil and Filter on a John Deere Tractor 100 Series Engine

 

• IMPORTANT: Avoid damage! Change the oil more often if the
• vehicle is used in extreme conditions:
• Extremely dusty conditions.
• Frequent slow or low-speed operation.
• Frequent short trips.

03.2024 John Deere Service Advisor 5.3.235 AG/CF Diagnostic Software

1. Run engine to warm oil.
2. Park machine safely. (See Parking Safely in the SAFETY section.)
3. Lift hood.

Picture Note: Twin cylinder engine shown.

4  Put drain pan under drain valve (A).

5  Rotate and remove drain cap (B) and drain oil into oil drain pan. Allow

oil to drain completely.

6 Remove dipstick (C).

7 Replace oil filter (D), if equipped.

a.Wipe dirt from around oil filter.

b.Place a drain pan or funnel under filter tray.

c.Remove old filter and filter gasket and dispose of properly. Wipe up

any spilled oil.

d.Put a light coat of fresh, clean oil on the new filter gasket.

e.Install replacement oil filter by turning oil filter to the right (clockwise)

until the rubber gasket contacts filter base. Tighten filter an additional

one-half turn.

8 Install drain cap

IMPORTANT: Avoid damage! Do not overfill. Overfilling can cause

smoking, hard starting, fouling of spark plug, and oil saturation of

air filter.

9 Add oil no higher than FULL mark on dipstick. Use approximately the

amount of oil listed in the Specifications section. Do not overfill.

10 Install dipstick.

11 Start and run engine at idle to check for leaks. Stop engine. Fix any

leaks before operating.

12 Check oil level. Add oil if necessary

How to Check Engine Fluid Levels (John Deere Tractor 100 Series Engine Maintenance Procedure 1)

 Engine Oil 

 

John Deere Service Advisor Electronic Data Link EDL2 Diagnostic Adapter High Quality

 

Use oil viscosity based on the expected air temperature range during the 

 

period between oil changes.

 

    

The following John Deere oils are preferred: 

 

• TURF-GARD™ 

 

• PLUS- 4™ 

 

 

Other oils may be used if above John Deere oils are not available, 

 

provided they meet the following specification: 

 

• API Service Classification SJ or higher

Checking Engine Oil Level

 

IMPORTANT: Avoid damage! Failure to check the oil level

regularly could lead to serious engine problems if oil level is out

of the operating range:

• Check oil level before operating.

• Check oil level when the engine is cold and not running.

• Keep oil level between the dipstick marks.

• Shut off engine before adding oil.

 

NOTE: Check oil twice a day if you run engine over 4 hours in a day.

Make sure engine is cold when checking engine oil level. 

 

  

 

1. Park machine safely. (See Parking Safely in the SAFETY section.) 

 

2. Lift hood. 

 

3. Clean area around dipstick to prevent debris from falling into crankcase

 

  

 

 

Picture Note: Twin cylinder engine shown. 

  

4. Remove dipstick (A). Wipe with clean cloth. 

 

5. Install and tighten dipstick.

 

6. Remove dipstick. 

 

7. Check oil level on dipstick. Oil must be between ADD and FULL marks. 

 

8. If oil level is low, add oil to bring oil level no higher than FULL mark on 

 

dipstick. Do not overfill. 

 

9. Install and tighten dipstick. Lower hood.
