fuels, lubricants & general info


Specifications based on the 1987 model year.
Specifications may be different on newer or older models.
 
FUEL
IMPORTANT: DO NOT mix oil with gasoline.

Unleaded fuel is recommended. Regular leaded gasoline with an anti-knock index of 87 or higher may be used. Avoid switching from unleaded to regular gasoline to prevent engine damage.

Use of gasohol is acceptable as long as the ethyl alcohol blend does not exceed 10 per cent. Unleaded gasohol is preferred over leaded gasohol.

Fuel tank capacity is 3-1/2 gal (13.25 L).

Fill fuel tank at end of each day's operation.
     
ENGINE OIL

Depending upon the expected air temperature range during the drain interval, use oil viscosity shown below.

John Deere TORQ-GUARD SUPREME engine oil is recommended. If other oils are used, they must be premium quality engine oils meeting performance requirements of:

-API Service Classification SD, SE, SE/CC or SF.

Quality engine oils are blended, so additives are neither required nor recommended.

Some increase in oil consumption may be expected when SAE 5w-20 Oil is used. Check oil level frequently.

IMPORTANT
The Kohler engine owners manual recommends using 30 weight oil. SAE 10w-30 oil is not recommended for temperatures above 32 degree F. It states that using this oil substantially increases oil consumption and combustion chamber deposits.


Tractor requires 2 qts. (1.9 L) of oil.
     
GENERAL PURPOSE GREASE
John Deere Multi-Purpose Grease is recommended. If other greases are used, use:

-SAE Multi-Purpose Grease.
-SAE Multi-Purpose Grease containing 3 to 5 percent molybdenum disulfide.

At temperatures below -22 degrees F (-30 degrees C), use arctic greases such as those meeting Military Specification MIL-G-10924C.
     
TRANSAXLE OIL AND HYDRAULIC LIFT OIL

Use SAE 90 oil meeting Service Classification GL-5 requirements in transaxle.
Requires 3-1/2 pt (1.7 L) SAE 90 oil (GL-5).

Use John Deere All-Weather Hydrostatic Fluid or an equivalent type F automatic transmission oil in hydraulic lift (optional equipment).

Personal Note...
As you may have found out, trying to find SAE 90 oil is difficult. The local John Deere dealership (near me) looked at me very strange when I had asked for Transaxle Oil. It seems that the no longer carry it, (they use to because I still have the original John Deere container that has Transaxle Oil written on it) so instead I found on a few websites that another type of oil which can be used is SAE 80w-90. As long as the last number matches and its (GL-5) compliant then its safe to use. One benefit of using this weight is that it remains more fluid in colder weather.
