When storing the tractor for extended periods, disconnect 

1. 

the negative battery cable. It is not necessary to remove 

the battery.
All batteries discharge during storage. Keep the exterior 

2. 

of the battery clean, especially the top. A dirty battery will 

discharge more rapidly.
The battery must be stored with a full charge. A discharged

charged battery will store longer in cold temperatures than hot.
Recharge the battery before returning to service. Although

the tractor may start, the engine charging system may not 

fully recharge the battery.

If your tractor is not going to be operated for an extended period 

of time (thirty days to approximately six months), the tractor should 

be prepared for storage. Store the tractor in a dry and protected 

location. If stored outside, cover the tractor (including the tires) to 

protect it from the elements. The procedures outlined below should 

be performed whenever the tractor is placed in storage.

2. 

To prevent gum deposits from forming inside 

a. 

the engine’s carburetor and causing possible 

malfunction of the engine, the fuel system must be 

either completely emptied, or the gasoline must be 

treated with a stabilizer to prevent deterioration.

Fuel left in the fuel tank deteriorates 

and will cause serious starting problems.

Using a fuel stabilizer:

b. 

Read the product manufacturer’s instructions 

• 

and recommendations.
Add to clean, fresh gasoline the correct 

• 

amount of stabilizer for the capacity 

(approximately 3 gallons) of the fuel system.

engine for 2-3 minutes to get stabilized fuel 

into the carburetor.

c. 

Prior to putting the tractor in storage, monitor 

• 

fuel consumption with the goal of running

in the carburetor has been exhausted.
Referring to the engine manual, drain the fuel 

• 

from the carburetor bowl. 

Clean the engine and the entire tractor thoroughly.

3. 

Fully charge the battery, then disconnect the negative 

4. 

cable at the battery to prevent possible discharge. 

Recharge the battery periodically when in storage. 
NOTE: Remove the battery if exposed to prolonged periods 

of sub-freezing temperatures. Store in a cool, dry location 

where temperatures are above freezing. 
Lubricate all lubrication points.

damage to electrical components, spindles, pulleys, 

bearings or the engine. The use of water will result in 

shortened life and reduce serviceability.
