Removing the Tractor from Storage

1. 

Check the engine oil.

Fully charge the battery, lower tractor 

off blocks, and inflate the tires to the 

recommended pressure.

3. 

Remove the spark plugs and wipe them off. 

Using the starter, crank the engine to pump 

the excess oil out of the spark plug holes. 

Replace the spark plugs and the ignition leads.

4. 

If drained before storing, fill the fuel tank 

with clean, fresh gasoline.

5. 

Check the level of the engine oil in the 

crankcase and the hydraulic reservoir tank.

6. 

Start the engine and allow to idle for a few 

minutes to ensure engine is operating properly.

7. 

Drive the tractor without a load to 

make certain all the tractor systems are 

functioning properly.

Service

Battery Removal

 WARNING

Battery posts, terminals and related accessories contain 
lead and lead compounds. Wash hands after handling.

The battery is located beneath the seat frame. To 

remove the battery:
1. 

Remove the hex washer screw (a) securing the 

battery hold-down bracket (b) to the frame. 

Then flip the battery hold-down bracket (b) 

up to free the battery. See Figure 4-7.

2. 

Remove the hex cap screw and sems nut 

securing the black negative battery lead 

to the negative battery post (marked NEG). 

Move the cable away from the negative 

battery post.

3. 

Remove the hex cap screw and sems nut 

securing the red positive battery lead to the 

positive battery post (marked POS).

4. 

Carefully lift the battery out of the tractor.

5. 

Install the battery by repeating the above 

steps in the reverse order. 

 WARNING

Always connect the positive lead to the battery before 
connecting the negative lead. This will prevent sparking 
or possible injury from an electrical short caused by 
contacting the tractor body with tools being used to 
connect the cables.

Charging the Battery

Test and, if necessary, recharge the battery after 

the tractor has been stored for a period of time.
• 

A voltmeter or load tester should read 

12.6 volts (DC) or higher across the battery 

terminals. See Figure 4-8.

• 

Charge the battery with a 12-volt battery 

charger at a MAXIMUM rate of 10 amps.

Servicing Electrical System

A fuse is installed to protect the tractor’s electrical 

system from damage caused by excessive 

amperage. Always use the same capacity fuse 

for replacement. If the electrical system does not 

function, check for a blown fuse.
If you have a recurring problem with blown fuses, 

have the tractor’s electrical system checked by your 

authorized service dealer.

Relays and Switches 

There are several safety switches in the electrical 

system. If a function of the safety interlock system 

described earlier is not functioning properly, have 

the electrical system checked by your authorized 

service dealer.

Parking Brake Adjustment

If the tractor does not come to a complete stop 

when the control levers are moved fully outward 

engaging the parking brake, or if the tractor’s rear 

wheels can roll with the parking brake engaged 

(and the hydrostatic relief valve open), the brake is 

in need of adjustment. See your authorized service 

dealer to have the brake adjusted.

Deck Removal

Remove the tractor deck from the tractor as follows:
1. 

Move the tractor to a level surface, 
disengage the PTO, stop the engine place 
the control levers in the neutral/parking 
brake engaged position.

2. 

Move the deck gauge wheels or rollers to 
their highest setting (lowest deck setting).

3. 

Remove the ‘V’ belt from the PTO pulley, 
located on the bottom of the engine, using one 
of the following two methods.

 WARNING

The muffler at the rear of the tractor may be extremely hot, 
and could cause serious burns. Use extreme caution when 
near the muffler. Allow the muffler to fully cool before 
removing the belt from the PTO pulley.

4. 

Releasing belt tension with the idler pulley:

a. 

Using the deck lift handle, raise the 

deck to the  position that provides 

the most horizontal run of the belt 

between the deck idler pulleys and 

the PTO pulley on the bottom of the 

engine. See Figure 4-9.

5. 

Rolling the belt off the PTO pulley:

a. 

Using the deck lift handle, raise the 

deck to the  position that provides 

the most horizontal run of the belt 

between the deck idler pulleys and 

the PTO pulley on the bottom of the 

engine.

b. 

Sitting behind the tractor facing 

forward, reach beneath the tractor 

to grasp the belt at the front of the 

PTO pulley.

 WARNING

Use caution to avoid pinching your fingers when rolling the
