GENERAL MAINTENANCE

The long trouble-free life of your machine 
depends on the maintenance it receives. Set 
up a maintenance program for your 8400 to 
cover the following points:

Keep tractor and mowers clean.

Keep all moving parts properly 
lubricated (see LUBRICATION on 
page 23).

Keep all parts properly adjusted.

Inspect for loose, worn or damaged 
parts.

Keep shields in place at all times.

Keep tires properly inflated.

If your inspection reveals worn or damaged 
parts, replace these parts before operating 
machine or before actual breakdown occurs.

ASSEMBLY AND DISASSEMBLY

Use the illustrations in the Parts Manual as 
reference for disassembly and assembly of 
components. Always maintain relative 
position of parts when disassembling. Clean 
and lubricate individual parts and 
components as required.

BATTERY

1. Make certain the ignition switch is in the 

“off” position and the keys have been 
removed.

2. Refer to the Mower Specifications in this 

manual for battery specifications.

3. When the battery is being installed or 

removed, make sure that the positive 
and negative terminals do not come in 
contact with metal tractor parts at the 
same time, or severe damage may 
result.

4. Battery connections must be kept clean 

and tight at all times. Loose cables will 
cause eventual battery failure. Keep 
terminal covers in place.

5. Use soap and water to clean the battery 

as required. Care must be taken to 
prevent soap and water from getting 
inside battery.

6. Clean the terminal contact surfaces with 

a battery terminal brush or steel wool.

7. Tighten cables securely to battery 

terminals.

8. Apply a light coat of petroleum jelly or 

chassis lubricant to terminals and cable 
ends after assembly to prevent 
corrosion.

CHARGING A BATTERY

Charge battery only in a well-vented location, 
away from sparks or open flame.

1. Remove the battery from the tractor 

before charging.

2. Be sure charger is “off.“

3. Connect charger leads to battery. 

Connect the positive (+) connector from 
the charger to the positive battery 
terminal. Connect the negative (–) 
connector of the charger to the negative 

battery terminal.

4. Charge the battery using one of the 

methods shown below. Follow the 
manufacturer’s instructions on the 
charger.

MAINTENANCE

DANGER: To avoid possible 
serious bodily injury, before 
performing any adjustments, 
maintenance, or lubrication, place 
all controls in “neutral,” lower the 
mowers to the ground, engage 
parking brake, turn ignition switch 
off, and remove key.

DANGER: To avoid injury from hot, 
high-pressure oil, never disconnect 
hydraulic hoses with attachments in 
up position. Never rub hands across 
tubes, hoses, or fittings to check for 
leaks. Hydraulic fluid escaping 
under pressure can have sufficient 
force to penetrate the skin.

DANGER: Always wear protective 
glasses or goggles and protective 
clothing when working with 
batteries. Always connect the 
“ground” (black) cable last and 
remove it first whenever performing 
any maintenance. Batteries contain 
sulfuric acid and generate explosive 
mixtures of hydrogen and oxygen 
gases. Keep any device which may 
cause sparks or flames away from 
the battery to prevent explosions. 
Read and follow the battery 
manufacturer’s instructions on 
safety, maintenance, and installation 
procedures.

DANGER: To avoid possible injury, 
stand away from battery when 
charger is turned on. A damaged 
battery or a battery with an internal 
short could explode.
