Hydraulic Oil
WARNING! Never overfill the hydraulic units. 
Damage can occur if the oil level is not within the 
proper operating range.
NOTE: When adding hydraulic oil, do so in small quantities and 
recheck the oil level before adding more. It is important that you 
do not overfill the reservoir.
Battery Maintenance
The battery is filled with battery acid and then sealed at 
fill caps and check the level of the liquid electrolyte in the 
battery. If the level in any of the six cells has dropped below 
the bottom of the split ring inside the fill hole, refill the cell 
with distilled water.
terminal sealer, or coat the terminals with a thin coat of 
grease or petroleum jelly, to protect against corrosion.
Always keep the battery cables and terminals clean and 
free of corrosion.
Avoid tipping. Even a sealed battery will leak electrolyte 
when tipped.
WARNING! 
emit explosive gases. Use extreme caution when 
handling batteries. Keep batteries out of the reach 
of children.
Engine Coolant
Checking Engine Coolant Level
reservoir should be checked to ensure it is within the operating 
range. Engine coolant absorbs heat from the engine and 
transfers the heat to the air flowing through the radiator. If the 
coolant level becomes low, the engine may overheat and could 
cause severe damage to the engine.
Use a permanent type antifreeze containing corrosion and rust 
NOTE: Distilled water is recommended for the coolant solution 
IF your tap water has a high mineral content. Minerals cause 
efficiency will be greatly reduced over time and severe engine 
instructions for additional information on dilution procedures.
Check the coolant level when the engine is cold and the 
tractor is on a level surface.
Check the coolant level in the overflow reservoir on the 2. 
right side of the tractor.
cap from the reservoir and add coolant solution to the 
“FULL” mark. Refer to Fig. 6-2.
NOTE: The cooling system is a closed type. Normally, to prevent 
air from entering the system, the radiator cap should not be 
removed. 
If the overflow reservoir is empty, the radiator cap should be 
removed and the coolant level in the radiator checked before 
adding coolant to the reservoir. If necessary, first refill the system 
through the radiator filler neck as follows:
WARNING! It is dangerous to remove the radiator 
cap when the system is hot. Allow the system to cool 
before removing the radiator cap.
