Cooling system
The tractor engine must operate at the correct tempera-
ture to obtain maximum efîš¿ciency and service life. This
is dependent on the cooling system.
Always îš¿ll the system with a 50/50 solution of ethylene
glycol antifreeze and water.
Checking the coolant level
WARNING
Burn hazard!
Hot coolant can spray and scald if you remove the radiator or deaeration tank cap while the system
is hot. To remove the cap: allow the system to cool, turn the cap to the îš¿rst notch, and wait for all
pressure to release. Remove the cap only after all pressure has released.
Failure to comply could result in death or serious injury.

NOTE: Check the coolant level daily or after every 10 hours
of operation. The engine should be cold when coolant level
is checked.
1. Visually inspect the coolant level in the coolant recov-
ery reservoir (1) the coolant level should be between
the "LOW" and "HIGH" lines located on the side of the
reservoir.
2. If the coolant level is not between the "LOW" and
"HIGH" lines, add a water/antifreeze solution as neces-
sary. The cooling system already contains antifreeze,
add only antifreeze solution of the correct water/an-
tifreeze mixture. Pure water will dilute the solution and
weaken its protection.
3. Keep the radiator îš¿ns clear of chaff or dirt to allow free
air movement.
