ENGINE BLOCK HEATER
The engine block heater, 1, warms the engine
coolant to aid starting by reducing engine drag.
When used with the cold start system, the heater is
an effective starting aid in temperatures down to -29°
C (-20° F).
To operate the heater, plug the heater cord, 2, into a
suitable 115-volt circuit for at least four hours before
starting the tractor.
You can leave the heater in operation for periods
longer than four hours without damage, but
maximum starting ability is usually attained after the
coolant has been heated for four hours.
WARNING
To avoid shocks or other injuries, never use an
ungrounded or inadequate extension cord.
Always use a grounded 3-wire extension cord
with a 3-wire plug which is rated for at least a
15-ampere load, and protected by a suitable fuse
or circuit breaker.

OPTIONAL HYDRAULIC OIL SUMP

hydraulic oil at a warm temperature which aids
cold weather starting. The heater is installed
in the left side of the rear axle assembly. To
operate the heater, plug the heater cord, 1,
into a suitable 115-volt circuit.
WARNING
To avoid shocks or other injuries, never use an
ungrounded or inadequate extension cord.
Always use a grounded 3-wire extension cord
with a 3-wire plug which is rated for at least a
15-ampere load, and protected by a suitable fuse
