COLD TEMPERATURE OPERATION
Before you start the engine and operate your
tractor during cold ambient temperatures, check the
following items:
● BATTERIES - Must have a full charge.
● FUEL - Must be clean and contain no water.
● ENGINE OIL - Must have the correct viscosity
for the ambient temperature range.
● TRANSMISSION HYDRAULIC FLUID - Must
have correct oil. Use McCormick HTX
transmission fluid.
● COOLING SYSTEM - Must have a minimum
of 33 percent and a maximum of 50 percent
low silicate ethylene glycol solution for
protection. This ratio will vary with different
market requirements.
● TYRES - If there is liquid in the tyres, the
tyres must have protection against freezing
temperatures below 0°C. See your dealer.
● STOPPING THE ENGINE - Permit the engine
temperature to decrease before stopping.
● CONDENSATION IN FUEL TANK - To
prevent condensation in the fuel tank and
water entering the fuel system, fill the fuel
tank after each operating day.
● FUEL FILTER - During cold ambient
temperatures, make sure you remove water
from the fuel filter each day or damage will
occur. Loosen the drain plug each day before
starting the engine. Tighten the drain plug
after the water has drained.
IMPORTANT: During cold ambient
temperatures never run the engine at low idle
speed for long periods of time. Never run the
engine for long periods of time when the
coolant temperature is below normal.
During cold ambient temperatures, the engine will
not heat to or keep the rated operating temperature
at slow engine speeds. Slow engine speeds in cold
temperatures can cause damage to the engine.
Use the following procedures to warm the engine
oil and transmission oil and to keep the correct
operating temperatures.
1. WARMING THE ENGINE AND
TRANSMISSION.
A. To heat the transmission oil, run the engine
at 1500 rpm for approximately five minutes.
2. KEEP ENGINE AT CORRECT OPERATING
TEMPERATURE.
A. When the engine is operating in cold
ambient temperatures without a load, keep
the engine warm as described below.
B. Run the engine at approximately 1500 rpm.
C. Put a cover in front of the grille to control
the amount of air going through the
radiator.
3. STOPPING THE ENGINE.
A. Run the engine at slow speed for a short
period of time. This will permit the engine
temperature to decrease gradually before
stopping the engine.
WARNING: To assist cold weather starting
DO NOT spray ether or gasoline into the air
induction manifold. To do so could cause
an explosion and injury.
