PRE-HEATING THE ENGINE
Your tractor has a diesel engine. Before starting a

position for approximately 5 seconds. The glow
plugs heat the combustion chambers during this
time, and the engine will now be ready to start.
NOTE: When ambient temperature are colder, a
longer preheat time may be necessary. Even after
the cold start indicator light has gone out, the glow
plugs will continue to heat if the key is held in the
“HEAT position.
