Using Auxiliary Heaters

causym CAUTION: To avoid shock or hazardous operation, always use a three wire heavy duty electrical cord (minimum gauge 10 AWG and no longer than 7.6 m [25 ft]) equipped with three connectors. If a two to three contact adapter is used at the wall receptacle, always connect green wire to a good ground.

Before connecting heater to power source, be sure that the element is immersed in coolant. NEVER energize heater in air. Doing so can cause element sheath to burst causing personal injury.

Optional auxiliary heaters available from your John Deere dealer:

  • Engine Block (1000 W)
  • Transmission-Hydraulic Oil (200 W) 1
  • Hydraulic Charge Pump (200 W) 1

The 1000-watt, 110-volt coolant heater (A) is located on side of engine. By warming engine coolant the heater reduces oil drag, eases starting and shortens warm up time.

Connect heater(s) and ground fault interrupter (B) to a ground fault protected 110-volt electrical outlet.

IMPORTANT: Ground fault interrupter (B) on tractor protects tractor only and does not protect electrical wiring supplying power to tractor. Test all ground fault interrupters before each use.
