Run the Engine

IMPORTANT: Do not start engine with throttle pushed completely forward.

Avoid excessive engine idling (more than 5 minutes). Prolonged idling may cause engine coolant temperature to fall below normal range. Prolonged idling causes crankcase oil dilution, due to incomplete fuel combustion, and permits formation of gummy deposits on valves, pistons, and piston rings. It promotes rapid accumulation of engine sludge and unburned fuel in exhaust system.

Operate engine between 1500—2100 rpm. Do not operate engine constantly below 1500 rpm during heavy draft usage or when tractor is under full PTO load.

For maximum tractor performance:

• Ensure that tractor is correctly ballasted (see Performance Ballasting section of this Operator’s Manual).
• For transmission information , see Operate the e18™ Powershift Transmission section of this Operator’s Manual.

If engine stalls, start immediately to provide lubrication to critical engine parts.

Allow engine to idle for 20 seconds before turning key switch to OFF position.

Contact your John Deere™ dealer if any symptoms that may be early signs of engine problems are detected:

• Sudden drop in oil pressure
• Abnormal coolant temperatures
• Unusual noise or vibration
• Sudden loss of power
• Excessive fuel consumption
• Excessive oil consumption
