John Deere recommends using Plus-50 II engine oil for optimal performance and protection of the engine.
Start by checking the hydraulic fluid levels and filters. Inspect hoses and connections for leaks or damage. If the issue persists, consult the service manual for detailed diagnostics.
Regular maintenance includes checking and replacing air filters, changing engine oil and filters, inspecting belts and chains, and lubricating moving parts. Refer to the operator's manual for a complete schedule.
To calibrate the header, park the machine on a level surface, turn on the engine, and follow the calibration procedure outlined in the operator's manual, which usually involves setting the correct height and sensitivity settings.
Check the battery connections, ensure fuel is reaching the engine, and inspect the starter motor. If these steps do not resolve the issue, further electrical diagnostics may be necessary.
Turn off the engine and relieve pressure from the fuel system. Remove the old filter, install the new one, and ensure all connections are tight. Prime the system if necessary before starting the engine.
Symptoms include unusual noises, difficulty shifting gears, and slipping transmission. Regularly check transmission fluid levels and condition to prevent these issues.
The air filter should be checked regularly and replaced every 200 operating hours or more frequently in dusty conditions.
Drain fuel or add a stabilizer, change the oil and filter, clean the machine thoroughly, and store in a dry place. Disconnect the battery and check antifreeze levels.
Ensure regular maintenance such as air filter changes, proper tire inflation, and keeping the engine tuned. Avoid excessive idling and operate at optimal speeds.
