To perform a routine maintenance check on the John Deere A400 Windrower, start by inspecting the engine oil level and quality, checking the air filter, assessing the condition of belts and hoses, and ensuring all safety features are operational. Regularly lubricate all moving parts and check tire pressure.
If the windrower is not starting, check the battery connections and charge, ensure the fuel tank is full, inspect the fuel filter, and examine the ignition switch. Additionally, check for any blown fuses and ensure the PTO is disengaged.
To improve cutting performance, regularly sharpen or replace blades, ensure the cutter bar is adjusted correctly, and maintain the correct ground speed according to crop conditions. Additionally, make sure the windrower is properly leveled.
If the windrower is overheating, check the coolant level and radiator for blockages. Ensure that the fan belt is in good condition and the fan is working properly. Clean any debris from the radiator and oil cooler.
Oil in the John Deere A400 Windrower should be changed every 100 hours of operation or annually, whichever comes first. Always use the recommended oil type and follow the manufacturer's guidelines.
To calibrate the header height on the A400 Windrower, ensure the machine is on a flat surface, engage the calibration mode from the control panel, and follow the on-screen prompts to set the desired header height. Consult the operator’s manual for detailed instructions.
To replace the hydraulic fluid, first park the windrower on level ground and turn off the engine. Drain the old fluid from the hydraulic reservoir and replace it with new fluid, ensuring the correct type is used. Check for leaks and proper fluid levels after replacement.
If unusual noises are heard, inspect the belts and pulleys for wear or damage, check all bearings for play, and ensure all fasteners are tight. Also, examine the cutter bar and blades for obstructions or damage.
Regularly test safety features by checking all switches and sensors, ensuring guards and shields are in place, and verifying that emergency stop functions are operational. Refer to the safety section of the operator’s manual for detailed procedures.
To prepare for long-term storage, clean the windrower thoroughly, drain fuel or use a stabilizer, change the oil, and lubricate all moving parts. Store in a dry, sheltered area and disconnect the battery to prevent discharge.
