To calibrate the header height, ensure the windrower is on a level surface. Access the calibration settings through the main menu on the control panel, select 'Header Calibration', and follow the on-screen instructions. Ensure all hydraulic connections are properly secured before starting.
It is recommended to perform daily checks for oil levels, hydraulic fluid, and tire pressure. Every 100 hours, inspect belts, blades, and filters. Comprehensive maintenance, including changing oils and hydraulic fluids, should be conducted every 500 hours or annually.
Check the battery connections and ensure they are tight and free of corrosion. Verify that the fuel level is adequate and that the fuel filter is not clogged. Inspect the starter motor and solenoid for any signs of damage.
Ensure the header is level and properly adjusted according to the field conditions. Check the condition of the knives and replace them if they are dull or damaged. Verify that the windrower speed and ground speed are appropriately matched for the crop type.
Maintain optimal tire pressure and regularly clean the air filters to ensure efficient combustion. Use the recommended engine oil and keep the blades sharp to reduce engine load. Avoid unnecessary idling and operate the machine at recommended speeds.
Use John Deere's recommended hydraulic fluid, which is typically specified in the operator's manual. It is important to use the correct fluid to ensure efficient operation and to prevent damage to the hydraulic system.
First, ensure the machine is turned off and securely parked. Raise the header to a comfortable working height and engage the safety locks. Remove the bolts securing the blade and replace with new blades, ensuring they are aligned correctly. Tighten all bolts securely.
Excessive vibration can be caused by imbalanced or damaged blades. Check all blades for wear or damage and replace them if necessary. Inspect the drive belts and pulleys for alignment and wear, adjusting or replacing as needed.
Before starting, ensure all guards and shields are in place and secure. Check that the brakes are functioning properly and inspect all lights and signals for functionality. Verify that all controls are in neutral and that no tools or debris are in the operating area.
Clean the machine thoroughly to remove dirt and crop residue. Drain fuel or add a stabilizer to prevent degradation. Lubricate all moving parts and cover the windrower to protect it from the elements. Store it in a dry, sheltered location.
