John Deere 590 Operator's Manual

To adjust the cutting height, locate the height adjustment lever on the machine. Adjust the lever to the desired height setting, ensuring that both sides are evenly set to maintain an even cut across the field.
Begin by checking the hydraulic fluid levels and inspecting for any leaks. Ensure all hydraulic connections are secure and that the filters are clean. If the problem persists, consult the service manual for further diagnostics.
Routine maintenance should be performed after every 100 hours of operation or at the start of each season. This includes checking fluid levels, inspecting belts and hoses, and lubricating moving parts.
To replace the drive belt, first, disconnect the power source. Then, remove the belt guards and release the tensioner. Carefully remove the old belt and install the new one, ensuring it is properly seated on all pulleys before re-tensioning and replacing the guards.
Ensure the engine is well-maintained by regularly changing the oil and filters. Keep the tires properly inflated and minimize idling times. Additionally, operate the windrower at optimal speeds as recommended in the user manual.
Check the battery connections and charge, inspect the fuel system for obstructions, and ensure the engine oil level is correct. If the problem continues, examine the starter motor and ignition switch for faults.
Clean the windrower thoroughly, change the oil and remove any remaining fuel. Lubricate all moving parts and store it in a dry, covered area. Disconnect the battery and inflate the tires to the recommended pressure for storage.
Regularly inspect the blades for wear and damage. Sharpen them as needed using a proper sharpening tool or replace them if they are beyond repair. Ensure the blades are balanced to avoid vibrations during operation.
Excessive vibration might be due to unbalanced blades or worn bearings. Check the blades for balance and replace them if necessary. Inspect the bearings for wear and replace them if they are damaged.
To check belt tension, press down on the belt midway between pulleys. There should be a slight give, but not too loose. Adjust the tensioner as needed to achieve the recommended tension specified in the user manual.
