Maintenance and Service Details for John Deere D108
Check the engine oil every 50 hours of operation or at least once per season. Replace the oil filter and change the oil if it hasn’t been done in the last 100 hours. Always use SAE 10W-30 oil for the best performance in various temperatures.
The air filter must be cleaned or replaced every 100 hours. If operating in a dusty environment, clean it more frequently. Check for dirt or debris around the filter housing to prevent air restriction.
Inspect the spark plug every 100 hours of operation. Clean or replace it if it shows signs of wear, corrosion, or damage. The correct spark plug type is NGK BPR5ES, which ensures smooth engine performance.
Every 100 hours, inspect the mower deck for any build-up of grass and debris. Clean the deck using a brush or a blower to maintain the cutting efficiency. Ensure that the blades are sharp and balanced; replace them if they are dull or damaged.
Inspect the battery terminals every 50 hours to prevent corrosion. Clean and tighten the terminals as needed. If the battery is over a year old, check the charge regularly and replace it if necessary.
The transmission belt should be checked for wear and tension every 100 hours of operation. If it starts slipping or shows signs of damage, replace it immediately to avoid further mechanical issues.
For the wheels, ensure they are inflated to the recommended pressure of 14-17 psi for optimal performance. Check tire condition every 50 hours and replace them if the tread is worn out or the tires are damaged.
Regularly lubricate the mower’s chassis. Apply grease to the fittings every 25 hours of use to prevent excessive wear on moving parts and ensure smooth operation of the deck and steering components.
Ensure the fuel system is in good condition by checking for leaks and inspecting the fuel filter every 200 hours. Replace the filter as part of the routine maintenance schedule.
Keep the battery terminals and cables free from corrosion. If corrosion appears, clean the terminals with a mixture of baking soda and water. This helps maintain strong electrical contact and ensures reliable starting performance.
For proper lawn care, keep the mower deck height at the manufacturer’s recommended setting. Adjust the height depending on grass length, and always ensure that the wheels are set to the same height for uniform cutting.
