4th gear ratio: 1:1.
These ratios contribute to the overall versatility and reliability of the machine, ensuring it performs optimally across a variety of operations.
To maintain smooth operation and avoid wear on the system, it is recommended to periodically check the transmission fluid levels and ensure they are within the optimal range. Regular servicing of the transmission will prolong its lifespan and maintain the performance of the John Deere G tractor.
Maintenance Requirements and Service Intervals

Perform routine oil changes every 100 hours of operation. Use high-quality engine oil recommended by John Deere for optimal performance.
Check the air filter at every 50-hour interval. Replace it if it shows signs of clogging or wear to maintain proper airflow and engine efficiency.
Inspect the cooling system after every 200 hours of use. Clean the radiator and check for any blockages to prevent overheating.
Grease the tractor’s moving parts every 25 hours to avoid friction-related wear. Apply grease to the joints, pins, and linkage points as specified in the user manual.
Replace the fuel filter every 500 hours to ensure proper fuel flow and prevent debris from damaging the fuel system.
Inspect the tires every 100 hours to check for wear and proper inflation. Uneven tire pressure can lead to poor handling and excessive wear.
Check the transmission fluid levels every 200 hours. Low fluid levels may cause the transmission to overheat and reduce its lifespan.
Ensure that the battery is clean and the terminals are free from corrosion. Inspect it at every 50-hour service interval to guarantee proper charging.
For the hydraulic system, check the fluid levels and replace the filter at every 400 hours. Contaminated fluid can cause poor system performance and component failure.
