Common Issues with the John Deere 35D

1. Hydraulic System Concerns:
   • One of the most commonly reported issues with the 35D is related to its hydraulic system. This includes problems such as a slow response or a drop in hydraulic power. Regular checks and maintenance of hydraulic fluid levels, filters, and lines can help prevent these issues.
     
2. Engine Performance:
   • While the engine on the 35D is generally reliable, some users have reported issues with starting or performance under load. This could be caused by various factors, including fuel system blockages or problems with the air intake.
     
3. Electrical System Glitches:
   • Another area where owners have experienced trouble is with the electrical system. Issues such as faulty sensors, blown fuses, or problems with wiring connections can result in error codes, which can be difficult to diagnose. Regular inspection and timely repairs can avoid these issues from becoming major problems.
     
4. Undercarriage Wear:
   • The undercarriage, which includes components like tracks, rollers, and sprockets, can wear down over time, especially when used on rough terrain or under heavy loads. Regular inspection and replacement of worn-out parts are essential for maintaining the performance and safety of the excavator.
     

Maintenance Tips for the John Deere 35D

1. Hydraulic Maintenance:
   • Regularly check the hydraulic fluid levels and replace the fluid according to the manufacturer's recommendations. Inspect the hydraulic hoses for signs of wear or damage, and replace any worn parts to avoid system failures.
     
2. Routine Engine Care:
   • Keep the engine clean and well-maintained. Change the engine oil and replace the air filter regularly to ensure optimal performance. Also, make sure that the fuel system is free of debris and contaminants to avoid clogging.
     
3. Inspect Electrical Components:
   • Periodically inspect all electrical connections and wiring for corrosion or loose connections. Pay attention to any warning lights or error codes and address them promptly to prevent more serious issues down the road.
     
4. Track and Undercarriage Inspections:
   • Inspect the tracks, rollers, and sprockets regularly for signs of wear. Ensure that the tracks are properly tensioned, as both over-tightening and under-tightening can lead to premature wear. Clean the undercarriage frequently to prevent dirt and debris from causing damage.
     
5. Check Fluids and Filters:
   • Always ensure that the fluids (such as engine oil, hydraulic fluid, and coolant) are at the appropriate levels. Replacing filters as recommended by the manufacturer is vital to keeping the machine running efficiently.
     

Conclusion
The John Deere 35D is a versatile and reliable mini excavator that excels in various construction and excavation tasks. However, like any heavy equipment, it requires regular maintenance to keep it performing at its best. By understanding the common issues and following a proactive maintenance routine, you can extend the life of your 35D and ensure it continues to deliver dependable service on the job site. Whether you're a seasoned operator or a new owner, taking the time to care for your machine will pay off in the long run.
