Common Kubota L4701 Problems (And How to Solve Them)
1. Hydraulic System Issues
One of the most reported problems with the Kubota L4701 revolves around its hydraulic system. Users often notice a lack of lifting power, slow response times, or leaking hydraulic fluid.
Symptoms:
- Loader struggles to lift heavy loads.
- Hydraulics operate slower than usual.
- Visible fluid leaks near hydraulic lines or connections.
Causes and Fixes:
- Low Hydraulic Fluid Levels:
Check the hydraulic fluid reservoir and top it off if necessary. Use the manufacturer-recommended hydraulic fluid for optimal performance. - Worn Seals or Hoses:
Inspect the hydraulic lines and seals for signs of wear or damage. Replace any worn-out parts promptly to prevent leaks. - Clogged Hydraulic Filter:
A clogged filter can restrict fluid flow. Replace the filter according to your Kubota L4701 maintenance schedule.
Regular maintenance and inspections can help prevent hydraulic issues from escalating. Always follow the owner’s manual for proper care and use.
2. Engine Performance Problems
The Kubota L4701 is equipped with a powerful engine, but it’s not immune to occasional performance hiccups. These issues can affect productivity and fuel efficiency.

- Excessive smoke from the exhaust.
Causes and Fixes:
- Dirty Fuel Filter:
Replace the fuel filter if it’s clogged with debris or sediment. Clean fuel lines as needed to ensure proper flow. - Bad Diesel Fuel:
Contaminated or old diesel fuel can cause starting issues. Drain the tank and refill it with fresh, high-quality diesel. - Air Filter Blockages:
A dirty air filter restricts airflow to the engine. Inspect and clean or replace the filter regularly to maintain performance.
If these fixes don’t resolve the problem, consult a qualified technician to perform a more in-depth diagnostic.
