Kubota M6800 Problems
Kubota’s M6800 tractor is said to have been reported to have several typical problems:
Fuel System problems:
Users have noticed that the M6800 may run roughly in hot temperatures, causing signs like a fluctuating RPM and an inability to respond to the throttle. Standard troubleshooting techniques include changing the fuel filter, clearing the water separator, and checking the fuel and injector pump for blockages or other issues. One person encountered a situation in which the tractor performed well initially but could not maintain its RPM, and suspicion was raised regarding the condition of the fuel pump.
Clutch problems:
Certain owners have had multiple clutch replacements in the short term. One owner reported that his M6800 went through seven clutches, which indicates possible problems with the clutch system, mainly if the tractor has been frequently used for loading work. This could be made worse by the tractor’s history of operation and maintenance procedures.
Hydraulic problems:
Problems in the hydraulic system can also be observed, particularly when the tractor has been warmed up. There have been reports of the lack of power for the steering and loader, which is often attributed to hydraulic fluid contamination. One user noticed that their hydraulic fluid had discolouration and needed replacement to restore function.
General Maintenance Problems:
Regular maintenance routines like fluid changes and filter replacements are essential to avoid problems. A few users have expressed displeasure with the quality of their equipment and suggested that despite regular maintenance, they faced severe issues.
These issues emphasize the importance of regularly maintaining your equipment and quick troubleshooting to ensure that the Kubota M6800 operates efficiently.
