Kubota B2920 Problems
Owners of the Kubota B2920 tractor have reported a few common issues, primarily concerning starting difficulties and driveline problems.
Starting Problems
- Intermittent Starting Failure: Some users have faced inconsistent starting issues. One example is a situation where the tractor wouldn’t start even though the dashboard lights were functioning normally. Replacing the ignition switch didn’t resolve the problem, leading to suspicions about the battery or wiring connections. A flickering battery light often serves as a clue to whether the tractor will start.
- Potential Causes: These starting issues are typically linked to faulty ignition switches, battery problems, or wiring issues. It’s not uncommon for the tractor to start fine intermittently before failing again, suggesting an intermittent electrical fault rather than a constant mechanical issue.
Driveline Problems
- Drive Issues: Another frequent problem involves the tractor’s ability to move in two-wheel drive (2WD). If the tractor fails to move, it could point to a breakage in the main driveline, particularly in the rear drive components. Such issues often require a detailed inspection of the drivetrain to diagnose and fix the problem.
General Considerations While the Kubota B2920 is generally praised for its performance and reliability, potential buyers should be aware of these common issues. Regular maintenance and timely attention to electrical and driveline concerns are crucial to keep the tractor running smoothly.
Kubota B2920 Review
The Kubota B2920 is generally well-regarded for its performance and versatility, though some users have highlighted specific pros and cons based on their experiences.
Positive Aspects
- Ease of Use: Many users find the B2920 to be user-friendly, with intuitive controls that make it accessible for both beginners and seasoned operators. This enhances the overall operating experience.
- Powerful Engine: The tractor features a 29 horsepower, three-cylinder diesel engine that delivers strong performance for various tasks like mowing, tilling, and light construction work. It’s frequently praised for handling demanding jobs effectively.
- Compact Size: Its compact dimensions make it a good fit for residential properties and smaller farms. It offers excellent maneuverability in tight spaces while still being capable of performing heavy-duty tasks.
Negative Aspects
- Mower Attachment Issues: Some users have reported problems with the mower hanger pin holes not aligning properly, which can make attaching mowing implements a hassle. This issue can be particularly frustrating for those who rely on the tractor for mowing.
- Driveline Concerns: A few owners have expressed concerns about the driveline, especially when using the tractor on inclines or with heavy loads. Reports of creaking noises during operation may suggest potential issues with the transmission or driveline components.
- Starting Problems: Intermittent starting issues have also been noted, where the tractor may fail to start despite having a new battery and ignition switch. This inconsistency can be a significant inconvenience and cause frustration.
Conclusion
In summary, the Kubota B2920 is praised for its reliability and performance in a compact form, making it a popular choice for a range of agricultural and landscaping tasks.

Regular maintenance and attention to these concerns can help ensure a positive ownership experience.
