Kubota tractors are one of the best-known compact tractor brands in the market. Kubota produces an array of high-quality compact and subcompact tractors.
They are among the most reliable and efficient diesel engines on the market. Kubota is also recognized for its effectiveness and its, lifespan and sturdiness.
However, not all Kubota models are flawless and effective. Some of them have so many issues that you will not know which one to solve first.
Also, solving them can be very expensive. The warranty may cover some problems, but it does not cover all issues. So, it is better if you just avoid buying them at all.
Generally, transmission problems, engine problems, not starting, overheating, stalling etc., are very common with Kubota tractors. More specifically, Kubota tractor users have complained about countless problems with the models below: Kubota B3350, Kubota 1025R, Kubota L4701, and Kubota BX2380.
Here are the 5 Kubota Models you should avoid to have smooth tractor ussing experience:
1. Kubota B3350
All the Kubota B3350 users have complained that this model has regeneration problems. This mainly was caused by a problem with the DPF or the regeneration mechanism. Even after several repairs, it continues to fail. The DPF (Diesel Particulate Filter) regenerates far too often. It must also be parked.
Passive regeneration allows the DPF to empty itself, whereas active regeneration does not. In the case of shorter excursions, active regeneration occurs. This can lead to clogs. To empty it, you might need to travel for another 15 minutes at 40 mph.
Driving short distances and failing sensors are responsible for this problem, only found in the B3350 model. Kubota has yet to provide an effective remedy, despite the passage of time.
Also, the Kubota B3350’s engine has a hard time starting in the winter because the ECM is suitable for warm weather.
And when you do not use the Kubota B3350 for a week, it will start having problems with its spark plugs and batteries. And neither do you need to use a tractor every week nor can you keep playing for the fixes week after week.
Also, the Kubota B3350 does not cover the warranty because of all its problems. Thus, it is better if you avoid this model.
2. Kubota 1025R
Users have complained about the engine sputtering, spitting, and white smoke coming out with the Kubota 1025R model. And after all these problems keep on happening repeatedly, the engine shuts down completely. This issue occurs even when there is enough fuel.
Users also informed on forums and other platforms that they checked the fuel and air filters but found no problem, but still, the problems keep on occurring.
However, the issues get resolved when you let them idle for an hour or two, but that is a waste of fuel. So, it is better if you avoid the Kubota 1025R completely.
3. Kubota L4701
Kubota L4701 has frequent problems like- faulty fuel pumps, diesel not rotating, engine losing power, too much oil in the engine, faulty clutch, trouble with shifting, steering wheel spinning without resistance, improper valve adjustments, clutch failure etc.
Most of the problems are resolvable by replacing the faulty compartments and equipment, but if this happens frequently, it will cost you a lot. So, it is better to avoid the Kubota L4701 model completely.
A few users have repeatedly complained about the hydraulics of the FEL with their Kubota L4701 but have gotten no response from the Kubota company even though there was warranty time. This is very unexpected behavior from the company.
4. Kubota BH92 Backhoe
Kubota BH92 Backhoe has problems like- spring-loaded tensioners breaking loose, hydraulic leaks and a few other mild problems like clogged and blocked fuel pump frequently. The major problem with it is that the spring-loaded tension can break and cause major accidents for the user.
One of the users also complained about the spring-loaded tensioner breaking without warning; the parts had jumped into his eye and forehead, so he needed immediate surgery.
However, users also reported that when they write to Kubota’s company about their problems, Kubota remains unresponsive even though warranty time is left. So, it is better not to buy the Kubota BH92 model and avoid unwanted situations for your good.
5. Kubota BX2380
Kubota BX2380 tractors have repeatedly complained about problems like- janky switches, electrical connections for the third function part being low in quality, connector pieces not tied up securely, throttle lever keeps slipping etc.
The problems are quite complicated, and it will take a lot of time and expense to fix them, especially when they keep happening repeatedly.
According to some users of the Kubota BX2380, when they try to pull each side’s pins out to lay the foldable ROPS down, it is quite easy.
However, the issue emerges when they fold the ROPS back up and fail to align the pins. But when the users run the tractor with ROPS up, only one side’s pin lines up correctly. Although this is not a serious technical issue, it is disappointing for a tractor in the mid to high price category.
