Kubota B2920 Problems

Kubota B2920 is a great tractor. However, like any other vehicle, it has its share of problems. 

In this article, we will take a look at some of the most common Kubota B2920 problems and how to solve them.

Common Kubota B2920 Problems

Kubota B2920 Problems

1. Engine Losing Power

One of the most common problems with the Kubota B2920 tractor is engine power loss. If you’re experiencing engine power loss while operating your tractor, there are several potential causes. 

One possibility is faulty fuel injection nozzles. 

You’ll want to inspect the nozzles and replace them if necessary. Another possibility is dirty fuel hoses or lines. 

In this case, you’ll need to service the fuel lines and hoses. Yet another potential issue is a clogged air filter. 

If the air filter is indeed the problem, you’ll need to replace the air filter element. Finally, a worn cylinder head gasket can also cause engine power loss. 

If this is the issue, cylinder-head gasket replacement will be required. 

2. Tractor Engine Knocks

Another common problem with the Kubota B2920 tractor is engine knocking. This can be caused by a variety of factors, including low coolant temperature, insufficient engine oil, or wrong fuel injection pump timing. 

If the engine is not warmed up properly, it will likely knock. Make sure to fill the oil to the required level; if it’s too low, this could also cause knocking. 

Lastly, check the fuel injection pump timing and adjust it as necessary. 

If none of these fixes solve the problem, it is possible that the pistons are broken or worn and need to be replaced. 

Another possibility is that the connecting rod is misaligned or faulty; in this case, it will need to be changed or aligned.

3. Tractor Suddenly Shuts Off

One of the most common problems with the Kubota B2920 tractor is that it suddenly shuts off. 

This can be caused by a number of issues, including fuel injection pump timing that is not properly adjusted. 

If this is the case, it is important to set the fuel pump timing correctly. Another possible cause is a clogged fuel filter element. 

In this case, it is necessary to clean the filter or install a new filter element. Additionally, the engine may not be properly preheated. 

In this case, it is important to warm up the engine before use. 

4. Transmissions Making Noise

Most Kubota B2920 owners will eventually come across a problem with their transmission making noise. 

This is usually caused by worn or unadjusted speed control linkage. 

The best way to fix this problem is to repair or adjust the linkage. Another common problem with the Kubota B2920 is transmission overload. This can be caused by contaminated transmission fluid or a low fluid level. 

To fix this problem, you should add fluid to the correct level or fill the transmission with fresh fluid. If the relief valve is stuck, you should replace it. 

Finally, if there are worn or defective parts of the hydrostatic transmission, you should replace them after disassembly and inspection.

5. Hydraulic System Overheats

The Kubota B2920 is a versatile tractor that can be used for a variety of tasks, from ploughing to tilling to mowing. However, like all machinery, it is subject to occasional problems. One such problem is overheating of the hydraulic system. 

This can be caused by using the wrong type of hydraulic oil, contamination of the hydraulic fluid, or air in the system. 

In most cases, the problem can be resolved by replacing the hydraulic fluid or bleeding the air out of the system. 

However, if the main relief valve fails, replacement may be necessary.

6. Hitch Can’t Lift

Some owners are complaining that their tractor hitch can’t lift, resulting in reduced productivity. 

There are several possible causes for this problem, including a hydraulic pump malfunction, a faulty main relief valve, or a clogged hydraulic oil filter. 

In most cases, the problem can be quickly resolved by making a few simple repairs or adjustments. 

However, if the hitch continues to fail to lift, it may be necessary to replace one of the major components. 

Fortunately, Kubota offers a wide range of replacement parts and factory-trained technicians who can perform the necessary repairs.

7. 3 Point Hitch Lower Slowly

The three-point hitch on a Kubota B2920 tractor is used to raise and lower attachments such as a bush hog or plow. 

The hitch consists of a hydraulic cylinder, hydraulic spool valve, cross shaft and stabilizers. 

If your Kubota B2920-3 is having trouble lowering slowly, it could be due to a faulty hydraulic cylinder. You may be able to repair the cylinder, but it may be necessary to replace it. 

Another possibility is that the hydraulic spool valve is out of adjustment. 

This can usually be fixed with a simple adjustment. If the problem persists, it may be necessary to replace the hitch cross shaft. 

This part wears out over time and will need to be replaced eventually. Finally, if the three-point hitch is out of adjustment, this can also cause problems with lowering. 

Adjusting the hitch is usually a fairly simple process. 

However, if you are unsure how to do it, you should consult a manual or an experienced mechanic.

8. Hard Steering

One of the most common problems with the Kubota B2920 is hard steering, which can be caused by a number of different issues. 

First, there may be air in the hydraulic steering system, which can be remedied by bleeding the system. 

Second, the steering filter may be dirty, so it’s important to clean the filter element. Third, there may not be enough steering oil, so you’ll need to check the oil level and add steering oil as required. 

Fourth, the hydrostatic steering unit may have damage or wear, so you’ll need to repair or replace the steering unit. 

Fifth, the steering pump may have failed, so you’ll need to install a new steering pump. 

Finally, the steering pump control valve may be stuck or faulty, so you’ll need to service or change the control valve. 

9. Starter Turns Slowly

Kubota tractors are known for their strength and durability, but even the best machines need a little care from time to time. One common issue that can arise is a slow-turning starter. 

This can be caused by a number of factors, including a low battery voltage or corrosion on the battery terminals. 

If the battery voltage is low, the simplest solution is to charge the battery. However, if the battery runs down quickly, it may be necessary to service the charging system or change the battery altogether. 

Corroded battery terminals can also cause starter problems, so it’s important to check the cables and terminals regularly. In most cases, a simple cleaning will suffice. 

However, if the corrosion is extensive, it may be necessary to replace the terminals.
