We’ll also provide some tips on how to avoid these issues in the future.
Whether you’re considering buying a B7500 or you’re already an owner, this is information you won’t want to miss!
Kubota B7500 Problems
1. Bogs Down
One common issue is that the tractor bogs down after running for a while. This can be caused by several factors, including too much grass in the mower deck, condensation in the fuel tank, or an accumulation of algae in the fuel line.
If you think your tractor is bogging down due to too much grass, try shutting off the PTO and raising the mower deck.
This will reduce the amount of strain on the engine and may help to solve the problem.
If you suspect condensation or algae growth is to blame, draining the fuel tank and changing the filter should do the trick. Lastly, make sure to check the air filter for any signs of a mice nest.
A clogged air filter can also cause bogging down issues.
2. Tractor Overheats
One problem that Kubota B7500 tractor owners may experience is overheating, especially when using the belly mower.
This is typically caused by the tall grass deflecting air flow away from the radiator, preventing it from properly cooling the engine.
Kubota recommends solving this problem by installing a deflector kit, which includes a metal screen that mounts onto the front of the radiator and helps to redirect airflow.
Another potential solution is to simply lower the deck on the mower, as this will allow air to flow more freely around the radiator.
However, if neither of these solutions works, it is possible that the exhaust pipe is blocked or damaged, causing hot exhaust gases to be redirected towards the radiator.
In this case, it is necessary to have the exhaust pipe repaired or replaced.
3. Loader not Going Down
One of the most popular attachments for this tractor is the LA272 loader, which can be used for everything from shovelling snow to loading hay bales.
However, some users have reported problems with the loader, specifically that it does not seem to want to go down.
The control lever will not make the bucket drop unless it is pushed all the way up into float position.
This can be a major problem, as it can make it difficult to perform some tasks.
However, there are some possible solutions. One is to take the loader valve assembly off and remove the two cup/caps at the bottom that cover the ends of the pistons.
Another is to check the spring and see if it needs to be replaced.
4. Transmission Problem
Many Kubota B7500 owners have reported transmission problems, including excessive noise and difficulty shifting gears.
In most cases, these problems can be traced to a build-up of metal shavings in the hydraulic fluid.
This can be caused by a variety of factors, including wear and tear on the transmission components or the use of non-approved fluids. In some cases, flushing the system and replacing the fluid may resolve the issue.
However, if the problem persists, it is likely that the transmission will need to be replaced.
Owners should be aware that this is a costly repair and may not be covered by their warranty.
5. Hitch not Lifting
Another common issue with the B7500 is that the hitch may stop lifting on one side.
This can be caused by a number of factors, but the most likely cause is a blown seal.
When this happens, it is necessary to open up the machine and replace the seal.
Thankfully, this is a relatively simple repair that can be easily completed by anyone with basic mechanical skills.
However, if you are unsure of how to do this, it is always best to consult with a qualified technician.
6. Losing Power
Another problem owners may experience is problems with the tractor struggling to run.
This can be due to a number of issues, such as overheating, clogged fuel filters, or a stuck thermostat.
These problems can usually be remedied with some basic troubleshooting.
For example, owners can try loosening the cap on the fuel tank when the problem occurs, or they can check the vent on the tank to make sure it is working properly.
7. Throttling Down
Kubota B7500 owners may experience problems with the engine throttling down or shutting off completely after only a few seconds of operation.
This can be caused by a dirty or clogged air filter, low fluid levels, or a lack of fuel.
If the engine starts right back up and only runs for a few seconds before shutting down again, it is likely a fuel pump problem.
Dropping the fuel filter and making sure it is full of fuel should resolve the issue. If not, it may be necessary to replace the fuel pump.
8. Steering Problem
One common issue that owners of this model often encounter is steering problems. These can be caused by a number of issues, including damage to the steering gear or steering shaft, wear and tear on the ball joint, or low tire pressure.
Fortunately, there are a few simple steps that can be taken to diagnose and fix these problems.
First, check the tire pressure with a pressure gauge to make sure that it meets the manufacturer’s specifications. If not, add or release air until it does.
Next, check the level of steering fluid and top it off if necessary. Finally, take the tractor for a test drive to see if the problem has been resolved.
If not, consult your owner’s manual or contact a qualified repair technician for further assistance.
9. Not Starting
Sometimes these tractors won’t start. There are a number of potential causes for this issue, but the most likely culprits are a loose or corroded battery connection, stale or improper fuel levels, or a blown fuse.
In some cases, the problem may be simply that it’s too cold for the engine to combust a mixture of air and fuel.
To troubleshoot this problem, check the transmission gear shift lever and the engine throttle lever. If they’re in the correct position, refill the fuel levels and check the air intake filter or fuel filter.
If any fuses are blown, replace them. If none of these solutions solve the problem, it’s possible that the shutoff valve is not allowing fuel to reach the cylinder.
In any case, it’s best to consult a Kubota dealer or qualified technician before attempting to make any repairs.
