• Strainer transmission
• The hydraulic line
• The freeze plug

Apart from this, we can arrange other common problems with Kubota tractors into four categories, as seen below:

B7100 Engine Problems

The most serious Kubota B7100 problems are perhaps with the engine. Without the engine working properly, it’s hard to get your machine running smoothly.

Here we have the most common problems, causes, and how to fix them.

• The engine doesn’t start or start hard. It can be due to clogged fuel filters, the air inside the fuel system, air bleeding, or faulty fuel injection. You can fix it by servicing the filters, checking the injection nozzles and replacing them where necessary, and repairing the fuel pumps.
• Sudden stop of the engine. If you are in the middle of an operation and the engine stops suddenly, it could mean an incorrect setup of fuel injection pumping. This issue can be handled by adjusting the pump, checking clogged filters, warming up the engine, and replacing the filters.
• Overheating. If the engine overheating? Ensure the radiator is clean, replace the radiator cap, check the engine coolant, check the fan belt, and check the oil and service as required.
• Abnormal noise in the engine. The coolant temperature could be too low. You can warm up the engine first. It could also mean fuel lines are restricted, have them cleaned. Proper maintenance of air filters or replacing a faulty head gasket should also resolve this issue.

Other engine problems include turning off when in idle mode, losing diesel power, and insufficient oil pressure. Suggested solutions for these B7100 problems include:

• Setting the low idle speed properly.
• Inspecting and replacing fuel injection nozzles.
• Adding oil to the crankcase.

Transmission Issues

If the engine is ok, you may have to check the transmission. Here are some of the common issues and how to resolve them:

• Unwanted noise in the transmission. It is a common B7100 problem caused by improver backlash and worn-out gears. You may fix the issue if you get new gears and correct the backlash. It could also be due to faulty back spines. Replace the shaft. If the lift fork is damaged, the transmission is missing enough fluid, or the bearings are broken, it will also cause a similar problem. Your appropriate methods to clean the fluid or change it.
• Hard to shift the gears. It could be an issue with a faulty gear shift. Try lubricating and replacing the linkage in the shift. Check the clutch adjustment and ensure they are working properly, or replace them whenever needed.
• Oil leaks in the transmission. Leaking oil is another common problem on older Kubota tractors. Broken seals and engine gaskets could cause it. It could be from too much fluid transmission. You can resolve this by changing the broken seals and draining the excess fuel.

If the transmission has an issue, your Kubota B7100 will not run smoothly.

It’s recommended that you switch off all operations and wait until you have fixed the issues before resuming any operation.

Kubota B7100 Starting Problems

You may wake up and discover that your tractor is not starting. You try turning the ignition several times, but it won’t budge.

There are several reasons for this problem:

• Low battery. A low battery problem in your Kubota B7100 will cause starting problems. Charge your battery to give it enough energy. It could be that the terminals are corroded and are not supplying the current effectively, clean them. If your battery is too old, get a new one, and you should perform well.
• Fuel problems. If your tractor has insufficient fuel, you will encounter starting problems. Or perhaps a blockage prevents the fuel from flowing effectively to the engine. Ensure you use clean fuel and clean the fuel injection system/ pipes. Using good quality fuel is always recommended.
• The starter refuses to crank. A low or drained battery will not have enough CA to crank the starter. Check and fix this issue by charging or replacing the battery or resetting the cable connected properly.

Give your tractor enough juice and power to start. Service your engine whenever possible, keeping it clean to prevent starting issues.

Kubota B7100 Steering

Is your tractor showing some issues in the steering? You can have them fixed easily to keep enjoying the powerful performance of these tractors.

Common issues include:

• Too much play on the steering wheel. Causes include worn steering bearings, faulty linkage, and worn gear in the steering. You can fix this by replacing any faulty components and tightening anything loose.
• Difficulty steering. It could be that the steering column is struck or you have worn out parts. Fix this by checking these faulty parts and oiling or replacing them as required.
• Unstable front wheel. If the front wheel wanders left or right, it could indicate worn or loose linkage. Uneven tire pressure is another common cause, which is easily fixed by adjusting the pressure.

If your Kubota tractor is showing such issues in the steering, it’s proper to have it checked as soon as possible.

The experience you will get without fixing it is far from pleasing. If you can fix them yourself, get an expert to check them.
