When dealing with Kubota b7100 issues, you won’t find much difficulty. This can be very smooth if you are experienced in maintaining and caring for compact utility tractors. However, you should not worry if you do not have such experience, as you can always seek professional help.

1. Starting difficulty

The engine of the Kubota b7100 is pretty versatile, so it should run fast and smoothly. When you experience difficulty starting this powerful engine, it could be a problem with the fuel components. But first of all, you will have to ensure the presence of enough and proper fuel. Check the tank levels and ensure you’re using the correct diesel fuel.

The cleanliness of the fuel filter is necessary for the proper starting of the engine. Also, you will have to check the battery. A dead battery won’t allow the engine to start. So, you can either charge it or replace it in the case of internal battery damage.

2. Successful start followed by stalling

If the engine starts successfully but then stalls right away, this could be a sign to check the air and fuel filters. This can mean the clogs block the engine’s proper air and fuel distribution. So, you should get new filters and install them properly.

Also, it could be a sign that the fuel injection pump has become defective. In this case, your Kubota b7100 will stall and idle roughly too. So, you will need another pump. Remember that constantly cleaning the fuel injector can help you easily avoid problems.

3. Strange engine noises

The Kubota b7100 makes a bit of noise when it starts, but it is tolerable. However, this versatile diesel engine tends to be noisy by nature. However, the presence of any usual noises should get your attention.

Such noises can vary between knocking, cranking, and whining. In the event of such sounds, you will need to check the oil tank, as the oil levels could be lower than required. So, you can add more oil till the levels are normal again.

Another vital component to check is the coolant. This component is responsible for driving heat away from the diesel engine. So, if the coolant runs low, the engine will get overheated. Then, parts of the machine, such as the cylinder or pistons, could get damaged. Typically, all of this won’t go without making noise.

Getting the coolant temperature back to normal requires giving the engine a chance to warm up. It is also essential to replace damaged parts, such as the pistons. While you are at it, it won’t be wrong to check out the fuel injector, as it could have incorrect settings. The correct setting of this pump is critical for popper fuel combustion, which will keep your engine quiet.

4. Poor battery performance

If you plan to store your Kubota b7100 during the winteryou should not be surprised if the battery gets weak. The battery will lose its charge if stored for a long time. You can start making things work again by giving them a recharge.

However, this might not be the ultimate solution. The battery could have such severely corroded terminals that it won’t function properly again. In this case, you will have to get another one.

5. The wheel is difficult to steer

Riding the Kubota b7100 should be smooth without any steering difficulties, but this issue happens with various tractors, including the John Deere 2010. When a problem occurs, you should inspect the hydraulic fluid. It could be at low levels, which stand behind the stubborn wheel. So, you can refill the oil to adequate levels.

Another cause of this problem could be wear and tear on the front axle. This might require professional intervention from a technician. Also, you should thoroughly inspect the steering box assembly to find any defective replaceable components.

6. Difficulty shifting the transmission

This is not considered one of the exclusive Kubota b7100 problems. Transmission issues can be found in the John Deere 110 TLB and the Cub Cadet Challenger 750. This results in difficulty in shifting the gear to the desired position. It would be best if you first considered a lack of proper lubrication in gear parts. In this case, you will need to increase the transmission fluid levels.

Also, worn, bent, or defective gear parts, including the shift linkage, can lead to stubborn shifting. You can change these parts, and you will witness improvements. Also, inspecting the clutch is essential to diagnose the real issue with the gearbox.  

7. Hydraulic fluid problems

Hydraulic fluid or oil is a significant component for properly operating your Kubota b7100. When the levels of this fluid decrease, the hydraulic lift won’t function properly. No need to mention that the overall hydraulic system will overheat. In this case, the routine maintenance procedures are similar to what you would do when treating an overheating engine.

So basically, you will have to look at the hydraulic oil filter. It could be clogged due to fluid deposits or debris build-up that passes with the oil. You can purchase a new filter and ensure sufficient oil levels before finishing maintenance.

When the hydraulic fluid is insufficient, it can damage some important parts of the system. So, you will need to inspect the hydraulic cylinder. The overheating could profoundly affect the cylinders. If there is partial or total damage in the cylinder, this calls for a new cylinder.

8. Fuel problems

Your Kubota b7100 should not face any fuel issues if you use the right fuel and keep the fuel parts clean and well maintained. However, fuel issues can be a problem for countless tractors. If your tractor emits dark exhaust, this should alert you about the presence of a fuel issue.

Black smoke from a diesel engine can tell that the air and fuel blend is incorrect. It means the engine receives excessive fuel without a proper air ratio, eventually damaging the engine. As a result, ensure that the air filter is clean or replaced to pass the required air levels for combustion.

Kubota B7100 problems: are they a deal breaker?

No, all the widely discussed Kubota B7100 problems do not make this tractor unsuitableThe Kubota b7100 offers everything you want from a compact utility tractor with a powerful diesel engine. It is built to last for decades with proper care.

The best part is that this tractor is a suitable option for anyone seeking a cost-efficient tractor with a reliable warranty. This machine has a high ground clearance, which is almost 30 cm. The engine has three cylinders to make it capable of continuous hours of hard work.
