Kubota B7610 Problems

1. Engine Not Cranking

Some common reasons why this happens is due to a dead battery, dirty or corded battery cables, or anything battery related. 

To Fix: You can fix these problems quickly by cleaning or replacing the battery cables; other times, you have to call professionals to check the battery out.

2. Overheating Engine

This problem is generally caused by a lack of proper airflow in and out of the tractor. 

When your radiator is clogged, it either blocks or reduces the airflow, and that eventually causes the heat to build up. Most times, this issue all states back to your radiator, and several ways you can fix this issue. 

To Fix: You can check your radiator fins and clear out any dust or debris particles from it; sometimes, that would most likely fix the issue. You can blow out the air quickly with an air compressor. 

3. The tractor Engine Keeps Shutting Down. 

If your Kubota b7610 keeps shutting down a few minutes after you started it, the problem has something to do with the fuel system. 

Trying to fix this issue can be very tricky, and you must have a strong sense of smell to fix this one all by yourself. 

When you inhale from the fuel tank, you notice that the engine would release a Strange odor after running for a few minutes and going off. 

The Kubota b7610 operates with a diesel system, and when it is squeezed, diesel burns, so the pistol compresses the fuel-air combination, causing it to ignite, thus, the foul odor. 

To Fix: The best way to quickly fix this issue is by draining all the fuel in the fuel tank and replacing it with a new one. 

4. Difficulty In Steering 

Some common causes of this issue include air being trapped in the steering system, a dirty or broken steering filter, a defective hydraulic steering pump, and an incorrect toe-in. You can fix this issue by addressing all the problems stated above. 

To Fix: Check your steering system by freeing the air from the steering system and checking on your hydraulic pump to ensure that it is not defective. You also have to ensure that you check and adjust your toe-in if it is out of place. 

5. Battery Refusing to Charge 

There are several reasons why the battery of your Kubota b7610 would refuse to charge, but all of these issues have an easy fix. 

Common reasons your battery would refuse to charge include loose or corroded electrical wings, defective battery terminal clamps, and damaged or loose belts. 

To Fix: You can fix the issue with your battery when it refuses to charge by ensuring that the electrical wings are not rusted; even if they are, do well to replace them, replace belts that are damaged, and replace belts or adjust the belt tension. 

6. Problems With the Diesel Engine 

If your tractor has a problem with the diesel engine, you will notice that the engine shuts off on its own while running, the diesel starts and stops, and you will also see that the engine makes an abnormal noise or constantly knocks out. 

When your engine starts and suddenly stops when running, it is either the injection pump timing is wrong or the engine has not warmed up to the required temperature. 

Also, when your diesel starts and stops, the fuel filter is plugged in, or the fuel injection pump is defective. 

To Fix: You can be able to fix this issue by changing your fuel filter element or cleaning or replacing the air filter element when it is dirty. 

7. Hydrostatic Transmission Issues 

Although the hydrostatic transmission issue is not common to the Kubota b7610 tractor users, this issue arises sometimes. 

Usually, the power of the mower’s engine is sent to the hydrostatic transmission through the treadle pedal, and when the treadle pedal has issues, it automatically affects the hydrostatic transmission. 

Some problems with the treadle pedals are usually due to too tight a joint on the bolts and the need to apply more lubricant before pedaling. 

To check if the pedal issue is from the hydrostatic transmission, you must push the pedal and check if the pedal is overly firm. 

To Fix: In this case, you do not need professional help, and you have to loosen the joint on the bolts a bit to lose the pedal if it is too firm and apply a bit of lubricant; that should work in this case.
