Common Problems of Kubota B7800 and their Solutions:
Here are some common problems relating to Kubota B7800 that I’ve penned down below-
1. Engine Overheating Problems
If your engine emits more heat than usual, it must take more than its capability. You can cut down some load or shift the excess burden to the lower gear.
You also need to check whether the coolant system is working or not. The coolant system facilitates the process of cooling your overheated engine. If there’s anything wrong with it, fix it or replace it with a better part.
2. Lack of Power on Engine
Poor engine power or power imbalance can cause great miseries for the Kubota B7800 user. Mowing your lawn needs an unhindered and constant power supply, and that’s why you need to ensure a spontaneous power supply to the engine.
There can be divergent issues why your engine lacks an adequate power supply. Clogged filters, injectors, or low fuel levels in the fuel tank can be the reason for it. You can also experience such disturbance if the air filter gets jammed by dirt.
Always maintain adequate fuel levels to ensure the overall health of your Kubota B7800 mower. Cleaning your mower’s air filter is an essential part of its regular maintenance.
Don’t forget to check your mower ignition system to resolve power supply hindrance. If the spark plugs or ignition coil are faulty, replace them.
3. Black Smoke
If your mower gets more fuel than it needs to operate, it’ll emit the extra fuel by forming black smoke. Black smoke is hazardous for both the mower’s condition and the environment.
The piston ring is broken if your mower creates black smoke from the exhaust pipe. Piston rings prevent your mower from infiltrating the engine oil into the combustion chamber.
The mower creates unwanted black smoke the engine oil starts flowing through the piston rings into the combustion chamber. Replacing your piston ring is the best that you can do in this situation.
4. Excess Fuel Consumption
If your mower’s consuming more fuel than necessary, there’s something wrong with the carburetor. A clogged carburetor or accidental leakage in the fuel line can be the reason behind it.
Poor fuel economy is significantly linked with clogged carburetors. A clogged carburetor is responsible for fuel overflow from the carburetor bowl vents and wetting spark plugs.
Maximum Ethanol fuels used these days attract moisture from the environment. And metal in touch with humidity gets corroded. As a result, the mower’s internal body parts get corroded and develop leakage.
Using a fuel stabilizer will resolve half of the problems. Besides ethanol deposits, it’ll also get you rid of carbon deposits. If you want to improve the fuel deposit of your mower, get yourself a fuel stabilizer.
5. Mower Cranks Without Starting
If your Kubota B7800 isn’t getting enough fuel through its hoses into the cylinder, you experience disturbing cranks. Inspecting the fuel valve, shutoff valve, and fuel filter can help.
The problem can also be in the air filter. Sometimes the air filter is too cold to combust air and fuel altogether. As a result, your Kubota B7800 engine starts cranking.
Replacing the air filter can help you get rid of disturbing cranks. Moving the throttle back to idle and then half throttle can solve this issue. Then your mower will operate smoothly.
