Engine Failing to Start
Whether new or old, your Kubota L3560 engine might sometimes fail to start. This problem is common during certain months, particularly in winter. However, if you’ve used your L3560 excessively for a long period, it might fail to start any time of the year.
What should you do if you have trouble starting your tractor’s engine? First, identify the cause of this issue. In most cases, this tractor’s engine fails to start due to the following:
- Thick oil
- Fuel system and fuel issues
- Battery problems
How to fix:
Since most starting issues in Kubota L3560 are seasonal, it’s advisable to check for increased oil viscosity in the tractor. When winter comes, the tractor’s oil will likely get thicker and cause starting problems.
If you have an engine block heater, use it to warm your engine and oil. Alternatively, drain the thick oil and replace it with suitable oil that retains its viscosity at ambient temperature.
Leaving the battery in your tractor during winter can also result in starting troubles. So, after using the tractor, remove the battery and store it in a warm room, such as your garage. You can reinstall the battery whenever you want to use the tractor.
If the problem occurs at other times of the year, check for corroded battery cable connectors and terminals. Clean them properly and tighten the connection.
Does the starting issue persist after fixing the above problems? If so, check the fuel system to see if it has any issues. Fill the fuel tank as necessary and replace a dirty filter. If there’s air in the fuel system, bleed it to allow steady fuel flow.
Engine Gets Excessively Hot
A Kubota L3560 engine that gets very hot while driving indicates issues with various components. Sometimes, this issue can cause other Kubota L3560 problems, such as loss of power and a dying engine.
Moreover, an overheated engine can damage the cylinders and the cooling system. It’s wise to stop using the tractor and deal with this issue first. So, if you’ve noticed that your tractor engine gets excessively hot, inspect the following:
- Blockage on the air intake
- Low coolant
- Dirty radiator core
- Defective fan belt
How to fix:
Dirt and debris can block your L3560’s air intake and cause the engine to overheat. If you’ve neglected cleaning the intake manifold, clean it thoroughly to remove dirt and debris.
Driving the tractor with low coolant can also cause the engine to overheat. Top up the reservoir with fresh coolant as necessary. You can also inspect if there are leaks in the reservoir and fix them.
Check the radiator core for dirt, debris, or a sludge build-up if the engine keeps overheating. To fix this issue, clean the radiator core with a towel and radiator cleaner.
Lastly, check the condition of the fan belt. A worn or defective fan belt might slip and fail to transfer power properly, causing the engine to overheat. Install a new compatible belt if necessary.
Exhaust Producing Colored Fumes
The L3560 tractor can start producing colored fumes while running it. The good news is that it’s easier to determine the cause based on the fume color. Generally, this tractor emits black or blue-white fumes from the exhaust. Let’s see what these colors indicate.
- Black: If the exhaust fumes appear black, the tractor might have an overfilled fuel tank, low-quality fuel, or a dirty/clogged air filter.
- Blue-white: If the fumes appear blue-white, the problem might be a faulty injection nozzle or fuel getting into the exhaust.
How to fix:
Black fumes: Check if your tractor has an overfilled tank and remove the excess diesel. If there’s contaminated or low-quality fuel, drain it and add high-quality fuel. Lastly, clean a dirty/clogged air filter.
Blue-white fumes: Inspect the injection nozzle and replace it if it’s faulty. You can also apply load to your engine to allow heating of the muffler.
Loose Steering Wheel
A loose steering wheel can be problematic when driving your tractor. Generally, a loose steering wheel will have excessive free play. Such a steering wheel can result in dangerous situations, especially when making emergency turns.
Since many Kubota L3560 problems occur due to poor maintenance, always keep the steering system in tip-top condition. However, if it becomes loose over time, address the problem before handling another project.
In most cases, the causative factors of the L3560 loose steering wheel are as follows:
- Low steering fluid level
- Worn or broken steering pump
- Broken steering cylinder
How to fix:
Most steering problems in your tractor might occur due to low fluid levels. So, check the fluid reservoir to see if the fluid level is low. Add the correct fluid to the required level. If you’re unsure which fluid to use, check what the Kubota L3560 manual recommends.
Next, replace the steering pump if it appears worn or broken. You’ll also need to replace a broken steering cylinder. If you can’t replace these components yourself, hire an experienced mechanic to do the job.
Engine Dying After Running for Some Time
Besides an overheated engine, other factors can cause your L3560 engine to die while running. It can be so frustrating if your tractor dies in the middle of a project.
If your tractor’s engine occasionally dies while riding, check for the following causes:
- Insufficient fuel
- Clogged fuel lines
- Malfunctioning fuel solenoid
How to fix:
The fuel system should be the first place to check if your tractor starts and stops after a while. Open the tank and check if an empty tank is the culprit. Refill the tank with fresh, high-quality fuel.
Check for clogged fuel lines if this issue persists despite having a full tank. You can blow high-powered air through the line with an air compressor. If you have a dirty or clogged fuel filter, replace it.
Lastly, check the condition of the fuel solenoid to see if it’s defective. Inspect the solenoid wiring and secure any loose connections. You’ll also need to replace any frayed or broken wires. If the problem continues, the solenoid might be faulty and needs replacing.
While the L3560 is prone to problems, it’s still one of the most reliable compact tractors on the market. It’s a powerful, durable, fuel-efficient tractor you can use on farms or homes.
If you encounter the above Kubota L3560 problems, address them promptly to prevent other issues from occurring. You can also refer to the Kubota L3560 manual to learn how to maintain your tractor and fix various problems.
