Kubota is a brand leader in the lawn tractor field, but it’s not a stretch to say that the L3560 is one of the most sought-after tractors, even among Kubota machines.

The reason is simple: it’s a concentration of power, durability, and performance. It can lift to an impressive 2646lbs, which is incredible for its size.

However, some users reported issues with the diesel engine and steering wheel. What is all the commotion about? Let’s check the most common Kubota L3560 problems and how to fix them!

The most common problems with Kubota L3560

When you think about a compact tractor, the first names that come to mind are probably those of John Deere, Cub Cadet, and, last but not least, Kubota.

Indeed, Kubota utility vehicles are long-lasting and impressive in their performance.

The L3560 model, in particular, has been acknowledged by many users as an excellent machine that lasts for many years without specific problems.

People love its more giant operating station in particular and the many features it has. All in all, it seems that the Kubota L3560 exceeded expectations!

Nonetheless, even the best tractors have their flaws. You might get away without expensive repair costs for most of these issues.

1. Diesel issues

This seems to be a shared experience of Kubota owners since the Kubota L4701 also has the same issue.

Sometimes the loader doesn’t work because the diesel doesn’t rotate.

This happens when you use the wrong type/grade of fuel in your Kubota tractor.

The Kubota company recommends that tractor owners use fuel with an API rating of CF or higher.

You should check the fuel injection pump if the fuel isn’t the issue. If its timing is incorrect, the energy isn’t delivered to the engine when needed.

2. Engine not starting/stopping issues

The engine of this tractor model seems to have problems both starting and stopping at times.

This is a very general malfunction that can be linked to various issues, so it’s fundamental to find the cause for each case.

Most of the time, this is a seasonal problem. For example, in winter, the viscosity of the oil increases, and thus the engine slows down.

The solution is easy; you need to replace the oil more often during the difficult season.

When it’s not a seasonal issue, it could be a fuel system or battery problem.

If it’s related to the fuel system, you should inspect the fuel filter and make sure the fuel flows in and out of it. If it stops at the filter, it needs cleaning or replacing.

This could also be a seasonal problem if you can link the issue back to the battery.

In winter, you should remove the battery from the mower to store it and charge it in the garage. Mount the battery only when you’re using the tractor.

When the issue doesn’t apply to winter only, you should clean the battery terminals and cables and see if that changes anything. If not, replace the battery.

3. Engine power issues

A low fuel level or old fuel can slow down the engine quite a lot and create a hindrance to your work.

Make sure the fuel in the tank is always at the proper level, and possibly, it should be fresh. To ensure a load of new fuel, go to the busiest station in your area.

Another reason diesel engines act up is linked to the air filters. When they’re clogged, they can cause quite a few issues with your Kubota.

As you can see, this issue can be easily prevented with good ol’ maintenance.

4. Engine overheating issues

This is a widespread problem with heavy-duty machines. Usually, there isn’t a single cause because it builds up different issues.

The most common reasons why the engine of a mower like the Kubota L3560 overheats are:

  • dirty radiator
  • engine overload
  • defective fan belt
  • faulty coolant system

With that said, there are also different solutions to this problem. Let’s check them:

  • shift to lower gears to reduce the load on the engine
  • practice regular maintenance and cleaning
  • check for loose connections in the radiator and hoses
  • keep the coolant filled to the required level
  • change the fan belt
  • flush the cooling system

5. Steering wheel issues

Too much free-play at the steering wheel could translate into dangerous situations. This problem must be addressed and solved as quickly as possible.

A variety of issues can cause a loose steering wheel, so we compiled a list of the main items you need to check to troubleshoot this problem:

  • There is a low hydraulic oil level. Refill the tank.
  • Tire pressure is uneven. Bring the tractor even to the ground and adjust the tension.
  • The power steering pump is broken, or the power steering is worn out and needs replacement.
  • The steering cylinder has broken down due to normal tear and wear. It needs to be replaced immediately.
  • There is air in the steering system or the hydraulic system. Please remove it.

6. Exhaust fumes issues

Seeing colored emissions from your Kubota tractor is never a good sight. You might already be wondering how much that colorful show will cost you.

Luckily, it’s easy to assess the issue by the specific color of the fumes, and there is a solution for every problem.

Diesel engines may emit black or blue-white smoke at times:

  • Black smoke: the fuel tank is over-filled; the air filters are clogged; the fuel is of low/poor quality.
  • Blue-white smoke: the injection nozzle is faulty; the exhaust mutter is damp from the fuel.

Once you have observed the specific color of the fumes and know which components to check, here’s what you can do about it:

  • The solution for black smoke is to change the fuel and its filter and not over-fill the tank. Clean the air filters or replace them.
  • Solution for blue-white smoke: increase the load on the engine to heat the muffler and check the fuel injection nozzle to see if everything’s working correctly.

Kubota L3560 problems: are they a deal-breaker?

Not at all! The Kubota L3560 is widely considered an excellent machine; the problems described above are widespread in many compact tractors.

Furthermore, these issues can be easily prevented with regular lawn mower maintenance and remembering to consider changing factors like seasons.

The Kubota L3560, like most Kubota tractors, is bound to be very durable. Still, over time the maintenance of your mower becomes increasingly essential to keep it in good health.

Even if some of these problems appear during the L3560 lifespan, now you know how to troubleshoot and fix them quickly!
