1. Shutting of Suddenly Arter Working for a While
Fuel flow issues are the most common reason for Kubota L3400 to stop working after running for a while.
If the tractor starts off good, works for some time, and suddenly stops while in use, the most common reason is fuel starvation.
The Fix:
There are several ways to solve this problem.
Firstly, check the fuel line. Disconnect the line which connects the fuel filter and the fuel pump. If the diesel fuel pours as it leaves the line, there may be something clogged in the line.
Use an air compressor to flush out if anything is clogged. If the actual problem is this, it should be solved by this method. If not try the second one.
Secondly, check and inspect the fuel filter. if it’s filled with dirt and thick mud-like object, you need to replace the filter.
Thirdly, the problem can be in the fuel injector pump. What this does is, it pulls the fuel and takes it to the engine from the fuel tank.
So, if there is any link of blockage in it, it can also create a problem.
2. Trouble Getting Started
Another common problem in Kubota is not getting started at all but just clicking. It generally happens if there are any battery issues.
So, you need to check the battery first if you are facing this kind of problem.

After that, check the voltage of the battery. This way you will get to know if the battery is dead. If it is, you need to replace it. Or if there is any faulty safety switch, it needs to replace too.
3. PTO not turning off
PTO is also known as Power Take-Off enables the driver or operator to use the tractor for multiple uses. It drives power from the tractor to the PTO-driven machine. Overall, it increases the productivity of the tractor.
You can face problems like the PTO not turning off even when the PTO lever is shifted to disengage. It happens when the spring load is seized up and does not slide properly.
The Fix:
Disconnect the two small wires you will find in the PTO lever. If it’s still on, check for the cable which runs from the PTO shift and goes into the transmission case under the seat.
Spray DW40 on the rubberboot and work the PTO shift back and forth. You will find the downside of the cable. Do it for at least fine munities. Do it again if you feel needed. It should solve the problem.
4. Slow RPM When Loads Heavier
This problem occurs mostly with heavier loads. When you load heavier the RPM shows down to an almost shiftless situation. After that, it will pick it up in about a minute or so.
After some time, this cycle will start all over again.
The Fix:
It generally happens when algae grow inside the fuel bowl. To fix this problem, you need to lean the fuel bowl first.
If the problem does not solve yet, replace the fuel filter. it should do the work.
You can also do a Biocide treatment and set it for overnight. You will feel like this is a new vehicle you are running.
5. Gear Transmission Issue
Not being able to use any particular gear is not a common problem, but it occurs sometimes.
What happens here is, that every other gear works fine and when you try to use that particular gear. It just stuck.
People need to turn off the vehicle to operate it again.

Check the gear compartment if something like stone or dried mud had stuck there. Mostly this creates the problem.
If not, try to see a professional who can fix the problem for you.
