(1) Problem 1: Bogging And Stalling Problems
Many customers have said their Kubota KX 121-3 bogs down or stops working.
Customers have said this happened to them after an excavator had already been sitting still for a few days. When the car started, it started to slow down, and the engine sounded like it was about to die.
When you try to start a machine, it stops and starts again. It doesn’t matter if the machine runs idle, with no load, or at half throttle. It will run perfectly, then suddenly miss, sputter, shake, or almost die. Black or white smoke will come out of the exhaust.
After working smoothly for a few seconds or even sometimes up versus two or three minutes, this will stutter again. The sound of the fuel pump stays the same; it doesn’t seem to speed up or slow down.
Solution
Most of the time, bogging and stalling is caused by not enough fuel, bad fuel, or much engine oil.
- Check how much fuel is left as well as add more if you need to.
- If it’s needed, a fuel system must be cleaned.
- Make sure you always use high-quality fuel.
- Sink engine oil to give a prescription oil level.
(2) Problem 2: KX121-3 Engine overheating
A water pump seal could indeed make the engine get too hot. If a seal has been leaking coolant from the inside, a coolant would be pumped out from the engine and won’t go back into the radiator.
This can lead to a temperature in the engine that is too high for regular operation.
Also, if the seal leaks on the outside, coolant will leak out of the cooling system, which is another problem.

(3) Problem 3: Excavator Hydraulic thumb Problem
Kubota Mini Excavators often have this problem. Even if you do not have a thumb connection, you should set your thumb solenoid valve to neutral when you’re not using it.
If this isn’t done, they will wear down your excavator’s hydraulic cylinders, which will eventually cause the hydraulic cylinders to break.
A thumb control valve is connected to the main hydraulic pump, so it pulls from the main pump when it is turned on. This causes your cylinders to wear out faster.
Solution
Check to see if the thumb valves on Kubota KX 121-3 excavator are stuck or won’t move.
Make sure that the hydraulic pumps and tanks here on Kubota KX 121-3 excavator have valves that let the pressure out.
Check if there are oil leaks or air as in Kubota excavator KX 121-3. Check the Kubota excavator’s thumb cylinder for leaks, rust, and cylinder rods that are stuck together.
(4) Problem 4: Excavator Won’t Start, Only Clicks
It takes a lot of work to start the Kubota excavator. Some people have had trouble with their machine clicking. When you try to start, all the lights flash, and the relays keep clicking.
You may understand a loud buzzing sound when you turn the key to start. Unless your Kubota excavator doesn’t turn on, it might be because:
Dead battery, rotted battery terminals, softer battery connection, poor safety switches, terrible starter motor, starter solenoid, terrible starter relay throughout fuel lines, failing fuel system, bad fuel quality, engine overheating, clogged fuel filter, and fuel lines.
Solution
There could be something wrong with the batteries. Ensure that the connections between the battery and the motor are all clean and tight.
The voltage and life of the batteries should be checked, so if new batteries are needed, they should be put in.
Maybe the fuel needs to get to the cylinder. It’s essential to check the fuel level, fuel shutoff valve, and fuel filter again.
(5) Problem 5: Fuel Delivery Problems
The cutting head will be on this Kubota KX121-3 fantastic series mini excavator. This could cause a problem with how fuel is delivered.
The injectors or even the injection pump are to blame. If you see black smoke, it could be a sign of this problem.
This problem may be caused by the bent “apparatus,” which is a part of the injection pump. This has caused the fuel rack to wear out.
Solution
Take the injection pump out and look for the word “apparatus.” Most likely, this problem will be fixed by adding new parts to a fuel injection pump.
A new fuel rack deserves to be put in place when the old one is too worn. This issue can be resolved completely by putting in a brand-new injection pump in place of the broken one.
