6 Solutions For Kubota Tractor Forward Or Reverse Movement Issue

Loose connectors and unresponsive keys are typically the most common reasons why your tractor might not move. However, that doesn’t mean that problems are limited to these two causes only. 

Below, we have compiled and listed six of the most useful solutions that you will need to know in order to fix your Kubota tractor. 

1. Broken Axle: Replace The Axle

Replace The Axle

Often, it might be the fault of your axle that the tractor will not go forward or backward. This is usually caused by broken or faulty axles that allow the internal transmission fluids to drain quickly. 

Even if you have filled the transmission floods newly, if they get drained, the motor will not start.

While broken axles aren’t a huge problem on the engine, constantly losing and replacing the fluids can be expensive. As such, it is a better choice to fix up the axle before driving your Kubota tractor.

To patch up issues related to your axle, you should run regular maintenance at a certain interval. This involves screwing the axle properly and taping spots up when needed.

If none of the above maintenance points work, your only option might be to replace the entire axle. 

If you are going to replace parts of the axle, the maximum that you might need to spend is around 100 USD. For the entire axle shaft, you can expect around 800 to 900 USD.

2. Jammed Valves: Clear Out the Blockages

Jammed Valve

Jammed or blocked vents are one of the most common reasons why your Kubota might not move in any direction. This is usually caused by the accumulation of rock sediments and dried oil that blocks the valves. 

Once the valves are blocked, no oil can be processed in your engine. This results in a cranky, sometimes overheating, engine. If left alone, this can even cause correlated components to burn out from the heat. 

To resolve the issue, all you need to do is clear out the vents. You can do this by making use of a cleaning agent and wiping. Once cleaned up, the vents should be working as usual. 

Since you can resolve the problem on your own with the products you already have on your head, no labor cost is involved. If you need to buy a cleaning cloth and a cleaning agent, the total might be around 10 USD.

3. Unresponsive Keys: Replace The Keycaps

Unresponsive Keys

Unresponsive keys, as we have been mentioning since the start, are one of the root causes of your Kubota Tractor not moving forward or backward. While common, most drivers tend not to report it since it is easy to fix.

If you have unresponsive keys, the buttons in your controller will not work, no matter how much you press them. This is because no commands are registered due to either loose connectors or faulty keycaps. 

While the problem can arise due to various external conditions, time itself can also be a deterrent in causing the keys to show malfunctions slowly.  

To fix the problem, the best scenario is to replace the old keys with new working ones. In addition, you can also tighten the connection between the wires and the individual keys.

Fixing will cost about 80 to 100 USD on labor costs. In addition, you might need to pay an extra 10 to 20 USD depending on the keys being replaced.

4. Electrical Issues: Replace Sensors

Replace Sensors

Due to faulty electrical systems you may experience kubota tractor movement issues. Electricity problems are considered the most common problems seen in any tractor. Since it is one of the most experienced problems, it is also the problem that takes the least effort to fix. 

Symptoms included with electricity problems can include giving the wrong commands when pressing something else. In extreme cases, the entire controller might not work. 

To fix the problem, the best choice is to change the batteries or the fuse inside, depending on the exact problem causing electrical problems.

Besides the cost of replacing components, you might also need to pay a labor cost of around 50 to 100 USD. This is in case you decide to hire a mechanic to help out.

5. Wrong Or Stale Oil: Replace The Oil

Replace The Oil

Having the right oil or transmission fluid under use is a very important choice. If you use stale fluids, they can cause various problems. 

For instance, if you are using impure or old oil, they will not flow to your engine easily due to the differences in viscosity from what the kubota tractor engine requires.  

While this doesn’t really have any negative effects on your engine, this can cause your tractor to not move forward or reverse at all. As such, we advise you to change the oil as soon as possible. 

When changing the oil, make sure that the oil you are buying is compatible and safe for usage with your tractor’s engine. Otherwise, the same problem might persist, or the engine itself might reject the oil. 

The only cost involved here is the cost of oil. Note that the more carbon number, the more fluid you are going to have, and the more expensive it will be.

6. Extreme Outdoor Temperatures: Heat Up Engine Regularly

Heat Up Engine Regularly

Your Kubota tractor might not move forward or reverse due to the extreme outdoor temperatures freezing the vents or pipes. In addition, your tires can also contract or dilate depending on the climatic conditions. 

While not all of these issues can be solved on your own, If you are having tire issues, we suggest you change up to a new one. If certain components or pipes around the engine freeze, you could use rock salts to unfreeze them.

In addition, you will also need to take certain precautions if you intend to avoid engine problems. We advise you to heat up the engine every morning before using the tractor. 

There are no external costs involved in this solution. However, if you are going to change tires, you will be required to pay an average of 1500 to 2000 USD. 

In addition, if you are going to hire a professional to patch up certain issues like de-freezing the pipes, a labor charge will be applicable. This is usually about 50 to 100 USD.

Why Does My Tractor Click When I Start It?

The real reason why your tractor might click while starting might be due to a malfunctioning or near-malfunctioning solenoid. The solenoid connects the battery to the starter motor and produces electromagnetism to get the motor running. It clicks loudly if it can’t function properly.

You should find a black box under the hood of your lawn tractor. This is where the fuse connected to the motor is located. If it is removed, the circuit will be broken, and the engine will not work anymore.

How Do You Check If The Starter Relay Of My Kubota Tractor Is Working?

You can run a resistance test on your relay circuits to determine whether they are working. Connect a multimeter; if the reading is more than 5 Ohms, you will need to replace the replay.
