The most common issue that Kubota zero-turn mower owners face is their mower either doesn’t start or move.

- First, make sure that your mower has enough gas. If the tank is low, fill it up and try to start it again.
- Next, check to see if the mower key switch is in the correct position – typically, it should be placed in ‘On.’

- Ensure the battery is charged or the fuel is full.

Doesn’t Cut Grass Evenly
Having a beautiful lawn with evenly cut grass is the dream of many lawn lovers.
Unfortunately, not everyone is able to fulfill this dream because a mower doesn’t cut grass evenly. And it happens with Kubota zero-turn mower customers too.
Does this problem have a solution? Yes, and the best part is you don’t need to go to any technician; you can do everything yourself.
- 90% of the time, the problem with uneven grass is related to the blade. Therefore, check the blades of the mower whether they’re installed correctly.
- If they are installed correctly, then touch the edges of the blades (carefully by not putting too much pressure). Sharp edges mean the issue has nothing to do with blades, and dull edges mean you need to sharpen the blade.
- What if the blades are sharp? It means the issue is with the spindle. This part transfers the power from the engine to the blades. If it doesn’t work, the blades won’t work either. In case of a damaged spindle, replace it as soon as possible.
Zero-Turn Mower Overheats
Overheating is a serious issue because if you don’t take it seriously, your Kubota zero-turn mower might face serious problems with the engine.
But where to start? How to find the reason behind the overheating issue?
Rest assured, to help you out, we’ll discuss the possible reasons below and how you can spot them along with the solutions.
- Another issue that creates the overheating issue is the clogged deck. To solve this issue, lower the deck and check the bottom. If it’s clogged, then clean it and enjoy mowing the lawn.
- You should also check the mower blades. The reason behind it is that dull blades don’t work efficiently, and the engine has to put pressure in order for them to work, resulting in overheating issues.
- Have you heard about cooling fins? It’s the part that helps maintain the engine temperature. If it’s blocked by debris and grass, the engine will overheat. So, open the engine case and clean the debris for proper airflow.
According to many Kubota zero-turn mower customers, they sometimes feel that the mower deck vibrates whenever they try to use it.
At this point, some people think that the issue is with the engine, but it’s a misconception.
- What we’ve found out is that it mostly happens because of clutch-bearing issues. Otherwise, the problem must be with the spindle. So inspect both parts of the mower and replace them if damaged.
- If the first solution doesn’t help, check the bottom part of the mower and see whether there’s any rock or anything stuck.
Pulls to One Side
The fifth common issue is whenever we start the Kubota zero-turn mower, it doesn’t go straight.
It will either go to the left or right, and you’ll feel that you have no control over the mower. What should you do in this situation? We’ve two solutions!
- Mowers come with four tires, and if these tires don’t have equal and sufficient air pressure, you won’t be able to move them. When one of the tires doesn’t move, the mower will pull to one side. To solve this issue by checking the air pressure.
- Another main reason behind this issue is the steering levers aren’t adjusted, and you need to adjust them. The bolts at the center of the drive arms help you adjust them.
Deck Isn’t Lifting
The lawn mower comes with an amazing option which is deck lifting. You can adjust the deck level according to your preference.
But this feature sometimes doesn’t work, and when it happens, you won’t be able to set the deck.
There might be one of these reasons behind the issue.
- The zero-turn mower lifting cables are damaged, which makes it impossible for us to lift the deck level. In that situation, you need a professional because you can’t repair the wires without any expertise.
- Another issue is that the mower lifting system is connected to the height switch. This switch is available beside the seat, and its housing must have moisture, or the nuts must be rusty. You can open the housing and clean it to solve the issue.
Stops Working Suddenly
Among all issues, this one is the most dangerous one. It makes us panic all of a sudden, and we end up thinking that we’ve lost our mower.
Don’t worry; that’s not the case because mower zero turn mower stops working for many reasons.
- The first reason the mower might not be working is it has no fuel or old fuel. Besides that, the fuel lines might be clogged as well as the cooling fins. So make sure to fill the tank with new fuel and check the fuel lines and cooling fins.
