Kubota Zero-Turn Mower Problems: Causes and Solutions

Kubota Mower Fails to Start

If your Kubota mower won’t start, it might be because of air or gas restrictions not allowing the engine to get the required air and gas to run.

This can occur as a result of a defective spark plug, a bad solenoid, a failed electrical component or a dead battery.

Mower Loses Power and Dies

Your Kubota zero-turn mower can lose power when the air or gas systems are compromised, affecting the mower’s operation.

This problem may be related to clogged fuel lines, a dirty carburetor, a bad air filter, and bad gas.

Cause Reason for Problem Solution
Bad Gas Gas degrades over time making the fuel less efficient and liable to engine damage and clogging the fuel system Drain the gas tank and fill it with fresh gas. Use fuel additives to stabilize fuel
Broken or dirty cooling fins The cooling fins may be filled with oil, grass, and dirt which will not allow the air to properly cool the engine block Clean the cooling fins orreplace them with new ones
Blocked air filter Grass and dirt can block the air filter to prevent air flow Remove the filter andclean it. Replace it if it is in a bad condition
Clogged fuel lines Dirt and gas deposits can accumulate and block the fuel lines, causing the engine not to get the required gas Clear the clog out the fuel line by using compressed air and carb cleaner
Dirty carburetor This may be caused by bad gas and ethanol deposits which prevents the flow of fuel Clean all the parts that make up the carburetor or replace if needed

Kubota Zero-Turn Mower Smokes

Your Kubota zero-turn mower can smoke when the oil gets into the cylinder and starts to burn off.

How-To fix a FLOODING Carburetor on YOUR riding lawn mower/ lawn tractor.

Some parts begin to burn as a result of increased friction from low oil capacity. This can also result in internal engine failure.

Cause Reason for Problem Solution
Internal problems including engine gasket, piston ring or valve train Internal engine problems may cause serious effects if they are not quickly detected and fixed Take the mower to a local small engine shop for fixing
Low engine oil level Lack of oil may increase friction in the engine, causing extreme heat in the engine Take the mower to a small engine repair shop to check for engine damage
Blocked air filter Grass and dirt can block the air filter which prevents air flow Take off the air filter and clean it or replace it if it is bad
Excess oil in the crankcase Too much oil can cause pressure to build in the engine, enabling oil to gain access into the cylinder through the valve train Drain a little engine oil until it meets manufacturer’s recommended oil level

This problem may come from faulty components like kill switch, transmission cable and throttle/choke control cable.

Fix: To test this, remove the spark plug and push the mower blade to engage the button with a power cord.

If it engages, it means that you need to replace the transmission solenoid.

Check for any faulty or damaged wiring of the kill switch.

This is located behind the front panel, below the engine compartment or underneath the seat. Replace the kill switch if it is faulty.

Lastly, ensure that the throttle/choke control cables are okay and are properly seated in their base. Replace them if they are defective.

How Do You Clean the Carburetor on a Kubota Zero-Turn mower?

Here are the steps for cleaning the carburetor of your Kubota zero-turn mower:

Spray Carburetor Cleaner Into The Air Intake

The first step to take is to remove the air filter from the air filter housing. Spray the carburetor cleaner into the air intake.

Check if the engine will start and continue to operate. If the engine does not start but shuts down, you need to disassemble the carburetor for cleaning.

Take Pictures for Reassembly

It is advisable to take photos while you disassemble it. Some components might come apart and you may find it difficult to remember their position when you have disassembled them.

Taking photos of this process will enable you to reassemble them with ease

Turn off the Fuel Supply

To shut off the fuel supply, you need to use pliers or a fuel hose pinch to crimp the fuel line. You can also turn off the fuel shut-off valve. After that, take off the fuel line from the carburetor.

Take off Choke Cable and Throttle Cable

Remove the choke cable and throttle if your mower has one.

Remove the Filter Housing

Take off the nuts and screws that attach the carburetor to the filter housing.

Take Off the Springs

Slowly remove the springs but you need to be careful not to stretch them out.

To remove the springs, you have to twist the carburetor a bit. Ensure that you do not tear the gasket that is found between the carburetor and engine block.

kubota, turn, carburetor, 2014, zero-turn, mower

Remove the Float Bowl

You can locate the float blow at the base of the carburetor. The float bowl is where the gas is stored in the carburetor. This component is held by a screw.

Before removing the bowl, ensure that you clean around the outer part of the carburetor bowl to eliminate dirt. After that, remove the screw from the bowl’s base.

Make sure that you get a rag to catch the remaining gasoline in the bowl.

Do not damage the o-ring while trying to remove the bowl. In addition, make sure that you do not get the carburetor cleaner on the o-ring.

Inspect the Stem for Plugged Holes

A clogged stem will prevent the carburetor from bringing fuel to the jet. Locate the holes with a flashlight and disconnect them with a thick wire.

Inspect the Carburetor for White Crusty Build-up

Use a carburetor cleaner to remove white crusty material. It is quite impossible to get all the white deposits out of the carburetor.

Reassemble the Carburetor

After cleaning, you can now reassemble the carburetor. Check the photos that you took earlier to be sure that the parts are in the proper position.

Reattach parts to the carburetor including choke and throttle cable( if it uses one), fuel line, filter housing, and springs.

Fill the Gas Tank with Fresh Gas Mixed With A Fuel Additive

Fill the gas tank with fresh gas and mix it with a fuel additive. Allow the gas to fill the carburetor’s bowl and start the engine.

Note: You may need to replace the carburetor if it is in a bad condition.


If you notice that your Kubota zero-turn mower is giving you issues, the first step to take is to figure out the causes. Some of the problems include vibration problems, weak hydrostatic transmission, and starting issues.

Follow the recommended fixes to get your Kubota zero-turn mower working again. If your mower does not work properly after trying these troubleshooting tips, it might be best to seek a technician’s help.

14 Zero-Turn Mower Preview

A look at key trends in commercial zero-turn riding mowers, along with what leading manufacturers are introducing for this season.

It appears as though manufacturers of commercial zero-turn riding mowers have had their engineers working overtime as of late. Many mower makers are offering numerous updates, improvements and brand-new models for this season. It’s no wonder. With commercial riding mower shipments to distributors and dealers expected to see double-digit growth this year, new products sporting improved features and new technologies will be first to grab landscape contractors’ attention in the lead-up to spring.

An overarching trend in the commercial riding mower category relates to fuel. Electronic fuel-injection engines (primarily from Kohler), which help to significantly reduce fuel consumption, have become common. Propane-powered mowers are also on the move. The Propane Education Research Council ( PERC ) says 16 mower manufacturers now offer propane models. Kohler has even developed a double whammy: an EFI propane engine initially offered to Exmark and Toro but soon expanding to other manufacturers. And then there’s John Deere, who collaborated with Kohler to develop a flex fuel zero-turn compatible with ethanol blends up to E85.

In addition to fuel efficiency and alternatives, mower manufacturers continue to emphasize productivity. Some of this year’s new models feature larger drive systems (14cc or 16cc pumps and wheel motors) for faster speeds. A variety of suspension systems are designed to improve both operator comfort and cut quality.

Rear-discharge decks are also getting more attention. Several manufacturers—including Exmark, Toro, Hustler, Walker and Grasshopper—have expanded their offerings of rear-discharging mowers over the past couple of years.

Finally, high-tech is finding its way to commercial mowing equipment. For example, Husqvarna’s SmartSwitch allows for key-less operation, while also offering real-time feedback on battery performance. Technology from Exmark (RED) and Toro (Horizon) also offer real-time feedback. These technologies constantly measure a host of mower vital signs to guard against catastrophic engine and equipment failure. RED and Horizon can also make important decisions for the operator, such as which performance mode to select depending on mowing conditions.

Here’s a look at what some of today’s leading brands of commercial zero-turn mowers have been up to.

Related Questions

When is it worth replacing the engine instead of buying a whole new mower, pressure washer, or another device?

It is essential to weigh the cost of repairs against the price of a new device. If there is extensive internal damage, it may cost more to repair than it’s worth. Extensive damage to pistons or the crankshaft can cost almost 1,000 to repair. Buying a new riding lawn mower may only cost 1,000 more than that. If you’re willing to shell out a bit more for a new mower, do that instead of replacing the engine, but make sure you know which brands to avoid.
