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.

Kubota Zero-Turn Mower Smokes

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

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

Weak Hydrostatic Transmission

A weak hydrostatic transmission may occur due to a worn or broken drive belt or tensioner pulley.

Mower Won’t Steer Correctly Or Drive Straight

Your zero-turn mowing machine may experience these problems as a result of bad dampers, worn steering parts, and incorrect tire pressures.

The tracking may be off on your Kubota zero-turn mower, causing it to veer off to the left or right.

Kubota Zero-Turn Mower Won’t Move

This is one of the common problems of a Kubota zero-turn mower.

This can occur as a result of a missing idler spring, bad drive belt, or worn tensioner pulley.

If the drive release lever and transmission bypass rod aren’t in the right position, it may cause the mower not to move.

Vibration Problems

The Kubota zero-turn mower may vibrate because of unbalanced or damaged blades, or failing components including bearings in the clutch, spindle housings, and pulleys.

Other possible causes include loose components and hardware on the mower, and debris lodged under the mower’s pulleys and other places where small items can get stuck in the mower.

Uneven or Bad Cut

Your Kubota zero-turn mower may cut unevenly because of defective components such as a damaged or worn blade, unleveled mower deck, uneven tire pressures, clogged mower deck and slow engine speed.

Engine Overheats

The engine of your Kubota zero-turn mower can overheat due to low engine oil level or restricted airflow, affecting the operation of the mower.

Leaking Gas

This issue may occur if the carburetor bowl gasket is damaged. This will affect the operation and functionality of the Kubota zero-turn mower.

Stiff Handles

Some Kubota zero-turn mower owners have complained about the stiffness of the handlebar. This occurs because the bolts are too tight or they are not well lubricated.

Blade Problems

If your Kubota zero-turn mower isn’t cutting grass well, it means that the blades have become loose and need retightening.

The major reason for this is wear and tear which won’t make the blades won’t spin well.

Tire Problems

Kubota zero-turn mowers come with large tires that can run into different types of obstacles such as stumps and rock.

This may also cause damage to one or more tires.

It is advisable to replace tires if you notice wear on them. In addition, ensure that the tire pressure is even on your mowing machine.

Kubota Zero-Turn Mower is Difficult to Start

Some Kubota owners have complained about the mower taking much time before starting. This may be due to a clogged carburetor.

When gas is left for a long time, it becomes sticky and clogs your carburetor.

Kubota Zero-turn Mower Not Getting Gas

If your Kubota Z231 or any other Kubota zero-turn lawn mower does not get gas, the problem may be due to:

• Bad Fuel
• Plugged fuel filter
• Clogged fuel lines
• Bad fuel pump
• Dirty Carburetor

Troubleshooting Tips

• Use a siphon pump to drain the gas tank and refill it with fresh fuel. Ensure that you add a fuel additive to the fresh gas to clean and stabilize the fuel system.
• Replace the clogged fuel filter with a new one.
• Replace the fuel line with a new one.
• Replace a damaged fuel pump with a new one.
• To clean the dirty carburetor, spray the carburetor cleaner into the air intake.

Kubota Zero-Turn Mower Blades Won’t Engage

A Kubota zero-turn owner once complained that the blades didn’t engage after pressing the “Blade Engage Button”.

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.

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.

Conclusion

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.

Kohler vs. Kawasaki Engines: Which One Is Better?

Trying to decide between a Kohler and a Kawasaki engine? Kawasaki engines are the most reliable, but Kohler often has better support services. Let us help you compare the two, so you can be sure that you end up with the engine that is best for your needs.

If you mow your grass, use a pressure washer, or similar DIY tasks, then you need hardworking, reliable machines. Your equipment’s usefulness is only as good as the engine, and Kohler and Kawasaki are some of the best.

Many popular mowers, pressure washers, and other devices, like John Deere and Craftsman, use Kawasaki and Kohler engines. Both engines are an excellent choice with many strong qualities, although Kohler tends to have better support service. Alternatively, Kawasaki tends to take the lead on consistent quality over the years.

No matter what your reason for needing a new engine, Kawasaki and Kohler are both viable options. However, take a closer look at both before deciding which is the best choice for you.

Things to Consider When Choosing a Small Engine

Before jumping into purchasing the first engine you see, consider all of the pros and cons of each. Several factors are essential when choosing a lawnmower, pressure washer, or any other machine using a small engine. You’ll want to look at things like reliability, fuel-efficiency, cost, and expected lifespan, among others, before making your final choice.

Power: Kawasaki vs. Kohler

Kawasaki is known for its Critical Power engines that follow SAE J2723 standards. This standard ensures that engines provide users with at least 98% of their rated horsepower. A standard of SAE J2723 Critical Power provides Kawasaki engine users with a more precise measurement of horsepower.

To ensure Kawasaki Critical Power engines are up to snuff, they go through rigorous testing done by TÜV Rheinland Group. Kawasaki utilizes a third-party testing group to prevent biases as well as guarantee precision in ratings. During testing, equipment and calculations are set to the SAE J2723 rating; tests are run, then the group assigns horsepower ratings.

Kawasaki’s Critical Power engines have more precise testing and ratings than other engines. In Kawasaki FX engines, horsepower ranges from 15.5 HP to 38.5 HP.

Comparatively, Kohler engines are not as well known for the accuracy of their horsepower ratings. Kohler’s gasoline engines have a wide variety of engines, ranging in horsepower from 3hp to 38hp.

The Winner: Kawasaki. Its engines are better known for the accuracy and precision of their horsepower.

Comparison Video: Kawasaki Kohler Engine Teardown

Reliability: Kawasaki vs. Kohler

In terms of reliability, Kawasaki is known for the precision of its horsepower ratings. When purchasing a device with a Kawasaki engine, you get the horsepower you expect. Users cite experiencing fewer problems with Kawasaki engines compared to other models.

Kohler engines are reasonably reliable, depending on the model you purchase. Certain models have had issues with oil leakage, but this is easily fixable. The new Courage model has a part that has a tendency to peter out in 50-100 hours. Kohler engines also have issues with cranking but not starting.

The Winner: Kawasaki. Users cite fewer problems with Kawasaki engines than Kohler engines.

Efficiency: Kawasaki vs. Kohler

Kohler offers users a variety of fuel options for its engines. Although some of its engines use gasoline, its most fuel-efficient models run on propane without a carburetor. Kohler’s Command PRO® EFI engine can save you up to 600 per year on fuel.

Some of Kawasaki’s lawnmower engines also forgo the use of a carburetor and utilize EFI instead. These engines allow users to speed up the pace and often feature high and precise cutting power. However, people describe Kawasaki as using more fuel than its counterparts.

The Winner: Kohler. Although both utilize EFI technology, Kohler has a reputation for using less fuel than competitors.

Brands That Use Kohler and Kawasaki Engines

You can find Kohler engines in a wide variety of brands, including Dixon, Toro, Cub Cadet, Ariens, and Husqvarna. You’ll also find Kohler engines in Gravely, Dixie Chopper, Craftsman, Westinghouse, and Simpson power equipment.

Kawasaki engines are not as widely used as Kohler engines. You can find them in brands like Ariens, Gravely-Pro, Snapper-Pro, Dixie Chopper, Toro, Husqvarna, Cub Cadet, and Swisher.

The Winner: Kohler. A broader range of companies uses its engines.

Maintenance: Kawasaki vs. Kohler

Kawasaki recommends you perform regular maintenance on its engines. Follow your user manual’s instructions to maintain the air filter, oil oil filter, and cooling system. Kawasaki engines use open-loop control, which requires less maintenance due to fewer parts.

Kohler also says to maximize your engine’s life perform regular maintenance as outlined in your product’s user manual. Perform routine maintenance on the air filter, oil and oil filter, and cooling system.

The Winner: Kawasaki due to its open-loop control system. This has fewer parts to maintain than Kohler’s closed-loop counterparts.

Lifespan: Kawasaki vs. Kohler

The lifespan of any engine is dependent on how well you maintain it. Motors will last longer if they are well taken care of and if you use them regularly. However, if you use your engine daily, it will experience more wear and tear and likely peter out earlier.

If well maintained, you can get almost 3,000 hours of use out of a lawnmower using a Kawasaki engine. Some users have maintained their Kawasaki engines well enough that they’ve lasted 15 years.

The jury is out on exactly how long a Kohler engine will last you. Some of its air-cooled engines will last about 2,000 hours, if that. Other users claim their Kohler engines have been long-lasting, going for nearly 4,000 hours with no problem.

The Winner: It’s a tie. Depending on how well you take care of your machinery, these engines can last for a long time.

Warranty: Kawasaki vs. Kohler

A 36-month limited warranty accompanies Kawasaki engines. If any part of the engine fails during this period, the company will cover repairs or replacement. However, an official Kawasaki engine dealer must do the repair for it to be free of charge.

Kawasaki’s warranty does not cover parts broken due to misuse, accidents, or poor maintenance. You can also purchase Kawasaki Protection Plus for additional coverage on a Kawasaki product.

The warranty on Kohler engines depends on the type of use intended for the product. The warranty period for residential use is typically longer than the warranty period for commercial or rental use.

Kohler’s residential warranties vary from one year to five years. Its commercial and rental use warranties range from 90 days to 3 years. The length of Kohler’s warranties is also dependent on what type of engine you purchase.

The Winner: Kawasaki, for a flat three-year warranty. Depending on what Kohler product you buy, you may get a more extended warranty.

Customer Service: Kawasaki vs. Kohler

Both brands have relatively similar customer service availability. Kohler’s customer service is available every Monday to Friday from 8 am to 5 pm. Kohler is known for its exceptional customer support service, being a bit friendlier than competing brands over the phone.

Kawasaki is available at the same time via phone as well as email. However, it will only respond to emails concerning repairs and warranties.

The Winner: Kohler. It’s known for better and friendlier customer service.

Cost: Kawasaki vs. Kohler

Kawasaki small engines for mowers range in price from 360 to 3,000. Kohler small engines range in price from 219 to 3,450.

The Winner: Kohler. You’ll find mower engines for about 140 less than Kawasaki engines. However, the two are very close in price, so weigh the features of each engine before purchasing.

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.

Consider repair when the issues are smaller, like making repairs to the carburetor. Smaller problems are usually a result of maintenance procrastination. Be sure to do maintenance as recommended, so you don’t have to buy a new lawnmower.

What are some other high-quality engine brands and some of their top qualities?

Alongside Kawasaki and Kohler, Honda, Briggs and Stratton, and Generac are well-known brands that make reliable engines.

Honda engines are best known for their reliability in push mowers. Briggs and Stratton has been making engines since the early 1900s and make reliable equipment. It also has parts readily available for replacement should your engine break down.

Generac makes durable industrial engines that have long lifespans.

Our Final Take

Both Kohler and Kawasaki offer superior engines, so consider the details when choosing the one that is best for you. If price is more important to you, Kohler has cheaper small engine options available for purchase. If power is more important to you, Kawasaki has precise ratings and high levels of horsepower.

Both brands have different things to offer you and your devices. Make your engine choice depending on what qualities are most important to you.
