Kubota Zero Turn Mower Problems

Kubota Zero Turn Mower Problems And Their Solutions

If your Kubota mower has ever broken down, you may have wondered what caused the problem and why it happened. We’ll discuss some of the most common issues that Kubota mower owners have below.

(1) Problem 1: Poor Cut Quality

My Kubota ZT272 is leaving brown spots where it has been mowed.

Solutions

If you know enough about how to take care of your lawn, you can just put all four wheels in position 1 or 2 to change the height of the cut until you get the size you want.

If you don’t know how to take care of your lawn well enough, call a professional to help you set the correct height of the cut.

(2) Problem 2: Machine Won’t Start When Warm

After my Kubota Z482 has been running for a while, I start it, but the engine only sputters.

Solutions

Several things could cause this, but the most likely one is that you need to empty your gas tank and fill it with fresh gas that doesn’t contain ethanol.

This should fix the problem since ethanol gas eats away at the small holes in the carburetor, making it hard to start the engine after sitting for a while.

The second reason could be that you have low oil pressure. If this is the case, check your manual to see how to check the oil level. If it’s soft, add more oil and start the machine again.

The third reason is that the ignition coil or wiring is destroyed because the kill switch was turned on before the engine was entirely turned off by activating the parking brake.

In both cases, there is no easy fix that can be done without the help of a professional.

(3) Problem 3: Wheel and Belt Tension

When I drive my Kubota ZT282, the belts are not tight, and the wheels squeal.

Solutions

When the belt has been used for 100 hours or three months, depending on which comes first, the tension needs to be changed.

To do this, lift the deck off the ground, remove any bolts holding the transmission cover, and slide it back slightly.

You can now see your idler pulley. Pull your belts through the idler pulley and tighten the bolts holding it in place to make sure they aren’t too tight or too loose.

(4) Problem 4: Blade Dragging

I try to move my Kubota ZT22 but it feels like something is holding the blade down.

Solutions

A few things could cause this. You can check to see if the parking brake is set correctly and if the belt tensioner pulley has enough tension to keep the blades in place while mowing.

If the parking brake is set right and the belts still don’t have enough tension, you may need to tighten all four idler pulleys until the straps have the right amount of pressure. This is done after shifting the transmission into the drive gear.

The second reason could be that you have low oil pressure. If this is the case, check your manual to see how to check the oil level. If it’s soft, add more oil and start the machine again.

The third reason, which isn’t as common but could still cause problems starting the car even after new parts are put in, is that the ignition coil is broken or the wiring is wrong because the kill switch was turned on before the engine was completely turned off by using the parking brake.

In both cases, there is no easy fix that can be done without the help of a professional.

(5) Problem 5: Mower Deck Won’t Raise All The Way

I’m trying to engage the mower deck lift lever to raise it but it just goes back down.

Solutions

Most likely, this is because your lift cable is broken or disconnected. This can happen for several reasons, such as when a deck hits something or wears out.

To fix this, you’ll need to take the mower deck off and find the lift cable on the right side of the machine. If the line is broken, you’ll need to replace it.

The second possibility is that the height limit switch is broken. If this is the case, you’ll need to replace the height limit switch for the deck to go up.

The third reason is that the ignition coil or wiring is destroyed because the kill switch was turned on before the engine was entirely turned off by activating the parking brake.

In both cases, there is no easy fix that can be done without the help of a professional.

The fourth, less common reason the mower won’t start is if the solenoid is broken and won’t let the mower blades engaged. This could happen even if the parts have been replaced.

A broken transmission cable is the fifth thing that could happen between the height adjustment knob and the height limit switch.

If this is the case, you’ll need to remove the rear engine cover and find the cable inside the machine. If it’s broken, you’ll need to replace it.

(6) Problem 6: Transmission Slips In Gear

I’m trying to mow my lawn with my Kubota ZT22 but the transmission slips when I try to go faster than a slow walk.

Solutions

This is probably because too much grass or other debris is stuck in the deck or under the mower, which stops the blades from turning and keeps the torque converter from sending power to the wheels.

To fix this, remove any extra buildup from the top of the deck and use a putty knife or screwdriver to remove any debris from underneath.

The other possibility is that one or more of your belts are worn out and need to be replaced.

The third, less common, is that the ignition coil is broken or the wiring is messed up because the kill switch was turned on before the engine was completely turned off by putting on the parking brake.

This could cause the car trouble even after replacing the parts.

In both cases, there is no easy fix that can be done without the help of a professional. The fourth possibility is that the torque converter is stuck because it isn’t getting enough lubrication.

If so, remove the engine’s back cover and add multi-purpose synthetic power steering fluid to the reservoir until it reaches the red or white line.

You will also need to look for leaks around the drain plug for the torque converter and replace them if you find any.

(7) Problem 7: Mower Stalls Immediately After Started

Mower Stalls Immediately After Started

I press the “Engine Start Button” on my Kubota ZT22 but it just clicks instead of starting.

Solutions

The handle’s throttle/choke control cable may be damaged by hitting an object with a deck or simply wearing out.

To fix this, remove the mower deck and locate the throttle/choke control cable on the right side of the machine. Check for damage and replace if necessary.

The kill switch or wiring may be defective. Replacing the kill switch under the seat and the wiring behind the front panel below the engine compartment will fix the problem.

Faulty transmission solenoids prevent mower blades from engaging.

If so, remove the rear engine cover, locate the solenoid within the machine, check for damage, and replace it if necessary.

Fourth, your battery may not be charging due to a faulty alternator or wiring.

Using a multimeter, remove battery wires and check the voltage. If it’s below 12 volts, replace the battery.

If the fuel filter is clogged, remove the fuel cap and clean it before replacing it.

The sixth possibility is that your carburetor is malfunctioning, which can be fixed by replacing the air filter on the engine side and starting the mower without the mower deck.

If it starts but dies instantly, remove the fuel cap and clean the inside. If this doesn’t work, replace the carburetor.

A defective priming bulb or clogged fuel line may prevent your mower from starting.

If so, look for leaks around the priming bulb or tank neck damage where the hose connects. Fix all faulty parts.

(8) Problem 8: Mower Won’t Stop

I press the “Blade Engage Button” on my Kubota ZT22 and it just keeps going.

Solutions

This is probably because you have a broken kill switch or a problem with the wiring. This can be caused by several things, like hitting something with the deck or getting old.

To fix this, you’ll need to remove the mower deck and look under the seat for the kill switch. If it’s broken, you’ll need to replace it.

If the wiring is broken, you’ll have to replace it behind the front panel, right below where the engine is.

Another possibility is that your throttle/choke control cable is not correctly seated in its base, which can also cause the blades to keep turning even after you let go of the edge engage button.

This is easy to fix by ensuring the cable is in the right place and isn’t broken. If it still doesn’t work, you’ll need to change the line that controls the throttle and choke.

(9) Problem 9: Mower Blades Won’t Engage

I press the “Blade Engage Button” on my Kubota ZT22 but nothing happens.

Solutions

This probably means you must replace your transmission cable, kill switch, or throttle/choke control cable.

To test this, remove the spark plug and push the blade to engage the button with the power cord. If it engages, you’ll need to replace the transmission solenoid. Try replacing both parts, just in case they’re worn out simultaneously.

If it still doesn’t work, check the kill switch under the seat or behind the front panel just below the engine compartment for damage or bad wiring.

Also, ensure the throttle/choke control cables aren’t broken and are correctly seated in their bases.

Kubota Zero Turn Mower problems: Are they a deal-breaker?

You can avoid many problems with a Kubota Zero Turn mower if you maintain regular maintenance and service. Your experience as a user will be pretty smooth and pleasant.

No tractor is immune to needing good maintenance, which is why we have no problem recommending Kubota mowers as a good purchase.

Users have said they are pleased with their purchase, and their problems are not unusual or too much for what they are meant to do.

What Do the Customers Say?

Many people with Kubota ZTR mowers have used them for years without problems. It is much more durable and reliable than Hustler, Kawasaki, or John Deere.

Some people like their Kubota zero-turn mower so much that when they hear the word “smooth,” they think of their mower.

If you want to solve the problems, I listed above, you should talk to your dealer. They are accommodating, and Kubota ensures you get the service you need as long as you are still under warranty.

Stiff Handles

Some customers were unhappy with how stiff the handlebar was. There are a lot of older people who can’t work.

There appear to be two main things going wrong. Either the manufacturing bots tighten the bolts too much or are not greased enough.

PTO Problem

Your PTO may not work for several reasons. So, the customers are right when they say that PTO doesn’t work on the lower deck.

Most of the time, the problem is caused by a safety switch that won’t let it work. You would know what the safety switches are if you read the manual.

Even if everything works fine, you might need to move up a level or two. Check the two wires hooked up to the PTO clutch with a voltmeter (keep the key and PTO switch on but the motor off).

The clutch is broken if you see a small amount of voltage in the line. If not, something else further down the line isn’t working right.

Starting Problem

The most common problems with starting a Kubota zero-turn mower are that it sometimes won’t turn on or won’t turn on at all.

Since these machines run on gasoline engines, it can sometimes be too cold. A dead or weak battery could also be the cause.

Some people have even said they took out all the other parts and tried to start the engine. But no luck.

First, it could be a problem with the connection that can be fixed by cleaning the terminals. If not, you’ll need to take it to a nearby auto supply store and let the experts check it out.

Overheating

Another common complaint from customers is that the car gets too hot. Like the last problem, this one is caused by several things.

But you can guess that it’s because a filter is clogged. After a specific mowing time, the grass and dust usually get caught in the filter.

So, you should keep the filter clean and check on it occasionally. If not, it could hurt the radiator. In the end, the radiator problem leads to some other issues.

Fuel Line Issue

If you look at some videos on YouTube, you’ll see that some people are talking about problems with the fuel line on their Kubota zero-turn mower.

When the user turned on the mower’s engine, they felt terrible about it. He thought that something was using more electricity than it should.

Even though he took it to the dealer, the problem was still there. When he started angrily, Kubota gave him a new set of parts.

The experts found that the problem was caused by parts that had broken off in the fuel line. The guy had a warranty, so he just changed the fuel line, and the problem was fixed.

The mower produces unwanted smoke

Even though this is likely to be very scary at first, don’t worry! Most of the time, this is because the filters are letting the extra fuel burn off.

The airflow will be slowed down if your air filter is clogged. This will cause smoke to come out, so you should clean it.

Also, if there isn’t enough oil in the engine, it can smoke and damage parts like the piston rings and gaskets. So also make sure the oil is full.

If there are any leaks in the engine’s fuel system, oil drops may get on the engine or muffler and burn off, making smoke. So, check the machine carefully for leaks and fix it if you find any.

The mower vibrates

With a Kubota mower, you can expect to feel some shaking. But if it’s too much, it could mean that the clutch bearing is going bad, that the Kubota tractor’s blades are out of balance, or that the spindle/pulley bearings are going bad.

The best thing to do here is to check the machine and replace any parts that aren’t working.

It would help if you also looked inside the Kubota tractor for things like rocks or an acorn that might be stuck. The machine can add much to the vibration when running at full speed.

The mower is leaking gas

One problem with gas leaks is that they often dry up, making it hard to determine where the leak is coming from. One of the most obvious signs is if you keep your Kubota lawn mower in an enclosed space for a long time, and you can smell gas when you start it up.

To do this, all the fuel system parts will need to be looked at pretty closely. This can include the fuel filter, the fuel pump, the fuel lines, the shut-off valve, and the fuel cap.

All of these places should be carefully checked and fixed as needed. If you can’t determine where the leak comes from, a trained repairer should look at the lawn mower.

Stingers

Stingers are clumps of uncut grass left behind the mower. They are usually caused by a mistake by the operator or by not taking care of the blades. Here are some of the reasons why there are stingers in your yard:

  • Dull blade
  • Worn blade
  • Clogged deck
  • Ground speed is too fast
  • Engine speed is too slow

The cutting height doesn’t adjust correctly

If you spent all this money on a good cutter, you’d expect the quality of the cuts to stay where you set them.

But if the result doesn’t match the height you chose on the lawn mower, this could mean that the height limit switch is broken.

Since this is not easy to fix, you should replace the switch.

Final Thoughts
