Manual raking and cutting grass in the yard is exhausting. Good thing Troy Bilt’s zero-turn mowers allow you to do this with ease and comfort, even on larger grounds.
Of course, problems eventually arise in the long run. Our professional landscapers have compiled commonly experienced Troy Bilt zero-turn mower problems and how you can fix them.
Issue #1: Mower Won't Start
Similar to a John Deere mower that refuses to start, electrical, airflow obstruction, or an empty gas tank are typical reasons your Troy Bilt mower won’t start. Other aspects like the ignition switch, battery issues, and seat safety switches could also be to blame.
Check the gas tank and fill it up if it’s empty. Your local Troy Bilt dealer or a professional landscaper should check technical issues like faulty electrical wires and ignition switches causing your lawn mower not to pull or start.
Issue #2: Starts Then Stops
If your high-quality Troy Bilt mower starts then abruptly stops, it’s most likely due to an issue with the spark plug, engine oil, or air filter.
Replace old or worn-out spark plugs. Our professional landscapers recommend you check your equipment regularly for maintenance.
Issue #3: Mower Stops While Mowing
If your Troy Bilt mower stops while you’re in the middle of mowing, it’s likely due to an overheated engine. Mowers can also stop if there’s a problem with the carburetor, fuel tank, or air filter.
Allow the engine to cool down before continuing to use the mower. Clean the air filter and check the fuel tank for any blockages.
Issue #4: Hydrostatic Transmission Problems
The hydrostatic transmission allows you to have a smooth ride while mowing. But over time, the hydrostatic transmission fluid can break down and cause transmission problems.
If you’re having trouble steering or your mower is moving slowly, it’s time to change the hydrostatic transmission fluid. Our professional landscapers suggest you change the transmission fluid every 50 hours of use or once a year, whichever comes first.
Issue #5: Mower Can't Drive Correctly
Unequal tire pressures  will cause the vehicle to pull one way, while uneven terrain might lead it down an off-road path. Moreover, a loose component in the system might be causing it not to steer correctly.
Our professional landscapers recommend you regularly check the tires for proper pressure. Assess for any loose parts such as worn bushings or gears that might be causing it to drive erratically.
Issue #6: Mower Won't Move
This is a common issue in Troy Bilt zero-turn mowers, or even in other products like the John Deere riding mowers brand, that some novice landscapers experience. Reasons such as engaged drive release lever, worn-out mower components, and insufficient hydraulic oil are commonly associated with this issue.
Check the manual to see how to disengage the drive release lever. Replacing worn-out components should be a part of maintaining an efficient mower.
Issue #7: Mower Shakes and Vibrates
Shaking and vibrations are usually due to a dull blade. A loose or damaged engine flywheel can also cause these issues.
If the mower is shaking, stop using it immediately and check for a dull blade. It would be best if you sharpen or look for a blade replacement.
Issue #8: Uneven Cutting
If your riding mower is not giving the consistent cuts it used to, check for the tire pressure. Uneven terrain can also lead to an inconsistent pattern, and damaged or dull blades could also produce uneven cutting.
Make sure the tire pressure is even on all four tires. Check for dulling or damaged blades and have these lawn mower blades regularly sharpened or replaced.
Issue #9: Gas Leaking
You should address a gas leak immediately, especially if you put excessive oil in your mower tank. The most common gas leak causes are loose fuel lines or a damaged fuel tank.
Our professional landscapers recommend tightening any loose fuel lines and checking for holes or cracks in the fuel tank. If there are significant damages, it’s recommended that the experts handle the repairs to avoid further damage to the equipment.
Issue #10: Mower Smoking
If your mower produces a lot of smoke, it might be due to an oil leak or over-filling the oil tank, and it could also be due to damaged piston rings or valves.
Stop using the mower immediately and check for any leaks. Overfilling the oil tank can cause severe damage to your mower. You should remove the lawn mower gas immediately to avoid further complications.
Why won't my Troy Bilt lawn mower stay running?
If your Troy Bilt mower doesn’t stay running, it could be an issue with the spark plug, fuel filter, or air filter. It’s also possible that the carburetor needs to be cleaned, or there is a problem with the fuel tank.
Where is the fuse on a Troy Bilt riding lawn mower?
The fuse on a Troy Bilt riding lawn mower is located under the hood, near the battery.
