Zero-Turn Mower Not Running Right? Here's What to Do — And Where to Get It Fixed in Farmington, MO
Zero-turn mowers are the workhorses of both residential lawns and professional landscape operations. They’re fast, maneuverable, and built for efficiency — but when something goes wrong, they can sideline an entire operation.
If your zero-turn is showing any of the signs listed below, don’t wait. Catching a problem early almost always means a faster, less expensive repair. And if you’re in the Farmington, Missouri area, Revolution Landscape Equipment & Supply is your local go-to for zero-turn mower service and repair.
5 Signs Your Zero-Turn Mower Needs Service
It won’t start or cranks but doesn’t fire— Could be a carburetor issue, fuel problem, or ignition fault. Don’t keep cranking; bring it in before you cause further damage.
Uneven cutting / scalping— If your deck isn’t cutting evenly, the blades may be dull, bent, or the deck may be out of level. This is a common issue that affects cut quality significantly.
Loss of power under load— If the engine bogs down when you hit taller grass, this is often a carburetor or air filter issue, but could also point to engine wear.
One side not driving / pulling to one side— Hydrostatic transmission issues can develop gradually. Ignoring them usually leads to more expensive repairs later.
Excessive vibration or unusual noise— Vibration often signals blade or spindle issues. Unusual knocking sounds can indicate engine problems that need immediate attention.

DIY vs. Professional Repair: When to Call Us
Some things you can handle yourself: replacing an air filter, cleaning a clogged deck, or sharpening blades if you have the right tools. But these are the situations where professional service pays off:
Hydrostatic transmission repairs— these are complex and can be made worse by DIY attempts
Carburetor rebuilds— small parts, precise calibration
Electrical diagnosis— safety switch faults and wiring issues require proper diagnostic tools
Spindle replacement— incorrect installation can damage the deck
