Let’s explore seven common Gravely zero-turn mower problems and discover how to fix Gravely mowers effectively to keep your lawn perfect!

1. Mower Won't Start

Check the Battery

Start-up issues often link to a dead battery. Loose or corroded cables could be the culprits. Tighten connections and inspect for corrosion. Use a multimeter to test battery voltage; it should read around 12.6 volts when fully charged. If needed, charge or replace it.

Inspect the Fuel System

Old fuel can clog the system, hindering starts. Drain old gas and refill with fresh, ethanol-free fuel. Clean or replace the fuel filter regularly to prevent clogs that decrease engine performance.

2. Uneven Cutting

Level the Deck

An unlevel deck results in an unsightly lawn. Place your mower on level ground, and adjust the deck using a level tool. Each model varies, so consult your manual for specifics.

Sharpen the Blades

Dull blades tear grass, making it susceptible to disease. Sharpen your lawn mower blades the right way at least twice a season for a healthy, clean cut. Always disconnect the spark plug before performing blade maintenance for safety.

3. Mower Vibrates Excessively

Check for Loose Bolts

Vibrations cause bolts to loosen. Regularly inspect and tighten all fasteners. Replace any missing bolts to prevent operational issues.

Inspect the Blades and Spindles

Bent or damaged blades and spindles cause vibration. Regularly check for damage, and replace components as needed. A smooth-running mower depends on well-maintained parts. Learn how to diagnose and fix lawn mower vibration problems with this detailed guide.

4. Mower Smokes

Inspect the Oil

Overfilled oil often results in exhaust smoke. Use a dipstick to check levels. Drain excess oil, adhering to your mower’s oil grade specifications. Regular oil changes —about every 50 hours of use—extend engine life.

Check the Air Filter

A clogged air filter reduces engine efficiency. Regular cleaning or replacing enhances performance and prevents smoking. Clean your filter by tapping out dirt or washing it with soapy water.

5. Slow or Stuck Wheels

Check Hydraulic Fluid

Hydraulic fluid levels impact speed and wheel function. Ensure correct fluid levels, and check for leaks. Refill and repair as necessary to maintain zero-turn capabilities.

Inspect the Tires

Flat or improperly inflated tires slow your mower. Check pressure with a gauge, and inflate according to the specifications. Tire maintenance prevents uneven cuts and ensures smooth operation.

6. Belt Issues

Examine the Belts

Worn belts slip and cause inefficiencies. Check for fraying and replace as required. Belts should be tightly aligned to pulleys to prevent wear.

Check Belt Alignment

Poor alignment leads to belt wear. Ensure proper alignment and tension following your mower's manual instructions. Listen for squealing sounds as an indicator of misalignment.

7. Mower Stalls Mid-Mow

Look at the Carburetor

Carburetor issues often trigger stalling. Routine cleaning mitigates dirt buildup. Use a carburetor cleaner and inspect for blockages. Consistent maintenance ensures smooth mowing.

Inspect the Fuel Lines

Clogged or damaged fuel lines affect engine operation. Check for blockages or cracks. Clean and replace lines to ensure steady fuel flow.
