Gravely Zero Turn Mower Problems

Gravely is a well-known brand that produces high-quality zero-turn mowers. However, like any other machinery, zero-turn mowers can also face problems that can affect their performance. Gravely zero-turn mowers are no exception to this rule, and it is essential to be aware of the common problems that can arise and their solutions to ensure that your mower operates efficiently.

In this article, we will discuss the common problems that Gravely zero-turn mowers face and their solutions.

Gravely zero turn mowers are popular and reliable machines, but like any piece of equipment, they can experience issues.

Here are some common problems and their solutions:

  1. Engine won’t start: If the engine won’t start, check the battery and make sure it’s fully charged. Check the fuel level and make sure there is enough fuel in the tank. If the fuel is old, drain it and refill with fresh fuel. Also, check the spark plug and air filter to make sure they’re clean and in good condition.
  2. Poor cutting performance: If the mower isn’t cutting well, check the blades to make sure they’re sharp and not damaged. If the blades are dull or damaged, they should be sharpened or replaced. Also, check the cutting height and adjust it if necessary.
  3. Uneven cutting: If the mower is cutting unevenly, check the tire pressure to make sure it’s even on all four tires. Also, check the deck for any damage or obstructions, and make sure it’s level.
  4. Hydrostatic transmission problems: If the mower is having trouble shifting gears or moving forward and backward, check the fluid level in the transmission. If the fluid is low, add more to the appropriate level. If the fluid is dirty or contaminated, it should be changed.
  5. Electrical problems: If the mower’s electrical system isn’t working properly, check the battery and charging system. Make sure all connections are tight and clean. If the problem persists, there may be a faulty component, such as a solenoid or ignition switch, that needs to be replaced.
  6. Belt problems: If the mower’s belts are slipping or breaking, check the tension on the belts and adjust if necessary. Also, check the pulleys for damage or wear and replace if needed.
  7. Steering problems: If the steering is not responding properly, check the steering linkage and make sure all connections are tight and in good condition. If the problem persists, there may be a problem with the steering pump or motor, which will need to be serviced or replaced.

If you’re unable to troubleshoot or fix the problem on your own, it’s best to contact a professional Gravely service technician to diagnose and repair the issue.

  1. Ensure the battery is fully charged and the fuel level is adequate. Drain old fuel and replace with fresh fuel if necessary. Check the spark plug and air filter for cleanliness and damage.
  2. Check the blades for sharpness and damage. Sharpen or replace if necessary. Adjust the cutting height if required.
  3. Check the tire pressure and ensure it is even on all four tires. Inspect the deck for damage or obstructions and ensure it is level.
  4. Check the fluid level in the hydrostatic transmission and add more fluid to the appropriate level. If the fluid is dirty or contaminated, change it.
  5. Check the battery and charging system, ensuring all connections are clean and tight. If the problem persists, replace faulty components like solenoids or ignition switches.
  6. Check the belt tension and adjust if necessary. Inspect the pulleys for damage or wear and replace if required.
  7. Check the steering linkage and ensure all connections are tight and in good condition. If the problem persists, have the steering pump or motor serviced or replaced.


Gravely zero-turn mowers are reliable and efficient machines, but like any other machinery, they can also face problems. Common issues include engine problems, electrical problems, and transmission problems. To solve these problems, it is recommended to replace the fuel filter, drain old fuel and replace it with fresh gasoline, clean or replace the carburetor, check the battery voltage, tighten connections, replace any damaged safety switches, check the transmission fluid levels, replace damaged belts, and replace the clutch if necessary. Regular maintenance and servicing can prevent these problems from occurring and ensure that your Gravely zero-turn mower operates efficiently.
