Engine Won’t Start
Encountering an engine that won’t start on your Gravely Zero Turn can be frustrating. There are a few common issues that you can check to get it running again. Follow these simple steps to troubleshoot and resolve the problem.
Check Fuel Supply
First, ensure there is enough fuel in the tank. Low fuel levels can prevent the engine from starting. Verify that the fuel valve is open. Sometimes, debris can clog the fuel line. Inspect the fuel line for any blockages or kinks.
Inspect Spark Plugs
Next, examine the spark plugs. Faulty spark plugs can stop the engine from starting. Remove the spark plugs and check for dirt or wear. Clean or replace them if necessary. Make sure the spark plug wires are securely connected.
Battery Issues
A weak or dead battery can also cause starting problems. Check the battery terminals for corrosion. Clean them if needed. Use a multimeter to test the battery voltage. Charge or replace the battery if it is not providing enough power.

Mower Deck Problems
Mower deck problems can disrupt the performance of your Gravely zero turn mower. Addressing these issues promptly ensures a smooth, efficient mowing experience. Let’s explore some common mower deck problems and their solutions.
Uneven Cutting
Uneven cutting can leave your lawn looking patchy. This issue often results from an improperly leveled deck or worn blades. First, check if the mower deck is level. Adjust as necessary to ensure even cutting. Next, inspect the blades. Replace them if they are dull or damaged. Regular maintenance helps prevent uneven cuts.
Deck Belt Issues
A malfunctioning deck belt can halt mowing operations. Common signs of deck belt issues include squealing sounds or the belt slipping off. Inspect the belt for wear and tear. Replace it if it appears cracked or frayed. Ensure the belt is correctly tensioned to avoid future problems.
Blades Not Engaging
Blades not engaging can be frustrating. This problem may stem from electrical issues or a faulty clutch. First, check the PTO switch. Ensure it is in the correct position. Next, inspect the wiring and connections for any damage. If the problem persists, the clutch may need replacing. Consult your mower’s manual for specific instructions.
Hydraulic System Issues
The hydraulic system in your Gravely Zero Turn mower is crucial for smooth operation. Problems can cause your mower to malfunction or stop working altogether. Understanding the common issues can help you troubleshoot and fix them quickly.
Low Hydraulic Fluid
Low hydraulic fluid is one of the most common issues. It can cause the hydraulic system to fail. Here are some signs of low hydraulic fluid:
- Slow response time
- Noisy operation
- Poor mower performance
To check the hydraulic fluid level:
- Park your mower on a flat surface.
- Locate the hydraulic fluid reservoir.
- Check the fluid level using the dipstick.
- Add hydraulic fluid if necessary.
Always use the recommended hydraulic fluid for your mower.
Hydraulic Pump Problems
Hydraulic pump issues can also cause your mower to malfunction. Common problems include:
- Pump not generating enough pressure
- Strange noises from the pump
- Pump overheating
To troubleshoot hydraulic pump problems:
- Check for any blockages in the system.
- Ensure the pump is receiving enough fluid.
- Inspect the pump for any visible damage.
If the pump is damaged, it may need to be replaced.
Leaks And Seal Checks
Leaks in the hydraulic system can lead to fluid loss and system failure. Common leak points include:
- Hydraulic hoses
- Fittings and connections
- Seals and gaskets
To check for leaks:
- Inspect all hoses and connections.
- Look for signs of fluid leakage.
- Tighten any loose fittings.
- Replace damaged hoses or seals.
Regularly check for leaks to ensure your hydraulic system remains in good condition.
Steering And Maneuverability
Steering and maneuverability are crucial for a smooth operation of your Gravely Zero Turn mower. Understanding how to troubleshoot these aspects can save you time and effort. This section will guide you through common issues and their solutions.
Steering Lever Calibration
First, check the steering lever calibration. Misaligned levers can cause uneven steering. Ensure both levers are even when in the neutral position. Adjust them if necessary. Follow the manual for specific calibration steps. Proper calibration ensures smooth and responsive steering.
Tire Pressure Check
Next, inspect the tire pressure. Unequal tire pressure affects maneuverability. Use a tire gauge to check each tire. Inflate or deflate to match the recommended PSI. Consistent tire pressure aids in smooth and balanced steering. It also prevents unnecessary wear on the tires.
Hydraulic Drive Issues
Lastly, examine the hydraulic drive system. Low hydraulic fluid can hinder performance. Check fluid levels regularly. Refill if they are low. Look for any leaks or damaged hoses. Ensure filters are clean and not clogged. Proper maintenance of the hydraulic system is essential for effective maneuverability.
Electrical Problems
Electrical problems can be a common issue for Gravely zero turn mowers. These issues can cause the mower to stop working or not start at all. Identifying the root cause of the electrical problem is crucial for getting your mower back in action. Here are some common electrical issues and their troubleshooting steps.
Blown Fuses
Blown fuses are a frequent cause of electrical problems. If your Gravely zero turn mower isn’t starting, check the fuses. A blown fuse can stop the electrical circuit, preventing the mower from working. Replace any blown fuses with the correct type and rating for your mower.
Faulty Ignition Switch
A faulty ignition switch can also cause your mower to fail. If the ignition switch is not working, the engine won’t start. Check the switch for any signs of damage or wear. Replacing a faulty ignition switch can often solve the problem.
Wiring Inspections
Wiring issues can lead to various electrical problems. Inspect the wiring harness for any loose or damaged wires. Ensure all connections are secure and free of corrosion. Fixing any wiring issues can help restore the electrical system’s functionality.
Overheating Issues
Overheating is a common problem for Gravely Zero Turn mowers. It can reduce the mower’s efficiency and lifespan. Understanding the causes and solutions is key to keeping your mower in top shape.
Clean Air Filters
Dirty air filters restrict airflow to the engine. This causes it to overheat. Check the air filters regularly. Clean or replace them if they are dirty. This ensures proper airflow and helps prevent overheating.
Inspect Cooling Fins
Cooling fins help dissipate heat from the engine. Dirt and debris can clog them. Inspect the cooling fins regularly. Use a brush to clean any buildup. This helps maintain proper engine temperature.
Check Coolant Levels
Low coolant levels can cause the engine to overheat. Check the coolant levels before each use. Top up if necessary. Ensure there are no leaks in the system. This keeps the engine running cool.
Routine Maintenance Tips
Keeping your Gravely zero turn mower in top shape is crucial. Regular maintenance helps avoid unexpected breakdowns and prolongs the life of your machine. Here are some routine maintenance tips to keep your mower running smoothly.
Regular Oil Changes
Changing the oil in your Gravely mower is essential. Fresh oil ensures the engine runs efficiently. Check the oil level before each use. Replace the oil every 50 hours of operation or at least once a season. Use the oil type recommended in the manual.
Blade Sharpening
Sharp blades are crucial for a clean cut. Dull blades tear the grass, causing damage. Check and sharpen the blades after 25 hours of use. Use a proper blade sharpening tool. Always wear gloves to protect your hands.
Seasonal Storage Preparation
Preparing your mower for storage prevents damage. Clean the mower thoroughly to remove grass clippings and dirt. Drain the fuel tank or add a fuel stabilizer. Store the mower in a dry place. Cover it to protect from dust and moisture.
