Step-by-Step Guide to Replacing the Belt
1. Prepare Your Mower
Before beginning any maintenance task, ensure that your mower is on a flat surface and that the engine is turned off. Engage the parking brake for added safety.
Steps to Prepare:
- Disconnect the spark plug wire to prevent accidental starting.
- Remove the key from the ignition.
2. Access the Belt
To replace the belt, you will need to access the mower deck. The process may vary slightly depending on the specific Gravely model you own, so consult your owner’s manual for precise instructions.
Steps to Access the Belt:
- Raise the mower deck to its highest position using the deck lift lever.
- Secure the deck in place if necessary.
- Remove any guards or covers that obstruct access to the belt.
3. Remove the Old Belt
With access to the belt, it’s time to remove the old one. Carefully note the routing of the belt for easier installation of the new belt.
Steps to Remove the Old Belt:
- Identify the tensioner pulley and use a wrench to relieve the tension on the belt. This may involve turning the tensioner pulley in the opposite direction.
- Once the tension is released, carefully slide the belt off the pulleys.
- Take note of how the belt is routed around the pulleys; it’s helpful to take pictures for reference.
4. Install the New Belt
Now that the old belt is removed, you can install the new one. Ensure that you have the correct belt for your specific model.
Steps to Install the New Belt:

- Make sure the belt is seated properly in the grooves of each pulley.
- Reattach the belt to the tensioner pulley, ensuring it’s tight but not overly strained.
5. Check Belt Tension
Once the new belt is installed, it’s crucial to check its tension. Proper tension is necessary for efficient operation and to prevent slipping.
Steps to Check Tension:
- With the tensioner pulley still engaged, inspect the belt to ensure it’s tight against the pulleys.
- If the belt appears loose, adjust the tensioner according to the specifications outlined in your owner’s manual.
6. Reassemble the Mower
After the belt is securely installed and properly tensioned, it’s time to reassemble any components you removed.
Steps to Reassemble:
- Reattach any guards or covers that were removed to access the belt.
- Lower the mower deck back to its normal operating position.
- Reconnect the spark plug wire and insert the key back into the ignition.
7. Test the Mower
Before putting the mower back into regular use, it’s essential to test it to ensure everything is functioning correctly.
Steps to Test:
- Start the mower and let it idle for a minute.
- Engage the mower blades and check for smooth operation.
- Drive the mower forward and backward to ensure the drive belt is functioning properly.
