This comprehensive guide will walk you through the process, from identifying the right belt to installing it securely, ensuring you’re back to mowing in no time.
In essence, replacing a Gravely belt involves disconnecting the mower deck, identifying the old belt, selecting the correct replacement, and installing the new belt, ensuring proper tension. Let’s delve into the specifics!
Identifying the Right Belt
Before you start, it’s crucial to identify the right belt for your Gravely mower. This ensures smooth operation and optimal performance.
1. Understanding Belt Types:
Gravely mowers utilize different belt types depending on the model and attachments. Common types include:
- Drive Belt: Connects the engine to the transmission, powering the mower deck.
- Deck Belt: Connects the transmission to the mower deck, enabling blade rotation.
- Mulching Belt: Used in mulching attachments to enhance the chopping action.
2. Checking the Belt Information:
The belt’s specific information is usually printed on the belt itself, or found in your owner’s manual. Look for details like:
- Length: Measured in inches or centimeters.
- Width: Measured in inches or millimeters.
- Ribs: Number of ribs on the belt.
- Material: Typically rubber or polyurethane.
3. Obtaining a Replacement Belt:
Once you’ve identified the belt type, length, and width, you can purchase a replacement belt from authorized Gravely dealers, online retailers, or local hardware stores.
Disconnecting the Mower Deck
Now, let’s get the mower deck ready for belt replacement.
1. Engage the Parking Brake:
Always engage the parking brake for safety and prevent accidental movement.
2. Disconnect the Spark Plug:
To prevent accidental starting, disconnect the spark plug wire from the spark plug.
3. Raise the Mower Deck:
Use the deck lift lever or hydraulic system to raise the mower deck to its highest position, ensuring clearance for working.
4. Disconnect the Deck Belt:
Locate the deck belt and carefully detach it from its pulleys.
Identifying the Old Belt and Selecting the Replacement
1. Inspect the Old Belt:
Inspect the old belt for signs of wear, cracks, or fraying. These indicate it’s time for replacement.
2. Comparing the Old and New Belt:
Once you’ve acquired the new belt, ensure it matches the old belt’s specifications (length, width, ribs, and material).
Installing the New Belt
1. Positioning the New Belt:
Carefully wrap the new belt around the pulleys on the transmission and mower deck, ensuring it’s positioned correctly.
2. Engaging the Belt:
Gently guide the belt into the grooves of the pulleys, making sure it sits securely.
3. Checking Belt Tension:
After installing the belt, ensure proper tension by pressing down on the deck and checking for deflection. The belt should deflect slightly under pressure but not excessively. Adjust the tensioning system as needed.
Reconnecting the Mower Deck and Finishing Up
1. Lower the Mower Deck:
Lower the mower deck to its operating height.
2. Reconnect the Spark Plug:
Reconnect the spark plug wire to the spark plug.
3. Test the Mower:
Start the engine and engage the mower blades. Listen for any unusual noises or vibrations, indicating a potential issue with belt installation.
Maintenance Tips for Long-Lasting Belt Life
1. Regular Inspection:
Regularly inspect the belts for wear and tear, replacing them promptly when signs of damage appear.
2. Clean the Belt Drive System:
Periodically clean the belt drive system, removing debris that can hinder proper operation.
3. Lubrication:
Refer to your owner’s manual for lubrication recommendations, applying appropriate lubricant to the belt and pulley surfaces for smooth operation.

The correct belt for your Gravely lawn mower will depend on the specific model and application. You can find the correct belt by consulting your owner’s manual or by contacting Gravely customer support. Make sure you get the correct size and length to ensure proper operation and prevent damage to the mower. It’s always a good idea to have a spare belt on hand in case of a breakdown.
How do I know if my Gravely lawn mower needs a new belt?
You can tell if your Gravely lawn mower needs a new belt by looking for signs of wear and tear. A cracked, frayed, or stretched belt is a sure sign that it needs to be replaced. If the belt slips or makes a squealing noise while the mower is running, it’s also a good indication that the belt is worn out. Remember, a worn-out belt can lead to poor performance and potential damage to your mower, so it’s best to replace it as soon as possible.
How do I remove the old belt from my Gravely lawn mower?
To remove the old belt from your Gravely lawn mower, you’ll need to loosen the tension on the belt. This can usually be done by adjusting the idler pulley or by loosening the belt tensioner. Once the tension is released, you can remove the old belt by sliding it off the pulleys. Take care not to damage the belt or the pulleys during this process.
How do I install a new belt on my Gravely lawn mower?
To install a new belt on your Gravely lawn mower, simply reverse the process of removing the old belt. First, slide the new belt onto the pulleys, ensuring it is properly seated in the grooves. Then, tighten the idler pulley or belt tensioner to apply the correct tension. Finally, check that the belt is properly aligned and seated on all pulleys before starting the mower.
How do I check the belt tension on my Gravely lawn mower?
To check the belt tension on your Gravely lawn mower, you can use a simple method. Press down on the belt in the middle of its span. It should deflect about 1/2 inch. If it deflects more than this, the belt is too loose. If it deflects less, the belt is too tight. Adjust the tension as needed using the idler pulley or belt tensioner.
How often should I check the belt tension on my Gravely lawn mower?
You should check the belt tension on your Gravely lawn mower at least once a month, or more frequently if you use the mower often. It’s also a good idea to check the belt tension after any major repairs or adjustments to the mower. A properly tensioned belt will help ensure optimal performance and longevity of your mower.
How do I lubricate the belt on my Gravely lawn mower?
You should not lubricate the belt on your Gravely lawn mower. Lubrication can attract dirt and debris, which can lead to slippage and premature wear. The belt should be clean and dry. If you need to clean the belt, use a dry cloth or brush. Make sure to check the belt for wear and tear after cleaning.
