Grab this premium cogged V-belt for just $51.65. This cost-effective option ensures your Gravely mower’s power system operates reliably and effectively.

3. Drive Belt Bolts and Spacers (4)

The drive belt system relies on bolts (3, 9, 13, 20, 24, 28, 31, 34, 36, 38) and spacers (4) for strong connections. These fasteners are essential for assembling idler pivot arms, bearing pedestals, and pulleys, ensuring system integrity.

Bolts commonly slot into existing holes and are secured using nuts. These fasteners, along with spacers, provide robust support. They also ensure precise component alignment and consistent spacing.

These parts maintain correct belt tightness and reduce friction. Each bolt costs from $1.05 to $6.55. The spacer’s price is $10.95.

4. Cap Idlers (6)

Cap idlers, usually six, are carefully placed near the mower deck’s pulleys and drive belt. They mainly support and guide the drive belt, ensuring proper direction.

Gravely Cap idlers act as pulleys. They guarantee correct drive belt positioning and tension. Get yours today for just $14.25.

5. Idler Pivot Arms (7, 18, 32)

The mower deck features idler pivot arms (7, 18, 32). These arms serve as pivot points for the cap idlers. They are directly linked to the bearing pedestals.

These self-adjusting cap idlers automatically reposition themselves. They utilize pivoting arms to respond to changes in drive belt tension. The latest versions are priced from $41.95 to $83.79.

6. Bearing Pedestal (8)

Gravely mower decks in 2025 feature bearing pedestals (8). These pedestals firmly hold cap idlers and idler pivot arms. They are crucial for ensuring smooth and reliable mower operation.

These parts typically connect to your Gravely mower deck with bolts and washers. The estimated cost is approximately $73.45.

7. Extension Springs (10, 29)

Gravely mower decks utilize extension springs (10, 29) positioned close to the idlers and arms. These springs link the deck to other components. They are crucial for maintaining proper drive belt engagement with the pulleys. They achieve this by applying the necessary tension, ensuring optimal performance in 2025.

Select from two extension spring choices. Opt for the premium spring at $32.95, or the standard option for $25.25. Both ensure dependable operation.

8. Pulleys (22, 23, 25)

Pulleys (22, 23, 35) are critical components. They sit on the engine’s driving shaft, the cutting blade shaft, and throughout the drive belt’s path. These pulleys feature grooved surfaces. Their rotation provides support and direction for the Gravely drive belt, ensuring efficient operation.

These pulleys are essential. They ensure the drive belt stays firmly in place, maximizing performance. Their size and design also affect blade speed and torque, boosting efficiency.

In 2025, anticipate spending from $65.95 to $92.35 for these enhanced pulleys.

9. Assembly PTO Idler (30)

The PTO Idler Assembly (30) is crucial for maintaining proper drive belt tension during PTO operation. Locate it near the PTO assembly itself.

This idler assembly, crucial for Gravely mowers, includes a pulley or roller, a supporting bracket, and a secure mounting system. It’s designed to maintain proper tension on the drive belt, ensuring consistent engagement with the PTO pulleys.

This mechanism lets you precisely adjust the Gravely drive belt’s tightness. Get yours today for just $69.83.

10. Washers (11, 14, 21, 27)

Washers (11, 14, 21, 27) are vital parts in Gravely mowers. They are carefully positioned to distribute pressure. This ensures easy movement between bolts, nuts, and other components. This also minimizes damage and extends lifespan.

These washers act as spacers. They reduce friction and ensure smooth hardware movement. Expect prices between $0.50 and $3.91.

11. Nut couplings (33)

Nut couplings (33) are commonly employed to secure pulleys, idler arms, and bearing pedestals in place. They offer a reliable fastening mechanism when threaded onto bolts or shafts.

These crucial nut couplings are key for a dependable Gravely drive belt setup. Secure tightening guarantees components remain steadfast. This stops any undesired shifting or detachment while in use. Purchase yours today for only $3.58.

What are Some Common Problems of Damaged Gravely Drive Belt Components?

Common problems associated with damaged or failing Gravely drive belts include:

Loss of Tension: Worn or damaged idlers, pulleys, or tension springs can result in a loose drive belt, causing inefficient power transfer and reduced cutting performance.

Belt Slippage: Damaged pulleys or idlers may fail to maintain proper belt tension, leading to belt slippage. This can result in uneven cutting and poor traction.

Excessive Wear: Over time, damaged components can lead to increased wear on the drive belt itself, shortening its lifespan and requiring more frequent replacements.

Inconsistent Cutting Height: Uneven tension caused by damaged components can result in inconsistent cutting heights, leaving an uneven lawn surface.

Belt Breakage: Excessive stress on a damaged drive belt can lead to breakage, halting mower operation until the belt is replaced.

Reduced Blade Speed: Damaged pulleys or idlers can affect the engagement of the drive belt with the mower blades, leading to reduced blade speed and diminished cutting efficiency.

Excessive Vibrations: Misaligned or damaged components can cause the mower deck to vibrate excessively, leading to discomfort for the operator and potentially further damage to the mower.

Noisy Operation: Damaged components may produce unusual noises during operation, indicating the need for inspection and replacement.

Safety Concerns: Faulty drive belt components can pose safety hazards, such as belt ejection or damage to nearby parts, which could lead to accidents or injuries.

Premature Belt Replacement: Continual use of damaged components can cause the drive belt to wear out faster, leading to frequent and costly replacements.

Keep your Gravely equipment running smoothly and safely. Regularly service and promptly replace any worn or damaged drive belt components.
