Gravely Idler Arm Kit OEM #58813900

Keep your Gravely Pro-Turn 600 zero-turn mower’s deck belt system operating at peak efficiency with this Genuine OEM Idler Arm Kit (Part #58813900). A factory-authorized service replacement for the Pro-Turn 600 (PT600) series, this kit is precision-engineered to Gravely’s exact specifications — delivering the correct pivot geometry, spring tension, and pulley alignment needed for proper deck belt operation and consistent cutting performance.

Why the Idler Arm Kit Matters:
The idler arm is the pivoting tensioner component that keeps constant, calibrated pressure on your mower deck drive belt. Ensuring the idler arm is correctly positioned is critical to maintaining proper belt tension — a misplaced or worn idler arm can cause belt slippage or premature wear. A bent, cracked, or worn idler arm leads to inconsistent belt tension, belt slipping off pulleys, uneven cutting, and accelerated belt wear. Replacing with the genuine OEM kit restores factory-specified tensioning and protects the entire deck drive system.

Signs Your Idler Arm Kit Needs Replacement:

• Deck drive belt repeatedly slipping or jumping off pulleys
• Uneven or inconsistent cutting across the mowing width
• Excessive belt wear or squealing during engagement
• Visible damage, bending, or wear on the idler arm pivot point
• Loose or missing idler pulley hardware
