This is an aftermarket variable speed pulley for the drive system on compatible riding mowers and lawn tractors. It works with the belt drive to change the effective pulley ratio, helping control ground speed as the operator changes speed settings. Built to match OEM This replacement pulley is made to match the original style, belt path, and mounting arrangement for the specified applications. The sheave profile and overall fit are intended to line up with the existing drive belt and related hardware without changing the drive layout. Installation Installation is typically a straightforward remove-and-replace job for a DIY mechanic with standard hand tools. No modifications are intended when the part is matched to the correct machine; inspect the belt, spring, and related idlers while the pulley is off. .product-description-v2 { font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif; color: #1d1d1d; line-height: 1.55; max-width: 720px; } .product-description-v2 > div { margin-bottom: 18px; } .product-description-v2 h3 { font-size: 16px; font-weight: 700; color: #1d1d1d; margin: 0 0 8px; } .product-description-v2 p { margin: 0; font-size: 15px; } @media (max-width: 768px) { .product-description-v2 { font-size: 15px; } } Show more
