This is an aftermarket blade sheave deck pulley for compatible Exmark mower decks. It is part of the deck belt and blade drive system, helping route belt power to the blade spindle so the deck can cut properly. Built to match OEM This pulley is made as a direct replacement for the original deck pulley position. The shape, belt contact surface, and mounting fit are intended to match the factory-style setup so belt alignment and deck operation stay correct. Installation Installation is a straightforward deck service job for most DIY mechanics with basic hand tools. Remove belt tension, replace the worn pulley, and reinstall the belt using the existing deck routing; no cutting or modifications are intended. .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; } }
