This deck spindle assembly is an aftermarket replacement for compatible Ariens and Gravely Ikon 42 mower decks. It mounts in the cutting deck, supports the mower blade, and transfers belt drive through the spindle so the blade can cut properly. Built to match OEM This assembly is made to match the original spindle’s fit and function for the deck applications it is intended to replace. The mounting pattern, shaft alignment, and working surfaces are designed for proper blade and pulley positioning without changing the deck setup. Installation Installation is a typical bolt-on spindle replacement using common mower service tools. Remove the deck belt, blade, and pulley as needed, unbolt the old spindle, and install this assembly in the same location; no deck modifications are required when used on a compatible mower. .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; } }
