This is an aftermarket deck spindle assembly for compatible Ariens and Gravely mower decks. It is part of the mower deck blade drive system, supporting the blade and pulley so the blade turns smoothly and stays properly located under the deck. Built to match OEM This spindle is made as a direct replacement for the original deck spindle assembly, with mounting points and shaft layout intended to match the factory setup. The assembly is built to fit the existing deck location and work with the related blade and pulley hardware without changing the deck structure. Installation Installation is a straightforward bolt-on repair for a DIY mechanic with common hand tools. Remove the belt tension, blade, and spindle mounting hardware, then install the replacement spindle in the same position and tighten all hardware to the specifications in your mower service manual. No deck cutting or fabrication should be needed. .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
