This aftermarket spindle is a replacement mower deck spindle for compatible Ariens and Gravely 52-inch deck applications. It supports the mower blade and pulley in the deck drive system, letting the blade spin correctly while keeping the cutting assembly aligned. Built to match OEM This spindle is made to match the original-style fit and function for the intended deck. Mounting points and shaft positioning are built to align with the existing deck layout so blade height, pulley location, and belt routing stay where they belong. Installation Installation is a straightforward bolt-up job for a mechanic familiar with mower deck service. Remove the belt, blade, pulley, and spindle hardware, then install the replacement spindle in the original location using standard shop tools; no cutting or welding 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; } }
