This is an aftermarket left spindle for compatible John Deere, Scotts, and Sabre mower deck applications. The spindle is part of the deck cutting system and supports the blade drive position so the deck can cut properly and run true. Built to match OEM This replacement spindle is made to match the original part’s fit and function, including the mounting layout and working position in the deck. It is intended to line up with the existing deck hardware and blade drive components without changing the deck setup. Installation Installation is a typical bolt-on mower deck repair for a DIY mechanic with basic hand tools. Remove the belt and blade, unbolt the worn spindle, and install this replacement in the same left-side position; no deck modifications should be needed when used on the correct application. .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; } }
