This is an aftermarket half shaft for compatible Grasshopper mower deck and snowthrower drive applications. It transfers drive power through the assembly so the attached component can operate as intended. Use it when the original shaft is worn, bent, damaged, or no longer holding proper alignment. Built to match OEM This replacement shaft is made to match the original part’s fit and function in the drive system. The shaft is machined for proper seating with the related couplers, bearings, and mounting points, with dimensions intended to follow the factory-style layout. Installation Installation is a straightforward replacement job for a mechanic familiar with mower deck or attachment driveline service. Remove the worn shaft, inspect the surrounding bearings, keys, fasteners, and couplers, then install this part in the same position with no modifications expected. .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; } }
