This aftermarket mower deck PTO driveshaft is a replacement part for compatible John Deere mower deck setups. It connects the tractor PTO driveline to the mower deck so power can be delivered to the cutting deck during operation. If the original shaft is worn, bent, or loose at the joints, this part restores the driveline connection. Built to match OEM This driveshaft is built as a faithful aftermarket replacement to match the original-style fit and function. The shaft, yoke layout, and connection points are made to line up with the existing mower deck PTO driveline without changing the surrounding components. Installation Installation is a direct replacement job when the part is correct for your machine. Use normal shop tools, shut the tractor down, remove the key, and make sure the PTO is fully disengaged before working around the driveline. No cutting, welding, or custom modification is intended. .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; } }
