This aftermarket gear box rebuild kit is for the mower deck gearbox on compatible Kubota equipment. It is used when the gearbox needs to be serviced instead of replacing the full assembly, helping restore proper power transfer through the deck drive system. Built to match OEM The parts in this kit are made to match the original-style gearbox service components for fit and function. Machining and sizing are intended to line up with the factory gearbox design, so the rebuilt unit goes back together the way it should without guesswork. Installation Installation requires removing and disassembling the gearbox, so plan on normal shop tools and careful inspection during teardown. No modifications are intended when the kit is used in the correct gearbox; clean the housing, check related components, and reassemble to the service manual procedure. .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; } }
