This is an aftermarket gearbox rebuild kit for compatible Kubota mower decks. It belongs in the deck gearbox assembly and is used to service worn internal drive components so the mower deck can transfer power smoothly again. Built to match OEM The kit is made to match the original-style fit and function of the gearbox components it replaces. Mating surfaces and critical features are produced to seat correctly in the existing gearbox housing without changing the deck setup. Installation Installation requires removing and opening the gearbox, so plan on normal shop tools and careful cleanup before reassembly. No deck modifications are intended; install the kit in the original gearbox location and refill/service the gearbox according to your mower deck manual. .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; } }
