UMC 765-UV-AD Gearbox

The UMC 765-UV-AD Gearbox is a heavy-duty 52:1 gearbox designed for center pivots and lateral/linear irrigation systems operating in demanding conditions. It is built for applications such as corner systems, lateral carts, heavy towers, high annual operating hours, and extreme field conditions.

The 765-UV-AD features a 2.50-inch extended steel output shaft, 9-bolt mounting pattern, large output bearings, and UMC's vented internal diaphragm system to help minimize internal pressure buildup and reduce the risk of oil leaks. It can also serve as a direct replacement in applications using 52:1 gearboxes as standard equipment.
