The most advanced gearbox of its class

755-U-AD™ Gearbox

The patented UMC® 755-U-AD™ gearbox is designed for use on center pivots and lateral / linear irrigation systems. It is our most technologically advanced standard size gearbox with a 50:1 gear ratio and it is a direct replacement for the 740-U-AD™.

The patented UMC® 755-U-AD™ gearbox is built with enhanced gear materials for greater load capacity, reduced gear wear, and lower operating temperatures. It also features an internal diaphragm that minimizes internal pressure, extending seal life and further reducing the risk of oil leaks.
