775-U-AD™ Gearbox

Designed for extreme overhung loads

The UMC® 775-U-AD™ gearbox is designed for use on center pivots and lateral / linear irrigation systems. It is typically used in conjunction with dual wheel or special aftermarket track and/or wheel assemblies. In some cases it removes the need for a spacer to get clearance from the drive tube/base beam.

The UMC® 775-U-AD™ gearbox features a 3.00″ diameter extended output shaft designed specifically to support extreme overhung loads, heavier spans and/or wider wheels as well as cartridge input seals and enhanced gear material that allows for increased load capacity, reduced gear wear and lower operating temperatures.
