PRODUCTS Driving Center Pivot Irrigation

775-U Gearbox

Designed for extreme overhung loads

Growers typically use this gearbox when faced with the same field conditions where a 745 or 760 would do the job but the overhung load from extremely heavy towers and large/wide wheels warrants the use of a box with a larger diameter output shaft and output bearings. It is an ideal selection where dual wheel or special aftermarket track and/or wheel assemblies are used. In some cases it removes the need of a spacer to get clearance from the drive tube/base beam.

The UMC 775-U final drive gearbox features the same great characteristics as the 740, with the addition of a 3″ output shaft and a cover designed specifically to support extreme overhung loads, heavier spans and/or wider wheels for use on center pivots, and lateral move/ linear irrigation systems.
