PRODUCTS Driving Center Pivot Irrigation

745-U Gearbox

Designed for heavier overhung loads

Growers typically use the 745 gearbox on systems that feature large diameter pipe, long spans, heavy towers and/or large wheels. It is also recommended for field conditions where there is a potential for wheel ruts, heavy soil and rough terrain. This gearbox comes with special port in the cover to allow lubricating the output bearing with grease for applications where the gearbox is mounted in a non-conventional position.

The UMC® 745 final drive gearbox features a 2.5″ output shaft with larger output bearings capable of handling heavier overhung loads. The 745 also has a reinforced output flange and a gear case housing that is 25% stronger than the standard 740. It is designed for use on center pivots, corners and lateral move/ linear irrigation systems.
