TNT-U-AD™ Gearbox

Designed for towable center pivots and lateral/linear irrigation systems. Purpose-built for higher performance.

TNT-U-AD™ Gearbox

The UMC® TNT-U-AD™ gearbox is designed for use on towable center pivots and lateral/linear irrigation systems. The gearbox design allows the worm gear to disengage from the bull gear so the output shaft can rotate freely, enabling users to move irrigation systems from one field to another.

The UMC® TNT-U-AD™ gearbox is purpose built for higher performance and longer life. It features a 50:1 gear ratio, a 2.25″ diameter output shaft, large input bearings, cartridge seals and enhanced gear material that allows for increased load capacity, reduced gear wear and lower operating temperatures. It is a direct replacement for its predecessor, the TNT-2-U™.
