PRODUCTS Driving Center Pivot Irrigation

740-U™ Gearbox

The industry standard 50:1 gearbox

The UMC® 740-U™ gearbox is designed for use on center pivots and lateral / linear irrigation systems. It has been the industry standard 50:1 gearbox used on many center pivot and lateral / linear irrigation systems globally for decades. It is capable of handling most field conditions and applications and its larger input bearings enable it to handle more load than the 725-U™ and Moderate Duty™ gearboxes and in turn support heavier spans and larger wheels.

Part Number Ratio

The UMC® 740-U™ gearbox features a 50:1 gear ratio, a 2.25″ diameter output shaft, large input bearings, a steel worm gear, a cast iron bull gear and cartridge input and output seals that eliminate shaft grooving and reduce oil leaks.
