The UMC 740-U™ gearbox is a heavy-duty center pivot gearbox engineered for center pivot irrigation systems and lateral/linear irrigation machines. Known throughout the irrigation industry as the trusted 50:1 irrigation gearbox, the UMC® 740-U™ has been the industry standard on many agricultural irrigation systems worldwide for decades.

Designed for demanding farming conditions, the UMC® 740-U™ gearbox is built to handle heavier spans, larger pivot tires, and tough field applications. Its larger input bearings provide greater load capacity than the legacy 725-U™ and Moderate Duty™ gearboxes, making it an ideal replacement gearbox for many center pivot brands and irrigation systems.

This premium irrigation drive gearbox features a 50:1 gear ratio, durable 2.25" steel output shaft, steel worm gear, cast iron bull gear, and cartridge-style input and output seals that help eliminate shaft grooving and reduce oil leaks for longer service life.
