Agricultural Gearbox Solutions for Combine Harvesters

The perfect interplay makes harvesting machines like combine harvesters or maize headers fascinating machines. This is where AUMA Drives gear units come into play. The adjustable spout of the combine harvester is driven by a worm helical gear unit designed as slewing gear unit. A three-stage gear unit always provides the suitable transmission ratio for the complex technology.

A slewing gear unit is at the heart of the system. The sprout pipe is guided through the opening in the worm wheel, a closed housing protects both splines and bearings. Furthermore, the gear unit can be upgraded with a primary stage gear and motor to a complete drive system as an option.

The integral overload slip clutch serves as important safety feature. Since threshed corn is often transported via sprouts into lorries accompanying the harvesting process. In case of collision, the clutch provision sufficient protection so that the mechanics of the sprout remains intact.
