An irrigation gearbox is a device that is used to transmit power from an irrigation system’s main drive shaft to the irrigation system’s pump or other equipment. It typically consists of a set of gears that are enclosed in a housing and is designed to withstand the harsh conditions of an irrigation system, including exposure to water, dirt, and debris.

The gearbox is typically mounted on the irrigation system’s main drive shaft and is connected to the pump or other equipment by a secondary drive shaft. As the main drive shaft turns, the gears in the gearbox rotate, transmitting power to the secondary drive shaft and ultimately to the pump or other equipment.
