The speed reducer has one input for connection to the generator socket and it has one or two outputs depending on the user needs, which are adjusted with potentiometers.

Thanks to the high quality of construction, the reduction is achieved with absolute precision (0,1V). Thus, 1 or 2 different sticks can work, each with independent adjustment, along with the old sticks of the rake harvester, all from the same generator. This means less cost for the user with the best production result in the harvest.
