The generator with speed reducer operates with 12V-20V or 12V-28V voltage with a 70Α or 100Α dynamo depending on the user needs. It has an electronic voltage reducer with 2 potentiometers for two different sticks, separately from each other. It also has a digital voltmeter for the accurate measurement of voltage and safety of each output separately for its protection. Thanks to the high construction quality, 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.
