Abstract: An improved forage blower having a small first stage paddle wheel type impeller or ventilator feeding a large conventionally sized second stage paddle wheel type impeller or ventilator via a short duct for transferring forage from the first stage ventilator to the second stage ventilator, the arrangement being such as to maintain the duct as short as conveniently possible to reduce loss of forage speed from the first stage ventilator to the second stage ventilator. The shafts of both ventilators are spaced apart and parallel, extending horizontally from a main power input for connection with a suitable motor such as the power take off of a farm tractor.
