Abstract

The blower (1) is used for transport of chaff, hay, green fodder etc. One end wall (2) of the blower housing has two alternatively usable intake openings (3, 4) of which one (3) is arranged at the centre whilst the other (4) is further away from the blower outlet (5). A damper (6) may be movable to close one of the other opening (3, 4). The damper may be swivelably carried on the end wall (2) and have a passage for the material. There may be one oblong intake opening partly coverable by a slidable damper.
