A fan for a forage harvesting system. The fan has paddles each having a propelling surface enlarged radially and in a front-to-rear direction for propelling air and forage. Spaced triangular shredder blades are mounted not only across the outer end of each paddle, but also aligned along the leading edge of each paddle. The leading edge shredder blades all slant towards the rear of their paddle and radially outwardly along their paddle and assist in chopping forage to varied lengths as forage passes over them.
