Abstract
A cross flow rotary type mower has a rotor (21) mounted for rotation about a vertical axis. A housing having an upper wall (10) and side walls (29, 30, 31) surrounds the rotor to form a cross-flow blower. A portion (37) of the upper wall is expanded axially of the rotor to provide an axially extending vortex chamber (36) within the housing. The blower has an air inlet region (26) and an air outlet region (18) where the outlet region has a greater vertical height then the inlet region.
