Abstract
A portable leaf blower comprises a housing having an air inlet and an air outlet port and defines an air outlet port axis. A handle is attached to the housing. A motor is mounted within the housing, with the motor mount having a rotatable drive shaft. A rotatable impeller is mounted on the drive shaft for rotation therewith, and to draw air into the air inlet and to blow the air out of the air outlet port in generally parallel relation to the air outlet port axis. A blower tube has a tube ingress port and a tube egress port, and defines a tube ingress port axis. The blower tube is connectable in supported relation to one of the housing and the handle, such that the tube ingress port is positioned in spaced relation to the air outlet port, with the air outlet port axis being coincident with the tube ingress port axis.
