ABSTRACT:
A mobile leaf blower includes a main blower assembly driven by an engine or motor. The blower has a deflector box at the blower outlet with deflector plates which enable the air flow to be either directed laterally and forwardly of the blower unit or to a flexible blower tube attached to the unit. The operator may either cause the air flow to flow through the flexible blower tube or forwardly and laterally of the blower unit along the ground. When not in use, the flexible blower tube can be wound around a hose reel attached to the main handles of the ground blower unit.
