Embodiment Construction

[0015] The blower unit 1 shown in FIG. 1 includes a housing 2 in which an internal combustion engine is mounted. The internal combustion engine is usually a two-stroke engine and drives a blower wheel which generates an air flow through a discharge pipe 4. The discharge pipe 4 is configured as a short pipe-shaped stub and terminates at a small spacing above the ground 6. The housing 2 of the blower unit 1 includes a back-carrier plate 7 which is configured as a separate component and is tightly connected to the housing 2. A base section 15 is formed on the back-carrier plate 7 at the end of the plate facing toward the ground 6. The base section 15 extends approximately perpendicularly to the back-carrier plate 7. An operator-controlled unit 8 is provided for operating the blower arrangement 1a which includes a moveable rack 3. The operator-controlled unit 8 includes a throttle lever 9 and a switch 10. The switch 10 can be a selector switch for adjusting different modes of operation ...

CROSS REFERENCE TO RELATED APPLICATION [0001] This application claims priority of German patent application no. 103 59 749.2, filed Dec. 19, 2003, the entire content of which is incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] A known portable blower includes a handle with which the blower can be guided manually. Blowers are also known which can be carried on the back of an operator. Blowers of this kind can be used in many ways because the operator is not dependent upon easily accessible ground such as pathways or the like as is the case in moveable blowers. However, the operator must always carry the blower. This leads to rapid fatigue of the operator. SUMMARY OF THE INVENTION [0003] It is an object of the invention to provide a portable blower of the kind referred to above which can be used in many ways and which reduces fatigue of the operator. [0004] The portable blower arrangement of the invention includes: a blower unit including a housing; a device for gu...
