Abstract
A portable, hand-held snow thrower comprising a power unit and an attachment removably securable to the power unit. The attachment includes an impeller having a first pulley and a flexible drive shaft. A first end of the drive shaft is connected to the power unit, and a second end of the drive shaft is drivably connected to a second pulley lying substantially in a plane with the first pulley. A lower portion of the drive shaft is curved and extends through an impeller housing. The second pulley is operably connected to the first pulley to provide a gear ratio therebetween resulting in a desired rotational speed of the impeller.
