| Abstract | The invention is directed to an air cushion supported vegetation cutter including a cutter casing housing an impeller for creating the air cushion in conjunction with the casing. An aperture in the casing permits air flow to the impeller and a support structure supports a motor for driving the impeller. The support structure provides a duct for the flow of cooling air over the motor and the duct has cooling air outlets located upstream of the aperture in the casing. This arrangement provides an improved motor cooling arrangement in which the motor cooling air and the air for the impeller interact upstream of the impeller. |
