Abstract
Abstract This disclosure relates to lawn care apparatus, and more particularly to a combination mower/edger. Both units are driven by a single motor and can be operated either singly or in combination. The edger portion is simplified by being driven by a flexible shaft and is adapted to be positioned on either side of the mower, depending upon the convenience of the operator. Moreover, the edger may be tilted relative to the mower for a desired angle of edging, or to compensate for the slope of the ground.
