A motor-powered mulching mower and edger apparatus (20) with dual rotary mower blades (33,35), a mower deck (21) and a side-mounted edger attachment (75) adapted by a clutch mechanism (110,111) for simultaneous operation therewith. An adjustable mulching control valve (60) mounted at the inlet of a discharge chute (39) from the deck (21) allows variation of the proportions of mulching to clippings bagging in the range of zero to one hundred percent during mower operation. The dual rotary blades (33,35) are mounted in vertically spaced relation and select leading-angle trailing-angle relationship and are cooperable with an internal deck-mounted air stream deflector (68) for deflecting multiple cuttings of grass clippings in an inwardly directed spiral path such that after the initial cutting, each of the clippings is disposed to at least two more cuttings to produce a finer mulch. The edger (75) is provided with an edger blade guard (109) which can be adjustably positioned to deflect and guide edger-produced clippings to the interior of the mower deck (21) in an air stream which enforced the air stream generated by the mower blades (33,35) and enhances vacuuming capability of the apparatus (20). Swivel-mounted castor wheels (25,26) at the front of the mower deck (21) and an off-set of the front wheel (25) and real wheel (27) nearest the edger (75) towards the center line of the apparatus (20) facilitates the operation of the edger (75) in a curved path.
