A lawnmower comprises a deck defining a cutting chamber 5, the deck including an aperture 19 for passage of cut grass from the cutting chamber, a cutter blade 6 rotatable within the cutting chamber about a substantially vertical axis, a grass collection receptacle 13 including a first air permeable region 12b and a first inlet 16 for entry of the cut grass from the cutting chamber, and an air moving device 7 for drawing air from the grass collection receptacle via the first air-permeable region, and for directing the so-drawn air into the cutting chamber. The resultant primary air flow serves to entrain cut grass within the cutting chamber and to convey said entrained grass into the grass collection receptacle via the aperture and the first inlet. A secondary air inlet 17, which is disposed in the region of the first inlet, permits entry of a stream of secondary air into the receptacle. The stream of secondary air serves to complement the primary air flow through the receptacle, and to assist in deflecting the cut grass entrained in the primary air stream into the interior of the receptacle. |
