Abstract
The invention provides a mulching arrangement for a rotary, motor lawnmower. The attachment comprises a base plate on which a motor mower can be removably mounted. A feed hopper is provided for receiving vegetable matter to be comminuted, the feed hopper being provided with one or more feed inlets. The feed hopper includes a substantially planar base, downwardly angled relative to the ground surface and also includes a feed passage through which vegetable matter passes before entering into a cutting region of the lawnmower to be comminuted into mulch and discharged from the mower. The feed passage of the feed hopper is so formed and attached or mounted to the base plate, that on operation thereof a vibratory moment is imparted from the lawnmower to the base of the feed hopper and the feed passage. This vibration combined with the downwardly angled and inclined base of the feed hopper relative to the ground surface substantially enhances passage of vegetable matter through the feed hopper and at least inhibits the clogging of vegetable matter therewithin.
