ABSTRACT:
The present invention provides a mulching attachment for converting vegetation to mulch. The arrangement includes a base plate, mulching members being adapted to be mounted or attached to the upper surface of the base plate. The arrangement further includes a feed hopper which is attached to the base plate and which is adapted to receive vegetable matter to be converted to mulch. The feed hopper includes at least one feed inlet and an elongate base and feed passage. The feed hopper base is inclined downwardly at an angle relative to ground surface. The feed passage is so formed and mounted relative to the base plate that on operation of mulching members a vibratory moment is imparted therefrom to the feed hopper. The combination of the vibration imparted to the feed passage and the downwardly inclined base of the feed hopper enhance passage of vegetable matter therethrough and inhibit or prevent clogging of vegetable matter as it passes through the feed hopper to be drawn through a mouth of the feed passage by suction generated by operation of the mulching members, to enter a cutting and/or mulching zone of the mulching means and to be thereafter discharged therefrom.
