The Mulching technology finely shreds the grass cuttings and deposits them on the ground as a natural lawn fertiliser. The original Mulching kit for garden tractors includes a mulching plug, which blocks the entrance to the collection tunnel and special blades to maximise mulching performance. This accessory is perfect during Spring and Summer, to be used with all garden tractors with a 98 cm cutting deck. The mulching blades should be installed by an authorised dealer.
