Abstract:
A mowing and mulching system for mowers comprising:a) a cover; b) a plurality of knives working as a sickle disposed within said cover, said knives comprising: i) a knife blade part having baffle surfaces set slanted vs. a plane of rotation of said plurality of knives; ii) a hub part; iii) a plurality of cutting edges extending from said knife blade part to said hub part, said cutting edges being contoured in a leading edge zone forming an outer cutting edge segment adjoined by a center blade segment which ascends beyond a plane of said hub part and descending into said plane of said hub part wherein said knife blade part has a trailing longitudinal edge that extends in or above said plane of said hub part; c) a driving shaft disposed within said cover; d) at least one turbo disk disposed adjacent to said hub part and coupled to said driving shaft above said plane of rotation of said plurality of knives, said turbo disk being in the form of a receiving dish and a plurality of baffle plates coupled to said receiving dish, wherein said turbo disk extends over said hub part towards said center cutting edge segment; e) a plurality of mowing and mulching mechanisms formed by said plurality of knives and said at least one turbo disk arranged adjacent to each other staggered with respect to a cutting advance of said mowing and mulching mechanism; and f) a turbine formed as a bucket wheel disposed inside said cover offset from and adjacent to said mowing and mulching mechanisms above a plane of said mowing and mulching mechanisms wherein said turbine rotates in a same direction of said mowing and mulching mechanisms.
