Total Claims: 10
Claim 1
Independent Claim
197 words
A mowing and mulching apparatus comprising: a. a housing having at least a top surface, said top surface having an aperture; b. a rotatable cutter located beneath said top surface for cutting vegetation; c. a prime mover attached to said housing and having a drive shaft extending through said aperture for rotating said cutter, and; d. a generally cylindrical skirt, attached to said housing, generally concentric with said drive shaft and located between said cutter and the underside of said top surface, said skirt including: i. a first set of mulching blades including a plurality of individual mulching blades arranged around said skirt, each individual mulching blade being inclined downwardly from said skirt relative to the underside of said top surface, and extending radially outwardly from said skirt, and; ii. a second set of mulching blades spaced downwardly from said first set of mulching blades, said second set of mulching blades including a plurality of individual mulching blades arranged around said skirt, the edge of each individual mulching blade furthest from said skirt being inclined at an angle relative to said top surface and extending radially outwardly from said skirt for disrupting the flow of said vegetation.
Claim 2
Dependent Claim
197 words
A mowing and mulching apparatus comprising: a. a housing having at least a top surface, said top surface having an aperture; b. a rotatable cutter located beneath said top surface for cutting vegetation; c. a prime mover attached to said housing and having a drive shaft extending through said aperture for rotating said cutter, and; d. a generally cylindrical skirt, attached to said housing, generally concentric with said drive shaft and located between said cutter and the underside of said top surface, said skirt including: i. a first set of mulching blades including a plurality of individual mulching blades arranged around said skirt, each individual mulching blade being inclined downwardly from said skirt relative to the underside of said top surface, and extending radially outwardly from said skirt, and; ii. a second set of mulching blades spaced downwardly from said first set of mulching blades, said second set of mulching blades including a plurality of individual mulching blades arranged around said skirt, the edge of each individual mulching blade furthest from said skirt being inclined at an angle relative to said top surface and extending radially outwardly from said skirt for disrupting the flow of said vegetation.
