Abstract:
1. A multiblade lawn mower, comprising: a mower deck having a top wall, a front wall, a back wall, and at least one side wall defining a downwardly directed interior opening; at least two rotary blades disposed within the downwardly directed interior opening; at least one opening in a wall defining the downwardly directed interior opening adapted to discharge cut grass from the mower deck; a generally circular wraparound baffle adapted to surround each rotary blade and form an independent cutting chamber which does not communicate with any other cutting chamber, wherein each generally circular wraparound baffle has a throat area positioned to direct air flow in a common direction wherein each generally circular wraparound baffle has a sloped wall portion having an arcuate shape, wherein the sloped wall portion is adapted to decrease in height gradually from the height of the generally circular wraparound baffle to an edge terminating on the top wall in the throat area to meter cut grass back into the turf and keep cut grass from recycling in the cutting chamber; said sloped wall portion having a curved wall portion having an arcuate shape, wherein the curved wall portion is adapted to curve inward toward the rotary blade away from the generally circular wraparound baffle to meter cut grass back into the turf and keep cut grass from recycling in the cutting chamber; and a power source operatively connected to the rotary blades to impart rotation to each of the rotary blades.
