ABSTRACT:
The present invention includes mulching apparatus and method for comminuting solid organic vegetation material including a housing having an inlet opening and an outlet opening, a power-driven, rotatable shaft mounted in said housing, a fan blade assembly driven by said shaft for propelling said solid material between said inlet opening and said outlet opening, a flinger assembly of flexible flinger bars rotatably driven by said shaft, each flinger bar comprising a substantially rigid bar member movably affixed pivotally on said flinger assembly and having a substantial inertial mass sufficient for reducing clogging. In one aspect, protective channel means are adapted to reduce clogging of said solid material and form a protective channel for flinger movement through said channel whereby said movably affixed flinger bar member is disposed to stand out radially from said rotatably driven flinger assembly while flexibly traversing through the channel. In one aspect, the present invention includes mulching apparatus and method having a first stage cutter assembly followed by said flinger assembly as a second stage. In one aspect, the present invention includes mulching apparatus and method for comminuting solid landscaping material positioned on a wheeled frame with hitch receiver for attachment to a drive vehicle.
