Abstract
A cutting chamber for a mower deck blade is comprised of first and second adjoining skirt members of differing lengths to provide for a lifting air stream at the front of the chamber and a discharging air stream at the rear of the chamber. As a result, cut material can be recut in a mulching action and then easily discharged to the rear of the deck.
Claims7
A mower deck of one-piece construction, the deck having a housing with a top, front and side surfaces depending therefrom, with the rear of the deck being substantially free of obstruction so as to permit discharge of material therefrom,
- a cutting blade drivingly supported by the deck to rotate in a generally circular and horizontal plane, the improvement comprising:
- a cylindrical chamber surrounding the blade and depending from the top surface of the deck, said chamber comprised of first and second skirt portions, the first skirt portion enclosing the forward and side portions of the chanter and extending between the top surface of the deck to approximately the plane of the blade,
- and the second skirt portion being operatively joined with the first portion and extending from the top surface of the deck downwardly substantially less than the distance to said plane, the first and second skirt portions being adjacent, and in tiered relationship to one another.
