Abstract
A mower attachment comprising an attachment housing and a plurality of blade assemblies. The attachment housing includes an upper surface and front and rear baffles extending downwardly from the upper surface, the front and rear baffles shaped to define a plurality of blade chambers therebetween. The plurality of blade assemblies are positioned within the plurality of blade chambers. A leading plate is operatively connected to the housing and extends away from the plurality of blade chambers. The leading plate includes a plurality of apertures on a top side thereof.
Claims21
A mower unit for cutting material on a surface, comprising:
- a housing including a discharge chute defined therein for discharging material;
- a plurality of blade assemblies operatively connected to the housing for rotation about an axis substantially perpendicular to the ground;
- a front baffle operatively connected to the underside of the housing;
- a rear baffle operatively connected to the underside of the housing, the front baffle and the rear baffle cooperating to define a plurality of blade chambers substantially surrounding the plurality of blade assemblies;
- and
- a leading plate operatively connected to the front baffle and extending away from the plurality of blade chambers, the leading plate including a plurality of apertures,
- wherein the plurality of apertures are circular in shape, and wherein the plurality of apertures have varying diameters to optimize air flow towards the discharge chute.
