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.

Claims (49)

1. 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.

2. The mower unit of claim 1 , further comprising a rear plate operatively connected to the rear baffle.

3. The mower unit of claim 1 , wherein the plurality of blade chambers comprise three blade chambers, and wherein the plurality of blade assemblies comprise three blade assemblies.

4. The mower unit of claim 1 , wherein each of the plurality of blade assemblies comprises:

a spindle assembly coupled to the housing; and

a cutting blade rotatably connected to the spindle assembly, each cutting blade extending substantially to the edge of its respective blade chamber.

5. The mower unit of claim 1 , wherein the plurality of blade chambers define joining regions in areas where at least one of the plurality of blade chambers intersects with another of the plurality of blade chambers.

6. 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 blade chambers define joining regions in areas where at least one of the plurality of blade chambers intersects with another of the plurality of blade chambers, and wherein those apertures that are closer to the joining regions are larger than those apertures that are away from the joining regions.

7. The mower unit of claim 6 , wherein the plurality of apertures are circular in shape.

8. The mower unit of claim 6 , further comprising a rear plate operatively connected to the rear baffle.

9. The mower unit of claim 6 , wherein the plurality of blade chambers comprise three blade chambers, and wherein the plurality of blade assemblies comprise three blade assemblies.

10. A mower attachment, comprising:

an attachment housing including 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;

a plurality of blade assemblies positioned within the plurality of blade chambers, each of the plurality of blade assemblies including a spindle assembly coupled to the upper surface and a cutting blade rotatably connected to the spindle assembly; 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 attachment housing includes a discharge chute defined therein, and wherein the plurality of apertures are substantially circular in shape and have varying diameters to optimize air flow towards the discharge chute.

11. The mower attachment of claim 10 , wherein the attachment housing includes a discharge chute defined therein.

12. The mower attachment of claim 11 , wherein the plurality of blade assemblies comprises three blade assemblies arranged substantially in a “V” shape.

13. The mower attachment of claim 12 , wherein the leading plate is substantially “V” shaped.

14. The mower attachment of claim 10 , wherein the plurality of blade chambers define joining regions in areas where at least one of the plurality of blade chambers intersects with another of the plurality of blade chambers.

15. A mower attachment, comprising:

an attachment housing including 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;

a plurality of blade assemblies positioned within the plurality of blade chambers, each of the plurality of blade assemblies including a spindle assembly coupled to the upper surface and a cutting blade rotatably connected to the spindle assembly; 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 blade chambers define joining regions in areas where at least one of the plurality of blade chambers intersects with another of the plurality of blade chambers, and wherein those apertures that are closer to the joining regions are larger than those apertures that are away from the joining regions.

16. The mower attachment of claim 15 , wherein the plurality of blade assemblies comprises three blade assemblies arranged substantially in a “V” shape.

17. The mower attachment of claim 16 , wherein the leading plate is substantially “V” shaped.

18. A mower system, comprising:

a vehicle; and

a mower attachment coupled to the vehicle, the mower attachment comprising:

an attachment housing including an upper surface, front and rear baffles extending downwardly from the upper surface, the front and rear baffles shaped to define a plurality of blade chambers therebetween, and a discharge chute for dispelling cut material from the attachment housing;

a plurality of blade assemblies positioned within the plurality of blade chambers, each of the plurality of blade assemblies including a spindle assembly coupled to the upper surface and a cutting blade rotatably connected to the spindle assembly; apd

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 therein,

wherein the plurality of apertures are substantially circular in shape and have varying diameters to optimize air flow towards the discharge chute.

19. The mower system of claim 18 , wherein the mower attachment is removably coupled to the vehicle.

20. The mower system of claim 18 , wherein the leading plate is substantially “V” shaped.

21. The mower system of claim 18 , wherein the plurality of blade chambers define joining regions in areas where at least one of the plurality of blade chambers intersects with another of the plurality of blade chambers, and wherein those apertures that are closer to the joining regions are larger than those apertures that are away from the joining regions.
