Abstract

An improved spreader assembly adapted to be mounted on a vehicle having a tailgate and a bumper. The improved spreader assembly includes a hopper and a retaining arrangement. The hopper has an upper section and a bottom section. The bottom section has a base surface adapted to at least partially rest on a top surface of the bumper. The retaining arrangement includes a band that fits at least about a portion of a front face of the upper section of the hopper. One end of the band is adapted to connect to the vehicle to maintain at least a portion of a back face of the upper section at least closely adjacent to the tailgate of the vehicle.

Claims (41)

1. An improved spreader for spreading particulate material comprising a hopper having an upper section and a bottom section, said bottom section having a lower material discharge chamber terminating in a lower discharge opening; a broadcast spreader positioned beneath said discharge opening; a motor to rotate at least a portion of said broadcast spreader; a retaining band that at least partially fits about a front face of said upper section; and a bumper post extending downwardly from said bottom section, said bumper post at least partially adapted to at least partially extend into a hitch ball hole in a bumper of a vehicle.

2. The improvement as defined in claim 1 , wherein said retaining band is at least partially flexible and releasably connectable to said vehicle, said retaining band adapted to draw said upper section of said hopper toward a tailgate of the vehicle.

3. The improvement as defined in claim 1 , wherein said front face of said upper section includes a band retainer adapted to at least partially retain said retaining band on said front face.

4. The improvement as defined in claim 1 , including a band tensioner adapted to at least partially tighten said retaining band.

5. The improvement as defined in claim 1 , wherein said front face of said upper section includes an arcuate surface.

6. The improvement as defined in claim 1 , including a vibrating device connected to said hopper.

7. The improvement as defined in claim 1 , wherein said broadcast spreader includes a motor guard that at least partially encapsulates said motor.

8. The improvement as defined in claim 1 , wherein said upper section includes a fill opening in a top surface of said upper section.

9. The improvement as defined in claim 8 , wherein said fill opening is at least partially closed by a removable cap.

10. The improvement as defined in claim 1 , wherein said hopper is a plastic molded unit.

11. The improvement as defined in claim 1 , wherein said bottom and upper sections include multiple wall layers.

12. The improvement as defined in claim 1 , including a screw mechanism adapted to draw particulate material through said lower discharge opening.

13. The improvement as defined in claim 1 , wherein said bottom section includes a gripping surface adapted to at least partially maintain at least a portion of said bottom section on a top surface of said bumper.

14. The improvement as defined in claim 1 , wherein said upper section includes a viewing opening.

15. The improvement as defined in claim 1 , including at least one hook attached to said retaining band and adapted to connect to a tailgate strike pin of said vehicle.

16. An improved spreader for spreading particulate material comprising a hopper having an upper section and a bottom section, said bottom section having a lower material discharge chamber terminating in a lower discharge opening and a gripping surface adapted to at least partially maintain at least a portion of said bottom section on a top surface of a bumper of a vehicle; a broadcast spreader positioned beneath said discharge opening; a motor to rotate at least a portion of said broadcast spreader; and a retaining band that at least partially fits about a front face of said upper section.

17. The improvement as defined in claim 16 , wherein said front face of said upper section includes a band retainer adapted to at least partially retain said retaining band on said front face.

18. The improvement as defined in claim 16 , including a band tensioner adapted to at least partially tighten said retaining band.

19. The improvement as defined in claim 16 , wherein said front face of said upper section includes an arcuate surface.

20. The improvement as defined in claim 16 , including a vibrating device connected to said hopper.

21. The improvement as defined in claim 16 , wherein said broadcast spreader includes a motor guard that at least partially encapsulates said motor.

22. The improvement as defined in claim 16 , wherein said upper section includes a fill opening in a top surface of said upper section.

23. The improvement as defined in claim 22 , wherein said fill opening is at least partially closed by a removable cap.

24. The improvement as defined in claim 16 , wherein said hopper is a plastic molded unit.

25. The improvement as defined in claim 16 , wherein said bottom and upper sections include multiple wall layers.

26. The improvement as defined in claim 16 , including a screw mechanism adapted to draw particulate material through said lower discharge opening.

27. The improvement as defined in claim 16 , wherein said upper section includes a viewing opening.

28. The improvement as defined in claim 16 , including at least one hook attached to said retaining band and adapted to connect to a tailgate strike pin of said vehicle.

29. The improvement as defined in claim 16 , including a post extending downwardly from said bottom section.

30. The improvement as defined in claim 29 , wherein said post is at least partially adapted to at least partially extend into a hitch ball hole.

31. An improved spreader for mounting on a vehicle and spreading particulate material comprising a hopper having an upper section and a bottom section, said bottom section having a lower material discharge chamber terminating in a lower discharge opening; a broadcast spreader positioned beneath said discharge opening; a motor to rotate at least a portion of said broadcast spreader; a retaining band that at least partially fits about a front face of said upper section; and a band tensioner adapted to at least partially retain said retaining band.

32. The improvement as defined in claim 31 , wherein said front face of said upper section includes an arcuate surface.

33. The improvement as defined in claim 31 , wherein said bottom and upper sections include multiple wall layers.

34. The improvement as defined in claim 31 , wherein said bottom section includes a gripping surface adapted to at least partially maintain at least a portion of said bottom section on a top surface of a bumper of a vehicle.

35. The improvement as defined in claim 31 , including a post extending downwardly from said bottom section.

36. The improvement as defined in claim 35 , wherein said post is at least partially adapted to at least partially extend into an opening in a bumper of a vehicle.

37. The improvement as defined in claim 36 , wherein said opening in said bumper is a hitch ball hole.

38. An improved spreader for mounting on a vehicle and spreading particulate material comprising a hopper having an upper section and a bottom section, said bottom section having a lower material discharge chamber terminating in a lower discharge opening; a broadcast spreader positioned beneath said discharge opening; a retaining band that at least partially fits about a front face of said upper section; and a hook attached to said retaining band, said hook adapted to receive a striker pin to which a tailgate of the vehicle selectively secures.

39. The improvement as defined in claim 38 , including a band tensioner adapted to at least partially tighten said retaining band.

40. The improvement as defined in claim 38 , including a post extending downwardly from said bottom section.
