Abstract

The gravel spreader includes a hopper with a pair of longitudinally opposed sidewalls, a pair of laterally opposed sidewalls, an open upper end and an open lower end. A pair of longitudinally-extending runners are respectively mounted on lower ends of the pair of laterally opposed sidewalls. In use, the gravel spreader is transported to a site for spreading of gravel by being releasably carried by a bucket of a tractor or the like. The gravel spreader is placed on a ground surface of the site for the spreading of the gravel and the bucket of the tractor is disengaged from the gravel spreader. The hopper is at least partially filled with the gravel to be spread and the gravel spreader is pulled over the ground surface using the bucket of the tractor, with the pair of longitudinally-extending runners sliding on the ground surface.

Claims (35)

1 . A gravel spreader, comprising:

a hopper having a pair of longitudinally opposed sidewalls, a pair of laterally opposed sidewalls, an open upper end and an open lower end;

a pair of longitudinally-extending runners respectively mounted on lower ends of the pair of laterally opposed sidewalls;

a crossbar mounted on, and extending between, respective first ends of the pair of longitudinally-extending runners;

a plurality of angled ribs mounted on inner faces of the pair of longitudinally opposed sidewalls of the hopper; and

a cover for releasably covering the open upper end of the hopper, wherein the cover has a plurality of slots formed therethrough.

2 . The gravel spreader as recited in claim 1 , further comprising a platform mounted on, and extending between, respective second ends of the pair of longitudinally-extending runners.

3 . The gravel spreader as recited in claim 1 , wherein the first ends and second ends of each of the longitudinally-extending runners are pivotable with respect to a central portion of the respective one of the longitudinally-extending runners.

4 . The gravel spreader as recited in claim 1 , further comprising a reinforcing bar secured to an upper surface of the crossbar.

5 . The gravel spreader as recited in claim 1 , wherein the hopper is pivotable with respect to the pair of longitudinally-extending runners.

6 . The gravel spreader as recited in claim 1 , wherein the cover is pivotally secured to an upper edge of one of the longitudinally opposed sidewalls.

7 . The gravel spreader as recited in claim 1 , wherein a lip is mounted on the hopper adjacent the open lower end thereof.

8 . The gravel spreader as recited in claim 1 , wherein the slots of the cover are defined by a plurality of angled slats.

9 . A gravel spreader, comprising:

a hopper having a pair of longitudinally opposed sidewalls, a pair of laterally opposed sidewalls, an open upper end and an open lower end;

a pair of longitudinally-extending runners respectively mounted on lower ends of the pair of laterally opposed sidewalls;

a plurality of angled ribs mounted on inner faces of the pair of longitudinally opposed sidewalls of the hopper; and

a cover for releasably covering the open upper end of the hopper, wherein the cover has a plurality of slots formed therethrough.

10 . The gravel spreader as recited in claim 9 , further comprising a crossbar mounted on, and extending between, respective first ends of the pair of longitudinally-extending runners.

11 . The gravel spreader as recited in claim 10 , further comprising a reinforcing bar secured to an upper surface of the crossbar.

12 . The gravel spreader as recited in claim 9 , further comprising a platform mounted on, and extending between, respective second ends of the pair of longitudinally-extending runners.

13 . The gravel spreader as recited in claim 9 , wherein first and second ends of each of the longitudinally-extending runners are pivotable with respect to a central portion of the respective one of the longitudinally-extending runners.

14 . The gravel spreader as recited in claim 9 , wherein the cover is pivotally secured to an upper edge of one of the longitudinally opposed sidewalls.

15 . The gravel spreader as recited in claim 9 , wherein the slots of the cover are defined by a plurality of angled slats.

16 . The gravel spreader as recited in claim 9 , wherein the hopper is pivotable with respect to the pair of longitudinally-extending runners.

17 . The gravel spreader as recited in claim 9 , wherein a lip is mounted on the hopper adjacent the open lower end thereof.

18 . A method of spreading gravel, comprising:

transporting a gravel spreader to a site for spreading of gravel, wherein the gravel spreader comprises a hopper having a pair of longitudinally opposed sidewalls, a pair of laterally opposed sidewalls, an open upper end and an open lower end, and wherein the gravel spreader further comprises a pair of longitudinally-extending runners respectively mounted on lower ends of the pair of laterally opposed sidewalls, the gravel spreader being releasably carried by a bucket of a tractor;

placing the gravel spreader on a ground surface of the site for the spreading of the gravel;

disengaging the bucket of the tractor from the gravel spreader;

at least partially filling the hopper with the gravel to be spread; and

pulling the gravel spreader over the ground surface using the bucket of the tractor, the pair of longitudinally-extending runners sliding on the ground surface.

19 . The method of spreading gravel as recited in claim 18 , wherein a crossbar is mounted on, and extends between, respective ends of the pair of longitudinally-extending runners, the gravel spreader being releasably carried by the bucket of the tractor with the bucket releasably contacting the crossbar and the open lower end of the hopper.

20 . The method of spreading gravel as recited in claim 18 , wherein a plurality of angled ribs are mounted on inner faces of the pair of longitudinally opposed sidewalls of the hopper, the ribs directing the gravel during the filling of the hopper therewith toward the pair of laterally opposed sidewalls of the hopper.

21 . The method of spreading gravel as recited in claim 18 , wherein a cover releasably covers the open upper end of the hopper, wherein the cover has a plurality of slots formed therethrough, and wherein the slots of the cover are defined by a plurality of angled slats, the gravel being evenly distributed within the hopper during the filling thereof with the gravel by passage through the slots over the plurality of angled slats.
