Abstract

A method of raking with a tractor having a rear horizontally elongated hydraulic blade. After attachment the rake can be can be lifted, lowered, and pressed down into the soil or gravel etc. being raked with hydraulic power. The method comprises the following steps: providing a horizontally elongate member adapted to be carried adjacent, parallel to, and beneath the bottom portion of the blade, said member having teeth spaced along and extending downwardly therefrom; providing blade attachment devices affixed along the elongate member for releasably attaching the member beneath the bottom portion of the blade; and, releasably attaching the elongate member to the blade on the tractor. In a preferred embodiment of this invention the elongated member comprises a channel, the blade attachment devices comprise arms which extend from opposite side portions of the channel and surround the blade, and the teeth comprise hardened replaceable bolts.

Claims

1. A method of raking with a small tractor having a blade dragged therebehind comprising the following steps:

providing an elongate blade seating member, having a length substantially at least as long as the blade on the tractor, and adapted to be carried directly adjacent, parallel to, and beneath the bottom cutting portion of the blade, said member having teeth spaced along, individually attached thereto, and extending downwardly therefrom;

providing pairs of spaced opposite upright straps, each strap having a lower and an upper portion, and each pair of straps having a front strap having a lower portion attached to a front side portion of the blade seating member, and a rear strap having a lower portion attached to a rear side portion of the blade seating member, so that together the front and rear straps extend upwardly around the blade;

providing a releasable attachment means having two aligned holes each extending through, the upper portion of the opposite straps and a bore aligned with the holes extending through a central portion of the blade;

positioning the upper portions of the front and rear straps around the blade so that the holes and bore are in alignment; and

,

attaching said front and rear straps together by a member extending through the holes and bore, said blade seating member thereby secured by the straps beneath the blade;

so that the spaced teeth can be dragged behind the tractor and pressed downwardly with the hydraulic mechanism on the blade.

2. A method of raking as in claim 1 wherein the blade seating member comprises a channel.

3. A method of raking as in claim 2 wherein the length of the channel substantially exceeds the length of the blade.

4. A method of raking as in claim 3 wherein the rake is secured to the blade by and only by the straps and releasable attachment means.

5. A method of raking as in claim 4 wherein the member extending through the hole comprises a bolt which is held in position by a nut.

6. A method of raking as in claim 5 wherein the straps comprise strips of flexible metal so that they may first spring apart from one another to accept insertion of the blade therebetween, and subsequently may spring together to be tightly bolted with the bolt extending through and between upper portions of the straps and through the bore in the blade.

7. A method of raking as in claim 6 wherein there are two and only two pairs of upright straps, each pair of straps extending upwardly from an opposite end portion of the blade.

8. A method of raking as in claim 7 wherein the channel has a front, center, and rear web portion, each of which extend upwardly;

and further comprising the steps of positioning a bottom cutting portion of the blade directly adjacent to a back side portion of the center web;

providing a front row of laterally spaced teeth extending downwardly from between the front and center webs; and

a rear row of teeth, laterally shifted from the front row of teeth to rake between the teeth in the front row, and extending downwardly from between the center and rear webs.

9. A rake method of raking as in claim 8 wherein the teeth comprise replaceable bolts.

10. A rake attachment for a tractor having a horizontally elongate blade comprising:

an elongate blade seating member having a length at least substantially as long as the blade on the tractor, and adapted to be carried directly adjacent, parallel to, and beneath the bottom cutting portion of the blade;

teeth spaced along, individually rigidly attached to, and extending downwardly beneath the elongate member;

pairs of spaced opposite upright straps, each strap having a lower and an upper portion, and each pair of straps having a front strap having a lower portion attached to a front side portion of the blade seating member, and a rear strap having a lower portion attached to a rear side portion of the blade seating member, so that together the front and rear straps extend upwardly around the blade;

a releasable attachment means having two aligned holes extending through the upper portion of the opposite straps, and a bore aligned with the holes extending through a central portion of the blade, and wherein said front and rear straps are attached together by a member extending through the holes and bore; and

,

a member extending through the holes and bore for releasably attaching the upper portions of front and rear straps together around the blade, said rake attachment thereby secured to and beneath the blade.

11. A rake as in claim 10 wherein the horizontally elongate member comprises a channel.

12. A rake as in claim 11 wherein the length of the channel exceeds the length of the blade.

13. A rake as in claim 12 wherein the rake is secured to the blade by and only by the straps and releasable attachment means.

14. A rake as in claim 13 wherein the member extending through the hole comprises a bolt which is held in position by a nut.

15. A rake as in claim 14 wherein the straps comprise strips of flexible metal so that they may first spring apart from one another to accept insertion of the blade therebetween, and subsequently may spring together to be tightly bolted with the bolt extending through and between upper portions of the straps and, through the bore in the blade.

16. A rake as in claim 15 wherein there are two and only two pairs of upright straps each pair of straps extending upwardly from an opposite end portion of the blade.

17. A rake as in claim 14 wherein the channel has a front row and a rear row of laterally spaced teeth, each of the teeth in the rear row laterally moved to rake in between the teeth in the front row;

and wherein a bottom cutting portion of the blade is positioned directly adjacent to a back side portion of the center web.

18. A rake as in claim 17 wherein the teeth comprise replaceable bolts.
