Abstract

A trash farming implement is provided with a plurality of tillage assemblies on an implement, each tillage assembly having a tillage disc arranged to rotate about an axis which is inclined slightly from the vertical both in end elevation and in side elevation so that it slopes upwardly and forwardly in the direction of travel, and also a soil replacing disc which has an axis of rotation which is nearly horizontal but slopes upwardly towards the tillage disc to which it is adjacent, the disc being so located that a furrow cut by the tillage disc will be filled by replacement of the lifted soil to its original position.

Claims

1. A trash farming implement adapted to travel in a given direction, comprising:

frame means;

generally horizontally disposed rotatable tillage means supported on said frame means inclined with respect to the ground so that as said tillage means is moved along the ground, the lowermost peripheral portion thereof is in contact with the ground, said lowermost portion being disposed forwardly and to one lateral side of the central region of the tillage means, with respect to said given direction of travel, whereby said tillage means, in operation, displaces soil in a first direction rearwardly and laterally toward said one side of said tillage means;

generally vertically disposed soil replacement plate means;

means mounting said soil replacement plate means on said frame means for movement along the ground, said soil replacement plate means being positioned such that the lowermost portion of the periphery thereof is adapted to contact the soil displaced by said tillage means adjacent the periphery of said tillage means at a location on said one side rearwardly of said lowermost peripheral portion of the latter, whereby soil displaced by said tillage means is displaced in said first direction toward said soil replacement means and is redirected by the latter in a direction so as to generally replace the soil in substantially its original position.

2. A trash farming implement according to claim 1 wherein said tillage means comprises a disc whose axis of rotation is inclined to the vertical in end elevation by an angle of between 8°

and 28°

.

3. A trash farming implement according to claim 1 wherein said tillage means comprises a disc whose axis of rotation is inclined to the vertical in side elevation by an angle of between 5°

and 25°

.

4. A trash farming implement according to claim 1 wherein each said tillage frame comprises a mounting bracket arranged to be mounted to said main frame and an arm pivoted to the mounting bracket, the arm trailing the mounting bracket and carrying said tillage disc on its lower end, and a stump jump spring between said arm and mounting bracket.

5. A trash farming implement according to claim 1 wherein said tillage means comprises bearings and said bearings surround a hollow tube.

6. A trash farming implement according to claim 5 further comprising a dust cover surrounding said hollow tube.

7. A trash farming implement according to claim 5 further comprising deflector means on the lower end of said hollow tube arranged to deflect seed towards the lowermost point of the periphery of the tillage disc.

8. A trash farming implement according to claim 5 further comprising a seed feed hose secured to the upper end of said hollow tube.

9. A trash farming implement according to claim 5 wherein said soil replacement means comprises a soil replacing disc having a convex side and a concave side, and further comprising a plurality of lugs circumferentially spaced around said convex side.

10. A trash farming implement according to claim 1, wherein said soil replacement plate means comprises a rotatable soil replacement disc.

11. A trash farming implement according to claim 1, wherein said soil replacement plate means has a concave surface for contacting the soil displaced by said tillage means.

12. A trash farming implement adapted to travel in a given direction, comprising:

a frame;

a generally horizontally disposed tillage disc;

means supporting said tillage disc on said frame for rotation about an axis which is inclined to the vertical in end elevation, and which is also inclined to the vertical in side elevation so as to slope generally upwardly and forwardly in the direction of travel,

a generally vertically disposed soil-replacement disc,

means supporting said soil replacement disc on said frame, for rotation about an axis which is inclined to the horizontal in end elevation and which is also inclined with respect to the direction of travel so as to slope generally upwardly and forwardly in a direction toward the axis of said tillage disc, said tillage disc and said soil-replacement disc being positioned relative to each other such that the respective lowermost peripheral regions of each are generally adjacent to each other, whereby soil displaced by the tillage disc in one transverse direction is redirected by the soil-replacement disc in the opposite transverse direction.

13. A trash farming implement having a main frame and a plurality of tillage assemblies thereon,

at least one tillage disc on each said tillage frame, bearings operatively disposed between each tillage disc and its tillage frame supporting that disc for rotation about an axis which is inclined to the vertical in end elevation, and which is also inclined to the vertical in side elevation so as to slope upwardly and forwardly in the direction of travel, and

soil replacement means also on that said tillage frame, and so located and oriented that soil displaced by the tillage disc in one transverse direction is redirected by the soil replacement means in the opposite direction, each said soil replacement means comprising a soil replacing disc on a respective said tillage frame, further bearings operatively disposed between the said replacing disc and its tillage frame supporting that disc for rotation about an axis which is inclined to the horizontal in end elevation to slope transversely upwardly in a direction towards said tillage disc on that frame, and which is inclined to the direction of implement travel in plan to define an obtuse angle therewith such that the replacing disc is rearward of the tillage disc,

the lowermost points on the peripheries of the discs on each said tillage frame being adjacent each other.

14. A trash farming implement according to claim 13 wherein said inclination of axis of rotation of each said replacing disc slopes transversely at an angle of between 12°

and 32°

.

15. A trash farming implement according to claim 13 wherein said obtuse angle is between 91°

and 135°

.

16. A trash farming implement according to claim 13 wherein the lowermost point of the tillage disc periphery is below the lowermost point of the soil replacing disc.

17. A trash farming implement according to claim 13 comprising at least four rows of tillage frames carried by said main frame, each said tillage frame having one said tillage disc and one said soil replacing disc, said discs being so spaced from one another transversely as to form a plurality of equally spaced rows of cultivation.

18. A method of tilling soil comprising moving a plurality of tillage discs of a trash farming implement according to claim 13 over an area of soil, lifting the soil with the tillage discs so as to form furrows beneath respective discs and replacing said soil into said furrows by moving it transversely by said soil replacing discs.

19. A method of tilling and seeding an area of soil with a machine according to claim 13 wherein said tillage disc bearings surround a hollow tube on each respective said tillage frame, and comprising passing seed and fertilizer through said hollow tube, deflecting the seed and fertilizer beneath the tillage disc towards the lowermost point of its periphery, and replacing the soil distributed by the tillage disc by moving it transversely with a said soil replacing disc on that tillage frame.
