Abstract

A pair of laterally and vertically spaced powered auger type plow arrangements in furrow overlapping relation to one another and coupled to the rear of a tractor, each plow arrangement including a tubular auger housing and auger disposed therein and inclined downward at its forward end, the auger having a protruding earth penetrating tapered nose portion and a removable leading cutting edge with forward scarifiers thereon spaced just rearwardly of the nose portion and an auger shaft extending longitudinally in the housing and having a plurality of rearwardly located screw lead portions, the housing having a forward downwardly rearwardly sloped flat portion and an elliptical inlet opening therein and having laterally rearwardly curved rear end portion having adjustable discharge opening whereby the earth is scooped into the front of each arrangement and discharged out the rear and upwardly therefrom propelling the plow arrangements forwardly in aid of the motive power of the tractor.

Claims

1. A plow arrangement for tillage of the soil comprising:

plow supporting structure, plow means including a plow unit carried by the supporting structure, said plow unit including a longitudinally extending generally cylindrically shaped housing having a front end soil entrance means at the front of the plow unit and a rear end soil discharge means at the rear of the plow unit longitudinally spaced from the front end soil entrance means, said supporting structure fixedly supporting said housing against rotation and at an inclination to the ground of the soil to be cut with the forward end of the housing being tilted downward with the rearward end of the plow being tilted upward, drive means adapted to be connected to a tractor, said plow unit including a rotatable auger disposed within the housing means and connected to be rotatably driven by said drive means and extending lengthwise of the housing means between the entrance means and the discharge means, the auger and housing having substantially a common longitudinal axis, the auger having a forward initial earth penetrating and cutting edge portion extending forwardly outwardly of the front entrance means and being substantially centrally disposed of the housing, and said auger having a rearwardly extending auger screw portion attached to the rear of the cutting portion and adjacent with the interior of the housing for directing the soil cut by the cutting edge portion rearwardly longitudinally of the plow and out the rear discharge means at the rear end of the plow, the forward portion of the front end soil entrance means has its upper portion extending in shielding manner over the Forward portion of the auger screw portion and the cutting portion to prevent the sheared off soil from being cast off the auger, the lower portion of the front end soil entrance means being spaced rearwardly relative to the forward portion of the auger cutting portion with a portion of the auger cutting portion protruding from the housing for penetrating the soil ahead of the housing, whereby the forwardly and downwardly inclined housing and auger positions the forward auger cutting edge portions to shave off the earth and it is carried into the housing where the rotating action of the auger in the housing crumbles and aerates the earth and deposits same through the rear discharge means providing a furrow cut in the soil in which the trailing housing can travel.

2. The invention according to claim 1, and said plow supporting structure including a main frame fixedly supporting said plow means and tractor linkage pivotally connecting with said main frame.

3. The invention according to claim 1, and said plow means including a second plow unit, each plow unit extending longitudinally in the direction of tillage travel and one of said plow units being spaced in lateral and rearward furrow overlapping relation with respect to the other plow unit.

4. The invention according to claim 1, and said front entrance means having a front face portion inclined downwardly and rearwardly and each auger having a forward nose tip adapted to engage the soil due to the inclination of the plow unit and due to the inclination of the front face portion of the plow unit.

5. The invention according to claim 1, and said front end soil entrance means having its front face portion being tapered downwardly and rearwardly and having a front end soil receiving annular opening in said tapered face portion, the lower portion of said cutting portion extending outwardly of the lower portion of said face portion with the upper portion of the cutting portion being shielded by the forward upper portion of the entrance means.

6. The invention according to claim 1, and said cutting edge portion being removably attached to said auger screw portion.

7. The invention according to claim 1, and said cutting portion being provided with scarifying means.

8. The invention according to claim 1, and said rear end soil discharge means including a tapered rear end portion of said housing means and being provided with a side and upper discharge opening for side discharge of the soil from the housing means and upwardly from said housing means.
