Abstract
Abstract A tillage machine includes a main frame that supports rotary soil working tined members and various additional tools that can be detachably fastened to the main frame in combination with the rotary tined members to landscape in one pass. For primary use, a ripper assembly is detachably fastened at the front of the frame in advance of the rotary soil working members. A pulverizer-support roller is detachably fastened to the frame in a trailing position and a leveler bar supported between the roller and the rotary members to prevent ridging. A seed box with delivery system can be mounted on the roller frame and driven by a transmission connected to the roller axle. A packer roller is detachably pivoted to the frame to leave the ground in a finished condition.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
161 words
A tillage implement comprising a frame and a portion of said frame being supported by frame beams that extend in a direction transverse to the direction of travel, a plurality of soil working members being mounted on upwardly extending shafts that are connected to driving means supported by said frame portion, a ground engaging roller being located to the rear of said soil working members and said roller being pivotally interconnected to said frame by side arms with means that adjusts the relative position of said roller to said frame, a further beam supported between said arms and a downwardly depending leveler member being connected to the further beam, said leveler member being normally positioned forwardly of said roller and adjacent the rear of said soil working members to receive soil displaced by the soil working members in advance of the roller, pivot means detachably connecting said arms, together with said leveller member and roller, to the remainder of said implement.
Claim 2
Dependent Claim
161 words
A tillage implement comprising a frame and a portion of said frame being supported by frame beams that extend in a direction transverse to the direction of travel, a plurality of soil working members being mounted on upwardly extending shafts that are connected to driving means supported by said frame portion, a ground engaging roller being located to the rear of said soil working members and said roller being pivotally interconnected to said frame by side arms with means that adjusts the relative position of said roller to said frame, a further beam supported between said arms and a downwardly depending leveler member being connected to the further beam, said leveler member being normally positioned forwardly of said roller and adjacent the rear of said soil working members to receive soil displaced by the soil working members in advance of the roller, pivot means detachably connecting said arms, together with said leveller member and roller, to the remainder of said implement.
Claim 3
Dependent Claim
18 words
The implement of claim 1, wherein said further beam is elongated and extends parallel to said frame beams.
Claim 4
Dependent Claim
32 words
The implement of claim 2, wherein said frame beams include a forward and a rear beam that are interconnected with side beams and said further beam is located below said rear beam.
Claim 5
Dependent Claim
51 words
The implement of claim 3, wherein a ripper assembly is detachably connected to said forward beams by fastening means and said assembly includes a foremost beam with ripper teeth depending from the forward frame beam, arm supports at the lateral sides of said foremost beam interconnecting said assembly to said frame.
Claim 6
Dependent Claim
36 words
The implement of claim 3, wherein a seed box is positioned above said roller and connected to said further beam by supports, said box having an opening that is located adjacent the rear of the roller.
Claim 7
Dependent Claim
59 words
The implement of claim 3, wherein said frame portion is interconnected to said frame beams by a parallelogram linkage comprised by two links that are angled to extend forwardly in the general direction of travel, the front ends of said links being located higher than the trailing ends thereof and said front ends being pivoted to said forward beam.
Claim 8
Dependent Claim
48 words
The implement of claim 1, wherein said leveler member is an elongated bar that has a flat side inclined between the horizontal and vertical, said leveler member having a lower trailing edge that is positionable at substantially the same level as the ground engaging surface of said roller.
Claim 9
Dependent Claim
40 words
The implement of claim 1, wherein a packer roller with mounting arms is positioned to trail said first mentioned roller and bear on the ground, said mounting arms being detachably connected to the side arms of the first mentioned roller.
