Abstract
Abstract An earth leveling implement employs a transverse horizontal auger type excavator backed up by a vertically adjustable mold board mounted on the front of a vehicle for controlled vertical positioning and tilting; a ditcher can be attached at one side of the grader, and the vehicle can include a compactor to enable a single operator to perform the earth grading and compacting operations in a single operation.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
225 words
In an earth working implement, the combination including chassis means having transversely disposed helically surfaced auger means mounted at the forward end thereof for initially excavating and transversely distributing surface material, transversely disposed mold board means mounted on the chassis means behind said auger means for controlling the depth and distribution of material excavated by said auger means, a pair of ground engaging traction wheels mounted on said chassis means rearwardly of said auger means, transversely disposed ground engaging roller means mounted at rearward portion of said chassis means substantially in alignment with and substantially equal in width as said mold board means for compacting material distributed by said mold board means, prime mover means mounted on said chassis means and means connecting the prime mover means with said traction wheels and said auger means for driving said traction wheels for movement in forward and reverse directions and for rotating said auger means and means on said chassis means for steering said implement, said chassis means also including means connected with the auger means for raising and lowering and tilting said auger means and mold board means with respect to the ground, said mold board means having a transverse lower edge and including means connected between the auger meAns and mold board means for raising and lowering said lower edge independently of said auger means.

Claim 5
Dependent Claim
50 words
The invention defined in claim 1, wherein said implement also includes auxiliary surface grading means extending transversely outwardly beyond one of the ends of said auger means and pivotally mounted on said chassis means to be positioned in angular relationship to said auger means with respect to a vertical plane.
Claim 6
Dependent Claim
32 words
The invention defined in claim 4, wherein said auxiliary surface grading means comprises an auxiliary transversely dipsosed auger means, and vertically adjustable auxiliary mold board means mounted behind said auxiliary auger means.
Claim 7
Dependent Claim
34 words
The invention defined in claim 1, wherein said auger means includes reversible hydraulic motor means for rotating said auger means and said prime mover means includes hydraulic pump means for driving said motor means.
Claim 8
Dependent Claim
27 words
The invention defined in claim 6, wherein said chassis means includes hydraulic actuator means for said raising and lowering of said auger means and mold board means.
Claim 9
Dependent Claim
