## Abstract

A cutter apparatus comprising a frame having a mounting member connectable to a piece of prime mover equipment; a cutter assembly connected to the frame, the cutter assembly comprising a support member having a first end; a drive shaft having a first end journaled to the first end of the support member; and a plurality of discrete cutter members stacked on the drive shaft so as to be engaged with an adjacent one of the cutter members, each of the cutter members having at least one cutting edge; and a drive assembly connected to the drive shaft in a way that activation of the drive assembly causes the drive shaft to rotate and thereby rotate the cutter members. The frame may have a base and an extension arm pivotally connected to the base. The support member may be pivotally connected to the extension arm.

## Claims

### Claim 1

A cutter assembly, comprising:
a drive shaft having a first end and a second end; and
a plurality of discrete cutter members stacked on the drive shaft so as to be engaged with an adjacent one of the cutter members, each of the cutter members having at least one cutting edge,
wherein the cutter members are stacked on the drive shaft in a way that the cutting edges are arranged in a helical pattern, and
wherein a bottom side of each of the cutter members has a notch for matingly receiving a top side of the adjacent cutter member.

### Claim 2

A cutter assembly, comprising:
a support member having a first end and a second end;
a drive shaft having a first end and a second end, the first end of the drive shaft journaled to the first end of the support member;
a plurality of discrete cutter members stacked on the drive shaft so as to be engaged with an adjacent one of the cutter members, each of the cutter members having at least one cutting edge, wherein the cutter members are stacked on the drive shaft in a way that the cutting edges are arranged in a helical pattern, and wherein a bottom side of each of the cutter members has a notch for matingly receiving a top side of the adjacent cutter member; and
a drive assembly connected to the drive shaft in a way that activation of the drive assembly causes the drive shaft to rotate and thereby rotate the cutter members.

### Claim 3 (depends on 2)

The cutter assembly of claim 2, wherein the cutter members are slideable along on the drive shaft when the first end of the support member is disconnected from the first end of the drive shaft.

### Claim 4

A cutter assembly, comprising:
a drive shaft having a first end and a second end; and
a plurality of discrete cutter members stacked on the drive shaft so as to be engaged with an adjacent one of the cutter members, each of the cutter members having a body with a top side, a bottom side, a through-hole extending from the top side to the bottom side and slidably receivable of the drive shaft, a first cutting edge, and a second cutting edge arranged in a diametrically opposed relationship with respect to the first cutting edge, the first cutting edge and the second cutting edge extending from the top side to the bottom side in a parallel relationship to one another,
wherein the cutter members are stacked on the drive shaft in a way that the first cutting edges and the second cutting edges are arranged in a helical pattern, and
wherein the bottom side of the body of each of the cutter members has a notch for matingly receiving the top side of the adjacent cutter member.
