### Claim 16

A two stage snow thrower comprising:
a one piece deep drawn auger housing having a mouth;
an augur supported from opposite sides of the housing;
an impeller can extending from the housing;
an impeller within the can; and
a chute extending from the impeller can.

### Claim 17 (depends on 16)

The snow thrower of claim 16, wherein the auger housing omits welds and is formed from a single deformed sheet of material.

### Claim 18 (depends on 16)

The snow thrower of claim 16, wherein the mouth is flared out.

### Claim 19 (depends on 16)

The snow thrower of claim 16, wherein the impeller is supported for rotation about an axis, wherein the housing includes a first flange having a first face extending non-parallel to the axis and wherein the impeller can includes the second flange having a second face extending non-parallel to the axis in abutment with the first face.

### Claim 20 (depends on 19)

The snow thrower of claim 19, wherein the first face and the second face are each coated with a layer of paint.

### Claim 21 (depends on 19)

The snow thrower of claim 19 further comprising at least one fastener extending through the first flange and the second flange.

### Claim 22 (depends on 19)

The snow thrower of claim 19, wherein one of the first flange and the second flange has a depression receiving the other of the first flange and the second flange.

### Claim 23 (depends on 16)

The snow thrower of claim 16 further comprising a bent C-shaped bar coupled to the auger housing so as to serve as a scraper and to strengthens the mouth of the housing.

### Claim 24

A method comprising:
providing a single sheet of material;
deep drawing the single sheet of material in at least one die to form a one piece auger housing having a bottom portion, a top portion, a central portion between the bottom portion and the top portion, a first side portion and a second side portion opposite the first side portion.

### Claim 25 (depends on 24)

The method of claim 24, wherein the auger housing includes a first annular flange having a first face and wherein the method further comprises securing a second face of a second flange of an impeller in abutment with the first face, wherein the first face and the second phase extend non-parallel to a centerline of the impeller can.

### Claim 26 (depends on 25)

The method of claim 25 further comprising coating the first face and the second face with paint prior to securing the first face and the second face in abutment with one another.

### Claim 27 (depends on 25)

The method of claim 25, wherein securing the first face in abutment with the second phase comprises fastening the first flange to the second flange.

### Claim 28 (depends on 27)

The method of claim 27, wherein fastening the first flange to the second flange comprises inserting one or more fasteners through the first flange and the second flange.

### Claim 29 (depends on 25)

The method of claim 25 further comprising positioning one of the first flange and the second flange in a recess in the other of the first flange and the second flange.

### Claim 30 (depends on 24)

The method of claim 24, wherein during deep drawing of the auger housing, a mouth of the auger housing is flared outwardly to increase a snow cutting area of the mouth of the auger housing.

### Claim 31 (depends on 24)

The method of claim 24 further comprising rotatably supporting an augur within the auger housing.

### Claim 32

(canceled)
