Abstract

An improved depth regulating member comprising: a first portion, the first portion positioned adjacent a furrow forming assembly for engagement with ground surface adjacent a furrow; and a second portion, the second portion positioned adjacent the first portion opposite the surface of the first portion adjacent the furrow forming assembly, wherein the second portion engages and drives residue through the area between adjacent furrow forming assemblies opposite the direction of travel of the furrow forming assembly.

Claims

1. A multi diameter gauge wheel comprising:

a. a first portion, wherein said first portion is positioned adjacent a furrow forming assembly, and wherein said first portion limits the depth to which said furrow forming assembly penetrates the ground surface during the formation of a furrow; and

b. a second portion, wherein said second portion is positioned adjacent said first portion, wherein the diameters of said first and second portions are selected so that the diameter of said second portion is between 10 and 40 percent less than the diameter of said first portion.

2. The gauge wheel as set forth in claim 1 wherein said first portion and said second portion are integral and continuous.

3. The gauge wheel as set forth in claim 1 wherein the width of said first portion is less than the width of said second portion.

4. The gauge wheel as set forth in claim 1 wherein said first portion is not filled with a compressed fluid.

5. The gauge wheel as set forth in claim 1 wherein said second portion is not filled with a compressed fluid.

6. The gauge wheel as set forth in claim 1 wherein said second portion is filled with a compressed fluid.

7. The gauge wheel as set forth in claim 1 wherein said first portion is filled with a compressed fluid.

8. The multi diameter gauge wheel according to claim 1 wherein said first and second portion are further defined as being separately formed from one another.
