Abstract

A seed planting assembly comprises a depth regulating member and a residue driving member. The depth regulating member and residue driving member may be integrally formed as one structure, or they may be formed separately and later joined to one another. A method of planting comprises selecting the geometries of the depth regulating member and residue driving member for a given set of conditions so that the depth regulating member facilitates travel of a planting unit over debris.

Claims

1. A seed planting assembly comprising:

a. a laterally extending support member;

b. a planting unit including a planting frame supported by said support member, wherein said planting unit frame carries;

i. a furrow opening assembly operable to create a furrow in a ground surface;

ii. a seed delivery assembly for delivery of seeds into said furrow;

iii. a furrow closing assembly operable to close said furrow;

iv. a depth regulating member having a vertical position relative to said furrow opening assembly, wherein said depth regulating member responds to forces upon said planting unit to control ground surface engagement;

v. an arm assembly connecting said depth regulating member to said planting unit frame;

vi. a stop member mechanically engaging a portion of said arm assembly for defining a limit for vertical motion of said depth regulating member in the direction substantially opposite said ground surface; and

,

vii. a residue driving member cooperatively engaged with said depth regulating member wherein said residue driving member drives residue opposite the direction of travel of said seed planting assembly.

2. The seed planting assembly as set forth in claim 1 wherein said depth regulating member is further defined as a gauge wheel.

3. The seed planting assembly as set forth in claim 2 wherein said residue driving member is affixed to said depth regulating means via an affixing member.

4. The seed planting assembly as set forth in claim 3 wherein said residue driving member is further defined as a tire having a diameter from 5 percent to 40 percent less than the diameter of said gauge wheel and wherein said tire has a width from 100 percent to 300 percent greater than the width of said gauge wheel.

5. The seed planting assembly as set forth in claim 3 wherein said residue driving member is further defined as an adjustable diameter wheel.

6. The seed planting assembly as set forth in claim 2 wherein said gauge wheel incorporates both a first and second diameter, wherein said gauge wheel functions both as a depth regulating member and a residue driving member.

7. The seed planting assembly as set forth in claim 6 wherein said gauge wheel incorporates a plurality of diameters to regulate the depth of said furrow opening assembly and functions as both a depth regulating member and a residue driving member.

8. The seed planting assembly as set forth in claim 1 wherein a row cleaning member is positioned anterior with respect to said seed planting assembly.

9. The seed planting assembly as set forth in claim 7 wherein a row cleaning member is positioned anterior with respect to said planting unit and said gauge wheel.

10. The seed planting assembly as set forth in claim 1 wherein said residue driving member and said depth regulating member are cooperatively arranged in pairs on adjacent planting units and wherein the total width of said pairs is less than the row width spacing defined by said adjacent pairs of planting units.

11. A method of plating comprising the steps of:

a. determining an optimum distance between adjacent rows for a specific material to be planted;

b. engaging a prime mover with a planting unit comprising;

i. a furrow opening assembly operable to create a furrow in a ground surface;

ii. a seed delivery assembly for delivery of seeds into said furrow;

iii. a furrow closing assembly operable to close said furrow;

iv. a depth regulating member having a vertical position relative to said furrow opening assembly, wherein said depth regulating member responds to forces upon said planting unit to control ground surface engagement;

v. an arm assembly connecting said depth regulating member to said planting unit frame;

vi. a stop member mechanically engaging a portion of said arm assembly for defining a limit for vertical motion of said depth regulating member in the direction substantially opposite said ground surface;

vii. a residue driving member cooperatively engaged with said depth regulating member wherein said residue driving member drives residue opposite the direction of travel of said seed planting assembly;

c. selecting the diameter and width of said depth regulating member and said residue driving member with respect to said optimum distance between rows such that said residue driving member facilitates travel of said planting unit over debris.
