Row planter
First Claim
1. In a row planter having a furrow opening means mounted for rotation about a horizontal axis perpendicular to the travel direction of the row planter and further having a furrow forming shoe means following said opening means, the improvement comprising:
- means for mounting said opening means and said shoe means with peripheral portions thereof overlapping when viewed from a direction substantially parallel to said horizontal axis of rotation of said opening means and whereinsaid opening means has a first profile when viewed from a point ahead of said row planter in a direction substantially parallel to said direction of travel of said row planter and said overlapping peripheral portion of said shoe means has a second profile, said second profile, when viewed from ahead of said row planter in a direction substantially parallel to said direction of travel of said row planter being smaller than said first profile, and said mounting means including means for mounting said shoe means wherein said second profile lies within said first profile when viewed from said point ahead of said row planter and wherein the remainder of said shoe means has at least a portion thereof with a third profile when viewed from said point ahead of said row planter in a direction substantially parallel to said direction of travel of said row planter with said third profile extending outwardly of said first profile and forming the final shape of the furrow.

Abstract
A row planter having an improved opening means preferably used in combination with a furrow forming shoe. The opening means includes an unitary, disc means mounted for rotation about a horizontal axis and the shoe is mounted so that a peripheral portion thereof overlaps and substantially abuts a peripheral portion of the disc means. The overlapping peripheral portion of the shoe serves to clean the peripheral portion of the disc means and will continue to do so even as the disc means wears down and its diameter begins to diminish. In the preferred embodiment, the overlapping peripheral portion of the shoe is proportioned and mounted so that its profile when viewed from ahead of the row planter falls within the profile of the disc means. In this manner, there is a smooth transition between the furrow opening disc means and the furrow forming shoe. Outwardly of the disc means are positioned depth gauge wheels which are eccentrically mounted relative to the horizontal axis of the disc means. The disc means and depth gauge wheels are mounted on a common support means. To adjust the depth of the row planter, the depth gauge wheels are pivoted in unison along arcuate paths about the horizontal axis of the disc means using a control mechanism positioned outwardly of the depth gauge wheels for easy and quick access.

9. A furrow opening means primarily intended for use in combination with a row planter having a frame, said furrow opening means comprising:
-
disc-shaped means having first and second sides and an axis of symmetry, first and second depth gauge wheels, means for supporting said first and second depth gauge wheels respectively adjacent said first and second sides of said disc-shaped means, said supporting means further including means for respectively mounting said first and second depth gauge wheels for rotation about respective first and second axes and means for mounting said disc-shaped means for rotation about a third axis colinear with said axis of symmetry, said first and second axes being different from said third axis, and, means for mounting said supporting means to the frame of said row planter, said mounting means further including means for repositioning said first and second means for mounting respectively said first and second depth gauge wheels along arcuate paths about said third axis at least between first and second positions with the center of each of said arcuate paths being substantially coincident with said third axis. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A furrow opening means primarily intended for use in combination with a row planter having a frame, said furrow opening means comprising:
-
disc-shaped means having first and second sides and an axis of symmetry, first and second depth gauge wheels, means for supporting said first and second depth gauge wheels respectively adjacent said first and second sides of said disc-shaped means, said supporting means further including means for respectively mounting said first and second depth gauge wheels for rotation about respective first and second axes and means for mounting said disc-shaped means for rotation about a third axis colinear with said axis of symmetry, said first and second axes being different from said third axis and said means for respectively mounting said first and second depth gauge wheels being fixed on an arc having its center on said axis of symmetry, and, means for mounting said supporting means to the frame of said row planter including means for selectively positioning said depth gauge wheels in at least first and second positions relative to said disc-shaped means wherein said respective depth gauge wheels have a side extending outwardly of said respective first and second axes, a generally cylindrical-shaped, ground contacting portion, and means for mounting said ground contacting portion to said respective side members symmetrically about the respective first and second axes with one end of each respective cylindrical-shaped, ground contacting portion being free standing, said furrow forming means further including means for supporting said first and second depth gauge wheels respectively adjacent said first and second sides of said disc-shaped means with said respective free standing ends abutting the respective sides of said disc-shaped means along the entire perimeters of said free standing ends wherein no dirt or other matter can enter the interior of said depth gauge wheels between said free standing ends of said depth gauge wheels and said respective sides of said disc-shaped means. - View Dependent Claims (19, 20)
