Agricultural apparatus with hybrid single-disk, double-disk coulter arrangement
First Claim
1. An agricultural furrow opening system comprising:
- a towing frame for being coupled to a tractor, the towing frame being configured to move in the direction of travel along a surface of a field;
an attachment frame adapted to be rigidly connected to the towing frame; and
a swing-arm having a distal end and a proximal end, the proximal end coupled to the attachment frame;
a primary disk coupled to the distal end of the swing-arm and configured to rotate about a first axis, the primary disk being rolled about the direction of travel at a first oblique angle θ
P and yawed about a vertical direction at a second oblique angle ζ
P, the vertical direction being generally perpendicular to the direction of travel and extending upwards from the surface of the field; and
a deflecting disk coupled to the distal end of the swing-arm and configured to rotate about a second axis, the deflecting disk being rolled about the direction of travel at a third oblique angle θ
D and yawed about the vertical direction at a fourth oblique angle ζ
D, the first oblique angle θ
P being disposed between the vertical direction and the third oblique angle θ

Abstract
An agricultural furrow opening system having a hybrid single-disk, double-disk opener is disclosed including a swing-arm, a primary disk, and a deflecting disk. The primary disk is coupled to a distal end of the swing-arm and configured to rotate about a first axis. The primary disk is rolled about a direction of travel at a first oblique angle θP and yawed about a vertical direction at a second oblique angle ζP. The deflecting disk is coupled to the distal end of the swing-arm and configured to rotate about a second axis. The deflecting disk is rolled about the direction of travel at a third oblique angle θD and yawed about the vertical direction at a fourth oblique angle ζD. The first oblique angle θP is between the vertical direction and the third oblique angle θD.

8. An agricultural furrow opening system comprising:
-
a towing frame; a swing-arm having a distal end and a proximal end, the proximal end being coupled to the towing frame; a housing coupled to the distal end of the swing-arm, the housing including an outer surface having a seat configured to receive at least one outer bearing, the at least one outer bearing defining a first axis of rotation, and an inner bore configured to receive a spindle, the spindle disposed within a perimeter of the seat, the spindle defining a second axis of rotation different than the first axis of rotation; a primary disk coupled to the distal end of the swing-arm and configured to rotate about the first axis of rotation; and a deflecting disk coupled to the distal end of the swing-arm and configured to rotate about the second axis of rotation. - View Dependent Claims (9, 10, 11)
