said rotational axis of said second disk being oriented at a predetermined angle relative to the rotational axis of said first disk, said angle being such that the forward reach of said second disk is closely adjacent to said first disk, and such that said forward reach of said second disk is closest to said first disk slightly forward and near a bottom of said reach of said second disk;
said subframe includes an arm means extending generally in the direction parallel to said first disk, said arm means being horizontally pivotally attached to said frame means at the forward portion of said arm means;
a generally vertical standard attached to said arm means, said standard having said first and second disks attached thereto; and

Abstract
A fertilizer applying apparatus for agricultural row crops applies fertilizer at a predetermined depth and lateral distance relative to a row line. A castering pair of disks are sized and oriented to part the soil adjacent the row line in a manner which minimizes soil fracturing which distorts the seed bed.

14. Apparatus for applying fertilizer in the ground adjacent to at least one row line of seeds during planting by a farm implement moving in a forward direction, the implement having a planting mechanism for planting the seeds, said apparatus comprising:
-
a frame attached to one of the planting mechanism and the implement; a disk means pivotably mounted to said frame and comprising; a subframe having forward and rearward portions, said forward portion being pivotably attached to said frame and being at least horizontally pivotable about a pivot point relative to said frame; a substantially vertically oriented rotatable Coulter disk having a first predetermined diameter attached to said subframe, said disk being aligned directly behind said pivot point so that it cuts the ground substantially parallel to the row line during travel; a vertically oriented rotatable spreader disk having a second predetermined diameter smaller than said first diameter attached to said subframe, said spreader disk being located adjacent said Coulter disk and being oriented at an angle relative thereto, said angle being such that the forward reach of said spreader disk is close to the Coulter disk and is closest to said Coulter disk at a location slightly forward and near the bottom of the reach of said spreader disk, and the rearward reach thereof is spaced a further distance therefrom, thereby spreading the ground during travel; fertilizer applying means operatively connected to said disk means for communicating fertilizer into the ground between said Coulter and spreader disks near said rearward reach of said spreader disk; said Coulter disk having a plurality of spaced apart notches in its outside diameter, the depth of said notches defining a notch diameter that is approximately the same as said second diameter.

15. Apparatus for attaching an arm means to a frame means about a pivot point located at the forward portion of said arm means, the arm means having at least one ground engaging implement component attached thereto for performing an agricultural operation, the implement including a first disk substantially parallel with the direction of travel and a second disk disposed at an angle relative to the first disk so as to generate a torquing effect thereon during movement through the ground, said apparatus permitting limited pivotable movement of said arm means, said apparatus comprising:
-
a bushing means having an elongated body portion comprised of a resilient material and having a rigid portion firmly attached to said body portion; attachment means for attaching one of said body portion and said rigid portion to said arm means and for attaching the other of said body portion and said rigid portion to said frame member, thereby permitting only limited horizontal pivotable movement of said arm means relative to said frame member about said pivot point through resistance generated by said resilient bushing so that when said arm means is preset a predetermined amount from a straight orientation, the first disk runs substantially straight in the ground despite the torquing effect generated by the second disk. - View Dependent Claims (16)

17. Apparatus for applying fertilizer in the ground adjacent to at least one row line of seeds during planting by a farm implement moving in a forward direction, the implement having a planting mechanism for planting the seeds, said apparatus comprising:
a frame attached to one of the planting mechanism and the implements;
a disk means pivotably mounted to said frame and comprising;a subframe having forward and rearward portions, said forward portion being pivotably attached to said frame and being at least horizontally pivotable about a pivot point relative to said frame; a substantially vertically oriented rotatable Coulter disk having a first predetermined diameter attached to said subframe, said disk being aligned directly behind said pivot point so that it cuts the ground substantially parallel to the row line during travel; a vertically oriented rotatable spreader disk having a second predetermined diameter smaller than said first diameter attached to said subframe, said spreader disk being located adjacent said Coulter disk and being oriented at an angle relative thereto, said angle being such that the forward reach of said spreader disk is close to the Coulter disk and is closest to said Coulter disk at a location slightly forward and near the bottom of the reach of said spreader disk, and the rearward reach thereof is spaced a further distance therefrom, thereby spreading the ground during travel; fertilizer applying means operatively connected to said disk means for communicating fertilizer into the ground between said Coulter and spreader disks near said rearward reach of said spreader disk; the planting mechanism being provided with a pair of planter disks which open a V in the ground in which the planter plants seeds, and said spreader disk being on an opposite side of said Coulter disk from the planter disks.
