1. A ground working apparatus, comprising:
- a bridle assembly to secure a plow frame;
a plow assembly comprises a frame, and a runner and a plow tool each coupled to the frame;
a linkage assembly coupling the frame to the bridle assembly to secure a plow frame for movement of the plow assembly between raised and lowered positions relative to the bridle assembly; and
the runner and the plow tool depending downwardly from the frame to concurrently run over and plow, respectively, ground to be plowed along a plowing path ahead of the bridle assembly and the plow assembly, and the runner to run over the ground to be plowed to set the frame of the plow assembly at a fixed elevated position with respect to the ground to be plow.

Abstract
A ground working apparatus has a plow assembly including a frame formed with an attached runner and a plow tool. A linkage assembly couples the frame to a bridle assembly for movement of the plow assembly between raised and lowered positions relative to the bridle assembly. The runner and the plow tool depend downwardly from the frame to concurrently run over and plow, respectively, ground to be plowed along a plowing path ahead of the bridle assembly and the plow assembly, wherein the runner sets the frame of the plow assembly at a fixed elevated position with respect to the ground to be plow.

9. A ground working apparatus, comprising:
-
a bridle assembly to secure a plow frame; a plow assembly comprises a frame, and a runner and a plow tool each coupled to the frame; a linkage assembly pivotally coupled between the frame and the bridle assembly permitting movement of the plow assembly between raised and lowered positions relative to the bridle assembly; the runner and the plow tool depending downwardly from the frame to concurrently run over and plow, respectively, ground to be plowed along a plowing path ahead of the bridle assembly and the plow assembly, and the runner to run over the ground to be plowed to set the frame of the plow assembly at a fixed elevated position with respect to the ground to be plow; the linkage assembly comprises generally horizontal upper and lower links pivoted to the frame and the bridle at frame and bridle pivot points, respectively; an extension of the lower link extends forwardly of the bridle pivot point of the lower link away from the plow assembly; and first means coupled between the bridle assembly and the extension of the lower link applying a bias to the lower link urging the plow assembly toward the raised position away from the lowered position. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A ground working apparatus, comprising:
-
a bridle assembly to secure a plow frame; a plow assembly comprises a frame, and a runner and a plow tool each coupled to the frame; a linkage assembly pivotally coupled between the frame and the bridle assembly permitting the plow assembly to displace between raised and lowered positions relative to the bridle assembly; the runner and the plow tool depending downwardly from the frame to concurrently run over and plow, respectively, ground to be plowed along a plowing path ahead of the bridle assembly and the plow assembly, and the runner to run over the ground to be plowed to set the frame of the plow assembly at a fixed elevated position with respect to the ground to be plow; the linkage assembly comprises generally horizontal upper and lower links pivoted to the frame and the bridle at frame and bridle pivot points, respectively; an extension of the lower link extending forwardly of the bridle pivot point of the lower link away from the plow assembly; a bracket affixed to the bridle assembly near the bridle pivot point of the upper link; and a bridle spring coupled between the bracket and the extension of the lower link applying a bias to the lower link at the extension urging the plow assembly toward the raised position away from the lowered position and the ground to be plowed. - View Dependent Claims (17, 18, 19, 20)
