Abstract

A plow includes a single horizontal blade adapted to plow deep below the earth to cultivate turnrows or other strips of a field having no crop growing thereon. The blade has about a 12° plow angle and is V-shaped with a 25° drag angle sweeping back on either side of the medial apex.

Claims

1. A turnrow plow adapted to be drawn by a farm tractor comprising:

a. a rigid frame,

b. a three-point hitch rigidly attached on the frame for attaching the frame to the tractor,

c. a V-shaped blade having

(i) two wings attached at

(ii) a forward apex,

d. an apex shank fixed to the frame and welded to the blade at the apex,

e. two wing shanks each fixed to the frame and to an end of the wings

f. each of the three shanks having a forward edge,

g. a knife edge on each of the forward edges,

h. said wings having

(i) a plow angle of about 12°

,

(ii) a drag angle of about 25°

,

j. said frame including a V-shaped frame member vertically over the V-shaped blade with a forward apex of the frame,

k. a back member connecting the rear of the V-shaped frame member, forming a triangle,

m. a hitch beam parallel to the back member and normal to the direction of draft attached to the apex of the V-shaped frame member,

n. the hitch beam attached by welded joint to the apex and attached by struts extending aligned with the direction of draft from each end of the hitch beam to the V-shaped member, and

o. three connection points attached to said hitch beam thus forming said three-point connection.

2. The invention as defined in claim 1 further comprising:

p. each wing includes

(i) a moldboard extending from the front shank to wing shank,

(ii) the moldboard having the same width as the shank, and

(iii) a plowshare extending along and bolted to the front edge of the moldboard.

3. The invention as defined in claim 2 wherein

q. said moldboards are attached to each of the shanks by a welded joint and each of the shanks is attached to the frame by a welded joint.
