Abstract
A disc plow having a stump jump capability. The plow includes a frame and at least one trailing arm secured thereto. The trailing arm supports at least one concave disc thereon. In use, the concave disc attached to the trailing arm has a working position in which the concave side of the disc is inclined so as to be open to any approaching soil and, a release position in which the concave side of the disc is directed at right angles to a forward to rearward alignment of the plow.
Claims12
A disc plow capable of avoiding objects, comprising:
- a frame;
- at least one trailing arm secured to said frame;
- at least one disc having a concave side supported by said at least one trailing arm;
- a first pivot connection securing said at least one trailing arm to said frame, said first pivot connection having a plow axis extending transversely from a forward position of said plow to a rearward position of said plow;
- and
- a second pivot connection securing said at least one trailing arm to said at least one disc such that said disc is rotatable about a disc axis which is at right angles to a plane defined by an outermost circular perimeter of said at least one disc and passes through a center of said circular perimeter, whereby in a normal working position there is an angle of inclination of said disc axis relative to the said plow axis so that said concave side of said disc is inclined so as to be positioned to receive materials and in a maximum release position, said concave side of said disc is directed at right angles to said plow axis.
A plow, comprising:
- a housing having a front portion a rear portion, and a plow axis extending from said front portion to said rear portion;
- at least one trailing arm having a length;
- at least one disc having a front concave face partially open to said front portion when said plow is in a normal working position;
- wherein said at least one disc is pivotally connected to said trailing arm by a first pivotal support, and said at least one trailing arm is connected to said housing by a second pivotal support;
- and
- wherein an axis defined by a central portion of said at least one disc is positioned at an angle of approximately 60 degrees relative to said front portion of said plow and said length of said at least one trailing arm is such that as said at least one trailing arm rotates about an axis defined by said central portion of said disc, and said axis of said disc is approximately orthogonal relative to an axis extending from a front portion of said plow to a rear portion of said plow when said at least one trailing arm is in a maximal elevation position.
A disc plow, comprising trailing arms discs supported by a frame such that when said discs are lifted to a maximal extent, which is such that a lowermost portion of each said disc is at a height similar to the height of a lowermost portion of any other part of a most directly related forward portion of said frame, an axis about which the discs rotate is approximately perpendicular to said forward portion.
