Abstract
A cutter for a dozing blade includes a middle, first, and second section, each defining a plurality of bolting holes for receiving bolts to mount the cutter in a service configuration upon a dozing blade. The first and second sections each define a greater face angle between digging and mounting faces which is about 20° or less, and the middle section defines a lesser face angle between digging and mounting faces. The cutter may be provided in a service package for installation in place of a used cutter in a dozing blade.
Claims14
A cutter for a dozing blade in an implement system of a tractor comprising:
- an elongate multi-piece body having a one-piece middle body section, a one-piece first outer body section, and a one-piece second outer body section, each including a proximal edge and a distal cutting edge;
- the middle, first, and second body sections each further including a front digging face, a back mounting face, and defining a plurality of bolting holes communicating between the digging and mounting faces;
- the middle, first, and second body sections each further including a length extending between a first and a second outboard edge, a width less than their length, and their proximal and distal cutting edges being oriented so as to define parallel line segments extending from their first outboard edge to their second outboard edge;
- the cutter further including a first and a second end plate positionable outboard of the first and second body sections, and the first and second end plates each having lengths which are less than the lengths of the middle, first, and second body sections;
- the bolting holes in each body section being spaced from the corresponding proximal, distal cutting, and outboard edges, and configured to receive bolts for mounting the elongate multi-piece body in a service configuration upon a mounting surface of the dozing blade, in which the mounting faces are positioned in a first plane and the distal cutting edges are positioned in a second plane transverse to the first plane;
- and
- the first and second body sections each defining a greater face angle between their digging and mounting faces which is about 20° or less, and the middle body section defining a lesser face angle between its digging and mounting faces, such that in the service configuration the digging face of the middle body section is less steeply inclined to the first plane and more steeply inclined to the second plane than the digging faces of the first and second body sections.

A dozing blade service package comprising:
- a replacement cutter for installation in place of a used cutter in a dozing blade of an implement system in a tractor, the replacement cutter including an elongate multi-piece body having a one-piece middle body section, a one-piece first outer body section, and a one-piece second outer body section, each including a proximal edge, and a distal cutting edge, and a first and a second outboard edge;
- the middle, first, and second body sections each further including a front digging face extending between the proximal and distal edges, a back mounting face, and defining a plurality of bolting holes communicating between the digging and mounting faces;
- the middle, first, and second body sections each further including a length extending between a first and a second outboard edge, a width less than their length, and their proximal and distal cutting edges being oriented so as to define parallel line segments extending from their first outboard edge to their second outboard edge;
- the cutter further including a first and a second end plate positionable outboard of the first and second body sections, and the first and second end plates each having lengths which are less than the lengths of the middle, first, and second body sections;
- the plurality of bolting holes in each body section being spaced from the corresponding proximal, distal cutting, and outboard edges, and configured to receive bolts for mounting the elongate multi-piece body for service upon a mounting surface of the dozing blade oriented obliquely to a horizontal ground surface, such that the mounting faces are oriented parallel to the mounting surface and the distal cutting edges are oriented transverse to the mounting surface;
- the first and second body sections each further defining a greater face angle between their digging and mounting faces which is about 20° or less, and the middle body section defining a lesser face angle between its digging and mounting faces, such that when mounted for service the digging face of the middle body section is less steeply inclined to the mounting surface and more steeply inclined to the horizontal ground surface than the digging faces of the first and second body sections;
- the middle, first, and second body sections each having a length extending between a first and a second outboard edge, and a width extending between the proximal and distal edges which is less than the length;
- and
- a packaging system securing the middle, first, and second body sections in a fixed configuration for shipping.
