Problems solved by technology

While Cobb et al. may have provided advantages over then-current state-of-the-art, there is still much room for improvement
Furthermore, features necessary to enable the functionality of the cutter head, such as hydraulic actuators, can add significant cost, complexity and maintenance requirements to the machine

Embodiment Construction

[0020] refer to figure 1 , which shows a dozer blade assembly 10 for an implement system in a tractor according to one embodiment. Assembly 10 may include dozer blade 12 having a front 13 , a back 19 , a first outboard wing 14 and a second outboard wing 16 . A forwardly located push plate 18 extends between the first outer wing 14 and the second outer wing 16 . Blade 12 also includes a first side plate 15 and a second side plate 17 positioned outboard of and coupled to wings 14 and 16 . A rearward plurality of push arm mounts 20, one of which is schematically shown, are positioned on the rear face 19 for coupling the assembly 10 to the push arm of the tractor. A plurality of tilt actuator linkages 21 are likewise positioned on the rear face 19 in a conventional manner. Blade 12 also includes an upper edge 22 and a lower edge 24 . A material molding surface 26 is located partly on push plate 18 and partly on each of wings 14 and 16 and extends from side panel 15 to side pan...

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.

Description

technical field [0001] The present disclosure relates generally to cutters for dozing blades, and more particularly to multi-piece cutter configurations for optimized dozing efficiency. Background technique [0002] Tractors equipped with dozer blades are used for many different purposes. Applications that most people will be familiar with include moving loose materials such as landfill debris, construction debris and dirt around construction sites. Such dozing activities are indispensable in forestry, waste disposal, building construction, and light to medium civil engineering. Small to medium sized tractors are commonly used in these industries. [0003] Dozing is also an integral part of large-scale activities such as mining and major civil engineering projects. In these ranges, rather than pushing loose material across a surface, a tractor equipped with a dozer blade is typically used to dig material from the substrate. In the rocky terrain typically encountered in o...
