Trenching system
First Claim
1. A trenching assembly for use with a work machine to cut a trench, the trenching assembly comprising:
- a frame;
a blade cover attached to the frame,wherein the blade cover and the frame define a surface engaging member and a cavity;
a hub, attached to the frame such that a vertical position of the hub relative to the frame is moveable;
a blade, located substantially within the cavity and supported on the hub, wherein the blade extends beyond the cavity; and
a cylinder assembly operatively attached to the work machine and to the frame wherein operation of the cylinder assembly manipulates an orientation of the surface engaging member about three axes relative to the work machine.

Abstract
A system for uncovering and sealing a narrow trench. The system comprises several subsystems, including a work machine, a frame for providing a seal with the surface to be trenched, a saw blade, a vacuum system, a system for placing product, and a resealer. The blade includes rotatable tooth bits, which may be rotated and secured to create a blade for narrower or a wider trench. A removable cover and the blade are easily changeable. A surface engaging member on the frame is manipulated to maintain a seal with changing ground surfaces. Additionally, the vertical location of the blade within the frame is adjustable to create a deeper or shallower trench.
