Abstract: A system for uncovering a trench. The system comprises several subsystems, including a work machine and a frame for providing a seal with the surface to be trenched with a saw blade contained therein. The blade is supported on a hub which is slidably movable relative to the frame by operation of a linear actuator, which may be a hydraulic cylinder or the like. The vertical location of the blade within the frame is continuously adjustable to create a deeper or shallower trench. A monitoring system is provided to monitor the vertical location from an operator station.

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.

Abstract: An assembly for installation of a silt fence. The assembly comprises a cutting member, a silt fence guide, and a spool of silt fence material. The cutting member may be a plow blade, a trenching assembly, or another cutting means. A vibrator may be utilized to enhance the effectiveness of a plow blade. The silt fence guide may be a grab wheel adapted to place the silt fence material into an opened trench or other means. The spool of silt fence material is preferably adjustable to change a position at which the silt fence material contacts the silt fence guide. Preferably, a roller or similar means is used to compact the soil proximate installed fence. Alternatively, a second cutting member and a second silt fence guide may be utilized to cut another trench. A second spool of silt fence material allows simultaneous installation of two fences. The assembly may be adapted to cut a curved path behind a work vehicle traveling in a generally straight direction.

Abstract: A silt fence with configurable barrier sections. The silt fence comprises a plurality of posts mounted on or in the ground, a fence panel, an apron panel, and a plurality of configurable barrier sections. The fence panel is secured in a vertical position to the posts and has a fence toe adapted to be buried in the ground. The apron panel is attached to the fence panel and extends from the fence panel to rest on the ground. An apron toe is also adapted to be buried in the ground to prevent erosion. Each of the plurality of configurable barrier sections has a panel edge and an apron edge, with the panel edge attachable to the fence panel perpendicular to the length of the fence panel and the apron edge attachable to the apron panel perpendicular to the length of the apron panel. The configurable barrier sections may be flexible or removable, and may be positioned in a barrier position or a cleaning position.

Abstract: A trench digging machine is supplemented by a spoils removal conveyor mountable on a frame intermediate the trench digger and the powered vehicle which carries the digger so as to be readily removable and replaced by auger spoils removal for moving spoils laterally from the trench being dug by the trench digger.
