    Abstract: A hydraulic control for an attachment on a work vehicle. The attachment is mounted on the chassis of the work vehicle and movable between a first position and a second position. A hydraulic cylinder is operable to power movement of the attachment. A fluid circuit communicates with the hydraulic cylinder and is configured to carry hydraulic fluid. A fluid reservoir is in communication with the fluid circuit. Accumulators that are in communication with the fluid circuit automatically store and release hydraulic fluid in response to movement of the attachment. A valve assembly controls fluid communication between the fluid reservoir and the fluid circuit in response to movement of the attachment to its second position.

    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 ground engaging surface 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 excavation apparatus is disclosed. The excavation apparatus includes a chassis having a length that extends from a front end to a rear end of the chassis. The chassis also has a width oriented perpendicular to the length. A boom is pivotally attached to the rear end of the chassis. A cutting component mounted to the boom. A shroud structure at least partially covers the cutting component. A source of vacuum is in fluid communication with an interior of the shroud structure for drawing air containing dust from the interior of the shroud structure. A filter filters the air drawn from the interior of the shroud structure by the source of vacuum. A dust barrier projects downwardly from the shroud structure and extends along at least a portion of a perimeter of the shroud structure. The dust barrier has a construction that is pervious to debris generated by the cutting component and that provides gradually reduced restriction to inward air flow through the dust barrier as the dust barrier extends downwardly from the shroud structure.
