A tile plow, including a pivot bolt, a frame, a shank including a bottom at a first end of the shank, a top at a second end opposite the first end of the shank, a height measured from the bottom to the top, and a male connector, the shank hingeably connected with the frame at the pivot bolt, wherein the pivot bolt is positioned, in a direction extending from the bottom towards the top, at 66.4 percent of the height or more.

An apparatus for forming a trench in a sea floor and/or displacing material on the sea floor is disclosed. The apparatus comprises a body and front skids mounted to the body for engaging the sea floor and supporting the body. The front skids are adjustable between a first mode, in which the front skids engage the sea floor, and a second mode, in which the front skids engage the sea floor adjacent the trench and at the trench walls.

Process to stop and/or prevent the spreading of peat fires consisting of: digging a trench in the periphery of the area of outbreak of fire or potential fire, filling the trench at least partially with a superabsorbent (co)polymer (SAP).

A bi-directional sled includes a support structure and a shroud assembly. The shroud assembly is supported to the support structure for pivotal movement about an axis extending through the support structure between a first orientation and a second orientation. The shroud assembly has a shroud with a first edge and a second edge opposite the first edge. With the support structure moving the shroud assembly in the first direction relative to material to be dredged friction between the shroud assembly and material to be dredged pivots the shroud and the first edge into a first orientation to contact material to be dredged. With the support structure moving the shroud assembly in the second direction relative to material to be dredged the shroud and second edge are pivoted into a second orientation to contact material to be dredged.

A tile plow, including a pivot bolt, a frame, a shank including a bottom at a first end of the shank, a top at a second end opposite the first end of the shank, a height measured from the bottom to the top, and a male connector, the shank hingeably connected with the frame at the pivot bolt, wherein the pivot bolt is positioned, in a direction extending from the bottom towards the top, at 66.4 percent of the height or more.

A ditch forming implement, for use with a working vehicle, has a frame for towing connection to the working vehicle and which supports a rotatable impeller member thereon for spreading soil in a laterally outward direction relative to a forward path of the implement. A driven pulley wheel is fixed to a rear of the impeller member for rotation together relative to the frame. A drive shaft assembly operatively transfers rotational drive from a power take-off of the working vehicle to a driven pulley wheel on the frame, to be subsequently transferred to the driven pulley wheel by a drive belt connected between the driven and drive pulley wheels.

A trenching tool including an elongated pole having a bottom end connected to an elbow construction. A hollow cylindrical tube is movably mounted to the bottom end of the elbow construction. The tube is opened on both ends allowing loading of and emptying material scooped from the trench. An adjustable connection secures the tube to the elbow construction.

A method and apparatus for installing a monitoring cable or other utility near an existing pipeline. An electromagnetic signal may be induced on the pipeline. Sensors disposed on an installation vehicle communicate with a processor to determine a distance and orientation of the vehicle relative to the pipeline. A plow or other digging tool opens a trench and installs the cable along a path disposed next to the pipeline within an acceptable distance range from the pipeline. The vehicle may be remotely or automatically operated.

A machine pushed trencher assembly includes a first plate that is triangularly shaped. A pair of second plates is coupled singly to and extends transversely from opposing sides of the first plate. The second plates are coupled to define a cutting edge. A fourth plate that is coupled to a base of the first plate is configured to couple to a front end of a machine. A second bar is coupled to the fourth plate and extends angularly above the second plates. A third bar is pivotally coupled to the second bar. An actuator is coupled to the second and third bars. At least one wheel is rotationally coupled to the third bar. The machine compels the cutting edge through a substrate to prepare a trench. The actuator positions the wheel so that it rolls on a surface of the substrate to control a depth of the trench.
