A ditch cutting and excavation spoil removal apparatus creates ditches and land contours while simultaneously removing excavation spoil from the banks of newly created ditches. The apparatus includes an excavation spoil collection box and an adjustable plow saddle that supports a plowshare. The spoil collection box has a vertically adjustable rectangular frame with an open front and bottom. The pivotally mounted plow saddle may be tilted upward and downward through the bottom of the excavation box frame for adjustment of the plowshare and, correspondingly, the depth of the ditch being cut. Excavation spoil is collected in the spoil collection box as the apparatus is moved along the ground surface and is removed by raising the spoil collection box.

An earth working implement has a main frame, a main blade supported on the main frame transversely to the forward direction, and two wing blades pivotally supported at opposing ends of the main blade for movement between forward and rearward projecting orientations. A tilt actuator controls angular orientation of the main blade relative to the main frame about a lateral axis. Two rear wheels support the rear end of the frame for rolling along the ground. A hitch arm extends forwardly from a pivotal connection of the main frame for connection to a towing vehicle so as to vary in angular orientation relative to the main frame independently of the main blade. Furrow openers in a laterally spaced apart row are movable relative to the main frame between a working position protruding below the cutting edge of the main blade and a raised storage position.

A trench scoop bucket that can be welded to, or otherwise integrally formed with, bucket that attaches to a tractor, front loader, or any other machinery that can operate a bucket. The trench bucket is attached level with the bottom plate of the bucket and slopes down to a depth to match the dimensions of a trench. The sidewalls of the trench scoop bucket extend vertically downward to match the depth of the trench, and a ramp plate slopes from the bottom plate of the bucket into the trench. Horizontal plates are disposed on either side of the ramp plate and attached to the sidewalls to provide structural support to the ramp plate. The horizontal plates are level with the bottom plate of the trench scoop bucket and can provide alignment of the ramp plate within the trench.

A seabed plow capable of over-the-stern release and retrieval is usable in any of boulder clearing, trench cutting and backfill modes. In its boulder clearing mode, the plow uses its skid in torquing configuration followed by moldboards to push boulders out of the path to be trenched. In the trench cutting mode, the plow uses the skid in the same configuration with its share and moldboards for initial trench depth and the same share and moldboards with moldboard extensions for increasing trench depth in subsequent passes. In the backfill mode, the plow uses its skid in trench-straddling configuration following a blade with a passage designed to discharge fragmented spoil directly onto the pipe being covered. Thus, a single plow can be reconfigured for all modes for release and retrieval to and from a relatively small vessel without use of heavy lifting equipment.

An ultra high-pressure liquid jet soil processing system of an agricultural implement is provided. The ultra high-pressure liquid jet soil processing system includes a frame, an ultra high-pressure liquid pump disposed on the frame, a set of ultra high-pressure lines fluidly connected to the ultra high-pressure liquid pump, and at least a first liquid jet soil implementation head and a second liquid jet soil implementation head fluidly connected to the ultra high-pressure liquid pump via the set of ultra high-pressure lines. The first and second implementation heads are configured to condition soil for seed deposition by generating a plurality of trenches.

A mobile machine includes a load carrying mechanism configured to carry a load of material during operation of the mobile machine at a worksite. The mobile machine includes a position detection system configured to determine a position of the mobile machine and generate a position output indicative of the position of the mobile machine. The mobile machine includes a measuring system configured to determine a measure of the load and generate a measure output indicative of the measure of the load. The mobile machine also includes a material movement tracking system configured to receive the position output from the position detection system and the measure output from the measuring system and, based on both the position and the measure output, generate a material tracking indicator indicative of movement of the load of material around the worksite.

A non-straight sensor array within a gravity field, within a surface and cyclically surrounding a medial axis. The sensor array includes rigid bodies holding gravimetric tilt sensors, the rigid bodies being connected by flexible joints. The flexibility of the joints is constrained to two degrees of freedom. The shape of the path, the surface, and the medial axis are measured in at least two dimensions, using the tilt sensor data and the geometrical constraints of the joints. The cyclical geometry permits simultaneous measurement of lateral and axial deformations in deployments varying from axially vertical to axially horizontal, as well as improved fit of the array to surrounding surfaces. The field of use includes geotechnical measurements of soil and civil structures.
