  • Patent number: 5183119
    Abstract: An anti-snag plowing system suitable for clearing mines in the Middle East is disclosed. Advantageously, the plowing system has also been found to be an efficient and effective soil conditioner, making it a useful farming tool as well. The plowing system comprises several digging-knife units, or plows, and a harrow. Both are attached in tandem to a chain matrix, which is pulled with either a helicopter or tractor. The digging-knife units rotate if the digging-knives hit an immovable snag. The harrow is covered with a chain blanket, and may have magnetic or sonic wave mine triggers if the system is used for clearing mines. A symmetrical embodiment is also disclosed.

  • Patent number: 4633955
    Abstract: A digger for root crops, such as peanuts, includes two or more digger units depended from a frame drafted by a tractor. Each digger unit includes a screw conveyor, a guide pair helically wrapped 180.degree. around the screw conveyor, and a hydraulic motor to rotate the screw conveyor. Stem and leaf portions of the plants extending above the bed surface are engaged within and moved rearward by flights of the rotating screw conveyor. The stems slide within the helical guide slot, which lifts the peanuts from the soil, moves them outboard of the conveyor, and inverts the plants above the conveyor. The conveyors are angled to the direction of draft so that the inverted plants are discharged from the slots in a windrow on the center furrow between the dug beds. A roller between the conveyors forms a mound or hill in the center furrow to elevate the windrow above standing water.
