Moldboard Opener Patents (Class 111/126)
  • Patent number: 6591767
    Abstract: A method of stimulating root growth of seeds is disclosed in which seeds are treated with an effective amount of an aqueous ammoniacal ionic solution of metal alkanoates. Alkanoates having from 2 to 6 carbon atoms are preferred, with acetates most preferred. Metals selected from the group consisting of boron, calcium, copper, iron, magnesium, manganese, molybdenum, potassium, sodium and zinc are preferred, with zinc particularly preferred. In one embodiment, an aqueous ammoniacal ionic solution of zinc acetate is applied to seeds in-furrow. In another embodiment, seeds are treated with an aqueous ammoniacal ionic solution of zinc acetate prior to planting. In yet another embodiment, an aqueous ammoniacal ionic solution of zinc acetate is mixed with an insecticide and resulting solution applied to seeds in-furrow.

  • Patent number: 5448958
    Abstract: An apparatus that treats and/or fixes soil gases liberated during plowing. An upper portion of a plow blade comprises a detachable panel made from a catalyst metal and behind the detachable panel is an electric resistance heater. A compressed fluid hose and nozzle located proximate the upper portion of the plow blade supplies reactants which react with a soil gas in the presence of a catalyst and heat.

  • Patent number: 4834189
    Abstract: An improved row crop cultivator for use in minimum tillage applications is described. A plurality of ganged cultivating units are mounted on a tool bar adapted to be towed behind a tractor vehicle. Each cultivating unit comprises a frame which is supported on a pair of spaced-apart gauge wheels. Also mounted on the frame for rotation within the gap between the gauge wheels is a disk-shaped coulter blade which is configured to cut through crop residue and weed debris as the material being cut is held against the ground surface by the gauge wheels. This arrangement tends to prevent improper cutting known as "hair-pinning". Trailing directly behind the coulter blade is a middleworker comprising a narrow width shank depending from the frame and having a weld point on its lower leading edge and wing-like share blades flaring rearwardly and outwardly at a predetermined angle from the lower end of the shank.
