  • Patent number: 11622492
    Abstract: A system and method are disclosed for cutting and increasing surface area of surface stubble material while contemporaneously cutting and aerating the soil. A discoidal coulter blade is configured with a plurality of circumferential teeth for cutting the surface stubble as well as reducing the downward pressure required for the blade to enter the type and depth of soil desired. The circular coulter blade is configured with a plurality of inserts oriented normal to the rotational movement of the blade as the blade cuts the soil. Each insert is shaped to aerate a specific type of soil anticipated by an operator. The inserts are positioned on the blade for desired impact with the soil and angled in placement on the blade to maintain the desired effect on the soil.

  • Publication number: 20210048064
    Abstract: An extended highspeed rigid hub (EHRH) combined with a specific double roller taper bearing and tapered head bolt coupled with a coulter blade create a coulter blade assembly of great strength which functions to minimize flex at the circumference of the coulter blade. The EHRH maintains inner as well as outer bosses which support both inner and outer attachment points for the taper headed bolts to provide rigidity to the coulter blade. The double roller taper bearing adds to the rigidity equation by mitigating axial as well as radial forces exerted on the coulter blade. The coulter blade assembly, when coupled as one element to an implement, creates a rigid furrowing device capable of precise furrow construction in many challenging soil conditions.

  • Patent number: 10844908
    Abstract: A concentrated high-speed rigid hub allows for heavier planters, high-speed planting and seeding devices in multiple and multiple challenging applications such as no-till, high cation exchange capacity (CEC) soils, compact soils, moist soils, high concentrations of stubble and or Bacillus thuringiensis (Bt) crops, and cover or green crops with massive structured root systems. The hub is made of one of high strength forging steel and medium carbon cast steel, whereby the hub lessons hub flexing, hub bending, cracking and premature failure. The hub comprises rigid, heavy duty deep bosses or gussets which increase structural strength and maximize the strength of attachment points adapted for either bolts or rivets attachment to a blade or object.

  • Patent number: 10820462
    Abstract: A system and method cuts and increases surface area of surface stubble material while contemporaneously mulching, tiling and aerating the soil. A discoidal coulter blade is configured with sharpened areas at the circumference for cutting the surface stubble as well as reducing the downward pressure required for the blade to enter the type and depth of soil desired. The sharpened areas include a first long bevel, a second shorter bevel and an optional opposite counter bevel. The first and second bevels aid in coulter blade lifespan ensuring a self-sharpened blade while the counter-bevel allows mating with a second coulter blade at a sharpened point.

  • Publication number: 20190261549
    Abstract: A system and method cuts and increases surface area of surface stubble material while contemporaneously mulching, tiling and aerating the soil. A discoidal coulter blade is configured with sharpened areas at the circumference and one or more inside bevel for cutting the surface stubble as well as reducing the downward pressure required for the blade to enter the type and depth of soil desired. The bevel aids in coulter blade lifespan, ensuring a self-sharpened blade, and allows mating with a second coulter blade.
