  • 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.

  • Patent number: 10624252
    Abstract: A disk blade has an outer perimeter, a first side wall, a second side wall, and a central hub. A plurality of fingers extend laterally at an angle ? from said first side wall. The fingers preferably comprise metal round bars curved to form part of an elliptical geometry inserted at a perpendicular angle to a vertical angle of said disk blade. The bars are arranged at locations equidistant around said disk blade and are disposed at a depth x from said outer perimeter of said disk blade. Preferably, the depth x is at least ?one (1) inch.

  • Patent number: 10506754
    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 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.

  • Patent number: 9320189
    Abstract: An add-on tillage system is adapted to be mounted on an agricultural device to enhance tilling ability. The add-on tillage system includes a tilling unit with a common tool bar having attached thereto a first set of a plurality of tilling tines or coulters adapted to produce deep grooves in a tilled field. Means are provided for adjusting spacing between the tines or coulters, tilling tines or coulters up and down as a group being loaded by spring force, compressed air pistons or hydraulically actuated rams. A first mount is adapted to receive a tongue with hydraulic operations for mounting to a tractor. A second mount is adapted to receive a tongue with hydraulic mount to an agricultural device adapted to be pulled by the tractor. The add-on tillage system tills surface soil for a clean appearance, providing improved rain/irrigation water absorption, eliminating water run-off and erosion.

  • Patent number: 8627898
    Abstract: A tillage system has a first set of deep tilling tines and a second set of shallow tilling coulter tines present in a number more than twice that of the deep tilling tines. The deep tilling tines till the field to a depth of about 5 to 12 inches at row planting locations, loosening the soil for easy plant growth. This deep grooving action builds mounds of soil at both sides of the deep groove which are cleared by a second set of shallow tilling curved coulter tines followed by a third set of plurality of rows of shallow tilling toothed coulters that till the space between grooves to a depth of about 1 to 4 inches, providing a water reservoir space and clearing plant debris. A last row of shallow tilling ruffled coulters are provided to mix and incorporate into soil plant debris and plant stocks, anchoring tilled soil.

  • Patent number: 8210552
    Abstract: A compression and torsion damping wheel suspension system is useful for damping compressive and torsional shock encountered by freewheeling front caster wheels of a professional landscape lawn mower. The freewheeling caster wheels are mounted with an offset from a vertical pivot axis attached to the lawn mower frame. The compression and torsion damping wheel suspension system comprises two tubes one having internal extending projections and the other having external extending projections The smaller tube is turned within the larger tube, leaving behind several spaces within which are contained four elastomeric elements. When the caster wheel rides over a rock or bump, the elastomeric elements are compressed, damping compression shock. Caster wheel resistance is felt; the elastomeric elements experience torsion and are damped, providing a smooth ride for the operator.
