摘要：
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 CEC soils, Compact Soils, Moist soils, High concentrations of Stubble and or 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.
