Vertical tillage system
View Patent ↗A vertical tilling implement to be pulled behind and agricultural vehicle having a number of gangs of fluted-concave disc blades, rolling baskets, and wheels connected to a main frame. As the vertical tilling implement is pulled, the fluted-concave disc blades move the soil in a direction lateral to the side of the blades as well as up. Meanwhile, the rolling bars aid in leveling the seedbed and crushing the remaining large pieces of soil. The vertical tilling implement reduces the amount of subsoil compaction and cuts through heavy residue making it ideal for use in the fall or in the spring.
