Abstract: Disclosed is an assembly for mitigating soil compacted by wheels or belts of a vehicle moving over soil and carried by the vehicle. The assembly operates with a series of blades affixed to a rotatable shaft and displaying an elliptical pattern. A hood confines about the top half of the blades and spans about the width of the assembly. A motor rotates the rotatable shaft. A mounting assembly mounts the assembly to the vehicle behind and in alignment with the vehicle wheels or belts. A cylinder assembly reversibly moves the assembly from a home position downwardly into compacted soil for its mitigation.
Abstract: A single pass ground driven tiller and seeder apparatus includes a support frame, an elongated drive rotor journaled transversely on the frame, a tillage assembly pivotally connected to the frame and formed by a pair of rearwardly extending bearing plates and having an elongated tillage rotor journaled thereto and extending transversely therebetween, and a firming roller journaled between mounting plates pivotally connected to the bearing plates. The drive rotor is rotated by ground contact as the apparatus is drawn along by a tractor. The drive rotor is drivingly engaged with the tillage rotor so that the tillage rotor rotates at a faster speed than the drive rotor. A seed metering mechanism is supported on the frame and deposits seed in front of the drive rotor. The tillage rotor breaks the soil and incorporates the seed into the soil, after which the firming roller firms the seed bed.
Abstract: A power tillage device is provided having a passive rolling coulter as the prime mover for a power tillage blade which is carried in the lead of the coulter on a transfer case mounted as a radius arm on the counter shaft. The tillage blade rotates in the opposite direction from the coulter and is designed for optimum efficiency for shearing and lifting soil from a furrow.
