Abstract: There is disclosed a pulverizing assembly comprised of a pulverizing housing defining a pulverizing chamber having spaced-apart and vertically-disposed shafts rotatably disposed therein wherein flywheels are mounted on each shaft in spaced-apart relationship. Rod members are mounted between the flywheels and beater assembly is rotatably disposed on each of the rod members. Each beater assembly is formed of a tubular member having a channel of a diameter greater than the diameter of the corresponding rod member with an elongated and retangularly-shaped beater plate member mounted by arm members mounted to the tubular member wherein the beater plate member is parallelly-disposed and spaced-apart from the tubular member of each beater assembly.

Abstract: Tilling apparatus, particularly for deep ripping of the soil, adapted to be towed by a tractor having teeth for penetrating the ground, each tooth being hollow, having an unbalanced rotor housed therein adjacent its lower end, a motor mounted on the side of the tooth adjacent its upper end, and drive means housed in the tooth driven by the motor and operable to drive the rotor for causing vibration of the lower end portion of the tooth.
