Abstract: A fluid drive system for vertical mixer tubs is provided. Rotational power from the power take-off of a tractor or other suitable vehicle is increased in rotational speed by an input gearbox. The input gearbox is, in turn, coupled to a fluid coupler that locks up when the input rotational speed reaches an optimum speed. The output of the fluid coupler is coupled to an output gearbox that reduces the rotational speed of the fluid coupler. The output of the output gearbox is connected to the drive mechanism of the mixer tub auger.

Abstract: An interference knife apparatus is provided for use with an environmental material mixer. The mixer includes a tub housing at least one auger with blades mounted on the auger flight. The apparatus includes a post rotatably mounted on the outer sidewall of the mixer tub. The post can include one or more knives extending therefrom. Rotating the post moves the knives in and out of the mixer tub through access slots extending through the mixer's sidewall. The combination of the knives and the auger blades provides a “scissors-like” cutting action for cutting the environmental material during auger rotation.

Abstract: An auger for a vertical livestock feed mixer having an open-top mixing tub is provided. The auger includes two flights to draw in feed components from the bottom of the mixer tub and move them to the top. The trailing edge of the upper auger flight includes an upraised portion to deflect feed components towards the sidewalls of the feed mixer. The leading edge of the lower auger flight includes a kicker plate on the topside of the flight to deflect feed components towards the centre of the auger.
