Abstract

A combination of a wheel supported liquid manure tank having a rearward end and a liquid manure soil injection device secured to the rearward end. The injection device is mounted on the rearward end of the tank and is capable of being raised and lowered by hydraulic cylinders. A plurality of substantially parallel support arms extend rearwardly from the tank and have a disk rotatably supported intermediate the ends thereof. The disk is mounted at an oblique angle with respect to the forward line of travel of the tank, that is, the disk is inclined laterally from a vertical plane approximately 2 degrees and is skewed with respect to the line of travel approximately 5 degrees. The disk is adapted when engaging the soil to open a slit therein. A nozzle operatively connected to the tank has its lower end disposed immediately above the slit. A cleaning knife is secured to the nozzle adjacent the disk on one side thereof to engage the disk and remove particles of earth which might adhere to the disk. A rubber cleaning wheel with a lip thereon engages the opposite side of the disk for the same purpose. That wheel also extends rearwardly from the tank. A closure wheel is mounted on the rearward end of the support arm to rotate over the open slit to close the same.
