ABSTRACT:
A soil sampling device adapted to be mounted on a motor vehicle. The soil sampling device includes a tubular probe which is operated by means of a hydraulic cylinder and piston. A mechanism linking the probe with the piston causes the probe to swing from a horizontal position to a vertical position and then to move vertically downward into the soil. Upon withdraw from the soil the probe is caused to move vertically upward until clear of the soil and then to swing to a horizontal position with the end of the probe adjacent a sample collecting container. A second hydraulic piston and cylinder serves to eject the soil sample from the probe and into the collecting container. The controls for operation of the device are adapted to mounted at the vehicle operator's station.
