ABSTRACT:
A mobile soil sampling device is mounted on the side of a vehicle such as an ATV or UTV and includes an upstanding frame member which is vertically movable with respect to the vehicle by means of a parallel arm linkage and actuator. A vertically disposed and rotatable auger is mounted on the frame member and is moved upwardly and downwardly with respect thereto through the use of a motor and pinion gear with the pinion gear engaging a gear rack on the frame member. The auger is rotated so as to dig into the ground to the desired depth with the soil sample being conveyed upwardly into a vacuum collection chamber with the soil sample being conveyed to a vacuum chamber mounted on the vehicle. A sample collection device is mounted beneath the vacuum chamber for receiving the desired soil samples.
