ABSTRACT:
The soil sampling assembly is designed to be detachably secured within the central recess provided in the moulded rear bumper of small pick-up type trucks and the like. A bracket supports a pair of spaced and parallel members and a cylinder support extends upwardly therefrom and is adjustable lengthwise relative to said members. The cylinder is pivotally supported in a trunnion at the top of the cylinder support and the piston rod is pivotally connected to a soil probe tube extending downwardly from the cylinder. The device is easily actuated from a simple hydraulic system either driven by the truck motor or by a separate source of power in the truck and is easily attached and detached from the truck when required.
