Hydraulic‐powered soil samplers speed and simplify the collection of soil cores and plant root samples. Unfortunately, the vehicle carrying a sampler often damages a large area of the crop surrounding a sampling site and compacts the soH surface. The extent of such damage often prevents the use of powdered samplers. An attachment linking a Giddings 1 hydraulic probe to a knuckle boom mounted on a 3‐t truck permitted removing soil cores from small field plots with virtually no damage to the crop or soil at the sample site (except for foot traffic). The objectives of this note are to describe and illustrate the attachment and present some examples of rapid, easy collection of soil cores that it provided. The hydraulic probe, when mounted at the end of a knuckle boom, was not restricted in any of its operations.
