ABSTRACT OF THE DISCLOSURE A soil sample core extraction tool having a handle member on which is movably mounted a soil probe member and a clutch arranged for selectively preventing movement of the soil probe with respect to the handle member. By sequential actuation and release of the clutch, the depth of the probe member into the soil being sampled becomes independent of the position of the handle member relative to an operator, thus permitting the operator to manipulate the handle member from a convenient position during the entire sampling operation. A cleaner is removably attached to the handle member for facilitating removal of a core sample from a sampling tube of the probe member and permitting subsequent lubrication of the sampling tube in order to eliminate resistance of the tube to insertion into a soil being sampled.
