Abstract: The soil sampler of this invention is mounted on a wheeled vehicle and includes a frame having a pivotal mast which is movable between an upright position and a horizontally disposed position. An elongated, hollow soil probe is longitudinally movably mounted on the mast so that the probe may be inserted into the ground to collect a soil sample. When the sample has been collected in the soil probe, the probe is raised from the ground and the mast is moved from its upright position to its horizontally disposed position. The soil sample in the probe is automatically dumped from the probe when the mast has been moved to its horizontally disposed position. The soil sample is collected in a receptacle position below the probe with the receptacle being divided into at least two compartments. The soil sampling probe also includes means for indicating the true position of the soil surface.
