Abstract
A coulter assembly for collecting soil samples from an agricultural field in one embodiment comprises an annular collection blade configured for penetrating soil to capture a sample, an annular cam ring configured for stationary mounting to a frame of an agricultural vehicle and comprising a cam track, a blade hub coupled to the blade for rotatably supporting the annular collection blade from the annular cam ring, and a movable sample collector mounted to the annular collection blade. The moveable sample collector is configured and operable for extracting a soil sample as the annular collection blade is rotated through the soil. The moveable sample collector in one embodiment comprises a piston mechanism including a cylinder and rod movably disposed therein which actuated by the annular cam ring to alternatingly open and close a collection end of the cylinder as the annular collection blade rotates through the soil.
