A depth gauging adjustment mechanism includes a spring- loaded handle which pivots about a common axis with the depth gauging wheel arm on an opener assembly. The handle has two transversely located pins, and the back of the opener assembly has notches on a radius struck on the axis for receiving the pins. The wheel arm and thus the planting depth are maintained by the handle. Each handle position represents a different planting depth which can be adjusted easily with one hand by pulling the handle against the bias, repositioning the pins and then releasing the handle. The wheel arm is freely rockable downwardly from the depth adjusted position to facilitate handle movement when the opener assembly is raised from the ground-working position.
