ABSTRACT:
A dammer having three legs with a foot on the end of each leg is towed behind agricultural cultivating implements. Each foot slides flat against the earth until the weight of the soil causes the dammer to rotate, at which time the dammer rotates one-third of a revolution dumping one dam and continuing to form another.
