The spring tooth harrow is known especially for the spring tines which provide a vibrating action to help break up the soil. The springs also yield to rigid obstructions such as rocks, potentially alleviating excessive wear on the equipment, team and driver. This piece was used on the local Quilici Ranch.
Synonym for spring tooth harrow: drag harrow.
