Modern farm tractors develop more power than they can effi ciently transmit to a high-draft tillage tool via the tires without adding addi tional weight. The additional weight causes increased soil compaction re sulting in poor aeration, lower water infiltration and drainage rates, reduced water-holding capacity, and greater mechanical impedence to plant roots. One method of reducing the require ment of high wheel weights is to re duce the draft of the tillage tool by transmitting power directly to the tool by a means other than drawbar pull. A promising method of transmitting this power is by mechanically moving a portion of the tillage implement in such a manner as to apply forces to the soil in a more efficient manner
