Calculation and analysis on capability of embedment and balance of synthesized left-turn driven disc plow

A solution was presented to?increase the ability of embedment and improve the balance of power driven disc plow in dry-land. It synthesized left-turn power driven disc plow and moldboard plow. The new plow need no tail-wheel that much simplified the structure. As a result, the overall weight of the new plow was reduced, and the cost on material and manufacture was lowered. By calculating the embedment moment of plow and the support area of lateral-force balance device upon the plow groove, results showed that the embedment moment of the new plow was enlarged 58.8%, and the balance capacity was enhanced 2-4 times. Thus it increases the plowing depth and fulfills the demand of general agronomy in dry-land.
