with only one central tine fitted it can work as a subsoiler and upto maximum depth for breaking of hard pan even with 50hp tractor.
只装配一个中心尖头时,它可以被用作一个深耕铲,最大硬土破土深度甚至可与50马力的拖拉机相当。
the ways of reduction of draft force and energy saving of subsoiler were studied and a new method for reducing soil resistance by self excited vibration subsoiler was put forward.
系统地研究了「拖拉机-深松机-土壤」系统的动态特性,探讨深松机减阻节能的技术途径与方法。
the constructional feature for bulk subsoiler to form mole lies in that its working part has the form of trapezoid frame, and its base blade is extending forward and downward.
