In the course of working , ， the plow will make use of the shuttling method so that it can dig alternately either on the left or on the right . compared to the unilateral plow , it can improve the productivity because it can help leave off the soil 、 take from the consumed energy and reduce the empty journey . to meet the requests above , we will use a remote cylinder with both a small cubage and double functions , approximately designing the plow to be columniform and symmetric . after the experiment for a period in the field , we found that the most frayed areas had happened at the places of both plow shank and share and at the same time the base of the remote cylinder had ruptured suddenly 与单向犁相比，其优点在于：耕地无开、闭垄，地表平整，降低了耕后整地的能量消耗，减少了地头的空行程，因而大大提高班次生产率。为了满足犁体梭式作业的要求，我们采用了一只小容积双作用的液压油缸；同时对犁壁曲面的形状采用了近似圆柱形的对称设计。但经过一段时间的田间试验，我们发现：该犁犁胸部分的犁胫和犁铧上的犁尖在工作中磨损较为严重；主犁梁和油缸缸体的连接部分（即油缸底座）突然发生了断裂，造成整个犁体无法正常工作。
