我县机引四铧犁(用L—5—35五铧犁改装)的保有量约170多台。1981年春季备耕大检查中,我们对7个公社所属17个大队的40台四铧犁进行检查,几乎没有一台犁合乎技术标准,犁普遍变形,同年8、9两个月,农机区划组对13个土壤比阻测定点的13台犁进行检查,结果也是一样的。按照标准,四铧犁的耕幅应为140厘米,但13台犁的平均耕幅达161.3厘米,其中一台犁的耕幅达184.4厘米,比五铧犁的耕幅(175厘米)还要宽,造成严重漏耕。
My county machine cited four plow (with L-5-35 five -share plow conversion) holdings of about 170 units. During the spring 1981 plowing inspection, we examined 40 4-plow plows of 17 communes belonging to 7 communes. Almost none of the plows met the technical standards and the plows were widely deformed. In the same year 8 or 9 months, the farm machinery divisions Thirteen plows of 13 soil specific resistance test points were examined and the results were also the same. According to the standard, four-plow plows should be cultivated at 140 cm, but the average plow yield of the 13 plows is 161.3 cm. One of the plows has a plot of 184.4 cm, more than the plow (175 cm) of the five-plow plow Wide, causing serious leakage tillage.
