为了早日实现华北山区、丘陵、平原旱作地区农业机械化,根据一机部的安排,在河北、山西省机械局组织领导下,由河北保定农机厂、山西雁北地区机械厂、山西原平县农机修造厂、山西省农机化所、一机部机械院农机所等单位组成了东方红-20履带拖拉机配套农具设计组,经过了两年多的时间,完成了两轮样机的设计、试制任务。并通过试验和生产考核,于一九七五年年底,分别召开了悬挂三铧犁、旋耕打茬机和液压推土铲的鉴定会,三种农具均已初步定型。 1L—325悬挂三铧犁悬挂三铧犁新产品由保定农机厂试制。该犁配有单铧幅宽为25厘米的犁体三个,适用于华北丘陵和
In order to realize the mechanization of agriculture in the northern mountainous areas, hills and plains in an early date, according to the arrangement of a machine department, under the leadership of Hebei and Shanxi Machinery Bureaus, Baoding Agricultural Machinery Factory of Hebei Province, Shanxi Yanbei Machinery Factory and Shanxi Yuanping County Agricultural Machinery Construction plant, Shanxi Agricultural Mechanization Institute, a machinery department of Agricultural Machinery and other units formed Dongfanghong-20 crawler tractor supporting tools design team, after more than two years, completed two prototype design, prototype tasks. And through the test and production assessment, at the end of 1975, respectively, held hanging three-plow plow, rotary stalker and hydraulic bulldozer Identification Society, three kinds of farm tools have been initial shape. 1L-325 hanging three-share plow hanging three-share plow new product trial by the Baoding Agricultural Machinery Plant. The plow is equipped with a single plow width of 25 cm plow three for North China hills and
