在战无不胜的毛泽东思想指引下,我厂在沈阳铸造研究所和一机部农机所的帮助下,试制成功了用稀土中锰球铁代替高锰钢铸造24片圆盘耙的重耙片。经过两年来在一些农场使用证明,一般使用寿命在1000～2000亩地,较用65锰钢铸造的耙片,耐磨性提高了1/3,成本降低了3/4,可为国家节约较多的钢材,深受贫下中农的欢迎。

With the help of the invincible Mao Tse-tung’s thought and the help of the Institute of Foundry in Shenyang and the Agricultural Machinery Office of a machine department, the trial-manufacture of heavy disc harrows made of rare-earth manganese iron ductile iron instead of high-manganese steel . After two years in a number of farm use proved that the general service life of 1,000 to 2,000 acres of land, compared with 65 manganese steel cast blade, wear resistance increased by 1/3, the cost reduced by 3/4, for the national economy more More steel, welcomed by the poor middle peasants.
