为贯彻执行毛主席关于1980年基本实现农业机械化的伟大战略部署,加速实现山区、半山区的农业机械化,我厂在湖北农机学院等单位的协助下,自一九七四年开始研制郧阳—20拖拉机履带板,现已生产近百台套。从拖拉机先后二轮1500小时田间试验的结果来看,质量在不断提高,现使用寿命已达1700小时以上,取得了可喜的进展。通过实践,我们破除了迷信,解放了思想,为稀土镁球铁的扩大应用和20拖拉机的大上快上创造了有利条件。
In order to implement Chairman Mao’s great strategic plan for basically realizing agricultural mechanization in 1980 and accelerate the implementation of agricultural mechanization in mountainous and semi-mountainous areas, the plant, with the help of units such as Hubei Agricultural Machinery Institute, started to develop Yunyang- 20 tractor track shoes, is now producing nearly 100 sets. From the tractor has two rounds of 1500 hours of field test results, the quality is rising, the service life has reached more than 1700 hours, made gratifying progress. Through practice, we have got rid of superstition and liberated our thinking, which has created favorable conditions for the expansion of rare earth ductile iron and the rapid growth of 20 tractors.
