我厂在无产阶级文化大革命期间,设计、试制了PQX-1.4十四片和PQX-1.8十八片悬挂缺口耙。通过多点试验,于一九六七年通过鉴定、定型,现已成批生产。该耙适用于旱地的耕前灭茬、耕后碎土和水田旱耕碎土。也适用于橡胶林的管理和苗圃灭草。这两种耙实为同一机架,只是耙幅不同。可以根据配套动力更换长短不同的方轴,达到不同耙幅。该耙耙架用矩型钢管焊接而成,结构简单、坚固。
During the Great Proletarian Cultural Revolution, I designed and piloted PQX-1.4 and PQX-1.8 eighteen suspension notches. Through more tests, in 1967 through the identification, stereotypes, is now mass-produced. The harrow is suitable for dry land stubble before tillage, tillage and paddy soil after dry farming. Also suitable for rubber plantation management and nursery weed control. The two rakes are actually the same rack, but different rakes. According to the matching power to replace the different length of the square axis, reach different rake. The rake hardened rectangular steel pipe welded together, the structure is simple and strong.
