为了适应广东省逐年扩大种植甘蔗的开沟需要,1976年初,广东省一机局给三水县农机研究所下达了开沟机的研制任务,要求用红卫-40或丰收-35为动力,开沟一次成形,沟形截面的面宽与深度均为70厘米的梯形。在佛山地区所和三水县农机三厂的协助下,经过三代样机的研制试验,性能达到了设计要求,1979年10月通
In order to meet the Guangdong Province to expand year by year need to expand the planting of sugarcane ditch, in early 1976, a bureau of Guangdong Province Sanshui Agricultural Machinery Institute issued a ditching machine research and development tasks, requiring the use of red Wei -40 or harvest -35 as the driving force, Forming a trench, the groove width and depth of the cross-section are 70 cm trapezoid. In Foshan and Sanshui County, three agricultural machinery factory with the assistance of the prototype after three generations of development and testing, performance has reached the design requirements, in October 1979 through
