吴春旺同志来信摘录机引五铧犁(L-5-35)是与东方红—54(75)拖拉机配套的。按照使用说明书规定,该犁可在土壤比阻小于1.3公斤/厘米~2的地块作业,最大耕深为27厘米。可是根据这个比阻和耕深计算,阻力为6142.5公斤,大大超过了东方红—75(?)档作业的牵引力(3600公斤)。而我场在实际作业中,也是把五铧犁拆成了三铧犁或四铧犁作业。这不是说明东方红—75和机引五铧犁是不配套的吗?另外,按技术要求安装的安全装置,不能进行正常作业,就是在一般的土壤上作业,也会被拉断,这又是为什么呢?
Comrade Wu Chunwang’s excerpts from the machine lead Wuhua plow (L-5-35) is with the Dongfanghong -54 (75) tractor supporting. According to the instructions, the plow can work in the soil with a specific resistance of less than 1.3 kg / cm ~ 2 and the maximum plowing depth is 27 cm. However, according to the specific resistance and plowing depth calculation, the resistance is 6142.5 kg, far exceeding the traction of the Dongfanghong -75 (?) File operation (3600 kg). My field in the actual operation, but also the five plow split into a three-plow or four-plow plow operations. This is not to say Dongfanghong -75 and machine lead Wuhua plow is not complete? In addition, according to the technical requirements of the installation of safety devices, can not be normal operation, that is, in general soil work, will be pulled off, which in turn Why?
