我国早期生产的丰收-35、丰收-27拖拉机以其较好的性能曾经受到过广大农机手的欢迎。但其发动机油耗高,经济性能差,起动困难,特别是在冬季,有的机手不得不采取一些违章操作(如:拖动着火,点火起动,从进气管吹入汽油起动等),使发动机寿命受到严重影响。 Early harvest of our country -35, bumper harvest -27 tractors have been better than its performance has been welcomed by the vast number of agricultural machinery. However, the engine has high fuel consumption, poor economic performance and difficult start-up. Especially in winter, some aircraft drivers have to take some illegal operations (such as dragging the fire, starting the ignition and starting gasoline injection from the intake pipe) Life expectancy is severely affected.
