In order to reduce the working resistance of soil compaction and the problem of tractor tire caused by crop stubble, a kind of cultivating combined front-stubble-breaking, post-subsoil and rear-rotary-tilling was design based on single and combined work of cultivating machines, and the field test was carried out. The experimental results showed that 1ZQHF350/5 front-stubble-breaking, post-subsoil and rear-rotary-tilling combined cultivating could enhance the stability of the tractor. The energy saving was about 6.2% and the ratios of pulverizing soil and stubble-breaking were improved above 2.3% and 5.8%, respectively. The problems and measures were analyzed in the process of application and promotion, which provided reference for study of large agricultural implements.
