In order to increase the performance of three working parts of this machine at the same time, it needs to increase its operating speed, 1MG11-200type compound paddy tiller consists of the mounted compound structure arranged the subsoiler with cutting edge at the front part and rotary-tiller without power in the middle part and curved tooth-beam harrow in the rear part, this be able to plough and harrow and level at a time. As operating speed increases in clay loam, the clod heaping occurs in the space of subsoilers, even fill up in the spaces. Therefore, during the working, it is one of important matter to found the optimum operating speed and subsoiler’s interval without clod heaping. In a field study conducted at MiGok co-op farm, Sariwon, Democratic People’s Republic of Korea, were tested for clod heaping quantity on different operating speed and subsoiler’s intervals for clay loam. Mathematical response model was built on clod heaping quantity relative to operating speed and subsoiler’s interval to found the operating levels without clod heaping. It was found that the subsoiler, while working in clay loam, should have operating speed 6.2km/h, subsoiler’s side interval 0.5m and subsoiler’s front-rear interval 0.46m for optimum level without clod heaping.
