[0002] A rotary tiller is a tilling machine that is used in conjunction with a tractor to complete plowing and harrowing operations. It is widely used because of its strong soil crushing ability and flat surface after plowing. It can also cut up the root stubble buried below the surface, making it easier for the seeder to operate and providing a good seed bed for later sowing. When a rotary tiller is in use, it generally drives a single rotary tillage structure for deep plowing, resulting in multiple plowings at each location, thereby increasing the tillage effect. In addition, the rotary tiller blade generally does not have a depth adjustment function, which means that the depth of the tillage cannot be adjusted, requiring the replacement of different rotary tillage blades, reducing the rotary tillage effect.
