[0002] A rotary tiller is a commonly used agricultural machine, mainly used for tilling and turning the soil. It cuts the soil through rotating knives to achieve the purpose of breaking up soil clods, mixing fertilizers and planting crops. The knives of a rotary tiller are usually composed of several rows of rotating blades, which can be adjusted in depth to suit the soil with different planting requirements. Quick blade change is an important function in the operation of a rotary tiller, which refers to the ability to quickly replace damaged or worn blades. This is very necessary because the blades will wear out after long-term use. If they are not replaced in time, it may affect the efficiency of the rotary tiller and may even cause equipment failure or safety hazards.
