Based on shape and function, rotary tiller blades can be divided into three categories: curved blades, straight blades, and chisel blades. Curved blades are suitable for soft soils; their curved design effectively reduces resistance and prevents weeds from tangling. Straight blades are more suitable for hard soils, achieving deep tillage through vertical cutting. Chisel blades are used to break up clods and stubble. In terms of specifications, blade length is typically between 15-30 cm, thickness is 3-8 mm, and mounting hole diameter varies depending on the model, with standard sizes such as 16 mm and 20 mm.
