[0001] The utility model relates to the technical field of agricultural tillers, in particular to an agricultural tiller. Background Art

[0002] An agricultural tiller is a machine used to loosen and till the surface of the field during agricultural production to facilitate later sowing operations.

[0003] When the tiller body is used to loosen the surface of the field during agricultural production, the motor on the tiller is started to drive the tiller blade to rotate, and then the mobile frame is pushed to drive the tiller body to move to loosen the field. In actual use of the tiller body, due to the different loosening depth requirements of different fields, the installation position height of the tiller body and the tiller blade on the mobile frame is usually fixed. When it is necessary to loosen the soil of fields with different depth requirements, it is necessary to replace the tiller body of different models, which can easily lead to a long preparation time before the loosening process, reduce the loosening efficiency, and make the tiller body less adaptable.
