Multi-functional crawler rotary cultivator (MT-IAM01/MT-IAM02) combines robot control technology with agricultural machinery technology, and combines engineering operation capability with agricultural machinery operation capability. It is specially designed for mountain agricultural production, and taking into account narrow agricultural production plots and large slopes in mountainous areas, uses a special transmission crawler type chassis, which is small in size and light in weight, and can well adapt to mountainous terrain; Taking the engineering machinery as the power platform, the agricultural operation implements such as cultivation, management and transplanting are modularized, which can be freely loaded and quickly replaced as required. It is used as an agricultural machinery during busy farming season and as an engineering machinery during the slack season, which improves the utilization rate and investment benefit of the equipment. The equipment is applied with robot control technology to switch between "Manned/Unmanned" driving modes, which greatly reduces the labor intensity of the operator, and has the characteristics of high adaptability, wide application, high efficiency and simple operation.
