Header transverse and longitudinal profiling actuator and harvester with same

The invention provides a header transverse and longitudinal profiling actuator and a harvester with the same. The header transverse and longitudinal profiling actuator comprises a left push rod assembly, a right push rod assembly, a chassis, a header, a support and positioning assembly and a header chassis connecting assembly. The header transverse and longitudinal profiling actuator has the advantages that by controlling the energization of the upper electromagnet and the lower electromagnet of the support and positioning assembly, the opening and closing of an upper pawl and a lower pawl arecontrolled, and accordingly the header can move vertically along with the actuator, the power supply of the corresponding electromagnetic is cut off to release the corresponding pawl when the headerreaches an appointed height, ratchet shaft locking is achieved, and header inertia is eliminated to increase header stability; when the header needs transverse profiling, by cutting off the power supply of the upper electromag
