[0002] A power platform is a self-propelled power machine used to tow and drive working machinery to complete various mobile operations, and can also be used as a fixed operation power. It can be classified into agricultural, industrial, and special-purpose types according to functions and uses; and into wheeled, crawler-type, boat-shaped tractors, and self-propelled chassis according to structural types.

[0003] In a crawler-type power platform, agricultural implements are usually suspended at the rear, and operations such as breaking the soil, plowing, and turning the soil in the field are carried out according to the suspended agricultural implements.

[0004] Existing power platforms usually cannot be used with a harvesting platform to realize the function of crop harvesting. The core technical problem lies in that when the power platform is equipped with a rotary tillage hitch, the hitch uses a rear-mounted structure to realize a towing operation, while the harvesting platform needs to perform a forward harvesting operation.
