The invention discloses a walking operation mechanism of a walking device. According to the walking device, two manual variable pumps equal in discharge capacity are driven by the same engine at the same speed ratio, and then two hydraulic motors are driven and serve as power sources for left and right side walking driving. A speed operation rod and a steering gear are connected into a whole, the speed operation rod is swung, a left bull gear and a right bull gear meshed with the steering gear drive variable mechanisms of the double variable pumps to achieve variation, then the tow hydraulic motors are driven to accelerate or decelerate at the same time, and therefore the walking device linearly advances or retreats and accelerates or decelerates. The steering gear is rotated, the left bull gear and the right bull gear meshed with the steering gear can drive the variable mechanisms of the double variable pumps to achieve variation in the reverse directions, then the two hydraulic motors are driven to generate rotation speed difference, and steering of the walking device is achieved. According to the scheme, the walking operation mechanism is particularly suitable for a harvester and other walking machines adopting crawler belt pulling.
