摘要

CIRCUIT DRIVE ASSEMBLY FOR A MOTOR GRADER, MOTOR GRADER, AND METHOD FOR OPERATINGLY CONTROLING A CIRCLE DRIVER COUPLED WITH A MOTOR GRADER FRAME. This exhibition provides a circle drive assembly for a grader. The circle drive assembly includes a circle element being rotatable about an axis of rotation, a first hydraulic cylinder and a second hydraulic cylinder to rotatably drive the circle element, and the first and second coupling mechanism. The first hydraulic cylinder has a first end coupled to the first coupling mechanism and the second hydraulic cylinder has a second end coupled to the second coupling mechanism. The first coupling mechanism and second coupling mechanism may be controllably moved between a fixed position and a non-fixed position. The first hydraulic cylinder rotates the circle element when the first coupling mechanism is in the fixed position and the second hydraulic cylinder rotates the circle element when the second coupling mechanism is in the non-fixed position.
