Abstract
The present disclosure provides a circle drive assembly for a motor grader. The circle drive assembly includes a circle member being rotatable about a rotation axis, a first hydraulic cylinder and a second hydraulic cylinder for rotatably driving the circle member, and a first and second coupling mechanisms. The first hydraulic cylinder has a first end coupled to the first coupling mechanism and the second hydraulic has a second end coupled to the second coupling mechanism. The first coupling mechanism and second coupling mechanism can be controllably moved between a clamped position and an unclamped position. The first hydraulic cylinder rotatably drives the circle member when the first coupling mechanism is in the clamped position and the second hydraulic cylinder rotatably drives the circle member when the second coupling mechanism is in the clamped position.
