MOTOR GRADER SADDLE POSITIONING SYSTEM AND METHOD THEREOF
First Claim
1. A draft frame positioning system of a motor grader having a main frame, comprising:
- an adjustable draft frame configured to be moved to one of a plurality of positions;
a moldboard coupled to the draft frame, the moldboard being movable based on the position of the draft frame;
a saddle assembly coupled between the draft frame and the main frame, the saddle assembly comprising a first saddle arm, a second saddle arm, and a saddle top member coupled between the first and second saddle arms; and
a saddle positioning cylinder configured to move between an extended position and a retracted position, the saddle positioning cylinder being coupled to the main frame or the saddle assembly;
wherein, a movement of the saddle positioning cylinder induces movement of the draft frame to any of its plurality of positions.

Abstract
A draft frame positioning system of a motor grader having a main frame includes an adjustable draft frame configured to be moved to one of a plurality of positions and a moldboard coupled to the draft frame. The moldboard is movable based on the position of the draft frame. A saddle assembly is coupled between the draft frame and the main frame, and the saddle assembly includes a first saddle arm, a second saddle arm, and a saddle top member coupled between the first and second saddle arms. A saddle positioning cylinder moves between an extended position and a retracted position, and the cylinder is coupled at one end to the main frame or the saddle top member and at an opposite end to the saddle assembly. A movement of the saddle positioning cylinder induces movement of the draft frame to any of its plurality of positions.

11. A draft frame positioning system of a motor grader having a main frame, comprising:
-
an adjustable draft frame configured to be moved to one of a plurality of positions; a moldboard coupled to the draft frame, the moldboard being movable based on the position of the draft frame; a saddle assembly coupled between the draft frame and the main frame, the saddle assembly comprising a first saddle arm, a second saddle arm, and a saddle top member coupled between the first and second saddle arms; and a first saddle positioning cylinder configured to move between an extended position and a retracted position, the first saddle positioning cylinder being coupled at one end to the main frame or the saddle top member and at an opposite end to the saddle assembly; a second saddle positioning cylinder configured to move between an extended position and a retracted position, the second saddle positioning cylinder being coupled at one end to the main frame or the saddle top member and at an opposite end to the saddle assembly; wherein, a movement of the first saddle positioning cylinder is independent of a movement of the second saddle positioning cylinder; wherein, the movement of either the first or the second saddle positioning cylinder induces movement of the draft frame to one of any of its plurality of positions. - View Dependent Claims (12, 13, 14, 15, 16)

17. A motor grader, comprising:
-
a main frame; a draft frame adjustably coupled to the main frame, the draft frame configured to be adjusted to any of a plurality of positions; a moldboard configured to perform a grading operation, the moldboard coupled to the draft frame; a saddle assembly coupled between the draft frame and the main frame, the saddle assembly comprising a first saddle arm, a second saddle arm, and a saddle top member coupled between the first and second saddle arms; a saddle positioning cylinder configured to move between an extended position and a retracted position, the saddle positioning cylinder being coupled at one end to the main frame or saddle top member and at an opposite end to the saddle assembly; and a control system comprising a controller, a saddle positioning sensor, a first saddle arm sensor, and a second saddle arm sensor; wherein, a movement of the saddle positioning cylinder induces movement of the draft frame to any of its plurality of positions; wherein, the saddle positioning sensor is electrically coupled to the controller and is configured to detect a position of the saddle positioning cylinder and communicate the position to the controller. - View Dependent Claims (18, 19, 20)
