PURPOSE:To enhance the feedback controllability of blades by preventing the vibration of the blade of a motor grader by providing two cylinders for sidewards sending a draw bar at bilaterally symmetrical positions. CONSTITUTION:In the blade link mechanism of a motor grader, one end 12a of a frame 12 provided to the car body frame is connected with one end 15a of a draw bar 15 to support the blade 14 through a circle 13 with the interposition of a lift cylinder 10. The other end 12a of the frame 12 is connected through a tilt cylinder 11 to the other end 15b of the draw bar 15. The lower ends 12c and 12d of the frame 12 are connected with both ends 15a and 15b of the draw bar 15 through cylinders 16 and 17 for sidewardly sending the draw bar, thereby preventing the vibration of the blade. |
