  • Motor grader with high-lift and lock arrangement
    Patent number: 4852659
    Abstract: A blade lift and support system for a road grader is taught which is of simplified construction and improved geometry. According to one embodiment, the adjustment of the beam and associated grader blade is fully hydraulically controlled including locking of the beam in a desired position and maintaining the beam position by an hydraulic fluid lock. This preferred arrangement permits full power adjustment of the high-lift while the blade is in a lifted condition. The particular beam shape improves the position of the cylinders to effect positioning the blade for working.
