Sensor for a Motor Grader

Abstract:

A motor grader may include a moldboard assembly movably connected to a main frame of the motor grader to move with respect to a plurality of dimensions. The moldboard assembly may include a blade having a lower cutting edge, an upper free edge, and first blade side, and a second blade side. The moldboard assembly may be adapted to pivot the blade by moving the upper free edge with respect to the lower cutting edge. The moldboard assembly may be adapted to change the cross-slope of the blade by moving the first blade side with respect to the second blade side. To determine the pitch and/or cross-slope, a blade sensor may be mounted to the moldboard assembly. The location of the blade sensor on the moldboard assembly may protect the blade sensor and allow the blade sensor to directly measure the pitch and/or cross-slope of the blade.
