Abstract

PURPOSE: To enable a reliable control of a blade even under a severe using condition, by performing a lift control and tilt control of a blade by finding a height and a tile angle from a rotation angle of a lift cylinder against the vehicle body.
CONSTITUTION: Rotation angles of two lift cylinders detected by rotary detectors 18 and 19 are added by an integrating amplifier 34 which puts out a mean value eh. Said value corresponds to the height of a blade. A signal of a lift tilt meter 27 is added to the signal for correction, a deviation e between said signal and a signal of a blade height setter 35 being found. The deviation e is added to an absolute value circuit 36 and a comparator 39. A signal from a triangle wave generator 38 is added to the comparator 39 whereat a deviation is found, the blade being controlled to be positioned at a set height by moving the blade vertically. A control of a right and a left angle is also performed in the circuit composition as described above by the use of signals from the rotary detectors 18 and 19 signals from a tilt meter 28 and a tilt setter 40.
