Abstract

PURPOSE: To control loads at a blade by moving the blade up and down so as to mate detected value of actual output with set point conformed to maximum power to be determined by characteristic of each engine.
CONSTITUTION: A blade 13 is operated by a blade control means according to deviations of values detected by means of an output detector wherein actual output of an earth-moving machine is detected by multiplying both detected values outputted from a blade load detector consists of strain gauges 3 and a speed detector 4 from a required value of the earth moving machine output set up by means of an output setting up apparatus 6. The load on the blade is adjusted by moving the blade up and down with a blade motion switching means comparing revolution speeds outputted from both an engine speed setting up apparatus 16 for setting up an engine speed obtainable of said set up output and an engine speed detector 15 for detecting actual revolution speed, and the said detected value of output is controlled so as to be conformed to the set up output value.
