MOBILE VEHICLE FOR WORKING

摘要

PROBLEM TO BE SOLVED: To eliminate the need for addition of an exclusively used sensor input part or a lifting and lowering control software when a wording implement is subjected to lifting and lowering control by using a working implement height sensor of a kind different from the existing one. SOLUTION: This mobile vehicle for working is obtained by converting a detected signal from a laser receiver 23 through a signal converter 26 into a detected signal having the interchangeability with a plowing depth sensor 9, inputting the resultant converted signal to an input part 12 for the plowing depth sensor 9 and controlling the lifting and lowering of the working implement 3 with a plowing depth automatic controlling means when installing the laser receiver 23 for detecting the height of the working implement 3 based on the received height of laser beans projected from a laser projector 24 in the working implement 3 in a tractor equipped with the input part 12 for the plowing depth sensor 9 for inputting the detected signal of the plowing depth sensor 9 and the plowing depth automatic controlling means for automatically controlling the lifting and lowering of the working implement 3 based on the detected signal inputted from the input part 12 for the plowing depth sensor 9 in a mobile machine body 1.
