PURPOSE:To permit exact ground levelling work to be performed even by unskilled operators by providing a means to execute a preset arithmetic procedure and a means to search for data table by using attitude factor as a variable. CONSTITUTION:A finish angle displayer is made up of working machines, a draw bar left and right-inclination angle sensor 9 or blade inclination angle sensor 19 as the first means 1 to search for attitude factor related to the attitude of a blade 1, a circle angle sensor 10 as the second means to calculate a narrow angle beta between locus drawn by the tip of the blade 1 and reference face on the basis of the attitude factor searched, and a meter 14 as the third means to display the calculated narrow angle beta as finish inclination angle theta. Then, an arithmetic unit 12 as a means to execute a preset arithmetic procedure and a memory 13 as a means to search for data table by using the attitude factor as a variable are provided to the second means. |
