Abstract

PURPOSE: To enable the effective use of both surfaces of a blade as a working surface over the whole height, by a method wherein a front and a rear surface of a two-way blade are formed in a concave curve being most suitable for a push work and a pulling work, respectively.
CONSTITUTION: When a tilting mechanism 38 is tilted back to bring a two-way blade into a state as shown in a chain line 2A, a stop surface 46 of a first stop piece 48 makes contact with a first stop surface 40 of a stop lock 44 to prevent the further revolving, and an effective scraping work is conducted through the backward movement. Then, when the tilting mechanism 38 is moved forward to bring the blade 2 into a state shown in a 2B, a stop surface 50 of a second stop piece 53 makes contact with a second stop surface 42 of ths top block 44, and the blade 2 is prevented from the further revolving to perform an effective pushing work through the forward movement. If a first indication piece 54 coincides with a second indication piece 56, the blade is brought to a state shown in a 2C, and an effective pulling work takes place through the backward movement.
