PURPOSE:To improve the agitating effect of soil, by a method wherein a claw is installed on a housing and in the direction of onward movement of the housing, a disk is secured in parallel to a horizontal rotary shaft, and L-arms are radially attached to a disk in a projecting manner. CONSTITUTION:After a claw 21 is turned perpendicularly to a ground by swirling a device body, installed to the forward end of an arm 19, centering around a pin 24 so that a device body is oriented approximately horizontally, the claw 21 is forcibly pressed in a ground and a base machine 18 is moved backward to dig over a ground. Thereafter, the machine 18 is moved backward, a disk 8 is turned to scrape off earth and a chemical layer by means of a long arm 9. In this case, the scraped-off earth lump is agitted within a space surrounded with a cover 20 by means of the long and short arms 9 and a square blade 11 to mix it with a chemical. |
