<p>PURPOSE:To enable both tillage work and work for finishing soil in a cultivation bed in one stroke without causing insufficient pulling horsepower, by pulling a working machine for deep tillage mounted on a car body and a working machine for crushing soil while separately vibrating both with a vibrator. CONSTITUTION:An apparatus (A) for creating a cultivation bed consists of a working machine (a) for deep tillage, a working machine (b) for crushing soil, a vibrator (W1) assembled in a machine frame 2 of the working machine (a) for deep tillage to vibrate the working machine (a) and a vibrator 2 assembled in a machine frame 3 of the working machine (b) for crushing soil to vibrate the working machine (b). Operation is carried out by traveling a tractor (T) while operating the vibrator (W1) of the working machine (a) for the deep tillage and the vibrator (W2) of the working machine (b) for crushing soil. Surface layer soil of soil deeply tilled by the vibrating working machine (a) for deep tillage is finely crushed by tooth harrows 7 of the vibrating working machine (b) for crushing soil and leveled with a land grading plate 73 while being further finely crushed to form a cultivation bed.</p> |
