The thing to use etc. are mentioned. The “attachment mechanism portion” means an attachment portion (hereinafter referred to as “chuck”) having a function of exchanging a drill blade.

(Work)
When plowing a field using a tillage attachment, if the portable power device is a portable electric drill, the drill and the tillage attachment are exchanged. When the attachment for tillage is previously mounted | worn as a tillage apparatus, the said operation | work is unnecessary.
Then, grip the handle of the electric drill (or both of the attachment-side handles if the tillage attachment has a handle), turn on the electric drill, and rotate the tillage attachment to place the tillage attachment in the soil of the tillage. Insert or plow from the surface of the soil.
The switch of the electric drill may be turned on after inserting the tillage attachment into the soil or after pressing it from the soil.

When the handle is provided on the attachment for tillage, the handle on the attachment side is more stable as a whole tillage device when it is positioned at the front side of the attachment for preventing the so-called swinging phenomenon during normal work. .
However, when plowing deep in the soil, the attachment side handle is moved to the electric drill side. As a result, the axial length of the tillage portion of the tillage attachment can be used for a long time, and the tillage can be deeply cultivated.

By using a tillage device configured by combining a tillage attachment and a portable power device according to the present invention, finely crushed soil and tillage can be achieved, and a small field can be efficiently tilled. Therefore, the physical burden on the operator can be reduced.
In addition, the tillage attachment and the tillage device according to the present invention have a smaller and simpler structure than conventional power tillers, so that maintenance is easy.

  The tillage attachment is detachably formed, and the tillage device can be configured only by obtaining the tillage attachment and attaching it to an existing portable power unit. Therefore, when the portable power device is carried, the tilling device can be configured at a low cost. Even if you do not have a portable power device, cheap portable power devices have been sold at DIY stores in recent years, and even if you purchase a tillage attachment, It is possible to obtain it relatively cheaper than purchasing a machine.

By providing a handle on the tillage attachment, the tillage device can be firmly held by the hand not holding the portable power unit. In addition, since the so-called swinging phenomenon can be suppressed, safety is high.
Moreover, since the position of the handle can be changed in accordance with the work posture, the operation situation, and the user's physique, the handle can be moved easily during work.

  Unlike a power tiller powered by an engine or the like, a device that uses an electric portable power device as a power source for the power tiller does not generate exhaust gas and has a small load on the environment.
