The adjustable ridger will create ridges and furrows in previously cultivated ground.
The ridger consists of a "V" shaped body that penetrates the soil to break up the surface. The furrow is created by the two adjustable mouldboards which are hinged to the body and so push the earth off to the side.
The adjustable ridger will create furrows up to 385mm (15") wide.
It fits to the power unit via a toolbar and so relies on the traction of the power unit to pull it through the ground.
See also the trailed ridger, which fits into the back of the rotavator.
