Arena Grader – Multi R – is an universal grader built on the basis of a harrow dedicated not only to professional riding grounds. This unusual device is perfect for surfaces with sand and quartz substrates, however, which do not contain any flizeline parts. The grader also allows equating fields, meadows, slopes, bumps, communication paths and other substrates requiring equation. The reinforced frame allows you to deal with the roots or larger stones encountered on the road. The harrow itself affects the ground level and collects stones and other undesirable substrates.
