COMPACT DISC HARROW
RUBIN 12
Deeper, faster and more intensive: Rubin 12
2
Compact disc harrows provided previ-
ously intense and homogeneous mix-
ing of soil and organic matter to a
depth of approximately 14 cm.
With Rubin 12, LEMKEN supplements
its range of compact disc harrows,
consisting of Heliodor 9 and Rubin 9,
with a new series, which can work in
up to 20 cm depth. The compact disc
harrow can operate on all soils in
areas, which were previously reserved
for cultivators. With its specially ar-
ranged large concave discs, Rubin 12 is
designed in particular for the incorpo-
ration of large amounts of crop resi-
dues.
Various rollers from the wide range of
LEMKEN rollers offer optimal crum-
bling, reconsolidation and leveling, as
well as precise depth control for differ-
ent soil and working conditions.
