3. PROPER AND INTENDED USE
1. Double-sided disc mower is equipped with Perfect Cut cutterbar. The mowing height
differences, depending on the inclination angle of the cutterbar are shown.
Mowing height depending on cutterbar's inclination angle.
„Perfect Cut” cutting bar
No tilt 3° tilt 5° tilt

 The rear mounted disc mower is intended to mow green fodder such as grass and alfalfa on
permanent grassland (pastures), on crop fields without rocks, and to form loose rows of cut
fodder. The pasture or field being mown should be even and best if prepared by rolling. In
the event there is a majority of tall grass, the first and second mowing should be done at a height
of 2.4" - 2.8", while with a majority of short grass, at a height of 2". The last mowing should be
done a little higher - at 2.8" - 3.1" from the ground.
 The rear mounted disc mower with tine/roller conditioner is intended to mow green fodder such
as grass and alfalfa on permanent grassland (pastures), on crop fields without rocks, and to form
loose rows of cut forage. As a result of the passing of the layers of the green fodder through the
flails or rollers, the grass stems are broken and a layer of wax is removed. This facilitates and
speeds up the drying process of the fodder by approximately 30 to 40%. The use of rollers is
especially recommended when mowing legumes such as alfalfa. Rollers are particularly
recommended for mowing grass legume such as alfalfa. The pasture or field being mown should
be even and best if prepared by rolling. This is especially true of mowers with rollers as they
tolerate rocks with a diameter of a few centimeters. If a larger stone is picked up, stop and
remove it as it could cause damage of the discs. With a majority of tall grass, the first and
second mowing should be done at a height of 2.4" - 2.8", while with a majority of short grass it
should be cut at a height of 2". The last cut should be done a little higher - at 2.8" - 3.1"from
the ground.
Note: Grass, which has not grown much should be mowed with zero angle inclination .
