Mowing excellence.
Perfectly coordinated.
Forage harvesting from CLAAS.
For daily grassland-based operations,
you need more than just robust
operational machinery; you need
technology that works and that is quite
simply a pleasure to work with –
reliable technology that works in
unison when the going gets tough and
when there seems to be no end in
sight. And what's more, you need
harvesting systems that piece together
seamlessly.
As a leading equipment manufacturer
of forage harvesting machinery,
CLAAS provides the ideal harvesting
chain for any farm or business size.
Our coordinated machines support
you in your day-to-day operations and
enable you to achieve optimal results
in forage harvesting.
DISCO 290 / 250 / 210
Professional mowing technology for
small tractors.
CLAAS in-line bar.
The DISCO 290, 250 and 210 are equipped with the triedand-tested CLAAS in-line mower bar, which enables you to
achieve working widths of 2.85, 2.45 and 2.10 metres,
depending on the model.
The mower bar housing, manufactured from high-grade
steel, lends the bar its solid, robust characteristics. Extralarge toothed gears and robust ball bearings ensure a long
service life and high functional reliability.
The indentation on the underside of the bar enables dirt and
other contamination to empty out to the rear. The bar is also
brush-cleaned by the stubble left behind. This helps avoid
crop contamination, resulting in a high forage quality.
4
Weight relief.
The stress exerted against the two halves of the mower bar
on the DISCO 290, 250 and 210 is absorbed by one of two
coil springs. The ground pressure is spread evenly over the
full cutting width by counterbalancing the mower with the
dual spring arrangement.
This enables consistent and continuous mower bar
suspension for optimal ground-contour following in
challenging harvesting conditions, which reduces frictional
resistance, protects the grass cover and ensures a clean
and consistent cut.
5
A clean and consistent cut.
The broad overlap of the cutting discs ensures a clean and
consistent chop quality. Together with the high conveying
power of the mowing discs, the grass is deposited cleanly
in a single swath.
Swath former.
The DISCO 290, 250 and 210 are equipped with a swath
former, which creates a track for the vehicle between the
standing crop and the mown grass. This enables clean
parallel tracking over the mown swaths to prevent forage
contamination. An additional swathing plate is optionally
available.
Reliable V-belt drive.
The elastic drive belt transfers the drive force evenly and
without load peaks, so protecting the tractor and mower
unit.

DISCO 290 / 250 / 210
A question of technology.
Convenient single-lever mechanism.
With just one control lever, the mowing unit can be raised at
the headlands or swung into transport position without
having to use the three-point hydraulic linkage or modify
basic settings. The mowing unit is lowered to the ground
evenly over its full width via the horizontal parallel lifting
function. The ground pressure when mowing always
remains even, and the cut clean.
Collision protection.
Overload protection responds immediately upon collision
with an obstacle. To continue driving, the vehicle need only
be reversed a short distance for mowing to resume. The
mower bar is thus protected at all times.
Wear skids / high-cut skids.
For high acreages, or on sandy or stony ground, wear skids
protect the mower bar and increase its service life.
High-cut skids can be used to increase the chop height of
the mowing unit by a further 30 mm. This enables the
mowing unit to be quickly adapted to varied crop types and
soil conditions.

DISCO 290 / 250 / 210
Simple and convenient.
Transport lock.
The mowing unit can be folded up for transport via a singleacting cylinder. A mechanical lock is also provided to secure
the unit in place during transport. This ensures that the unit
is held firmly in place should a hydraulic line rupture. The
fulcrum is located well inside the machine for a minimum
transport width.
Three-point mounting.
The lower link pins are fully adjustable for adjustment to the
track width of the tractor, enabling you to fully exploit the
chop width at all times. The open, inverted U-frame
mounting also guarantees best possible freedom of
movement of the drive shaft.
8
Maintenance made easy.
The wide-opening protective covers enable easy access to
all maintenance points.
Replacement of drive components.
The drive system's components can be replaced in no time
at all if necessary for maintenance and repair.
V-belt tensioning.
You can see if the belt needs tightening by looking at the
mark opposite the belt. If necessary, subsequent tightening
is possible via a hexagonal bolt.
Integrated tool box.
An integrated tool box offers ample space for all the
materials and items you need in the field, such as knife
blades and spanners, for instance.

DISCO 210 RC
Leafy crops such as alfalfa present particular challenges to
a mower. With the DISCO 210 RC with roller conditioner,
CLAAS offers gentle conditioning of sensitive crops.
The DISCO 210 RC is equipped with dual spirally meshed
rubber rollers, which crush the hard stalks and protect the
sensitive, nutrient-rich leaves.
Adjustment.
The rollers are protected against foreign objects by a spring.
The tension and the spacing between the rollers can be
adapted to the harvesting conditions. The swath plates can
be adjusted without the use of tools for a clean and welldelineated swath.
