EasyCut - the ultimate cutterbar
Perfect and clean cuts are pivotal for high-quality forage. KRONE
mowers deliver perfect results. These high-quality machines are
strong, sturdy and absolutely dependable.
Better cuts:
The wedge-shaped and fully welded cutterbar provides perfect cuts
even in the most difficult conditions. For complete peace of mind, the
discs operate fully protected by the cutterbar, spinning on massive
double bearings to absorb peak loads in permanent operation.
Quick-change blades:
Quick-change DS blades (DS = double
safety) provide for easy and fast knife
change or replacement on the site.

Perfect in all conditions
KRONE disc mowers evolved from a sustained cooperation among farmers,
scientists and developers. The linkage system is compact, low in weight and
swings the mower through a large angle up and down, providing AM excel-
lent ground contour following and adaptation to hilly terrain.
Constant-velocity and high-power driveline:
Drive power flows through a frictional drive-
line of pto shafts and gears, a system that
warrants an efficient transfer of power from
the tractor down to the cutterbar discs - even
in difficult conditions.

Optimum treatment for optimum quality
Full-width conditioning:
Specified with V-shaped steel tines, baffle
plate, aluminium hood and optional deflector
plates, the conditioner spans across the
machine’s full work width. The design

and as narrow as necessary
Scientific research has shown that spreading has a significant
effect on fermentation and quality of the forage. Accordingly,
the hood not only spreads the

area but also produces
