“When KRONE previewed the BiG X, it presented a fully new Forage Harvester
concept. The innovative features, for example – from to 1000 hp level or 14
rows that means more than a 10 meter (34'5") working width, and as standard,
road travel at 40 km/h (25 mph). Thanks to the innovative transmission with fully

points that distinguish this
KRONE development from the rest.
This is the heart of the head, a clean cut ensures that the crop
quickly re-establishes and guarantees more output from the field.
The XDisc has a one-piece Cutterbar that is fully welded for
maximum durability and the wedge shaped edge of the Cutterbar
protects the Sward/ Stubble from damage. The large cross-sectional profile of the Cutterbar reduces the ground pressure and compaction, helping a quicker regeneration of the crop.
The massive intake auger guarantees efficient feed of the crop
to the feed rolls. With a diameter of 90 cm (35"), the XDisc works
without plugging even in very tall crops. Another plus is that the
head is fully enclosed to reduce crop losses but access to the
head is made in seconds by the easy-to-open protective covers.
The satellite driveline throughout the
Cutterbar was a KRONE invention –
imitated by many. The advantage is a
smoother operation and a cleaner cut,
as the discs are further forward and
have more area and time to cut the
crop. More safety and money saving
features are built into the cutting discs.
For example, the blades can rotate
360° to help protect them from rocks
or foreign objects, if they hit anything
they can simply swing out of action.
Also, the blade holders can be individually exchanged instead of the complete disc assembly. The XDisc has
Brawn & Brains.
No time is wasted hooking on this head. Just one driveshaft and
the machine is good-to-go. The beauty of this head is the drive-line;
it is straightforward, strong and has safety is built-in, the Cutterbar
has an overrunning clutch and the auger has a star ratchet – period!
The transport trailer has a long wheelbase and runs on two axles.
This enables simple and fast coupling and uncoupling of the
XDisc cutting system for transport. There are no axles under the
frame that are prone to damage when unloading and loading. The
specially developed transport trailer ensures safe transport even at
40 km/h (25 mph) with an integrated braking system.

quality. That’s why the KRONE design is very unique within this
area. Six large-diameter pre-compression rolls – instead of the
customary four – provides higher levels of compression. This
means that the crop is cut more easily and is precisely delivered
to the Cutterhead. Due to the infinite variable hydraulic drive, the
chop length can be adjusted remotely from the driver’s cab and

The two outer pre-compression rollers are
stainless steel and are both covered with

there are wear liners that cover every

small but BiG difference of the BiG X.
Peace-of-mind! The metal detector is integrated in the front lower roller. Six magnets
ensure precise location of metal even at the outer edges of the intake throat; the sensing
range can be adjusted to meet your requirements and is continuously self-calibrating for
100% reliability. The distance from the metal detector up to the Cutterhead is a huge

How do you get the best possible forage quality and highest
possible throughput into one operation? A simple answer: Design
the best possible Cutterhead to include a large, efficient cutting process with an effective knife configuration. Here the BiG X sets new
standards: With a effective cutting width of 800 mm (31.5") plus a
weight of over 500kgs (1,200lbs) and a cutting frequency of your
choice: 11,000, 15,400, 22,000, 16,800 or 24,000 cuts/min. But lets
talk about the angles, the approach angle of the knives to shearbar
is a massive 11° and the departure angle of the crop under the knife
carrier is optimized for exact crop flow. This means the
Cutterhead has Brawn & Brains. These details
lower power consumption and increase
productivity levels, which stack up for
your daily operation. It has IQ built-in.
The knives are arranged in a chevron pattern, which has two large advantages, 1st
the crop is cut easier, 2nd it starts bundling
the crop together and thus improving the
crop-flow. The 11° approach angle of the
knives to the shearbar guarantees to cut
the crop easier – just like a pair of scissors.
Another advantage for you on the 28 and
40 knife Cutterheads you always have a
knife that runs behind the shearbar = pure
safety & pure smooth operation.
The floor beneath the chopping cylinder
has a major effect on the quality of cut as
well. The floor on the new ‘VariStream’ system is spring-loaded so it can give way
when large amounts crop are passing the
system. This way, the machine is not
struggling and operation is smooth at all
The design of the Cutterhead within
the BiG X have a large significance on
forage quality, crop-flow, low power
requirement and low fuel consumption. For example, the prefect departure angle of the crop from the knife to
the kernel processor or to the discharge accelerator ensures the crop is not
carried around again, but it is been
ejected at the right time, decreasing
wear and increasing throughput. The
heavy knives are each fastened with
five bolts to the knife holders – for
maximum durability, we cut crop NOT
corners. The knives have elongated
holes for quicker, faster and precise
fitment. This considerably reduces the
time required for adjusting or changing
knives. The fastening bars are design
to take the wear NOT the knife, after all
the job of the knife is cut the crop.
The 20-knife drum on BiG X delivers long
chop lengths, which are desired in some
countries. This drum is available as an option.
The 28-knife chopping drum is standard
specification on all BiG X models. Use half
this number of knives and the drum cuts
grass to the proper lengths.
The 40 knife Cutterhead is known as the
BioGas Drum within the BiG X 650, 800 or
in the 1000. The BioGas drum can guarantee you higher throughput and lower fuel
consumption of up to 16%* when operating at 5 mm (1/4"). Chop length range of 3.5
to 17 mm. This short chop increases the
output of the BioGas power plants as the
crop converts quicker into energy.

The X-Factor – Quality in Quantity
What is important is what comes out! Every Customer wants to
Chop Quality in Quantity
Very low Rates of OverLength Fractions
More Output from the Crop
work with the greatest possible cost effectiveness and to achieve
the highest possible productivity. KRONE listens to Farmers and
Contractors and that’s why chop quality is a design criterion of
the BiG X, Quality in Quantity! This is our philosophy at KRONE,
to listen closely on the market requirements and then letting
these requirements flow quickly into the design of our products.
Exceptionally Structured and
Uniform Forage Quality
That why the BiG X is called the ”Listening Forage Harvester”.
Chop quality is something we are very proud of – the BiG X has
proved it over and over again with its uniform chop. And not to
forget it’s massive output too.
Chop quality starts at the front: The chopping quality of a
Forage harvester depends on its harvesting head and feed of the
crop into it. If stalks are fed offset to the Cutterhead, this will only
deviate the selected chop length considerably. If the stalks are fed
to the Cutterhead in a longitudinal direction, the defined cutting
length can be maintained. These are facts, which speak in favor of
the longitudinal, inline flow of the EasyCollect.
You can tell the BiG X has an outstanding chop quality with the
uniform flow out of the Spout. As there is no leaves or over-length
fractions that normally deviate from the discharge. Also if you watch
the discharge you can see a rainbow color spectrum (yellow-greenyellow) the Corn stalks are being exactly cut longitudinally.
Hundreds of shakeout tests have
shown the BiG X is capable of achieving its claims. A very low rate of overlength fractions with exceptionally
structured and uniform forage quality.
Only one equation applies for professional Farmers here:
Better chopping quality
= > better Silage compaction
= > less secondary fermentation
= > better forage quality
= > more output from the crop.
A typical KRONE BiG X sieve sample: Only
0.1 % of over-length fractions (> 20mm) for
a set chop length of 9 mm. Even when the
chop length is set to 14 mm the over-length
fractions remains at only 0.6 %, far below
the customary 2 - 2.5 %. With KRONE you
obtain more structure in the forage but
without excess over-length fractions.
Secondary fermentation should also be
prevented even with long chop lengths.
The key is that the chopped fractions
are as uniform as possible without any
over-length fractions. But what is more
important is to focus on the chop quality
instead on the conventional thinking of
theoretical chop length. The BiG X delivers Precision Chopping.

intelligent machines. To achieve high productivity or chop quality
not only do you require horsepower but also user-friendly intelligent technology. For example to get the maximum output on the
Forager with have developed leading edge technology called
Self Protection Built-in
Active Ground Contouring
“ConstantPower” where the machine automatically adjusts its
ground speed to the engine loading. This relives the operator of
constantly adjusting the ground speed – allowing the operator to
relax and increasing the output of the machine even more. Built
into every BiG X is a self-diagnostic system that monitors everything and flags up problems before they turn into real problems.
This gives you more reliability and durability especially in peak
season, as time waits for nobody.
Yield measurement can be equipped
optionally. The “CropControl” system measures the volume of crop harvested by the
machine. This is instantly stored on the
onboard computer and if required can be
printed out, giving you more documentation. Also the inoculant been applied can be
controlled by the CropControl system.
Moisture measurement is also available for the BiG X. This gives you highly accurate, realtime readings of the moisture value of the chopped crop as it flows through the spout. This
can be accurately used in various crops like Corn, Whole-crop, Grass or Alfalfa.
ConstantPower keeps your output
constant and gives more power to the
operator. Simply dial in the wished loading on the engine and the ground
speed adapts automatically. Giving
you maximal output hour-for-hour,
day-for-day. Especially useful for those
long days, let this intelligent system
work for you. Let this advanced
machine advance even more.
Specifying the machine with the AutoScan crop maturity detection system
will boost output even further and save
more fuel.
A unique system: ConstantPower + AutoScan
= more throughput
= higher fuel economy
= better chopping quality

VariStream – The new crop flow system
VariStream: The revolutionary details of this system add a new
modification to the crop flow system. First up, 6 pre-compression rollers ensure a very steady flow of crops. Yet, that's not all.
The floor and the back plate of the chopping drum are springloaded to give way when large amounts of crops pass the
system to ease the crop flow and ensure quiet running even at
peak loads.
A good throw: The spring-loaded back
plate of the impeller drum ensures consistent unloading efficiency, also in inconsistent crop flows.
A clever system: The floor beneath the chopping drum is linked to the anvil of the
opposite knife. This way, the clearance between any one knife and drum floor is
always constant, because the floor is adjusted when the opposite knife is adjusted.

service work to be performed directly in the field. Access to
all working components like the feed rolls, Cutterhead, K.P.
and the accelerator is quick and easy.
What can you do in two minutes? With a BiG X 1000 you can harvest 14 tons of Corn or simply open out the feed roll cabinet,
giving you the easiest access available for knife and shearbar
inspection. Sharpening can either be activated from the cab or
externally. Plus you have sharpening stone counter letting you
know when it should be readjusted. This is real operating comfort
for the driver. For your convenience there is a working light positioned above the unit that aids sharpening in darkness.
The feed roll cabinet can be removed easily in minutes, two possibilities: on their own or with any head attached. This exposes the
Cutterhead and makes all components directly accessible. This
makes service work a pleasure, especially when changing knives
or the shearbar. A service cart is available either for the feed roll
cabinet or Cutterhead this allows you to remove the unit safely and
then maneuver the unit around the workshop.
As standard equipment is an integrated air compressor with a large tank. It
can be used for blowing down the
machine before sharpening or for
maintenance work. It will even drive
1/2" drive air wrenches thanks to its
large onboard air tank. This will be
appreciated for all types of fieldwork.
The engine is installed transversely over the rear axle allowing all
components to be directly driven, reducing power losses. Along with
the benefits of better weight distribution this also provides optimum accessibility for maintenance. By opening the large access
