Straight and fast. The crop flow.


Maximum throughput with low power consumption.

An optimal crop flow is a major factor in determining the daily output. The crop flows in a straight line through the entire machine without any awkward angles. It makes no difference whether you are harvesting grass without the Corncracker or are working in maize silage with it engaged. The crop is accelerated further at each step and is centred increasingly by the chevron arrangement of the knives and accelerator paddles. This results in maximum performance with minimum power consumption and makes for highly reliable operation. The JAGUAR demonstrates this time after time: with outstanding results – measured in terms of fuel consumption in litres per tonne.

Powerful and reliable. The intake.


Robust rollers.

The intake roller drive in the JAGUAR is designed for extremely high performance. Six cutting lengths can be set as required. Robust compression rollers ensure an optimum crop flow. Additional wear bars reduce wear to the machine.

Hydraulic reverser.

The hydraulic reverser ensures a slow, controlled and sensitive reverse rotation. The crop is gently extracted from the intake. When used with the PICK UP, the roller crop press is raised automatically, and, if required, the auger as well. With incremental reversing, foreign objects are brought to the intake rollers, where they can be removed quickly and safely.


Sensitive metal detector.

The metal detection system installed in the front feed rollers locates any magnetic object in good time. The low-wear, quick-stop mechanism then stops the intake immediately. Thanks to the location display in CEBIS, the operator can quickly see where the magnetic metal object is to be found.


STOP ROCK stone detector.

A powerful and rugged intake drive is one thing, but full protection against foreign objects is another. The STOP ROCK stone detector increases the reliability of the JAGUAR. If it detects a stone in the swath, it stops the intake immediately. You can set the minimum stone size yourself – the sensitivity is conveniently adjustable from the cab using CEBIS.


The chop length can be doubled by equipping the V-CLASSIC cylinder with half-knives. The half-knives enable a very consistent crop throughput which is ideal when harvesting grass or maize for long chopping and SHREDLAGE®.

Precise and proven. The V-CLASSIC chopping cylinder.


Chevron-shaped knife layout.

The effectiveness of the 750 mm wide chopping cylinder in the JAGUAR is unique. The chevron-shaped knife arrangement produces a pull-through, guillotine cut with a minimum of effort. At the same time, the forage is guided towards the middle – this reduces wear and friction losses on the sides of the drum housing.

  • Robust design
  • Minimum power requirement
  • High throughput
  • Top chop quality
  • Excellent discharge

Fully automatic sharpening.

A precision chop and consistent chop quality are possible only if the blades are absolutely sharp. The sharpening of the knives is controlled from the cab.

As an option, you can also control the shear-bar setting from the cab. The shear bar does not need to be loosened for this operation; instead, the mounting block is pivoted and moves gently towards the chopping cylinder with the shear bar firmly fixed on top. Knock sensors register contact and set the shear bar accordingly.

Sharpening and adjustment of the shear bar should be carried out on the basis of the throughput quantity rather than at a given time of day. CEBIS can be configured to give a reminder when knife sharpening is required.


Demands on flexibility are growing. In addition to the proven INTENSIV CRACKER (M = medium roller diameter of 196 mm), CLAAS offers the flexible MULTI CROP CRACKER.

The key characteristics of the MCC are its rugged construction and its extremely well sealed housing. Its great advantage is its flexibility. The outstanding accessibility of the rollers allows them to be replaced by others quickly. The MCC system is available in two sizes: MCC CLASSIC M (M = Medium with a roller diameter of 196 mm) up to an engine output of 585 hp. And MCC CLASSIC L (L = Large with a roller diameter of 250 mm) which is also optionally available for the JAGUAR 870 with 585 hp.



The conventional MCC CLASSIC is equipped with the familiar sawtooth profile and operates as standard with a speed differential of 30%. This system is used successfully for harvesting short maize for applications such as biogas facilities, but also for the production of silage as feed for dairy cattle and for bull fattening. Other rollers with a different number of teeth are used in markets where there is a greater need for long-chopped maize silage. The required degree of silage processing is achieved by increasing the speed differential.



The MCC MAX rollers have been developed to process maize silage with chop lengths between 7 and 22 mm. They consist of 30 annular segments with a sawtooth profile. The arrangement and special geometry of the annular segments ensure that the crop is processed not only by crushing and friction, but also by cutting and shearing forces. This allows more intensive processing of the maize kernels and also produces a fibrous breakdown of the stalk fragments.

When compared with conventional corncrackers, the range of applications for the MCC MAX covers much greater chop lengths and types of dry matter, while still delivering very high-quality processing results. The MCC MAX provides contractors, machinery rings and farms with a new technical solution which allows them to meet the most diverse customer requirements for forage processing.



SHREDLAGE®, a technology which was developed in the US and for which CLAAS has now acquired the licence, is an intensive maize silage conditioning system in the extremely long chop length range of 26 to 30 mm. Operating with a speed differential of 50%, the SHREDLAGE® rollers have a sawtooth profile into which a counterdirectional spiral groove has also been cut. In this way, the MCC SHREDLAGE® is able to grind the maize kernels thoroughly and chop up the cob fragments completely.

Leaves are well shredded and the stalk material in particular is subjected to a lateral effect by the spiral groove which causes the bark to be rubbed off the stalk. At the same time, the soft inner core is split lengthways. The intensively "shredded" crop can be compressed very well as the structure of the processed material keeps any rebound effect to a minimum.


SHREDLAGE®  maize silage.

The intensive processing multiplies the surface of the chopped material many times, resulting in significantly improved bacterial fermentation during ensiling and, above all, during digestion in the cow's rumen. Trials conducted by the University of Wisconsin show that SHREDLAGE ® drastically increases the physical effectiveness of maize silage in the rumen while also improving the availability of the starch contained in all parts of the plant. As a result, the daily milk yield in the herds studied increased by up to 2 litres per cow. Furthermore, the rumen-friendly structure of the silage improved herd health.

A higher milk yield and improved livestock health are not the only benefits SHREDLAGE ® has to offer dairy producers. As the availability of starch is optimised, it is possible to reduce the quantity of feed concentrate used while obtaining a higher overall milk yield. It is also possible to limit or even eliminate the use of fibre supplements such as straw, thereby providing further scope for cost savings.

The right approach to crop processing.

Only as intensive as necessary – this principle should always be kept in mind. It also applies to the roller gap setting and the intensity of the chopped material processing. More intensive crop processing increases the amount of energy required by the JAGUAR. The additional harvesting cost this causes needs to be taken into account.

Dynamic and exceptionally accessible. The crop accelerator.


Acceleration the energy-saving way.

The accelerator is ideally positioned in the JAGUAR for optimum performance of its task of speeding up the crop flow and feeding the crop reliably. The chevron-shaped accelerator paddles centre the crop flow, thereby reducing the wear on the side walls of the discharge chute. As the crop flow does not have to negotiate any awkward angles, correspondingly little energy is required to move it.

For heavy crops, the clearance between the accelerator and the rear wall can be increased hydraulically by up to 10 mm. This results in a huge reduction in the amount of energy required. If, for example, very dry grass requires a high discharge rate, a very narrow clearance setting is required. This can even be set up in CEBIS while travelling and then applied automatically at the start of the chopping process.


Extremely fast removal.

CLAAS offers an easy solution for removing the accelerator when post-harvest cleaning is required or if it should prove necessary to replace wear parts. Two people can carry out the removal procedure in one hour.

Continuous and precise. Throughput measurement.


Throughput measurement with the QUANTIMETER.

By recording the deflection of the upper rear precompression roller, together with the intake width and intake speed parameters, the volume flow is measured continuously. Counterweighing is recommended in order to ensure the highest possible degree of accuracy (tonnes per hectare). Retrospective adjustment of the yield data obtained at the start of the job is possible. Retrospective calibration using a new calibration value allows counterweighing to be delayed until any point between the start and finish of the harvesting process.


Dry matter measurement with NIR sensor.

Continuous dry matter measurement significantly improves the accuracy of the current throughput measurement.

With 20 measurements per second, the near infrared sensor (NIR sensor) attains a very high degree of precision – ideal for the documentation of harvest data for further use.

  • Measuring range for grass: 24-65% dry matter
  • Measuring range for WCS: 24-60% dry matter
  • Measuring range for maize: 20-60% dry matter

Concentrated and precise. The silage additive systems.


Using additives to enhance silage quality.

Applying silage additives while chopping has become a standard service offered by professional contractors. You can carry up to 375 l of fluid in the standard-fit additive tank which is easy to fill. The mixed additive is sprayed straight into the crop accelerator.

  • Tank capacity of 375 l
  • Flexible filling and cleaning facility
  • Metering from 30 l/h to 400 l/h
  • Throughput based metering from 0.5 l/t to 2 l/t (up to 200 t/h)
  • Dosage on basis of dry matter possible
  • Sight tube for external level indication

The dosage is controlled via CEBIS. Furthermore, CEBIS informs the operator about the fill level of the tanks.


ACTISILER 20 for precise dosage.

There is currently a trend towards a reduced quantity and a higher concentration. The new, optional ACTISILER 20 has been designed specifically to achieve this high-precision task with a precisely metered quantity of concentrated lactic acid bacteria solution. The control of the dosage, the record of how much you apply and the monitoring functions are all easily managed using CEBIS.

  • Separate 20 l tank for highly concentrated lactic acid solution
  • Dosage is controlled via CEBIS: constant: 200 ml/h to 7500 ml/h; throughput-based: 10 ml/t to 30 ml/t;
  • Dosage on basis of dry matter possible

Both systems can also be used simultaneously.


The discharge spout. Modular design.

High strength and a low dead weight are the key characteristics of the discharge spout. The concentrated crop stream can be directed more reliably, minimising wasteful losses. The modular design enables the system to be rapidly adjusted to different working widths. Two extensions (M / L) allow operation up to a working width of 7.5 metres. The back of the discharge spout is entirely bolted: as a result, the top plates also function as wear plates.


OPTI FILL. Extremely user-friendly.

The OPTI FILL optimised spout control system makes management of the transfer process extremely easy. The wide swivel angle of up to 225° allows an optimal view of the transfer process. When the discharge spout is swivelled, the end flap is adjusted automatically so that the transfer process takes place parallel to the direction of travel. Two permanently programmed spout positions simplify the swivelling process at the end of the field, e.g. when chopping up and down along one edge of a field. Furthermore, the discharge spout can be returned to its parking position automatically at the touch of a button.

AUTO FILL. Right on target - now also to the rear.


AUTO FILL. Automatic filling of transport vehicles.

AUTO FILL is based on digital 3D image analysis. The system takes care of controlling the discharge spout for you.

NEW: AUTO FILL "Side Rear".

With the "Side Rear" AUTO FILL function, automated discharging from the forage harvester is now possible not only to the side but also to a trailer behind the forage harvester – perfect when starting chopping or dividing fields. In chopping start-up mode, you can easily choose whether you wish discharging to take place to the side or the rear. For automatic filling to the rear, only the desired impact point needs to be specified.
