Claas updates Jaguar foragers

With the implementation of Stage 4 compliant emissions standards across its range of self propelled forage harvesters, Claas has also taken the opportunity to include a raft of updates. James Rickard reports.

Updates for 2016 Jaguar models include new cracker roller options, re-vamped whole crop headers, a new tyre pressure control system and the introduction of Cmotion control.

 

Using selective catalytic reduction (SCR) technology to clean up exhaust emission, along with new, in-line six-cylinder engines for 840 to 960 models, all Jags now fulfil Stage 4 emissions standard.

 

The two most powerful models, the 980 and 970, are however not covered by any emissions regulations due to their engine power of over 760hp. They have therefore retained their V8 and V12 engines from MAN.

Dynamic Power

Following on from the introduction of its Dynamic Power, automatic power management control on its 860 to 980 Jaguars, the firm has developed it further with the introduction of extra modes.

 

Currently, as the load on the engine varies, for instance when working in lighter crops, this is automatically recognised by the engine management system which will alter the engine power output accordingly over 10 power steps from 272hp up to 510hp on the 940 or up to 884hp on the 980.

 

In addition, the driver can now select from one of three engine power setting; maximum power, high power and normal power. On top of this, the machine will now always drive into the crop at maximum engine power (stage 10) and only then does the system adjust the engine to the most efficient setting.

 

It is claimed the system can achieve fuel savings of up to 10.6 per cnet when the engine is put under partial load of between 1,800 – 2,000rpm.

 

Tyre pressure control

Tyre pressure control

Having already offered on-the-go tyre pressure control for the Jaguar’s front axle, now the firm offers this as an option on the rear axle.

 

Before using the machine, the driver sets the corresponding tyre inflation pressures – once for the drive axle tyres and separately for the steering axle tyres.

 

During machine usage, the pre-programmed air pressures are automatically adjusted depending on the position of the road travel switch, with the system automatically setting higher pressures for the on-road setting and lower pressures for the field setting.

 

 

Multi Crop Crackers

Until now, the Claas range of cracker rollers for maize silage has included the MCC Classic (with medium or large roller diameter) with saw-tooth profile for short-cut silage with chop lengths of 4.0-12mm.

 

The firm is now expanding its range with two additional cracker roller profiles for long-cut maize silage. For this, new MCC Max rollers have been developed for conditioning maize silage with chop lengths of between 15-22mm.

 

Also new to the range, for use with maize with a chop length from 26-30mm, is the MCC Shredlage cracker roller option (pictured). In addition to the saw-tooth profile of the rollers, these feature a counter-rotating spiral groove, for more intense crop processing.

 

Cmotion multifunction lever

In future, all Jaguars will be operated using the firm’s Cmotion multifunction lever, as found on its combines and tractors, and can be used to control up to 13 machine functions.

 

Its introduction follows Claas’ aim to achieve one operating concept for all its driven machines.

 

Cruise Pilot

Initially launched on its Lexion range of combines, then subsequently on its top model Jaguar 980, Claas is now offering its automatic speed control system on six further models; 860, 870, 940, 960, 960 and 970.

 

Designed to help achieve maximum engine operating rate and efficiency while at the same time reducing stress on the driver, Cruise Pilot works by automatically varying the forward speed of the forager based on throughput volume and engine operating rate.

 

To use, a desired target engine speed is programmed into the Cebis terminal. From this point, the forager continuously tries to drive at the specified engine operating rate. For example, if the crop density increases, the vehicle speed is automatically reduced.

 

The operator can also choose two other types of cruise systems to use based on a constant vehicle speed or constant throughput.

 

Direct Disc 500 and 600 wholecrop headers

Direct Disc 500 and 600 wholecrop headers

Using technology taken from its new Max Cut mower beds, the manufacturer has implemented its knowhow to its range of wholecrop disc headers.

 

The new Direct Disc 500 and 600 wholecrop headers feature cutting discs positioned very close to the front of the cutterbar, designed to produce a clean stubble, says the manufacturer.

 

A new, larger diameter auger has also been introduced to cope with more material and be better suited to tall crops.

 

Lateral knives are also available for harvesting crops with a high level of intergrowth.

 

To allow engagement at high speeds and to reduce stress on drive lines, the headers get a new, two stage start up procedure, with the intake augur activated first followed by the cutterbar.
