Since the first Jaguar self-propelled forage harvester was introduced in 1972, the Jaguar name has become synonymous around the world for high-output forage harvesting.

At this month's Agritechnica, Claas will be unveiling the latest Jaguar 800 series foragers, which comprise four models with power outputs from 400hp up to 598hp.

A key feature to the success of the whole Jaguar range is its powerful and efficient direct drive system, where all the main components are directly driven by the engine.

Allied to this is the smooth straight crop flow through the forager, which ensures that a high crop flow can be maintained for the least amount of power.

From the outside, the new Jaguar 800 adopts a rounded style similar to that used on the Jaguar 900 series.

However, underneath the new Jaguar 800 retains both the well-proven direct drive system to all the main components and the straight crop flow through the forager.

The operator benefits from a higher degree of comfort thanks to the latest Vista cab. The new design is more spacious, with reduced noise levels and increased visibility.

Central to the setting-up and operation of the new forage harvester range is an updated version of Cebis, which incorporates a number of new features designed to provide easier, faster and more intuitive operation. To access function screens, the operator can either use the main rotary switch or the new 'hot key', which provides direct access to pre-selected functions.

Also, when working at night, Cebis now incorporates a night mode making it easier to read. The operator also now has the option to be able to switch off some of the automatic functions and control these manually. Should they wish to re-engage these functions, this is simply done at the press of a button.

Another new feature on the Jaguar 800 range is the availability of more adjustment parameters for the knives and shearbar. Using Cebis, the operator can now set a reminder as to when the knives need sharpening or the shearbar adjusting after a set operating time has elapsed. On foragers fitted with throughput monitoring, a reminder can be set after a set yield quantity has been harvested.

One of the defining features of the Jaguar range is the simple, high throughput straight crop flow system which progressively increases the crop flow speed through the forager from about 4.8m/second as the crop enters the forager to 6.8m/second as it leaves the accelerator.

To make the most of this high capacity potential, the Jaguar 800 range is fitted with a new quick attachment coupler that allows the forager to use higher throughput header units from the Jaguar 900 range, including the heavy duty Pick Up 300 grass pick-up.

From the intake, for which there is also the option of the Stop Rock detection system, the crop is fed into the chopping cylinder.

For further crop processing, the Jaguar 800 can be fitted with either an Intensive corn cracker or, for the Jaguar 870, an optional higher throughput Multicrop cracker.

SAVINGS

The new Jaguar 800 range is powered by Tier 4i-compliant Mercedes engines fitted with an SCR catalytic converter. A particular feature of these engines is their high torque at low engine revs.

Claas claim initial indications from pre-series machines operating in Britain is that users have been able to achieve considerably higher throughputs and lower fuel consumption compared to previous similar sized Jaguar 800 models.

Claas engineers say fuel savings of 8-10 litres/hour have been achieved by some of the test machines when comparing the Tier 4i machines to the Tier 3 machines in the same field.

A new option on the highest powered Jaguar 870 and 860 is Dynamic Power, which was first introduced on the Jaguar 900 range.

Using Dynamic Power, as the crop flow through the forager varies, the power output is automatically varied over an 11-step range from just 272hp up to 510hp on the Jaguar 860 or 598hp on the Jaguar 870. By matching engine power to crop load, Claas reckons this can result in fuel savings of up to 10.6pc.

To cope with the higher potential throughput, the Jaguar 800 range also features a new continuous high pressure hydraulic system that operates at 210 bar, which uses larger diameter hydraulic lines, so ensuring increased capacity and rapid hydraulic reaction times.

To reduce driver workload, in addition to Opti Fill, which enables the spout to swivel over a range of 225 degrees with automatic return to the transport position, there is also now the option of Auto Fill. Using a 3D camera to determine the trailer body dimensions and fill depth, Auto Fill will automatically control the spout which considerably reduces driver stress, especially when working at night.

To further increase productivity, the Jaguar 800 range can be specified with the Claas GPS Pilot automatic steering system.

For data recording using Cebis, up to 20 job records can be stored at any one time and data can either be printed out in the cab or downloaded onto a data card for transferring to a PC.

In addition, the Jaguar 800 range can now also be fitted with Claas telematics. This allows a far wider range of machine setting and operating data to be recorded and stored online, and viewed using any web enabled device, allowing the forager to be remotely monitored, daily productivity to be analysed and overall seasonal performance data assessed.

SPECIFICATION

The standard specification also includes a larger 1,000 litre diesel tank and 130 litre Ad Blue tank and, as an option, an additional 300 litre diesel tank is available. Also, there is a comprehensive lighting system including Xenon main lights, an on-board 600 litre/minute 9.5 bar air compressor and a 350 litre silage additive tank with application rate determined by either throughput, moisture content or dry matter content.

The introduction of these four new Jaguar 800 series models means that Claas provides the largest range of self-propelled forage harvesters, with two specification levels with Profistar and Speedstar to suit differing operator requirements.
