Claas’ new Jaguar 800 series self-propelled forage harvesters offer higher throughputs at reduced running costs.
First launched in 1972 and the world market leader, the Jaguar name has become synonymous around the world for high-output, cost efficient forage harvesting. A key feature to the success of the whole Claas 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.
The new Jaguar 800 adopts a rounded style and retains the well proven direct drive system to all the main components and the straight crop flow through the forager, which progressively increases the crop flow speed through the forager from about 4.8m/sec as the crop enters the forager to 68m/sec as it leaves the accelerator.
A key feature of the new Jaguar 800 series is the change to Stage IIIB compliant Mercedes engines fitted with SCR catalytic converters. The 400hp Jaguar 840 and 455hp Jaguar 850 have straight-six, 12.82-litre engines, while the 510hp Jaguar 860 and 598hp Jaguar 870 have 15.93-litre V8 power units.
A noticeable benefit of these engines is their high torque at low engine speeds. As a result, operators of pre-series machines operating in the UK last season found that they have been able to achieve considerably higher throughputs and lower fuel consumption compared to previous similar sized Jaguar 800 models. Fuel savings of 8-10 lit/hr have been achieved by Stage IIIB machines test machines compared to Stage IIIA machines in the same field.
An additional new option on the Jaguar 870 and 860 is the availability of Dynamic Power, which in DLG trials has resulted in fuel use savings of 12.3 per cent. As the crop volume through the forager varies, Dynamic Power automatically varies the engine power output over an 11-step range from just 272hp up to 510hp on the Jaguar 860 or 598hp on the Jaguar 870, while ensuring that the engine can maintain its optimum engine speed of just 1,800rpm.
The Jaguar 800 range also features a new continuous high-pressure hydraulic system that operates at 210 bar and which uses larger diameter hydraulic lines, so ensuring increased capacity and rapid hydraulic reaction times.
For the operator, the new Vista cab is not only more spacious but also has increased visibility. Setting up and operating the Jaguar 800 has been simplified thanks to an updated version of Cebis, which incorporates a number of new features designed to provide easier, faster and more intuitive operation.

Key function screens can now be quickly accessed using either the main rotary switch or the new Hotkey that provides direct access to pre-selected functions. Also, Cebis incorporates a night mode making it easier to read whehn working at night. The operator also 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 Quantimeter throughput monitoring, a reminder can also be set after a set yield quantity has been harvested.
To make the most of its high-capacity potential, the Jaguar 800 range is fitted with a new front attachment drive 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 the option of the Stop Rock detection system, the crop is fed into the well-proven V-Classic 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 specification Multi Crop cracker.
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’s 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 either 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.
The standard specification also includes a larger 1,000-litre diesel tank and 130-litre AdBlue tank, and as an option an additional 300-litre diesel tank is available. In addition, there’s an option for a comprehensive lighting system including Xenon main lights, an on-board 600 lit/min, 9.5 bar air compressor. There’s also a new 375-litre silage additive tank with a new higher-capacity additive pump allowing up to 2 lit/t of additive to be applied.
With the introduction of these four new Jaguar 800 series models, this means that Claas still provides the largest range of self-propelled forage harvesters, with two specification levels with Profistar and Speedstar to suit differing operator requirements.
