Forage harvester updates target output, efficiency and operating costs
New model-year features include automatic knife-condition monitoring, discharge chute damping and two headers entering full production.
A series of updates for the 2027 model year is designed to improve harvesting performance, reduce operating costs and extend the capabilities of the Jaguar 1000 forage harvester range.
Claas has announced new functions including automatic knife-sharpness monitoring, live yield mapping and active vibration damping for the discharge chute. The 16-row Orbis 12000 maize header and Direct Disc 8400 direct-cut header, both introduced previously and tested in limited pre-series production during the 2026 harvest, are also moving into full series production.
The Jaguar 1000 range comprises four power classes from 850 to 1,110PS. Its design includes a crop-flow width of up to 910mm, fully hydraulic pre-compression and a V-Flex chopping cylinder, alongside front-mounted attachments designed for high throughput.
Knife monitoring aims to reduce wear costs
Cemos Auto Knife Condition uses two reluctance sensors mounted above the chopping cylinder to monitor knife geometry and assess sharpness across the blade width.
Operators set the required sharpness level and sharpening strategy through the Cebis cab terminal. The system then alerts the driver when sharpening is needed, rather than relying on fixed grinding intervals.
Claas says this should help maintain cutting quality while optimising fuel consumption and knife life. Blade wear can also be documented by individual field area through Claas Connect, giving contractors a record that can support the calculation and invoicing of wear-related costs.
Wider maize harvesting capacity
The Orbis 12000 has a 12m working width, equivalent to 16 maize rows at 75cm spacing. Compared with the standard 12-row model, the wider header reduces the distance travelled during harvesting by 33%, according to Claas.
Independent drives for the cutting and conveying discs and feed drums are designed to maintain chopping quality across different operating conditions. Cemos Auto Header can automatically adjust feed-disc speeds according to chop length, throughput or forward speed.
Ground tracking uses Auto Contour, with three sensors detecting ground irregularities and two actively controlled stabiliser wheels helping maintain the selected working height. The header folds for transport, with an integrated transport chassis and automatic protection system allowing a transport width of less than 3.30m.
The Direct Disc 8400 has an 8.41m working width and is designed for direct harvesting of whole-crop silage, including triticale, rye, sorghum and silphium, in crops up to 4.5m tall.
Two 4.2m Max Cut cutter bars operate with external drives and a mower-disc speed of 3,200rpm. A quick-change blade system is intended to simplify maintenance, while Safety Link modules protect the cutter bars from foreign-object damage.
Four ground-contour sensors support ground following across the header width. The 800mm-diameter feed roller has active hydraulic pre-compression, with two height settings and three rotational-speed settings to suit crop and harvesting conditions.
Improved discharge control
Active vibration damping for the discharge chute is fitted as standard to the Jaguar 1000 from the relevant model-year production. Sensors monitor chute position and vertical movement, with the control system adjusting the lift cylinder to compensate for movement.
The aim is to keep the crop stream aligned with the receiving trailer, including when harvesting across rows or filling at height. Claas says the system can support higher forward speeds, reduce driver fatigue and improve the performance of its Auto Fill wagon-filling system, while also reducing dynamic loads on the chute and its mounting structure.
The updates complement the range’s existing high-capacity crop-processing system and chassis design, which includes front tyres up to 2.15m in diameter and a tyre-pressure regulation system intended to balance traction with soil protection.
