CLAAS Enhances JAGUAR 1000 Forage Harvesters to Improve Efficiency and Reduce Operating Costs
CLAAS is introducing a series of technological upgrades for its JAGUAR 1000 forage harvester range for 2027, focusing on reducing harvesting costs, improving machine efficiency and delivering more precise crop and nutrient management.
The latest developments include expanded availability of CEMOS AUTO KNIFE CONDITION, real-time yield mapping, enhanced NUTRIMETER analysis and active ejection chute stabilisation. CLAAS is also moving two high-capacity headers into full series production: the 16-row ORBIS 12000 maize header and the DIRECT DISC 8400 direct-cut header.
Together, these developments are designed to optimise harvesting performance, reduce unnecessary energy consumption and provide operators with more accurate operational and agronomic data.
Automated Knife Monitoring Optimises Cutting Performance
Maintaining sharp knives and precise cutting geometry is essential for efficient forage harvesting. Dull or unevenly worn blades increase the power required by the chopping cylinder, resulting in higher fuel consumption, additional mechanical stress and potentially poorer crop processing quality.
To address this challenge, CLAAS is extending its CEMOS AUTO KNIFE CONDITION system from the JAGUAR 900 to the JAGUAR 1000 series for 2027.
The system uses two reluctance sensors positioned above the chopping cylinder, outside the crop flow, to measure blade geometry and wear across the entire working width. Operators can set their preferred sharpness profile and sharpening intervals through the in-cab CEBIS terminal.
Instead of relying on fixed sharpening schedules, the system automatically determines when sharpening is required based on actual knife wear. This allows it to respond to changing harvesting conditions, including variations in soil contamination and crop abrasiveness.
By maintaining consistent cutting performance, the technology helps reduce energy losses, limit unnecessary sharpening and support more efficient machine operation. Knife wear information is also recorded in CLAAS connect, providing useful data for fleet management and maintenance documentation.
Real-Time Yield Mapping Improves Harvesting Decisions
CLAAS is also expanding the precision farming capabilities of the JAGUAR 1000 with live yield mapping through the GPS PILOT CEMIS 1200 terminal.
The system enables operators to monitor four key harvesting parameters:
Fresh weight yield per unit area.
Crop moisture content.
Dry matter yield per unit area.
Dry matter percentage.
Up to three parameters can be displayed simultaneously as live spatial maps in the cab. The information can also be transmitted through a cellular connection to mobile devices using CLAAS connect.
Automatic data synchronisation within active job files supports more accurate harvesting records and simplifies the transfer of information to external farm management systems through TASKDATA-compatible exports.
This provides farmers and contractors with greater visibility of field performance, helping support future crop planning, operational decisions and resource management.
NUTRIMETER Expands Organic Nutrient Analysis
The second-generation NUTRIMETER is gaining additional functionality, extending its role beyond dry matter and crop constituent analysis to include nutrient measurement during organic fertiliser application.
The mobile ISOBUS near-infrared (NIR) sensor can measure total nitrogen, ammonium nitrogen, potassium, phosphorus and sulphur concentrations in liquid manure and fermentation digestate.
The technology is compatible with slurry application equipment from manufacturers including Garant-Kotte, Samson, Kaweko, Fliegl, Wienhoff and Zunhammer.
Measurement results are displayed on the machine terminal, tractor ISOBUS interface and remote office terminals. This allows agricultural contractors and farm operators to document nutrient applications more accurately, support nutrient management planning and generate detailed records for regulatory compliance and billing.
By providing real-time nutrient information during application, NUTRIMETER helps improve transparency and precision in organic fertiliser management.
Active Chute Stabilisation Supports Accurate Crop Transfer
Maintaining a consistent crop flow into transport trailers can be challenging when harvesting at high forward speeds or operating across uneven terrain.
To improve material placement, the JAGUAR 1000 features active vibration damping on the ejection chute as standard equipment.
The system uses inputs from a chute angle sensor, gyroscope and hydraulic pressure sensor to monitor movement and vibration. An electronic control algorithm then adjusts hydraulic counter-pressure to compensate for vertical acceleration and structural movement.
This helps keep the discharged crop stream accurately positioned within transport vehicles during overhead loading and cross-row harvesting.
The technology also supports the performance of CLAAS AUTO FILL, the automated trailer-filling system, while reducing the need for constant manual chute corrections and helping ease operator workload.
ORBIS 12000 and DIRECT DISC 8400 Enter Series Production
Alongside the JAGUAR 1000 technology upgrades, CLAAS has commenced full series production of two high-capacity headers following their pre-production deployment during the 2026 harvesting season.
The ORBIS 12000 maize header features a 12-metre working width and accommodates 16 rows at 75 cm spacing. It is designed to match the output capacity of JAGUAR 1000 machines in the 850 to 1,110 PS power range.
Independent drives for the cutter discs, conveyor discs and feed drums help maintain consistent crop acceleration and feeding.
The header also incorporates CEMOS AUTO HEADER, which automatically adjusts feed disc speeds according to chop length and harvesting throughput. Meanwhile, AUTO CONTOUR uses three ground-contour sensors and two active stabiliser wheels to maintain the required cutting height across uneven terrain.
For road transport, the header folds through a symmetrical mechanism, maintaining an external transport width of less than 3.30 metres.
The second new header, the DIRECT DISC 8400, offers an 8.41-metre working width for whole-crop silage harvesting of crops up to 4.50 metres high.
It features two 4.20-metre MAX CUT cutter bars operating at a disc speed of 3,200 rpm. Individual SAFETY LINK overload protection modules help protect the cutting system against mechanical damage.
A hydraulically adjustable roller press controls crop entry into the 800 mm feed roller assembly, supporting a consistent material flow into the pre-compression unit.
Technology Focused on Harvesting Productivity
With the latest JAGUAR 1000 upgrades, CLAAS is placing greater emphasis on automation, precision data management and operational efficiency.
From automated knife monitoring and real-time yield mapping to advanced nutrient analysis and stabilised crop discharge, the developments are aimed at helping agricultural contractors and farmers improve productivity while managing operating costs.
The introduction of the ORBIS 12000 and DIRECT DISC 8400 into series production further strengthens the harvesting capabilities of the JAGUAR 1000 platform, offering high-capacity solutions for different crop harvesting requirements.
