Quality, reliability and ride comfort.

Invented, tested and refined. The LINER four-rotor swather.
 

The LINER four-rotor rake stands for absolute reliability in tough conditions. As the main supporting element, the trapezoidal frame profile, ensures outstanding strength and performance in all three series (LINER 4900 / 4800 / 4700). With increased force absorption potential and a robust arm connection, the machine remains reliable even during intensive use and under high loads. On the testbed it clocked up more than 61766 acres (25,000 hectares) without sustaining any damage. These results impressively demonstrate the robustness of the LINER four-rotor rake and make it the first choice for professionals who expect uncompromising reliability.

The LINER features a host of impressive practical details. All hydraulic components and cable harnesses are routed inside the main frame for optimal protection from external influences. A generous service opening provides easy access for maintenance work and significantly reduces downtimes. The trapezoidal profile keeps the machine largely free from dirt deposits and guarantees high operational reliability.

The LINER stands for outstanding and reliable raking. The clever positioning of the main frame and its compact design ensure optimum results on tight turns of up to 90°, in just one pass. The machine guarantees rapid, stable and precise turning maneuvers of up to 180° at the headland, ensuring a continuous workflow even under challenging conditions. Furthermore, with a transport height of under 13.1 ft (4 m) – regardless of the model or tires – the LINER four-rotor swather offers optimum operational safety and effortless road transport: a dependable partner, whatever the situation.

Precise, uniform swathing is what sets the LINER apart: all four rotors work at exactly the same speed and transfer the crop smoothly from one rotor to the next. With the trademark CLAAS 18-to-12 mowing strategy, the result is absolute perfection: mow with a working width of 59 ft (18 m), then consolidate the crop to a 39 ft (12 m) swath – by folding the belt/auger units up or down. Efficiency increases significantly when this swath grouping (59 ft to 39 ft (18 m to 12 m)) is combined with the LINER 4700. With the DISCO 1100 DS, up to 68 ft 10 in (21 m) can be mown for the LINER four-rotor rakes. With 56 tine arms and a generous rotor overlap, the LINER 4900 delivers perfect CLAAS swathing quality even with the maximum working width and guarantees more hectares in less time.

The powerful and robustly designed fully floating rotor suspension, together with the perfectly positioned chassis, provides unmatched freedom of movement. This allows the rotors to operate with precision even at high speeds and adapt three-dimensionally to every ground contour. The result: maximum efficiency without compromise – no downtimes, no soiling. Even on uneven ground, the sward is protected and the grass stays clean.

CLAAS GRASS CARE ensures optimum efficiency, maximum power and exceptional quality.

• Top swath quality and clean forage
• Six-wheel version for higher sward protection and even less soiling – especially on very soft ground
• Efficiency, reliability and long-term value retention
• More than 30 years' development expertise – four-rotor swathers 'Made in Bad Saulgau'
• Customer requests from thousands of machines incorporated directly into the LINER series

The LINER drive technology ensures outstanding forage harvesting quality: its highly efficient linear design, with few intermediate gears, transfers up to 50% more power to the tines – a clear advantage over hydraulic systems. High-quality friction clutches reliably protect each rotor against overload, ensuring consistent results every time. Even with large forage volumes or on difficult terrain, the LINER guarantees a streamlined workflow, allowing the tractor to continue uninterrupted. The drive also runs extremely quietly, a further plus point that enhances operator comfort and ensures a long service life.

The dual spring reliably steadies the rotors even at high raking speeds and also provides stability when turning at the headland. It is the core component of the LINER four-rotor rake – a mark of quality that makes all the difference to the swath (windrow). Added to this is the precise ground-contour following: front guide wheels carry only 20% of the weight and guide the tines precisely without digging in. This produces a tidy swath every time, which means top-quality forage. Just 1% less soiling in the forage increases the milk yield by around 31.2 lbs. per acre (35 kg per hectare) and cut. Together with outstanding maneuverability, contour accuracy and soil protection, the LINER four-rotor rake sets new standards in quality which go far beyond the technical standard.

The new chassis concept ensures outstanding results in all conditions:

• Full maneuverability: All wheels can be steered, effectively preventing tire marks on bends – for clean and gentle swathing.
• Precise adjustment: The transverse tilt of the rotor – key to the perfect swath – can be adjusted with ease and precision to ensure consistently high forage quality.
• Efficient performance: Even more accurate ground-contour following enables higher working speeds without loss of precision or quality.

More choice, more options. The LINER four-rotor rake benefits from the most comprehensive and best range of tires in its class. CLAAS offers the ideal solution for every condition – from maximum soil protection to ultra-smooth running and stability.

The LINER models are available in the BUSINESS and BUSINESS PRO variants.
The BUSINESS models include all the comfort and performance features, such as the latest load-sensing hydraulics, individual control of rotors and arms, and storable swath width settings – all operated from the comfort of the cab.

While rake height adjustment is mechanical in the BUSINESS models, BUSINESS PRO models have the added convenience of hydraulic adjustment. Perfect for maximizing efficiency in the professional segment.
