The new Claas rear-mounted Disco mower is not only the largest of its kind released by the brand but also features the award-winning Max Cut mower bed
Boasting an impressive 4.2-metre operating width, the new Claas Disco 4400 becomes the largest rear-mounted linkage side mower yet released by Claas.
Claas Harvest Centre product manager (Greenline) Blair McAlwee says the new model incorporates the award-winning Max Cut mower bed, central pivoting, floating suspension, and a compact vertical transport position.
“Max Cut has set the standard for chop quality, ultra-smooth running and fuel efficiency since its introduction in 2014,” he says.
“Its innovative design enables the large drive sprockets of the mowing discs to be placed well forward, ensuring maximum possible overlap and surface area with multiple teeth engaging at two points.”
Uniform spacing between the discs ensures a consistent cut. The wave-shaped mower bed is forged from a single piece of 5mm thick steel profile, which in conjunction with the skids creates a dirt-repellent tunnel effect. Specially hardened inserts are shaped differently to accommodate the mowing discs as they run together and apart.
“This design provides a shear bar for an effective cut and maximum overlap for optimum crop flow without clumping.”
Like all Claas Disco mowers, the PTO speed can be reduced to 850rpm to reduce fuel consumption in lighter crops without compromising cutting performance.
The permanently lubricated mower bed is fitted with the Safety Link safety module as standard.
“Each cutting disc is protected by a predetermined breaking point, isolating it from the drive train in the event of contact with a foreign body,” Blair says.
“An axial bolt holds the cutting disc firmly in place to prevent it flying off.”
Disco 4400 also incorporates the tried-and-tested Active Float adjustable suspension system and Claas’ unique hydraulic collision protection.
The Disco series spans more than 30 front-mounted, rear-mounted, and trailed models with operating widths from 2.2 to 10.7 metres, which are all fitted with the same award-winning MAXCUT mower bed.
