CLAAS of America Introduces MAX CUT Mower Bar with Unique Wave Design

CLASS WaveAs fields begin to green up, CLAAS of America wants farmers to think about adding DISCO mowers with the all-new MAX CUT mower bar to their forage harvesting lineup. Introduced last fall, the MAX CUT mower bar features a wave-shaped bed, which is stamped – not welded – from a single piece of steel. This design allows for features on the bar that lead to a better cut in the field.

“This is the secret of MAX CUT,” said CLAAS of America Product Coordinator Matt Jaynes. “The wave design gives the bar the required underlying strength and allows the satellite gears to move forward for greater overlap and to eliminate the chance of discs colliding. I really feel that the wave design is the only way to meet all the requirements of a mower bar today.”

The large cross-section created by the mower bar’s exclusive “wave” design, along with the very small module openings in the bar cover, ensure outstanding strength and stamina for years of worry-free use. MAX CUT is now standard equipment on all PROFIL front mowers, center pivot mowers and hydraulic 3-point mowers.

Only the wave design can provide the space needed for two distinctive connecting pieces, which are expressly hardened for this design. The connection piece with a raised section where the knives run toward each other operates like a shear bar, preventing clumps of dirt from forming. It also protects the bar from cutting damage. With the slim line connecting piece on the right, as the knives move apart, they clear the bar earlier and start cutting immediately. The special design also ensures optimum crop flow.

“Overlap is the key to a perfect cut,” Jaynes continued. “And, thanks to the specially shaped connecting pieces at the point where the knife pairs are moving apart, there is maximum overlap between the circles of rotation of the knives, boosting the cut surface area.”

The base and cover are machined together, resulting in an ultra-precise fit between the two halves of the structure. The innovative bolt design also provides a perfect positive connection for maximum deflection and impact resistance without the weakening effect of welding processes.

Those familiar with the CLAAS SAFETY LINK safety module will be happy to see that is has been improved and is larger than before. The sealed double-groove ball bearing ensures maximum service life. Each individual mowing disc is protected by a predetermined breaking point in the safety module and will be kept away from the drive train in the event of a collision. An axial bolt holds the mowing disc firmly in position.

“We’re excited about what this new mower bar has to offer,” Jaynes said. “The new design and shorter disc allow our farmers to get the smoothest operation, cleanest cut, greatest wear and easiest maintenance of any mower bar on the market.”
