OMAHA, Neb.—Designed to maximize efficiency and speed, the Disco 8400RC Plus is impressive both in size (working width) and in the technology that makes for faster drydown. It's a welcome addition to the Claas range of products and for harvesters who work with hay.
The 27'3" triple mower allows for high-capacity harvesters to mow and condition crops like alfalfa and clover without damaging the leaves, keeping nutritional content at its peak. "What's unique about the new Disco 8400RC Plus is the new roller conditioner,” states Bob Armstrong, Claas North American product marketing manager. "Engineered with two rubber rolls in a chevron design, it crimps the crop for faster drydown, saving you time.”
Simple and unique to Claas, the bottom roll is driven and, in turn, drives the top roll through its intermeshing design—a simple power transfer concept that eliminates gearboxes and drive shafts. The rolls are spring-loaded and the gap and pressure settings are adjustable. The segmented rollers also allow for low-cost replacement—only the 12" segment of the roll needs to be replaced versus the entire roll.
Operators can also harvest faster with less wasted time in and out of the cab with the new Claas Active Float hydraulic flotation system. With one-touch operation direct from the cab, it gives operators the ability to adjust mower flotation and change header pressures for various field conditions. Because of the independently adjustable float, operators have the option of different float pressure on side hills—good news for those who work on hills, as the side shift of the mower is eliminated. The flotation system quickly adjusts and helps reduce fuel consumption, while Active Float also reduces ash content.
What's more, the disks use thick 1" gears as part of the Safety Link system, which protects from internal damage when disks come in contact with any external objects. The use of a smaller disk in the Disco 8400RC Plus allows for a more uniform cut in light crop. Using large disks, the cut usually shows difference from one end to the other. These smaller disks can be staged closer together, further enhancing cut uniformity.
