World's Biggest Combine Has No Straw Walkers
"It has more capacity than any other combine in the world," says Claas about its new Lexion 480. The big combine features a new-style threshing system that uses both conventional and rotary separation to harvest 1,500 bu. per hour or more.
Power is supplied by a Mercedes 375 hp diesel engine that's located behind the grain tank for quiet operation.
The threshing system includes a "pre-separation" rotor that mounts ahead of the existing combine cylinder and a spiraled "accelerating" drum behind the cylinder that aggressively feeds the crop to a pair of axial sieve drums that replace the straw walkers. Claas said it's goal in building the machine was to boost capacity yet still keep straw of baleable quality. Straw can be dropped out the back or chopped with a new-style, high capacity cross knife and shear bar that feeds chopped material in a high pressure spreader unit with dual oscillating nozzles.
Claas claims that the straw exiting the combine is of "baler quality" but if chop-ping is required, the straw can be directed into a chaff and straw chopping unit that blows the material through two swiveling funnels to spead material over a 30-ft. width. The luxury cab has a computerized control system that allows the operator to press a single button to select preprogrammed settings for fan speed, drum speed, concave gap, etc., required to harvest a particular crop.
