With a total area under wind-control of 6.54m2
on the CR9070, CR9080 and CR9090 models, and of 5.40m2
on the CR8070 and CR8080 models, the cleaning shoe efficiently handles the largest grain volumes. The Opti-Clean™ system optimises the stroke and throwing angles in the cleaning system. The grain pan, pre and top sieves operate independently to optimise the cascade for greater capacity, and the longer sieve stroke and steep throwing angle keep more material airborne, for even higher cleaning efficiency. The opposing motion of the grain pan and bottom sieve to the pre-sieve and the top sieve reduces overall machine vibrations and increases operator comfort.
