Cleaning System

Final crop cleaning and returns separation is done by the cleaning system. As crop falls from the grain pan, it cascades to the chaffer via a cascade chaffer pan. The reciprocating motion of the chaffer and air from the cleaning fan, float the residue rearward and accomplishes initial cleaning of the crop.

The Max Flow cleaning fan, chaffer, and lower sieve make up a closed pressurized shoe assembly.  A large volume of air provides screening and pneumatic cleaning. The Massey Ferguson 9690 includes a 6768 in² (4.36 m²) cleaning area and the 9790 & 9895 include 8296 in² (5.35 m²) cleaning area.
