Chaffer/Sieve area plugged

While installing the PFP enclosed discharge beater we noticed that
the front end of both the chaffer and sieve were plugged with straw
and chaff, I'd never seen this happen before.


I looked at used S series machines on a dealers lot and some of them
had the same condition.


Anyone else notice this and if so how do I avoid it.


Thanks,


MS
