7720 cracking grain

Wondering if anyone could help me.

My 7720 was cracking wheat for the first time last season. Had correct drum speed, have checked cylinder bars and concave which seem to be o.k. Had to close up bottom sieve a fair bit last harvest since was getting trash in grain tank which meant that i had more returns than in previous years. Don't know if this would cause the cracking? Anyone have any ideas?

yup a tight lower screen will increase your quantity of cracked grain!!! try tightening the top screen next time or increasing wind!! also maybe try lowering the cylinder speed and u might have to tighten your concave a bit!!! i have always heard this saying concave thrashes and the cylinder smashes!!!!
Thanks for that. I'll give this a try.
