On my S680, I have the separator grate spacers installed for both corn and soybeans. I bought a S780 and noticed that it as separator grate spacers installed on every other grate along with disrupters. Should I install grate spacers for all the grates like my other combine, or leave them staggard? I've never had a 700 series or disrupters, so I'm sort of clueless on what to do here. Thanks!
