agflyboy, I have customers with disrupters in their combines work ok. But I sold some grates with sections last fall and all were very satisfied. Had problem with one customer, spent some time with him, found sections installed wrong. Changed position(more or less turned around, flat part of section has to be against the metal support)installed grate in center position, went and combined, went thru wet spot where only weeds grew and it just shreded straw stems were torn pretty good allowing for fall tillage and decompositon. Make sure vanes above grates are in good condition so as not to slow crop flow.
