is the peterson an adj one or fixed? if it is an adj did you not like it? i am an need of a chaffer for a 1688 and do not no what route to go either, an air jet, adj peterson, or the plastic long finger? i also run corn and beans, but sometimes the corn is high moisture.
Sold some of the Plastic chaffers from Gateway out of SI Distrubuting and are working very good, easy to adjust, lighter and can be repaired if need be. Made by HCC that makes the OEM's seem like good units.
