Anyone here using Precision Farm Parts enclosed cylinders on a 9000 series walker combine?
http://www.pfparts.com   How is it working for you?  I have been using a sunnybrook enclosed cylinder for 5 years. Can really notice fuel savings but teeth on bars are to wide and deep for good thrash in wheat. Only place to get a narrow space bar is aftermarket. Planning on pulling it out and putting in a PFP cylinder and beater with grate. Any experiences with these please reply.

TIA

Brad
