I'm looking forward in going into canola and compare combines, last fall my R62 went down real bad when I was in canola. Always had a problem with the front feeder house feeding issues in green canola stems. So when the R62 was out of commisioned I rented a older R72 , the front feeder chain is out a little further then the 62 and the whole floor of the front feeder house had been pulled out from previous owner. Didn't know how that was going to work but went at it anyways. Worked like a charm ! Put a hundred hours on it without any issues at all . Ended up buying the combine as a backup. So as you can read, I,m looking forward in comparing them this fall, if that 72 outshines the 62 in feeding the canola,well, you know what i'm going to do.
