Yep, you're right R72 and R.O.M., after re-reading my post, I agree that I was perhaps short and harsh. NC Gleaner, I apologize to you for sounding that way. Your title seemed to belittle the Cats (which are still my favorite combines to run). Afterall, they (Cat and Claas) have also brought some new levels of performance and features to harvesting over the past seven years. But, so have the other brands. like many other people, I also use this web sight to gather good and factual information, as well as listening to others personal experiences. This is especially helpful during the slower winter months. I think we would all expect an R70 (Class 7) to out perform a (Class 5) Cat 450 _w 30' header. The R70 should also be able to compete against a Cat 460 (Class 6 machine). If his R70 is well maintained and adjusted, it should theoretically be about an even be a match for a 470 with the same size head. Although NC Gleaner did not provide information on year, models or header sizes, I doubt if the R70 was running circles (what's this really equate toIJ) around a 480. The R-series Gleaners have always been known to be pretty fast and productive in corn and wheat, The natural flow design is perhaps the best way to feed a rotary, but the offset feederhouse and header is a bit of a pain. Some day, if they survive, the cage area to the left of feederhouse will probably be turning top forward to create a Bi-Rotor configuration and even more productivity adnd dynamic vane angles. It's a "natural" configuration for this, with its existing 360 degree concave _ cage. One of you should at least modify one as such. The Machinerylink fleet included JD, Cat and CIH combines the past two or three years.
