Please!!!! I've seen an R-72 kill every other combine I've seen by it ( from a 9600, 2388, 9750STS, even a 485 Cat) and it's alot more servicable than most of them. I also find it amusing that JD wanted to copy some aspects of Gleaner's machine, but couldn't due to the patents on it. Hmm... Aside from the rant, the STS's seem to perform very well, although I'd go with the case...JD is going to (and to an extent already is) experience what Gleaner did with the N series...needs for updates, little bugs, etc etc. I've heard the STS's dont drink as much fuel (due to the "3 stage" cage). If you dont have too many weedy fields, give a Gleaner a look...they dont digest the weeds as well as a Green or Red machine, but in average conditions, the silver beasts smoke anything else. Best bet would be to try to get a demo of both, and choose whichever one seems to work best for you. Happy harvesting!
