Sorry bundybear, but I have run 6600's all the way to 9770STS and just about every model in between. That's my opinion from my experience having driven them. That's my opinion having also driven Case-IH, Massey, Gleaner, New Holland machines to compare to. With experience one tends to develop an opinion over time.
sorry redhat but i've run deeres since the mid 90's putting 2000 hours a year on them sometimes and have never had to wear earmuffs. and before you respond saying i haven't run a ih, i have and for the last two years cut a swag with my friend who has a 2388 and and a 7088. he has run my 96 and never mentioned the cab being noisy. and being red thru and thru he would find anything to niggle me over!
Your right our 8120 does spend more time in the shop then our STS used to.......
Since it can harvest 50% more per hour, it's done almost a week sooner.
We loved our STS's for the most part until we traded for our first 8010 and found out what we were missing.
I'd tell him to retire. J.K. you wanna talk about loud and annoying how bout that d**n beeper when you come to the end and raise the header on them 2388's that's annoying. The unloader is alittle bit loud but thats a good thing to hear in my opinion, cause u must have bushels out there if ya hear it often.
Seriously, you die hard green guys are diluted. My 9750 unloader is loud and I believe it to be the very same on a 60 series. I guess the cab on the machine is quiet compared to a 6600 with the engine next to the cab.
