Combines Burning STS s

We got away from our JD combines because we felt that the company didn't care much for their customers, especially if they don't buy new every year. Yes, I have heard from friends about the 02 model problems, that is mainly related to the new electronic engine. They run hoter than before returning the fuel to the tank hoter. Our friend had more than one trying to light up. Him and other people have reported about power problems being related to lack of fuel pressure, too. I don't know how much JD is taking care of these problems and if they are even able to. We have an 8320 tractor with that same engine in. One day JD sent us a new fuel filter because the old one must have had a problem. One time I heard this tractor running on five cylinders. When we ran it again after a few hours, it was ok. Yes JD seems to have more problems lately. But EPA is not making it easier on all of them. All those new "low emission" engines use more fuel than their ancestors. Would somebody please explain to me how burning MORE fuel leads to lESS exhaust_emissionIJ I think all these EPA guys need a class in basic math.

I TOTAllY agree, the 2002's do use more fuel. About mid-season, John Deere called me to tell me that they had to reprogram the Engine Control Module. When asked why, they said that some of the combines had power problems and there had to be a change plus blah blah blah.. As I had no problems with the combine up to this point, I told them to skip me and go on to someone else (lol)..Well, anyway, they found the combine and reprogrammed. The end result, the combine used 25-35 gallons of fuel more a day. I actually believe that they raised the RPM needed for a different torque curve and when shelling corn, the fuel usage was tremendous!!!! But, I wonder, what DOES using MORE fuel have to do with the EPAIJ

The main reason for everybody developing new engines are the new 2002 emission regulations put up by the EPA. The engines have to burn the fuel in a little different way to meet those emission limits. The drawback is, that most of the engines use a lot more fuel to accomplish this while having less torque and less response to the gas pedal. This is going on for more than ten years now in Europe. The environmentalists screw with them emission limits from time to time just to make it worse for the engine manufacturers and us who have to run them. Unfortunately these people don't have any common sense to recognize how much trouble they cause for the rest of us. And they're not doing the environment any good either by exploiding our oil resources faster and blowing more CO2 in the air what they than blame for the global warming again.
