To you 8560 owners

how "smokey" is your 8560? My 8560 always has some visible white smoke coming from the exhaust while at idle or low RPM. At higher RPM it runs cleaner so that you don't actually see any smoke coming from the machine. It only has 22 hrs, doesn't burn any oil and runs fine. The Throttle position sensor is bad and the warning light light blinks the pattern reflecting this. I was told I could run it until the 50hr service with out concern and then have the sensor changed. I'm wondering if other 8560's run this smokey or is this due to the throttle position sensor and I shouldn't see any smoke.

It very well could be your TPS making your tractor run rich at low RPMs.:2cents:

I know on a big truck (18 wheeler) you can get white looking smoke almost like when the turbo goes out and the motor is starving for fuel. So very well could be your TPS.

The TPS on my 5530 went bad, dealer said it was a common problem.

My want to check timing of fuel pump. I had an issue with stuttering and white smoke around 12-1500 rpms, realigned the fuel pump marks and problem solved.

Be sure when you start your tractor the throttle is at the lowest possible setting b/c that can make it throw a TPS code.(This will probably not help w/ the smoking but if you don't know it may help w/ the TPS issue)
Also had issue w/ a bit of sputtering and smoke on my 5530 and a little advancement on the timing fixed it.

Good luck
