Yes your right about the fast throttle. Most of the work we do with the tractor requires pto operation at pto speed. I run it with the throttle against the upper stop 80% of the time. I noticed no gain in no load rpm from the time it was new tell the dealer change in rpm. It ran 2650 no load consistently from new. The dealer is trying to correct my complaints about not being able to hold pto speed under loads that should be easy for the tractor.
