    I have a 2006 Toro T-Bar with the Kawasaki 15hp. Can anyone point me in the right direction as to how to adjust the rpm levels?

    I think the throttle linkage plate has two nuts that you loosen and then slide the plate slightly to adjust the throttle up or down. This tightens the tension of the spring. I hope this helps.

    Yes, that is how I recently increased my 12.5's rpms(exmark metro).

    Just a careful when adjusting your RPM's. I thought I could take care of this on a 23 HP Kohler. I adjusted the RPM's too high and it actually made the mower worse. I took it to my dealer and he put a tach on it and found that it was running at 300-400 RPM's too high. He backed it down to where it was supposed to be and I have not had a problem with it cutting since.

    Right, use a tach and stay within specs. I increased my r's because it came set below specs by a few hundred. I set it 50 below recommended max..
