High Idle RPM vs Loaded RPM

My D14 book says "High Idle" RPM should be 1975-2075. Loaded RPM should be 1650. Does high idle mean - hand lever at max, governor doing its job maintaining 1975-2075? Does "loaded" mean lugged down from 1975-2075 to the 1650? (seems the carb butterfly would be wide open in this condition - governor trying to reach the 1975-2075. I just overhauled the tractor, would like to get benifit of full RPM's, but never overspeed the engine. This is my first tractor, this discussion board has been great. I spent mt teenage years around a small shop in Western KY. "Bud" seemed to know everything! He was a good friend and mentor - I miss him. Thanks to all the guys with experience!!

you are right. High idle is the maximum RPM the engine should run when setting still in the driveway. You adjust the carburetor linkage to get this, with the hand lever wide open. LOaded or full power means just that. If you started pulling a load the engine will start dropping back in speed from 2000 RPM. The governor will try to maintain that speed. It does this by pulling the throttle plate wide open. You can keep increasing the load till you get to about 1650 at which point you have the maximum developed horsepower. Keep increasing the pulling load and you will start to loose ground quickly.
