Sorry Ron, but you're mistaken. A rotating mass, such as a flywheel, stores energy. It does not consume energy. So it takes power to accelerate the wheel weights to speed, but no further power is consumed once the tractor is at operating speed. The energy stored in the rotating weights is recovered when the tractor is deccelerated, either by friction in the drivetrain, brakes or the implement in use.

You can verify this with any physics textbook, or prove it yourself with a rotating mass such as bicycle wheel. Spin the wheel up to speed. Does it stop spinning when you quit applying power? No, although it will eventually slow down because of friction in the bearings. Now stop it by holding your hand against the tire. Did your hand get hot? That's because the energy stored in the spinning wheel was converted to heat.
