tmrand - 11/2/2026 17:00 He never said there was any difference. The only question has been if it takes more horsepower to run material through the rotor fast or slow. He asked the original poster if he had forgot to slow his rotor down when switching from beans to corn.........and stated that it would rob horsepower from the engine keeping the rotor spinning too fast in the corn.
He only asked if it had been shifted to low. Not whether it had been slowed down or not.
And I can assure you it does not take more power to run the rotor faster if the amount of material (work) entering the rotor remains constant. I ran an underpowered 1640 for nearly 20 years. Faster rotor takes less power because there is less material in the rotor at any given moment.
