Engines make the most horse power when they are turning as fast as they can fill their cylinders. This means that (in most cases, faster RPM will provide more HP up to the point where the valve train, and intake system (including manifolds, carb, and ports) are drawing a partial vacuum) As the engine is pulled down in speed by load, it approaches a different plateau, the torque peak. Torque is what keeps pulling even at lower engine speeds, and it is where the cylinder filling, and combustion efficiency and the mechanics of the connecting rod geometry provide the greatest force on the crank. Ballancing the power such that the tires slip least at the speeds being pulled, the type of sled, and other factors, make the issue one of practice. Setting the RPM and leaving it there is usually like a snap shot film camera, if it isn't sunny, it is a bad exposure. Play with it. Tractors with 5000hp are different than those with less than 100.
