The only reason I could think of is that a machine with a jap engine won't have much torque at half throttle, so running it faster gets it above it's torque peak, thus giving it some reserve. Most of the british engines like the Ford or Perkins have decent torque down to quite low speeds, so it's not as much of a factor to them. AS far as the hydro is concerned, I'd say if you have the travel speed control you need at a lower engine speed, I can't see what difference it would make to run it faster. Since it's really all about the volume of oil being pumped, the hydro can do that with long slow strokes on a low speed engine or short fast strokes at a higher speed... Really, lower speeds should produce less wear on the pump bearings and rotating parts since they're turning slower. That's how I see it anyway.
