540 rpm PTO implements usually have lower power requirements. Small balers, grinder/mixers, swathers, mower conditioners, etc. 1000 rpm PTO implements usually have higher power requirements, forage harvestors, combines etc. With the higher speed they can do the speed reduction and torque multiplcation within the implement. This means drivelines, U-joints etc. can be built smaller to do the same work. I worked for a JD dealership up til two years ago, and when dynoing a tractor I would always see about 3% lower HP readings at the same engine speed when running at 540 RPM as opposed to 1000 RPM. Deere says to expect the loss due to the extra gearing they use to get the further speed reduction from the rated engine RPM. If you have enough power for the job you can just but a 1000-540 spline adapter.
