Many tractors over 65 hp will offer both. Above 150 hp they often only offer the 1000 rpm. Due to the amount of hp needed to transfer, the 540 shaft will snap off. IH got to using some very rare earth metals to make their 540 pto stubs. Some of those big grain augers (13 inch, 70-100 feet long) use direct drive 540 pto - but they also need about 120 hp. A lot of broken pto stuff on those deals.... Also some of the small compact tractors offer both 540 & 1000 rpm on their 15-30 hp tractors. Some of the small implements use the higher speeds, then they can use cheaper driveling parts. --->Paul
