tom i just took out the 1000 pto and put in the 540 shaft.
Mechanic: TomcM28, Owner replied 1 year ago

Unless you change the inside gear the PTO RPM will not change. All you are doing is changing the spline pattern so you can connect a 1000 RPM implement. You can however back off on your engine RPM to get closer to the 540 range. This typically works only if your tractor can power the implement at a lower engine RPM.

I hope this information helps you, please reply here with any further questions. Thank you for choosing Just Answer!
