PTO RPM vs Engine RPM

[belah]

I have a 1993 Kubota M4030su 2 wheel drive with a 540 PTO. What "ENGINE RPM" do I need to run the PTO at 540?? I will be operating a 25 kW Winco PTO Generator which calls for 540 PTO RPM. Thanks Belah

I stand to be corrected,but it is my understanding that the 540 R.P.M. is the maximum PTO speed at maximum governed engine speed.

On all my machines, if I recall correctly, just a bit over 2000 RPM gives you 540 RPM. My engine RPM goes well above that and I have often run the tractor at higher RPM. For some attachments (like my backhoe, which has a PTO driven pump) I run the PTO pump well above 540.

Looks like max rpm on your tractor is 2600. Which puts the pto at 640 rpm.
540 pto rpm looks like you should run your tractor at 2200 rpm.

Thank You for all of the replies. I think that i've got it now. The engine runs at 2200 RPM to get 540 PTO RPM.

belah, That is correct. I checked my Dad's '93 M4030 SU (this past weekend) that he bought new and 540 pto rpm shows to happen at 2200 engine rpm. Good Luck!
