That's a decent ballpark figure to start with. As soon as you engage the PTO your hour meter will be replace by a PTO RPM read-out, so you can fine-tune your throttle setting as needed.

i was told i could go 2600 that sounds high to me

Like 3BPercherons says, your indicator should tell you the actual PTO speed. Mine is right at 2250 engine for the 540. I have heard of people running their higher than the 540, but I don't.

I run at 2200 rpm, 500 rpm on the pto.

2250 is my start point as well, but I end up fine tuning by feathering the throttle pedal to stay in the ballpark of 540 as I climb and descend hills and move through grass and weeds of varying thickness.

I would, but I'd have to wear my glasses to do that

When I had that model tractor and was running a 15' cutter with it I ran the pto speed at 600 rpms. Sure seemed to be a lot easier on the whole rig. Mower cut nicer to.

Hello; Do you have a Kubota M7040? I've got a 2008 M7040 with 150 hours which is experiencing a "clunking noise" during idling. Dealer says Kubota can't find the reason why it's making the noise. All systems are running fine otherwise. Have you heard of this issue? Thanks; Nicot, Upstate PA.

When my PTO lever goes "on", the PTO RPM indicator becomes my tachometer. The engine RPM is nice to know, but I ignore it and use my PTO RPM display as my reference.

If you have a PTO RPM indicator, I suggest you use that and not worry about the engine tachometer.

In my eyes, the only time you should worry about the engine tach and trying to get a specific RPM is when you do not have a PTO tach and need to use the engine tach to get the correct PTO speed.

Unless using implements that require a different PTO speed, get the PTO RPM to 540 (or as close to that as you can) and hold that engine RPM. Change gears accordingly to get the ground speed of your choice.

Also, as a rule of thumb, engage and disengage the PTO at idle. (I make this statement so all of this engine RPM talk is not confused with engaging and disengaging the PTO.)
