I would never of worked that out last time i ran a pto was on a big john deere and was all digital.

 

I see most saws run at 540, why is this 350? just geared differently?

 

It's more than likely a way of saving fuel - older tractors don't always have a 540 eco setting so it just means you can run the tractor at lower revs than 540 would be but still have the right blade speed.

I think it says in the instruction book to get 350rpm on the PTO it's usually between 1200 & 1300rpm? I run mine at 1250rpm.

Don't normally read instructions but was bothered if I ran it at too high rpm it might knacker something that wasn't designed for it.
