Re: How to Determine PTO RPM\'s ?
<font color="blue">
Can I run the engine at a "Higher" RPM and exceed the PTO RPM's of 540 without damaging my snowthrower?
I was running it at about 2800-3000 since it would throw the snow farther at the higher speed.

TimP, you've had the tractor for 7 years, and you've been running the snowblower at 2800rpm, which is something over the 540 PTO rpm all this time. I think you answered your own question.
But consider the gearing. It takes 2500 engine RPM to get the PTO to run at 540, so there is ROUGHLY a 5 to 1 gear down. Running at 3000 engine RPM is going to put the PTO RPM at roughly 600? I suspect there is enough safetly factor engineered into the gear box of the snowblower to handle that.
