2,000psi is likely the minimum pressure required. It would not throw snow 30’, maybe half that if it’s light and fluffy.
I (and MANY others) have also had this same idea when I first got my tractor. I thought it would be so nice to mount the blower on the FEL (even thought I could use SS brush hog on the FEL as well).
However, the more you learn about hydraulic hp vs mechanical PTO hp, and the simplicity and cost of PTO vs hydraulic, it quickly becomes apparent that there are very few situations where a hydraulic blower on a tractor is a better idea than a PTO.
For example, a 16gpm pump, at 2,000psi would provide (ideally) 18.7hp. So assuming your 27pto hp could power this blower, you are using all 27hp to power a hydraulic system that creates, at best, 18.7hp.
I say “ideally” because this doesn’t account for friction in the hoses or heat loss. So in reality it’s even less.
If I read this right, you are still planning on using the blower on the rear 3 point hitch???? If this is the case, then you should really consider selling this blower, and buying a PTO blower, you could probably sell/buy with no loss, maybe even make some money!
A PTO powered rear blower is cheap, simple, and considerably more power. You could throw snow WAY farther, and also not clog the chute as easy!!!
