I have a hydraulic loader mounted blower on my 45 HP tractor. I HAD to also install a rear mounted hydraulic power plant to support the blower. The rear hyd pump supplies 15 GPM at 3,000 psi and is independent of the tractors hydraulics.
I paid about $10,000 for my setup. Before i purchased it, i checked out some top line rear snowblowers that were in the 4,000- $5,000 range. so this was 2x the price ...or a bit more
that being said...i am SOOOO glad i bought it. My neck thanks me every time i use it. After 14 years of using an open cab and rear blower, my neck just couldnt take another season. Now with a heated cab and loader mounted blower, im in pig heaven.
After a few adjustments upon initial usage, it's working fine. Very powerful and can even throw wet snow a considerable distance. The ability to raise the blower up over 6' in the air allows me into tight corners, and allows me to clear the piles of snow that come off the barn roof.
