Just doing some head scratchin' here and wanted some TBN community advice...

Lets say, for talking purposes, I wanted to run a hydraulically driven SSL snow blower on a large frame CUT class tractor FEL with a SSL QA adapter.

Looking around at some specific SSL snow blowers from Loftness (just for an example), a 6' standard flow model requires 17-20 GPM. Various 6' high flow high capacity SSL snow blowers list GPM ratings from 21 to 35 GPM. No CUT I know of has more than about 10-12 GPM rating for SCVs.

A quick look at Northern Tool & Equipment shows they sell a Prince 540 PTO driven hydraulic pump rated at 21 GPM. I'm guessing there are other suppliers that can provide even higher flow rate pumps.

Not knowing much of anything about hydraulic pumps and systems, my guess at what's needed for my proposed high flow system is the PTO driven pump, some kind of hydraulic fluid reservoir, some kind of hydraulic oil filter, and various plumbing, hoses, and hydraulic quick connects required to route the new high flow system from the rear of the tractor to the snow blower on the FEL.

Ignoring the cost factor for now, am I crazy for even thinking this way or does it seem doable?

ANYTHING is doable if you have money!
THE SURPLUS CENTER Has all the stuff you need. You would probably spend $1200 to $1500 to get it done, then add the price of the blower, and you'd probably be close to the price of a factory blow.

You have all the parts listed that you would need, the reservoir would need to be at least 21 gallons to macth the PTO pump-that would make good ballast though mounted in the rear...

Sounds very doable.

I would double check that the pump is rated for continous pressure duty. Also, don't forget you'll need to budget a tank (5gal?), a valve, hydraulic oil, and maybe 30 feet of 1/2" hose (with fittings/quick couplers etc).

If you want to run other attachments in the summer or more than say 20 minutes of snowblowing (pumping a motor with 20GPM @2500psi will add 100 degrees F to that oil faster than you'd imagine), I'd move to a 10 or 15 gallon tank and add a heat exchanger or two with fan.

Great project, just don't forget the hidden costs! /forums/images/graemlins/cool.gif

I added a PTO pump to my little JD 4100 (apx 18 PTO HP). It was only 10 GPM setup. I used it to power hydraulic attachments on the loader arms that were originally designed for a Toro Dingo. I thought a 5 gal resevoir would be sufficient, but using a hydraulically-driven trencher put a heavy heat load on the hydraulic system. It got hot enough to bubble the paint off the resevoir - probably a bit hotter than it should be run.

If I ever have to use the setup again, I will add an oil cooler. I thought about putting an oil cooler back near the pump, but thinking about it some more, the best place would be up near the radiator so I could avoid having to also add a fan and wiring to run the fan. The hydraulic lines are on my setup are plumbed to to a valve bolted to the side of the dash area, so its only a couple more feet of hose to run a loop up to the radiator area and back on the return side of the circuit.

bam....I posted a similar question not too long ago. I don't think it's crazy. Interested to see what comes of this post. -I've got about 12 gpm off my front hydraulic port, which I don't think will do it.

hi i suggest you to look for hydraulic piston pump they have high flow per RPM, i bought one for 10 dollars on ebay, beware of the shaft rotation they mostly CW rotation

Ideally you want 1 gallon of fluid for every gallon of flow. A 21 gpm pump needs a 21 gallon reservoir.

I have a 28gpm pump on my splitter and a 15 gallon reservoir. The reservoir gets too hot to touch and the fluid is really churning in there to the point that I can't use a vented cap like I should. Off and on, I try to figure out a way to increase the size of the reservoir, but that would mean reconfiguring the whole thing and it's too much of a pain to mess with.
