rear pto hyd.pump

[seedman4]

Can i use pto shaft mounted hyd.pump to operate a independent hyd. clyinder? I have the pump,oil tank and a logsplitter valve.
The reason for the quistion is that i have a mahindra 3525 that has no rear hyd.remotes.i want to add a FEL grapple...
i know i will have to buy extra hyd.hoses to run from the pump to the cylinder.....BUT CAN IT BE DONE????

To make sure we understand correctly...You have a FEL, but want to add 1 additional circuit to operate a grapple?

Yes, you can do what you said, but I think a electric diverter or a true rear remote would be a whole lot easier than what your planning...but it can sure be done your way.

I've been having a similar discussion on a different thread.

Using the electric diverter is definately easier but more expensive if you already have the pump.

The big question is the GPM of your PTO pump. You can share the hydrolics on your tractor to run the grapple and do fine but most tractor pumps are too low volume to run a hydrolic motor of any size.

It's not what you are talking about but I'm thinking about coverting my tractor to skid loader attachment. If you were running the third hydrolic from it's own pump you could run snowblowers, brush cutters, sweepers, or even a hydrolic driven bush hog off the FEL (great for pushing back the encroaching forest.

I don't want to spend the money for the pump, reservour, ect but if you already own it, it would give you alot of flexibility.

Dangerdoc,

Have you made any progress in your thoughts regarding building a pto hydro system for skidsteer style attachments?

I was talking to a rep at Erskine today about that very thing, since I want to use their hydraulic front mount snow blower rather than the long shaft pto model. I suggested that they develop a turnkey product to provide skidsteer hydo capability to tractors.

I was thinking about setting up a system on a 3 point carry-all to include the 25 gallon resevoir, pump, hoses, etc.

The idea of opening up the utility of skid steer attachments for the tractor is enticing.

I have an unused port coming off the pump. I'll be limitted to about 12 gal/min but I'm anxious to get a 4n1 going and it will be the quickest and leat expensive path to get there.

I may still a still add a pump later if I end up needing greater flow.

Yes, the OP is talking about a grapple for the FEL, which requires no more
flow that the FEL itself uses. When you say "most tractor pumps are too
low volume to run a hydrolic motor of any size", be careful. You can buy
hyd motors designed to run with flows of less than 10GPM, as used for
compact tractor implements like PHDs. It is true that many skid steers
offer higher flows, so implements designed for them may expect to have
over 10GPM available. Continuous duty hydraulic power delivery, as for
a mower, and intermittant duty (PHD) are important considerations, too.

dfkrug,

Sir,

I am looking at the Prince pto hydro pump which specs out about 21 gpm for 32hp input. This would match up good with my 5030 which produce 42 pto hp.

Do you see anything problematic in the intended setup (3 point carry-all to include the 25 gallon resevoir, pump, hoses, etc.) to obtain skid steer implement capability (of course within the confines of a 20gpm hydro flow).

You mean a Kubota L5030? It has an implement pump that delivers 9.8
GPM at somewhere betw 2000 and 2500psi. Not bad. A Bobcat 753
delivers 15.9GPM for comparison. Certainly more flow with the SS.

If that is not enough for the implements you contemplate using, then you
certainly could use that pump/res/filter system for more flow. Realize that
valve(s) you use with that pump will need to have their reliefs set (at about
2500) as the pumps usually do not have reliefs. Also, if you use the 3PH
to support your aux hyd system, what will you do to counter-weight your
heavy front implements?

Sir,

The first implement planned is an Erskine hydro snowblower requiring 11 to 25 gpm, and Erskine said 10 would not do it. I am also contemplating a hydro post hole digger, etc.

My tires are loaded with Rimguard for about 1000lbs, and the pump setup and fluid will add about another 175-200 (Hydro oil about 7.19 per gallon)

Keep tearing the idea, I need to find the issues.

RFB:

Sounds like you have been looking at the snowblower choices available.
It would be nice if there were choices that allowed the use of your
tractor's hyd system. I don't do snow myself.

Separate hyd systems ARE sometimes used when a CUT can't deliver the
needed flow. It was fairly common for backhoes on older tractors that
had a hard time putting out 5GPM when 7 or 8 was needed.

The only other thing I can think of is if you use AG tires. The fronts may be
overloaded with a heavy implement on the front and minimal counter-weight.
(Wheel weights and fluid don't help here since they do not take weight off
front tires.)
