Adding hydraulic capacity?

I?m planning on getting an air seeder to pull with a Case 2470 open center tractor. While there are a few seeders around with small engines, I've never seen one close up. Most seeders have a hydraulic fan needing 8 ? 10 gpm flow, and I?d like to get a hydraulic fan, then upgrade to a closed center tractor as soon as I can. The 2470 has 1000 PTO.
I?m looking at either building a PTO powered hydraulic set up?.pump, tank etc, or I can put a small engine on the tow behind air cart, either with a hydraulic pack on it or maybe even direct drive the fan with a v belt. Fan needs to maintain 2800 ? 4000 rpm. I?m also looking at pull type sprayers, so it would be good if I could also use the same thing to drive a hydraulic sprayer pump on open center tractors.
Any one have any experience with building a PTO or small engine hydraulic power pack for constant load?
Thanks,
Chris
 
The important component is the anchoring of the pump using an arm and a link to a fixed point on the rear of the tractor to prevent it from rotating with torque. A pump like the one in the link will work, and be reasonable in expense and difficulty. If the fan on the planter is self regulating, no ossue. if volume regulation is needed, throttling the tractor, or using a flow regulator at the planter is needed. A 3 gallon reservoir would provide cooling and volume. if the reservoir is at or above the pump, it will self prime. Jim
One example
 
Hi Chris, had a neighbour with a morris air seeder that used a PTO powered fan... Iirc it was a prince PTO pump with a reservoir mounted on the hitch of the air seeder, I think he had a flow controller to set fan speed, which he had to do manually...

Peavy mart might have or Princess Auto. If you need to talk to someone the hydraulic guy at Princess Auto head office in Winnipeg was good when I added a engine drive pump for my old loader tractor. Can't remember his name though...
 
The ones I have seen that don't use tractor hydraulics have an oil cooler on them. You won't keep it cool otherwise. My planter and sprayer just use the tractor. The 7800 had a switch you turn to run the hydraulic motor vs regular cylinders.
 
Yeah, I think I'll need at least a 10 gal tank, maybe 15. I could also rig up a cooler in the line near the fan. Thanks.
 
Hi Oli, hows it going? Do you still have the Dom 106 combine? I had a bit of a change around and now running this 2470 dinasaur. I guess its cheap hp if it?ll hold together?. miss the Magnum though! I?ve seen the Prince PTO pumps in the PA catalogue. Did it hold up to constant use ok for your neighbor? I?ll call in to the local PA store, or call the Winnipeg office, and see what I can find out. Thanks
 
Some air seeders have an oil cooler in the intake airstream to the fan.

If the air seeder he is going to pull is set up that way, it will be a big help.

If not, it would be easy enough to install one, after looking at models so equipped.

Lots of older Versatiles have been set up with added flow hydraulic kits from Atom-Jet of in Brandon, MB. I've attached a link, you may want to peruse their information to get ideas for your Case.

A wet line kit off an old DOT snowplow truck works ok. They often seem to have closed centre so they can adjust bed chain speed and still run the spinner full speed all while using plow and wing controls.
 
If it helps with your planning at all I have an air seeder fan hydraulic driven sitting in the shop from a flexicoil aircart that only had one season of use.
Could give you a great deal on it.
 

Why not plumb the new pump to draw from the tractor's hydraulic oil reservoir , return the oil to the tractor's reservour and use cooler on the tractor ?
 
Ok, do you mean to use a PTO pump, but pull unpressurized oil from the tractor, then dump it back in. I've got to fit in a case drain line as well.
 
(quoted from post at 15:46:40 11/27/15) Interesting. Do you mean you have the fan unit, or something to drive it with? Where are you located?

What I have is the fan unit with the hydraulic motor on it
You will still need a hydraulic supply to run it.
From reading your original post I was under the impression you were still acquiring equipment/parts to build a system.
Located NE of North Battleford.
 
Yeah, still got the old girl...

On the pump front, as far as I know it worked well... Machine got sold a couple of years ago when he quit farming, not sure where it went... If I was you I'd get as big a reservoir as I could for the job, and if you could oversize the return lines in steel pipe not rubber hose the that would help keep the oil cool... Your other option for a pjmp might be one from a haybine...
 
Would a PTO pump and oil tank off an old 12 row cyclo corn planter work? They also had oil coolers on the fan inlets.
 
Good to hear it's still running. I hadn't thought of a haybine pump. Thanks for that. That's another option I'll look at.
 
If your going to spend all that effort on that old tractor why not sell it and look for a 90 series. Should be available fairly cheap and I believe it can run an air drill with no modifications other than a case drain which should be fairly easy to set up. (I have seen a stock 2390 run an airdrill fan). The overall money spent cant be that much more than what you are proposing.
 
Chris I just came across an ad on Kijiji that has what I think you are looking for.
