Auxiliary hydraulic pump

Jnip87 · #1 08-13-2018, 03:23 PM

So I have been wondering if anyone has ever attempted to run an auxiliary hydraulic pump off the back side of a non ported pump on a hydrostatic drive? For example I have a 1250, I would love to add hydraulics to it, but am not sure if I can just add the parts off a 1450 or 1650, I know I have a non ported pump, so I was thinking of where to add an auxiliary pump and I remembered that the shaft spins out the back of mine now and thought hey I wonder... Just thinking out loud here, it's probably a terrible idea or not at all doable but figured it wouldn't hurt to ask.

Been done many times. A few threads are here by members that did just that.

But IIRC, any ported pump can be used to replace the non-ported pump also.

I would just put a ported pump on it. Easier and probably much cheaper. You can usually grab a ported pump for $125- $150.

Awesome, thanks guys, I'd like to see those builds just to see if my mind was working like those who did it before, but if I can get a ported pump that cheap then yeah I'll go that route, less Fab, and I will have actual prints to follow too. Thanks again, I guess I'll try to refine my search again and see if I can find those builds.

I guess this all depends on what you want to run with the hydraulics.
On on hand if you add a pump you will need a tank, plumbing, etc etc.
On the other hand, A ported pump will allow a lot of different attachments to work.

Can you run a loader off a ported pump?
Jon will have the best answer for that.

I do not know what pressure or volume can be achieved from the ported pumps offhand or if there is enough oil in reservoir to handle something like a loader. Also, Now I am basing this on a loader which probably has the highest demand of any attachment but, if you did that and you tried to use both hydro circuit and loader at same time. Would it keep up?

What do you think Jon?? or anyone else who has done this with either?

I'm not trying to run a FEL, I want to put a cat 0 3 point on the rear, and use a deck lift cylinder to operate it, I also want to add one extra cylinder as the top mount of the 3 point to have a dump/tilt option. I have found that you can get a 3point to a skid steer adapter which would be my ultimate goal, so I can have a wider variety of attachments. So the demand for hydraulic oil would not be substantial. Maybe one day I'll make a pull behind finish mower out of the belly mower, an auxiliary pump would be better suited if I made it powered by a hydraulic motor, but this is all theoretical now.

You can direct drive the pump off the rear of the hydro but you will have to relocate the battery. Check out sawdustdads tandem cub thread where he ended up doing this. Other guys that have done it previous have been successful on 1x7 series that have the same type of rear fender set up but battery resides under the hood. I said in dad’s thread that I believe tim Crutcher did this on an earlier gear drive nf but haven’t looked it up. I would vote for putting in the ported hydro.

Thanks guys for all the input,this is a winter project idea, so nothing happening soon, maybe I'll start the process of locating parts to get ready, the ported pump is definitely the most appealing idea, those builds were awesome tho, glad to know I wasn't the only one who had this idea and that I'm not crazy for it either.
