PTO Driven Hydraulic Pump

Foolster · Sep 30, 2020

I have an Allis B which I am restoring and I need it to power a wood splitter. Does anyone know of a PTO driven pump with a feed through PTO shaft? So I can power hydraulics with the PTO but still use the PTO to power something. Then if I need hydraulics I put the pump on. If not I take the pump off.

The splitter needs a 14-16 gallon per minute pump. So I can power the pump off of the front of the engine or the PTO. However I want to be able to turn the pump on or off so it is not a drag on engine power when I do not need hydraulics.

One thought I had was to mount a PTO pump to the splitter but then I do not have hydraulics when I am not connected to the splitter.

I am also rebuilding a MF65 and a Yanmar 2000. Both of which do not have good remote hydraulics so whatever I do to the Allis B I would make two more copies and install on both the MF65 and the Yanmar 2000.

Go with a front mount pump,it doesn't really put drag on the engine,and you can still use the pto.

Prince Hydraulics has made pumps with a pass through splines on it. Northern Tool Co. did have it in their
catalogs.

You can go with a 'Farmhand' type pump and an extension shaft. I have one on an M. However,they are heavy. They also put the pto hook up point about one foot
further back.Not really recomended for pto work.As said,a front engine mount would be better.Either belt drive it or run a shaft out through the crank
hole,driven right from the crankshaft.Then you also have to mount a reservoir on the tractor.Another way is to mount the splitter on a 'trailer' or a skid and
run a simple telescoping pto shaft from the splitter to the tractor.Then it's as easy as hooking up any other pto driven implement.This would be my choice.You
could also use other tractors on the splitter. Just be sure to adequetely shield it to prevent someone from getting accidently caught in it.

When I built my log splitter I salvaged a pump and control valve from a scrapped forklift. The pump mounted on the engine and was belt driven ( 2 A
belts) just like a generator.It was ideal to supply volume and pressure for the splitter with an 8 hp lawn mower engine for 40 years.

The MF65 should already have the mount on the front for a pump. You just need the pump, shaft, and adapter for it. We had a 65 with a loader and a front pump but was too young to remember much of it. My 85 has a mount as does my 175

You want to be able to use the pump for other hydraulics on your tractor so whether engine driven or PTO driven you will need to add a reservoir on your tractor, for your pump. Rule of thumb is 1 gallon of oil for every GPM the pump is rated for. So you need to plan where you are going to mount a 20 gallon tank and the plumbing for a 14 - 16 GPM pump. If the pump was just for the splitter and stayed with the splitter the reservoir tank could be on the splitter.

I think I would try to run the pump off the belt pulley. You would then not be compromising your PTO at all. But your PTO would have to be on to run the pump.

A 16 GPM pump might be pushing the horsepower limits of the B but if it does have enough oomph it will make a handy little splitter tractor. I would be inclined to put the pump and reservoir on the splitter. That way any tractor can power it equally.
