Thanks for the info, I have the splitter hooked to the ferguson tractor. It will split anything you put in it but it's slow to move the cylinder. But a good thing about that is , less chance to get fingers caught. Any way I have a 10 hp Briggs cast iron engine, or I was thinking about hooking it to my ford lgt 100. Mount pump and tank to the tractor when needed. I will start looking at pumps soon. Do splitter pumps have a top rpm range , or does it matter. ?? Noel

I don't think I'm strong enough to use your splitter for one day , by back, shoulders , heck every mussel  would ach lol . . How many GPM dose  a splitter like yours need to run at a decent pace ? Or one you would be happy with ?

Most of the two-stage pumps are designed for direct drive from a small engine, so are rated at 3600 rpm. 

 

Less rpm = less flow = slower cycles, but pressure remains the same.

 

Too much rpm causes excessive wear, and requires more hp.

16 gpm 2 stage pump mounted directly to your crank on the Briggs. The pto is too slow for them off the Ferguson. Does your LGT have a rear pto? If it does then you could use that to run the same 16 gpm pump, only thing is it would need to be a reverse or counter clockwise rotation looking at the pump.

Lgt100 has enough room at the front for a belt to come out the side. Open sided tractor. I believe the ferguson is 3 to 6 gpm, so if I had an 11 to 16 gpm, I think that would be good. The splitter stand at about 36" , counter height. Much easier on the back than been bent over at the splitter. Noel

If you're heavy into guz intas, some useful info in hydraulic design.....

1 US gal = 231 cu in
vol cylinder = .7854 x d x d x stroke length
cu in /rev x rpm / 231 = gpm
net Hyd HP = psi x gpm / 1714
total HP = net hp/efficiency

cylinder force = pressure applied x .7854 x cyl dia x cyl dia

Typical efficiency of hydraulic system including some safety factor = 75%

Or you could just use a hydraulics spread sheet from one of the sources previously mentioned.

Typical speed rating for direct drive pump 3600 rpm. PTO pump 550 rpm or 1000 rpm. Max pressures for recent model pumps should be about 3000 psi. Depending on age, some agricultural systems ran on as little as 1200 psi maximum. Other modern systems on construction equipment (like dozers and excavators) may run at 4000 psi or slightly more.

Lgt100 has enough room at the front for a belt to come out the side. Open sided tractor.

 

Most all 2-stage pumps are designed to be concentric-coupled to the engine, which eliminates side-thrust on the pump input shaft.

 

If using a belt or chain drive, extra support may be needed to prevent side-loading of the pump input shaft.

I use an old single stage pump splitter. Had it 8 or so yrs, always got the wedge stuck.

It came with a 7hp flat head Honda on it that was tired, I put a 8hp Briggs IC engine on it and it was a little better but still got stuck.

I then put a 13hp Honda clone on it, that motor didn't load up or slow down like the others but found that the wedge got stuck even more often.

I always thought it was slow and didn't have much splitting power, also the return stroke never worked right, you always had to hold the control down for the ram to move back, even though it had the kickoff feature.

So I changed the control valve with a new one that has the kick off valve on it and WOW what a difference. Now the wedge never gets stuck, it just goes through almost anything and you can stall the motor out by holding the control down at the end of it's stroke in less than 1sec.

The pressure relieve on the new control is way higher than the old one.

Now the splitter is faster even though the ram moves at the same speed for 2 reasons. 

1 -  it never gets stuck any more.

2 - the kick off feature works so you hands are free to handle the wood.

 

If it had a 2 stage pump on it, the right one for the size of motor it would be even faster.

 

Another way to speed up the operation is have 2 people work the splitter.

1  just works the control and the other handles the wood.

 

Just wanted to add the according to the instructions that came with the new kick-off valve the pressure relieve is set at about 2100psi.

If you can live with a single stage pump and want to use the Ferguson, Princess Auto sells pumps that attach to your pto shaft and are designed to run at 540rpm. They also have ones that work with the newer 1000rpm pto's. They have several different ones, with differnt prices depending on flow rate, but as an example 16.9gpm @540 rpm for $460 Canadian dollars, plus Hst and shipping of course
