pto pump on grain truck

Hey I'm building a log splitter and found a pto driven pump off a grain truck wondering if anyone can tell me what kind of rpm rating the pto shafts turn at I know it has to do with engine speed but what would be say low speed rpm be. I don't want to waste my time mounting this up if the rpm is to slow. I know that a 16 hp briggs that I want to run it with turns out about 3600 rpm at full throttle.

Thats correct. If it is a Williams pump it will run at 3600 for about 5 seconds and grenade, with possiblr dangerous results, Trev.

C Tucker is correct.

Think about what Trevman says.  Sure, $50 is cheaper, but how much will your hospital visit cost?

I have a couple of machines very similar to what you are talking about building.  I have never had a block of wood that would not split on one pass through a 9 way wedge or a 6 way wedge (both of these are adjustable by hydraulic ram to raise up or down depending ont he size of the block) on either of my machines.  I ran them originally with a 4 inch ram, not enough, then a 5 inch and the 9 way has a 6 inch but it will run fine with a 5 inch I am sure as I used what I had when I built it and felt a 6 was the right size.  A 28 gal/min pump on each one brings a cycle time of about 5 to 7 seconds one way, I use the same ram via a mechanical linkage to run my saw blade up and down- when the splitter is extended the saw is up, when it comes down the block falls into the open splitter and when the saw goes up the block goes through the wedge.  I have had both me wedges torn off by the 5 and 6 inch rams.  This is a 1 inch by 10 inch steel piece and the wedge pieces do need to be hardened.  pm me if you want more info.  I run both these processorw ith a 6060 tractor and can produce in good straight logs easily 45 face cord per day on about 11 gallons of diesel fuel.  I have run them with other tractors but the 6060 gives the best fuel economy.  Waiting for a two stage pump is a joke in my opinion.
