I am building a splitter on a 12 inch I beam with a 15 1/2 inch tall wedge similar to the Timberwolf design. I would like to run a 4 way or 6 way or larger slip on wedge. I currently have a 5" bore, 18 inch stroke, 2.75" rod cylinder. I was originally going to run a 22gpm 2 stage pump off of my 13hp engine but now I'm toying with the idea of running it off the tractor with a PTO pump. The thing I like about the PTO pump is the constant gpm flow vs the slow second stage on the two stage splitter. I have 46 hp PTO off my TYM 603 tractor and the tractor has a standard 540 6 spline shaft, but the tractor has a lever to switch it to 1000 RPM PTO from the cab running lower RPM on the engine and saving fuel but with less mechanical advantage. Has anyone ran a pto powered splitter with the 1000 rpm range?
I know Prince makes some pumps but they are pricey and only 2250 psi max, but now there is another brand, Dynamic, listed by surplus center for half the cost of the Prince and makes 2500 psi max. There is a 21 gpm pump in 6 spline 540 but also a 39.3 gpm pump 21 spline 1000 rpm pump (I would need adaptor or run a pto shaft). My thought is buy the bigger pump and then run tractor in the 1000 rpm pto mode just above idle and I would get at least 20gpm at idle roughly and then if I kicked up the rpm on the tractor engine I could get the full 39ish gpm?
So what am I missing? Should I do a stand alone gas unit for more psi or the tractor pto for more flow? Any other thoughts or ideas as I am having a hard time deciding, maybe I just need a bigger hydraulic cylinder?
