Just when you think you have had a original thought.  :D (not really, I know better)

They have some nice gear, looks like they are in Austria. This one popped up on youtube so I got looking around on their channel. I posted a link here.

Is it me or does it seem over seas has much better stuff? Could it be that they are less sue crazy and don't have as much safety crap?

You make it idiot proof and they make a better idiot :)

One of the things I see over seas all the time are the MAN flat nose trucks. Makes so much more sense for more cargo capacity. Unfortunately Americans just have to supersize everything!

The MAN trucks actually have hydraulic assist front drive. supposedly there is no parasitic loss when it is disengaged. I watched a video on it before, pretty kool technology.

If you want to speed up your cycle times you can plumb your cylinder so that when you are extending both sides of the cylinder are plumbed together and both get pressure.  The side without the rod has more square inches pushing on it so it will overpower the side and cause the cylinder to extend.   As it extends the fluid on the rod side has no place to go and is forced into the non rod side.  The rod will extend very fast but have very little power.

Then once the wedge hits the wood you only put pressure on the non rod side and it will have power when extending again.

I don't know if the extra complexity and the need for an extra valve is justifiable for the extra speed.

Those splitters are pretty sweet although the splits are pretty long.

I've convinced myself the box wedge with lift table would be the best route for me. I'm just trying to figure out if I can do a single wedge that's adjustable manually. That way I can have it for the knotty wood, then lower it down when I'm using the box wedge and it'll just become the center wedge. How to anchor the box wedge is a different story. That would certainly simplify the setup and save some cash on a cylinder, valve and hoses. I don't see myself switching setups that frequently other than crotch wood or possibly the larger hickories I have.

I'm going to go with standard plumbing for now and see how it performs. If I end up with a real issue I'll take a closer look. According to the calculator I found online the setup I'm thinking about is 8.4 secs cycle time if I use a 5" cylinder. The 4.5" cylinder drops that down to 7 seconds which is pretty fast.

my old boss used to say, "keep it simple stupid".  i agree with a wedge and a cylinder.  lots of variables like RPMs.  cylinder length, adding back stops.  you can do work while the detent is working.  you can get auto forward and detent valves ect. got a two-stage pump 28 gallon pump.  with a 5 inch cylinder, I work fine at an idle and talk above the noise.

there is a company named split eze.  they have great products and James is very knowledgably.  He will tell you if a bypass dump valve speeds things up...prob. not but reduce heat and wear and tear.  and they sell then as well.

It all depends on how resourceful you are for parts .It doesn't have be lightning fast like it's a race .Some think it is though for some reason .
Here is a picture of my homebuilt made from basically repurposed junk .Tilts,lays flat built solid as a battle ship and with a 5" cylinder will split anything .The cycle time will out run me at slightly above engine idle speed .That pile of EAB killed ash took me a little over an hour working at a snails pace because I need to rest every so often .It's around two face cords ,enough to last me 2-3 weeks .This thing is not pretty but highly functional .

i noticed this morning surplus center just started carrying a very economical new brand of single spool splitter valve. "dirty hand tools" is the brand and a valve is only $60 new.  ymmv, just thought id mention it.

You mentioned that you built a grapple for your tractor; I would build two splitters. The first for the tractor. I have split many a oversized round. Trying to roll them around under a vertical/horizontal unit is a pain. Having them up in the air is dangerous. Everyone worries about the wedge cutting off a finger. Reality is falling blocks will break your foot and turning the oversize chunks will mash your fingers between the round and the work table. Reduce the big rounds to halves or quarters where they sit with an inverted 3pt tractor splitter and then work the manageable size blocks to size with a horizontal.

Box wedge is great for productivity but does generate an enormous amount of trash and uses a bunch of fuel doing it. Red oak is heavy but actually splits fairly easy. Having been through a single wedge box store unit, skid steer inverted, Eastonmade 22-28 with box, 4 and 6-way wedges, Supersplit Heavy Duty Kinectic, and  Dyna SC-14 Processor what I found is the inverted single wedge for the big ones and the kinetic for the rest is the sweet spot for rounds. If you have a boiler and can use big chunks the multiwedge works fine but for stove-wood splits you will be re-splitting and the big hp/cylinder is a liability instead of an asset. If the kinetic is too fast for kids something like the fast cycle hydraulic design that Eastonmade markets to compete with the kinetics might fit the bill.

If you cut to the chase on home builds you are only limited by your pocket book and imagination .Plus of course your fabrication skills .
If you are selling fire wood in volume a faster unit ,perhaps even a box splitter would be better .However just doing enough to keep the home fires burning that would be way too much over kill in my opinion .

Now that's an interesting thought. Is there a skidsteer mount one? I could see driving around busting the big stuff then pushing it into a pile by the horizontal.

I have a different brand but same principal. The cylinder needs a push plate with the wedge fixed at the end so you can use the next block to push the ones that invariably hang on the wedge. I kept my SS model and bought a 3pt to SS adapter for the back of my tractor. Works fine although a little slower since much less flow.
