 Topic: Want to setup aux hydralics for log splitter
Posted: 28 Oct 2010 at 8:27pm |
|
Wonder if someone can get me headed in the right direction to setup an auxiliary hyd system to run a 3pt log splitter. I have a WD but there is no aux hyd ... like where do you hook up the pressure line and the return line? Can I use 2500 PSI cylinder? Any words of wisdom is much appreciated and pictures are even better!
If this has already been discussed just point me to it ... gotta believe this has been asked before but I can't find anything.

A Briggs 5hp and a 2 stage pump would be a better choice. The hydraulic system on the WD ran about 3500PSI but is a low volume system. If you try to use a a regular 4 inch diameter by 24 inch cylinder, you will probably run out of oil in the tractor before you stroke the cylinder out and you will have way more tonnage than any splitter will hold up to. If you add a 2 way valve it would probably have a pressure relief built in so you won't get the use out of the high pressure.
That being said, follow the lines that work your lift cylinders back to the valve on top of the hydraulic pump. You will find several pipe plugs in the valve housing. Plumb the pressure input side of your 2 way valve to one of these. You will have to run a return line to the hyd fill hole or to the drain plug. Someone on here recently said something about a return line to the setscrew on the belt pulley. You could probably add an extra reservoir and a return line to the belt pulley hole, just remove the pulley. I would add a filter on the return line somewhere.
One of the fastest log splitters around is one a guy built with a one way cylinder. He added 2 heavy springs ,one on each side, to return the cylinder. It works slicker than snot. No waiting for the hydraulics to bring it back.

I have to agree with charlie on most farm tractors built before the seventies the hydraulics are too slow to run a splitter efficiently we ran our of the tractor hydraulics for about 15 years before dad bought an engine and pump to put on our home built splitter wow talk about a difference best of luck Kev Card

I forgot to mention the cycle time of a splitter running on High pressure low volume AC system with a 2 way valve and a 4 in cylinder would probably be 2 to 3 times that of the Briggs with a 2 stage pump.

you got some goo info posted here.
Another option would be to set up a pto driven pump.
After messing with that idea in my foggy top side, I opted for a commercial tow one with an 8 horse Briggs on it. That thing will get with the program.
If you split a lot of wood, the cylinder travel time will start to get your attention.

It would be slow as stated and would be hard on the plunger type pump in the tractor, another option is to add a pto driven pump and run it that way. You should be able to get a pump that mounts directly to the pto from Tractor Supply,Northern Tool, and other suppliers.

You can also run an aux pump off the pto pulley mount or mount one attached to the front of the crank shaft. Done correctly you will have true live hydraulics then without tying up your pto shaft. But I do agree that if you are really going to use it much, get a small 5-8hp engine. I would not recommend a briggs unless its a vanguard however, which isn't really a briggs but a dihatsu. Other good choices are honda or Subaru/Robin(The ex series are really nice).

I would think tying up the PTO is not an issue if you are using a three point hitch splitter that would be in the way of the PTO already. The pump would uncouple from the PTO and stay with the splitter, just like a pump with a sprayer. If you have a need for live hydraulics for some other application that`s another story.

a self powered log splitter is the way to go. Much more flexible and small motors not expensive

when I built my splitter, I mounted the pump and tank on the splitter and I runt he pump off of the pto shaft via #40 roller chain. I did this so I can speed the pump up to get the flow out of it without having to thave the engine sit there wide open. It is a pull type on 2 wheels so I can run it with the D17 or any tractor with a pto...dont need a 3 point hitch. My problem with a Briggs engine is if its 0 out the D17 will start, will the briggs?? No problem tying up the pto, if I go to the woods I dont use the pto for anything anyway and if I want to, just pull the pin and undo the shaft and unhook from the splitter

My brothers 8 HP Briggs has an electric start and it does start at 0 degrees. The 5 hp we have on the family splitter has a rope start and can get stiff below 10 or 15 degrees but usually starts with a little effort. If it don't start, I have the idea that it's too cold to work outside anyway.

I never could see the attraction of a 3 pnt splitter. I'd put some wheels under it and set it up with a small engine driving a 2 stage pump. Make it so your power unit and reservoir are quick connect, a portable hydraulic power unit could have a lot of other uses. Just my 02 worth.

I'll try to get pics up of the 3pt unit I have. Its unlike most out there. For most people the stand alones make the most sense so If your going to have on on the tractor it has to have some advantages over the others. I can give you a list of pluses for the tractors unit. 1st is speed and I mean real speed. Mine is 6 secs full cycle time and since its 1 stage it never slows on any wood which can be a real times saver. 2nd being on the 3pt you can work at a comfortable height saving your back. 3rd mine has a sturdy fame with a 2' reciever to pull the wagon or trailer behind. 4th since my tractor runs on jet fuel its free to operate which BTW a desiel idling doesn't use anymore fuel than a briggs screaming at 3600rpm. And my unit does go vertical also. I'll pics up tonight or Tomorrow. BTW I recommend powering tracotr units off the Prince PTO pump and not the tractor hydraulic system. There are many good reason for this also.

Mine is old style but neighbor has the type that stands up. His is real nice for splitting big stuff right next to where you cut it. Saves lifting the heavy pieces.
Not sure if I would rather tie up the tractor on the splitter or keep it free to move wood around.
One advantage mine has is a old style wide wedge so it seldom will fail to split anything it buries into. His newer one is not as wide and moves with the ram, you have to keep an axe handy sometimes (not often).

My splitter tractor is a 5400 Deere and it has a BoDozer grapple on the front. So with the grapple and the splitter on the back its a fantastic combo. I'm not tying anything up. I can grab, lift ,load loads on the front and still pull the trailer behind on the log splitter. And when I do split I'm doing it at least 4Xs faster than a commercial stand alone unit.

I believe the pump used in earlier models is the same a D17 s4 which is low pressure so change the pump or change the relief value in the pump. the D17s4 used the side mount pump as did earlier versions

One of the biggest problems with tractor pump is to get good flow rates you have to run the engine nearly full rated RPM. IMO that sucks, and not just fuel, but its noisy too. PTO pumps put out 2-3xs the flow rate so you can practically idle the engine and still have great cycle times on the splitter. My tractor is 60PTO HP and it can't feel the pump even at idle.

you need to look at Butch(OH)'s splitter. It is WD powered(by the pto shaft) and looks pretty cool. Like he said, it cuts down on who borrows it this way

I have thought about a belt pulley drive for the B. That would be a hoot.

Thought I'd post a picture of an auxiliary hydraulic set up on a WD - I
was at the Orange Spectacular in Hutchinson this weekend and took some
pictures of tractors with this setup so I thought I'd share, just in
case there are some others out there that had never seen a aux setup
before ... like me. The stock aux line is closest to the battery box
and runs under it and to the back - see pictures. uploads/3420/IMG_0117.JPGuploads/3420/IMG_0118.JPG
