I get some big WO, RO and Poplar logs from the tree guys sometimes. Logs 4-5 ft. dia. x 5 ft. long.
If I got my welding guy to make me some kind of splitting spear, would my D4 Dozer push that spear into that 5 foot White Oak log and split it?

Of course I would have to have the log against a tree to keep it from sliding.  :)

It could be done, but if it was me, just spend the money and get a D8. ;D

I don't think it's going to happen. Even a D-8 would have trouble doing that.

I think the splitting wage would have to be a long one or wide so the wood would go by the dozer blade. You would have to push the wage more than ½ way I think.

I don't think that your basal area is big enough to do that.

You may be right. Just trying to come up with an idea using the equipment I have.

Maybe a tall stump 4' with a steel wage on it and you can push the log to it. I'm been thinking of something like that and use my 690 JD. But I think the JD will pull the stump out.

Cut it as deep as you can with the chainsaw that you have and then use the teeth on your back-hoe and split it with that.  ;) It helps to put a couple of wedges in the saw groove so you can see where the teeth need to go.

When my Grandfather was logging he had a D8 and a D4 with a wedge welded on the blade. He could split 8 foot wide fir and cedar logs no problem. I imagine they're a lot easier to split than oak though. It's worth a try, probably need to get a good run at it  :D

Drill a hole in the side of it,put in about a half cup of black powder pack it with the sawdust ,shavings with a fuse and blow it in half,easiest,quickest ,and cheapest. And its fun also !!!! ;D

The D4 has between 10 and 15 tons of pushing force. Considering that a log splitter from the local big box store developes about twice the splitting force, the D4 may not be the best choice unless the wood is really straight grained,

OR

you get one heck of a running start.  ;D ;D ;D ;D ;D ;D ;D

So far "get a running start" is the most popular idea.  :D
Y'all are killing me......probably literally.  :D

loggah......I know you're gonna want pictures.  smiley_paparazzi They'll be Goat parts everywhere!  :D :D :D

boscojmb.....good info, I didn't know what the pushing power was.

Peter....it might work.  say_what

Bro. Been....Goat horn?  :D :D :D Good 1.

Jake....probably the less dangerous and something I can do tomorrow.

Do you have a 6 way blade on the D-4?

Starting with a chainsaw cut, or deep crack and a well designed wedge should do the trick.

D-4 is a little light but once you get the wedge started in you should be able to work it till it pops open.

Could alway mount a jack hammer to assist in splitting.

Not so sure I would put head down and get a run at it though ;D

6 way...8 way if ya count up and down. I may come up with a tall wedge.

I think Loggah has the best idea.Around here black powder splitting is pretty popular.

Excellent thread.  I have a client that wishes to have his 4ft+ diameter hard maple log quarter sawn.  I suggested that his best bet would be to find someone who has a swingmill.  You have given me an idea to build a giant wood-splitter though.  :D  A 4" diameter cylinder at 3000 psi would give you about 38,000 pounds of force.  A 6" diameter cylinder at 3000 psi would give you about 85,000 pounds of force.  Up the psi to 3600 and you can multiply by 1.2.  I don't know how much force is needed to split a maple or oak log though.   :-\
