    I’m finally at a point in my life where splitting wood by hand is no longer fun. Maybe “fun” is the wrong word, it was never fun, but now it feels like work.

    I decided to try to see if I could make the plow hydraulics on the 3b work for splitting at least the most monotonous of the woods I burn. Dry lodgepole pine is actually so easy to split, it’s hard. If you hit it too hard, it blows apart and cartwheels down the hillside.

    I made the platform for the wood to sit on out of 3 1/2” square tube, and it fits into the brackets on the frame for the plow with two hitch pins, and two chain supports link onto the A-frame.

    My first attempt was a failure. The cylinder just doesn’t have enough force on the downstroke to do the job.

    So, I moved the cylinder to the back side of the A-frame and modified the arm to work as a cantilever. If my math is correct, the “push” has 46% greater force than the “pull”.

    After this pic, I swapped the lines at the valve so the controls weren’t backwards, and I re-routed the hoses so they weren’t kinked.

    I ran some more linkages through the grill with a handle so I can operate it from out front.

    I used this for about an hour this morning and got all my wood split. I love it.

    I could see how harder woods will give it fits, but for $90 I can get a direct replacement cylinder that replaces this 2” bore with a 3” bore that would increase the force by 125%. At 2000 psi, a 2” bore should apply 6280 pounds at the shaft, and a 3” bore should apply 14,130 pounds. This is reduced some by the arm being longer on the wedge side; lengths I don’t have at the moment to do the math.

    The downside is, it would be slower by about the same factor. I do like the speed.

    But as you note, slower. No free lunches. Cycle time is a big factor for me, it adds up when doing large quantities. For years I kept using a hand maul because it was so much faster than hydraulic splitters.

    I suspect increasing the power might also mean upgrading other areas, such as the suspension chains, etc.

    Cool project. :)

    Great innovation! Looks like a match to your fairly straight-grained lodgepole pine.

    If you get into gnarly, tight-grain stuff a flaring, wider wedge & a means to pull a occasion stubborn piece off the wedge may be necessary! I have a 22-ton hydraulic splitter that gets challenged on occasion by cut-to-18"-length gnarly hardwoods.

    The 3b chasing someone with the axe cycling would make for a good low budget horror movie.

    Someone has to remind our jeeps that life isn't all fun and games!

    I took the kids in the blue jeep up into the woods yesterday to get one last load of wood. This massive Grand Fir was too convenient to pass up. It was pushing 36” at the base, and it shook the ground pretty good when it landed. I could only fit the middle 2/3 on the trailer. I’ll go get the rest next spring with the truck.

    With wheels this big, the support chains weren’t allowing me to split where I wanted, so I made a trip to Ace for some bigger chain and clevises. I capped the tubing, mounted the chain to the ends, and welded new tabs onto the cage.

    Now it should be able to handle anything I can throw at it.

    You cannot stop.breaking wood since you have this tool. Deforestation risk.

    Well, this thing just became even more useful. I made an attachment that bolts onto the wedge…
