A few weeks ago, I had a large hickory brought down and cut into 16" rounds. The larger stumps, I'm guessing, have a 20" diameter. My plan was to split the rounds for use for next year. Yesterday I though I'd get started on splitting the rounds by using my Fiskar maul. No matter how hard I swung down, the maul would literally bounce off the stump. It was like trying to split rubber. It took 20 whacks to split one of the smaller rounds. What am I doing wrong? Is it even possible to split hickory this fresh? Would a hydraulic splitter be more appropriate? Many thanks if anyone can help me feel less dumb about this. H.
