Nice 45° day for splitting. Yea, tell me about short daylight days, under 6 hours here Good to get it split when green if it's twisted, It won't get easier as it dries It's "Split it" , "Stack it", "Dry it", "Burn it"
Google "firewood fingernail test". You push a fingernail into wood and drag it sideways (parallel to the nail). Thumbnail works best in end grain. In softwood your nail leaves a track sunk in the nail's path. In dense wood, no groove. Say I see some rounds laying along a road and don't recognize the species so don't know if it's worth picking up. A house key or similar works too.
I cut loads of maple and it looks just like that, split it green if not its much harder without a splitter.
I had a ranger like that. I know what you mean by downshifting. I figured mine was putting about 70HP to the ground. Great trucks though.
