Yes. Often they are loaded by a tractor that loads onto the chain. It’s is fed into a trough that feeds it to a cross cut. Tgg he e chunk you cut falls into to 4-8 wedge splitter. It gets split and belt fed into a truck fed, wagon, trailer, etc…. One of those bad boys.My buddy and I went 50/50 on the DR back in the day. However, when it shells out I may look to see if there are any firewood processors in this area. Are you talking about the unit that picks up a log, cuts, and splits all in one operation? I've see these on youtube hooked onto a skid loader.
Maple is like my holy grail of firewood around here. I generally mix some elm, aspen, and pine when burning, but every few years I'll get a lead on some maple.Good heart exercise I do as well but in the woods I cut the big hard maple that won’t crack after a few swings into 1/4’s these days.
The elm that split well here is red elm but the big trees are long gone now.Elm is actually my favorite wood to burn. Splits well and those "hairy" fibers and splinters make awesome tinder and kindling. It also burns very hot, less BTU than oak or hard maple probably, but hot and very clean.
Mulberry is my second favorite due to availability around here and very high BTU as well. However, IME it takes an extra 6 months to a year to age/dry. I typically get my stove hot with elm and keep it hot with mulberry.
We have various evergreens available in limited supply around here with cedar the most common. They light fast and burn faster, but are much sootier. Good tinder and kindling.
