Ooklaa,
I've done a lot of wood splitting. About 20 years experience. We heat a 2500 ft2 home with only wood all winter. About 3-4 cords/ yr.
Responding to comments on the Atom Splitter page:
Split from the bark side or in the upright position - yes, sometimes convenient. However, if you're burning in a stove (18-ish inch logs), you'll always be splitting from the ends. It is far better to cut the logs first, then split them, and I don't see how the atom splitter would even work then (it would spin the log). I've split logs about 4' long on the side using my traditional splitter with the rail turned to the vertical arrangement.
It can also be used as a loading / moving tool in that you can use it to pick up and load a truck with heavy logs, or use it to transport your logs to another location on your property - now that is true. I am limited to about 4' logs that I transport with a manual hand dolly. If you want to transport one at a time with your tractor, this might be a good idea.
It will pay for itself in a very short time because you are now able to split those big knotty stumps even with the stumps still in the ground - I purchased a 30-ton traditional log splitter and it splits everything. If I use a file to sharpen the blade, it will even slice a log sideways, so knotty is no problem. I never thought of splitting a stump in the ground. The atom splitter might be good for doing that .. although with a GC2310 tractor I just back hoe out the stumps, now.
It is Ideal for those who have out-door furnaces. - read this to mean that you can split big logs, not cut logs. If you want to split logs longer than 26" long, you probably have to split from the side.
Would operating the atom splitter need two people, or would you be climbing on and off the tractor each time to position the log?
When you buy a more traditional log splitter, buy one that rotates vertical. It is WAY more comfortable to sit on a stool (or a fat log) and process logs from left to right across the ground in front of you as the hydraulic piston goes up and down. I have my kids stack logs on the left and take them away to stack on the right. Upgrading to a 30-ton splitter now handles logs that I wouldn't even want to lift onto a horizontal splitter rail. Plus, by having the rail vertical, there is no way for split logs to fall on the engine or hydraulic pump of the splitter.
