Indeed thats a Kraut thing, wood can be sold in 1m lenght (which is about 3,3 feet) usally in 1sqm units. Dunno why its a 4feet length, has maybe to do with standard cut sizes. Like from 1meter you can do 5x20cm/4x25cm/3x33,3cm cuts..dunno if that makes any sense but thats my thought. Its also the cheapest wood here if you have to pay for.
I deal mostly with oak and can barely pick up some large diameter rounds (16 inch long) to put into truck. Some, I can't, I have to split them in two or more. I wonder how big a 4 ft log I could put on the truck. Hmmm... According to the following chart, a 1 ft long round of red oak, 12 inches diameter, weighs 49 lbs. I guess my math is right in that a 4 ft log would be 4 times that, lol! So, 196 lbs. I guess I could get that on the truck, I really don't know how much I can lift. Seems reasonable. Actually, as long as you can get a 4 ft log upright, you can lean against the tailgate and scoot it up and in. Interesting to contemplate hauling 4 ft logs out of the woods and stacking, instead of 16 inch rounds, but I question what I might accomplish by doing that. I would later still have to buck into 16 inch rounds and then split. What do you guys think of dealing with 4 ft logs? https://sherrilltree.com/content/legacypdf/Log_WeightChart.pdf
It doesn't sound too appealing to me, though I've done it scrounging wood that's already been cut. As long as you're not moving it a longs ways, it's manageable to roll them or flip them end over end. You won't catch me doing that with 18" diameter fresh cut oak though! I'm not sure how my grandfather did it. He was a mountain of a man, stubborn as the day is long but no dummy either. Maybe he was using equipment on-site to load up the logs. It's much easier unloading with gravity on your side anyway.
