Ben, it's part of my job to know weight and scale of roundwood.
In the following picture what we have is a 17 foot x 22" tip Rock Maple (Sugar Maple). The scale is exactly 324 board feet on the Doyle since I will get two 8' 6" logs., the total scale would be approx. 350 or so since I would probably pick up an addition inch in dia.on the butt log making it 23"
Now since one board foot of Rock Maple in log form weighs 14 pounds, what we have here is two 8' 6" logs weighing a total of 4,900 pounds.
Now if we take your 40" log, lol, and scale and weigh that, assuming it was 17 ft. with a 40" tip, it would scale 1296 board ft. and weight 18,144 pounds.
Now picture this in your mind, a 40" log comes up the just above my waist, yes I'm a sawed off runt, but comparatively it would be right even with Cahoons shoulder. Hahahaha.
The log was all the little tractor could handle on the loader and it bossed the tractor around a bit while I was skidding it. But it was fun.
Regardless, it was big of you to tell us you literaly broke in your 346, as most wouldn't for fear of ridicule, But I say you haven't worked in the woods unless you fubarred a saw or two.
The only thing I wrecked today was the fender light on the tractor, I was winching a large stem down a steep slope and as it gathered up speed in the snow, (tobaggan effect), it throttled a standing dead pecker pole, jack knifed and while I was running away it cold caulked the fender and broke off the light, however, when they made that one, they made lots of em'.
Ben, if you just had of told that log trucker how to unload those logs, this mishap would never have happened!
