Some charts show red oak weighing about 60lbs./cu.ft. at 70 percent moisture.
Got a little carried away...

Their are many variables with weight charts, they were invented to keep OSHA happy. Like I said, it could have be much lighter. Even at 60lbs it comes in at 4,665lbs.

Water weighs 62 pounds per cubic foot and wood floats.

I think you missed a decimal point there. 6.2 lbs/cubic foot.

Nope. 62.4 #/ft3 for water. A totally fresh, wet log may float (some don't), but (for oak) isn't very much lower density than water...maybe 58 to 60 or so #/ft3.

Nope. It's 62.4 pounds and I left off the .4 because I figured it's more of a appropriate number.

At 36" (avg) diameter = 4665 lbs.
At 38" (avg) diameter = 5198 lbs
(when using 60 lbs/cu.ft.)

Hope the "pop" was nothing.
Seeing how thread is already a bit distracted on wood density and log weights, may I also ask OP, what is the value ($) of a log like that is? As a log, and as rough cut lumber? I turned a nice oak into fire wood (many, many of those logs. I still feel guilty, but I don't think I lost too much money, compared to the time and hassle to sell one tree as logs, or get it cut up into lumber, and finding substitute for the firewood.

When I did the weight calculator from MossRoad above I got a number less than water. To be blunt- if you are getting a weight higher than the weight of water you will need to verify your source and or math.
If the dimensions are correct and the calculator is close the log was at or near the max the loader is designed to lift- which makes sense right? In order to lift near double the FEL capacity as some charts or math have suggested you would need near double the hydraulic pressure or bigger cylinders or different geometry- right?
I'm enjoying the discussion and honestly had no idea they had log weight charts- so I'm learning too. Good luck finding the pop sound.
