Log weight?

[silverking]

Ya know the old saying about famous last words being "Hey watch this", well I'm about to be either just another hard working person (at best) or a complete idiot(god I hope not) at worst. Anyways, my question is what do you think a log weighs that is 20' long by 48" around?

Just so you have an idea of what I'm doing I am going to try to retrieve a log of a fallen tree that is 50' down a bank in about the worst possible place for trying to retrieve it.
On my property this size tree isnt easy to find and I would like to get it for a hobby project.

Is that 48" diameter or circumference?

Any other large trees around that you can use to anchor a pulley system?

If you mean 48" diameter it will weigh 10 to 15K# depending on type of wood and wetness. If circumference then roughly 1/9 [1/pi squared] that weight.

A 48" beech log weighs a lot more than a 48" poplar log.

I bucked a 48" log of solid, healthy, fresh blow-down, white oak for firewood couple years ago. After splitting a couple of rounds and watching my truck sag as I loaded I decided to do a load check - total weight of the splits from one 20" length round was just shy of 1k. So 20' - 12k.

By saying 48" around that would be about 16" diameter- so using the link provided it looks like on the average it would be about 1500 lbs but could be WAY more or less depending on the wood species.
I get amused when I constantly see locals advertising a cord of firewood that will be delivered in a pickup truck in one trip....a true cord of green firewood can easily weigh 3 tons!

I'm guessing about 24" diameter, either red oak or hickory, it is laying on a almost vertical bank with the head in the river and the uprooted base facing uphill.
I have not climbed down to it yet so the id and measurement is guess work. I plan on roping it off onto some other trees further up the hill and cutting the head off. The Log could be cut into two 8' lengths and still be ok for my purposes. I intend to rope, strap and chain between my tractor and full size four wheel drive. If it seems like I am making some headway then great, if not well, back to the drawing board. I really am hoping its no more than about 2000lbs, thinking around 100lbs to 120lbs per foot.

Sheer stubborness is known for getting many difficult jobs done under less than ideal circumstances and I'm known for being stubborn at times. I'll get a pic or two posted and keep you up to date on my progress or failure.

Thanks,

I pulled a old used power pole a couple weeks ago that was at least 12" - 14" round and 25 feet long... no problem and I used my smallest tractor.
