How can you roll a huge log?

Are they like these? They look useful but I've never seen them in use over here. To get them out of the log I believe that you put a steel bar through the eye and turn them and they loosen easily?

That’s the stuff. Used them for the cable hoist on the logsplitter. Didn’t use them for long as I eventually found the log tongs easier to use.
Never tried twisting them out. Didn’t learn that until I had already stopped using them.

 

Don't overthink it. Dig two or three holes under it (for bar clearnace) and cut it down to more managable lengths.

 

And they had a bucket tractor right there

That’s how my neighbor gets logs on his sawmill. Single rope and a boat style hand winch mounted on a pole that slides in the log stop bracket. Whatever the proper name for that is.
Works much better than I expected it to.

 

I sneeze at the log, and it rolls over.

 

Log, not dog.

 

Speaking of big logs, try this!

 

Yes, log.

 

My kid loved that show. LOL
