[I should think the large oblongs, like the rolls are the ones so big you can't move them on your own... :o]
that right saddad,you need a forklift
to move the large ones
At 18 I worked on a pig farm, tried to move one myself which was sat on a trailer wonky and tore the muscle in my right shouler. Still gives me problems 7 years later!
Learned how great forklifts were after that ....and asking for help :D
