Always wanted a roller (water filled), about 4 feet wide that I can drag behind my small tractor. Is a used water heater cord a good candidate for this project? Anybody done that?
Thanks,

What guage is the cord, Ivan? Even 6/0 is a pretty small roller!!!!
Friend is currently building a 14 foot packer - 30 inch diameter, 5/8"
thick steel - total weight including frame and carriage just over 2
tons, to drag behind his seed drill.

A water heater TANK might work - but you need to get an axle into it
to roll it - and not let the water out. A gas water heater with
bearing plates in the flue might work OK. I know a lot were made out
of both 15 and 45 gallon oil drums over the years - often filled with
concrete - when the steel rusted off you still had a roller.
