ECN Forum Forums General Topics of the Trade General Discussion Area Pulling out old feeder wires underground

I have 4 350 mcm wires about 250 feet underground from switchgear to vault. I have tried everything to pull these wires out, they don't move an inch. Anybody have a method I can try? The 4 inch conduit needs to be reused for the school facility upgrade.Plus I have salvage rights for the copper.
