SIL's mate has a French ex-mil crane weighs 23 ton. It is bogged down in a field. SIL has a Yank Rio with a 10 ton winch. Another mate has a 432. They have tried winching using the 432 as anchor, sideways because of space, but it dragged the 432 & they stopped before the tracks came off!! They don't want to try to drag out with the 432 as it would cause one hell of a lot of damage to field & can't use the 432 to pull the Rio backwards because of space, the two vehicles won't fit unless the take away a tree & telegraph pole. Any ideas?
