on our 970 the bottom half of the front pivot had broken off and nobody knew it. The story my cousin gave was he was culimulching (probably faster than he shouldhave been) and was pulling up a steep end of the field. With the front end lite, it hit a furrow and the front end folded up underneath the tractor and down she came. All I saw was the aftermath which looked similar to yours in a way. The oil pan got a hole punched up through it, and I'm pretty sure we replaced the front and rear pivots.
Unless you've been looking for a reason to part with it I'd think it would be worth fixing?? It might not be cheap, but if nothing else was broken up I'd have a hard time calling it quits on the old girl.
