Straightening a hay spear

I have a very old, very used and abused Vermeer 3 pt hydraulic lift that I use to stack  the second tier of round bales in the barn. It is old and slow but it works, except one of the spears (2"x48") is bent down about 3 inches. So it does not hold bales as securely as I would like. The spear is welded into the old critter so I can not easily change it. Any ideas how to straighten this? Will heat make it weak and useless?

My barn only holds 24 second tier bales for the horses, so it is not worth buying a FEL.

 

Thanks
