Straigthen out front loader bucket leading edge

I recently purchased a 655d loader/backhoe. The leading edge of the front loader did not have a cutting edge and it had a slight bow with the center being lower and higher towards the opposing ends.

Is there a way to straighten the lower out so my new cutting edge sits flat across the hole width of the bucket? Any suggestions aside from a sledge hammer?

Thanks in advance for any help!
