Nice looking steel and stick machine
2 buckets are better than one, if you can afford it, each for it's specific task, but....
How about bringing to a welding shop and have them widen it to the happy medium between high volume snow work and heavy dirt work.
Just a little bigger to cover your track, that would solve some of the PITN problems, like converting to QA or trying to sell your old bucket, trying to locate a bigger bucket etc.
Cost would probably not be to bad??? I've cut buckets and plows down with no problem, making them bigger will be more work but should be doable at a reasonable price, at the same time you can reinforce the top of the bucket.
Just a thought, worth a stop at a welding shop to ask, Good luck!
