Bubba,
I have a Hobart also, and shred my own cheese. You can probably save 15 cents a lb if you shred it yourself. Only drawback is the labor and storing it in containers.
If your using 500lbs of mozzarella, you’ll save 75 bucks a week.
Take into consideration your gunna need to buy the attachments for it and also utilitzing the machine more often.
I shred every 2 days and roughly 125lbs each time.
