What is powering hydros? I see no belts.
I like rear opening and how much stronger hydros suspension is. Not just a L shaped bracket. Of course, you will have to check on those bolts ever so often, knowing Hustler.
Bottom protection is also good.
I say you need better tires. You will have no traction on wet grass+wet clippings with those turf tires. I took mine off right away, mower was like Ginkana car. Drifting.
