I've just GOT to say this. Twice as many bucket loads, twice as many hours and wear and tear with the 32..
1/2 as much lift on the bucket. The 45 handles many qucikattach implements with ease..
I don't care so much about a bigger BH. Mine is plenty tough and I have no need for longer than my 7 1/2' Backhoe. Though you may want to get a 12" bucket to go along with it for trenches..
Maybe it's just a personality thing.
You might check the width, length and turning radius to see how different it is. I also have to add. My 5' width is nice at times rather than a 6'.
Also consider hauling. On a 7000lb trailer, you could probably get the 32 and the BH on it. For the 45, you'll need a bigger trailer, bigger truck etc..
Of course, I rigged up to haul mine a few years ago, loaded it on the trailer once to see how it looked, and have never hauled it anywhere.
