While I understand what you’re saying learning how to operate your tractor with a rear attachment (without hitting things) is part of the deal. I can’t think of the last time I ran my b2401 without something on the 3ph. At the least I have my 54” box blade which coincidentally is almost exactly the same size as a 48” flail mower. Rotary cutters swing quite a bit when turning but are great at mowing under trees. Flail mowers are pretty compact but don’t really mow in reverse but you can get them with manual or hydraulic offset which is great for ditches and mowing fence lines. Get the mower that best suits your needs and be prepared for the learning curve no matter what you select. I still think that a lawn tractor or used zero turn for the price of a Kubota mid mount mower makes more sense but that’s me.On a small yard, especially if you have trees and a fence, I would recommend a mid mower. Rear mowers swing out on turns, and I have seen a bunch of torn fence, skint trees, and even dented cars due to that. If you will have kids driving it and training to be operators, that is even more important.
The advantage that a rear mower has is that you can mow under a fence line (bobbed wire) better, and you can back into corners. MM always leave rounded corners where fences are.
I have a 2601, and I am thrilled with it. I will suggest getting pallet forks. You can not imagine all of the stuff you can do with a set of them, whether quick attach, or the ones that bolt on the bucket. They will make your life a lot easier!!
As for pallet forks I completely agree. Just get them, I use them more than a bucket. For me they’re a poor mans grapple but also handy for moving pretty much everything except gravel and dirt.
