You can R & R the MMM without tools and it gets much easier with practice.
Since the MMM weighs in at around 220 or so lbs, it's not the easiest implement to move around but Kubota did make the anti scalp wheels to pivot which helps in rolling the MMM into position to mount/dismount.
The 60" MMM is too wide to just simply roll under the BX23 and hook up, you've got to roll it under the tractor at an a angle, then once the front mount has cleared the right front wheel (when viewed sitting in the seat) you can straighten it up and roll it the rest of the way. Once it's lined up I then hookup the driveshaft then hook it up to the rear points then sinch it up by connecting it to the front mount.
Figure your 1st time to mount or deismount the MMM will probably take 20-30 minutes. But once you've got the routine down it should take maybe 5-10 minutes or less, without tools.
Some folks use the FEL to raise the front wheels high enough so the 60" MMM can be slide straight in. I haven't tried it that way yet so I can't comment on how easy it is, perhaps some will who does it will.
Since I don't have the 54" MMM I don't know whether it'll slide straight in or not.
For me it's not that big a deal to R&R the MMM and since I do alot of close in cutting around trees and other obstacles, I prefer the MMM.
A rear mount is definitely easier to R&R bit isn't as useful for cutting around obstacles, it's better suited for wide open spaces.
Good luck
