I always have my loader on and only install my bucket when needed.
So the bucket is always off when I mow.
To remove the bucket unless a quik attach would be about the same as the loader. Most people can easily remove them in less then five minutes as well as reattach in about the same time. Do make sure as noted above that you find a level area not just for the loader but the immediate approach as well so all is level.
agree with chim, easy on easy off fel, to make things easier i built a cart using 2in square tubing with 4in steel casters to hold fel when off so i can move it out of way while not in use and easy to wheel over to tractor to install.
