If you're just going to put it back on again, you can leave the 3pt hitch off.
There are some videos on youtube showing how to remove and install it. I don't remove it like they do using the BH to pull itself off the tractor. That requires more finesse with the BH than I have. I just raise up the BH so it's not hanging on the pind and make sure the front of the subframe has dropped down so the tractor won't hit it (you may need to push down lightly with the bucket), and drive the tractor out a few inches.
I place the BH on cribbing under the main frame between the outriggers.
The lynch pins that keep the latch pins in place can be tricky to remove. There's not enough room to flip the wire bail over like normal but if you pull the latch pins back a little there's just enough room to pull the bail up enough to let you slide the lynch pin out. (the latch pins are the L shaped ones that hold the latch bars in place over the frame tube)
I keep meaning to reverse the frame bolts that are in the way to give me another 1/4" of room but since I have a system that works I have not gotten around to it.
