Here's another option that works for me:
Disconnect the arms that lift the deck.
Put the tractor in 4 wheel drive.
Turn wheels fully to the left.
Put two 2x10x18 wood pieces, stacked one on the other, in front of each front tire.
Drive onto the wood pieces.
Disconnect drive shaft and front attachment.
Slide the deck out the right side by wiggling front and rear ends past the front and rear tires.
I do this on an asphalt drive.
