Huh, I thought 4wd was to get you places you really shouldn't be, and then having recovery equipment on hand was to get you back out when you got stuck...The whole purpose of having 4WD is to enable you to 'reasonably' go places you could not traverse in 2WD. Not as a safety/rescue measure for using 2WD only.
Learn the capabilities of your 4WD, drive judiciously....and you'll avoid becoming stuck the majority of the time.
Hmm, wonder how hard a receiver winch install would be on my little BX... Probably easier than the alternator and battery upgrade, but Curtis sells a bolt-on, high-amp alternator kit for this tractor for the cab A/C units.
