Put one on my duramax about two years ago. It's fairly protected, and makes oil changes a breeze. Zero leaking. I don't think I'd bother for a tractor, as oil changes are so infrequent, but I change the oil on my truck around 6k miles, which seems like it's every 4 months or so... I warm it up first, and then crawl under and open the valve. No burns, and pretty fast drain that way. Change the filter once it's cooled off a bit, then top it off and write down the mileage. Done. Seems so much easier than dealing with the drain plug...
