The jack on my utility trailer has had it. Time to replace. For a couple of reasons, I feel like I HAVE to have a drop leg jack. Unfortunately, no one seems to make one (of decent quality) that is also designed to swivel. At best the trailer shouldn't be carrying more than 3,500 pounds, so pretty much any jack out there will do. This is basically the design of what is on the trailer now: It sure seems to me that I should be able to cut the existing jack off, and simply (nothing is simple, but I'll adapt) weld a square one in it's place on the swivel. The overall lengths seem to be about the same. As long as the foot is no larger than what is on the present jack, I don't see why this might not work. Am I missing something? I'd use something like this: https://www.tractorsupply.com/tsc/product/bulldog-heavy-duty-topwind-square-drop-leg-jack-with-base I'm open to other jacks, but it seems the market is pretty limited in what is available...like all are made by one or two companies, just rebranded.
