You might as well use package twine as 1/4" chain. I broke my 1/4" chain numerous times just pulling rebar stakes out of the ground. (Old raised crib posts.) The smallest I keep around now is 5/16" #70 and up.
+1. I use 5/16"-70 when using the tractor and tie down on the trailer with 3/8"-70 and 3/8" high strength ratchets for my tractor weight of ~ 7200# with implements and loaded rear tires. Two chains on the front and two chains on the rear going from the tractor and over the implements to 5/8" bow shackles welded on the trailer frame.
