 The person who invented this metal-linked sock for the Dozer's tires Aced their middle school's Macramé elective class.  It probably took that old guy an hour or better to install the tire chain. Now multiply by 4. I put snow chains on an Autocar plow/dump/hauling shit for the county, truck on just the back four and they were easy to put on, after ya master it. They weighed 35lbs. each. Those are in the hundreds probably.  0:44   well, ahh, pretty sure that is a Loader (Payloader) . . . .  Excavators already have a linked track, no tires.
