I know tow trucks (rollback wreckers) hook a chain to the rear of a car then winch from the front untill tight. Anybody know if the brake on a self recovery winch is safe for this purpouse? I'm guessing it would be, espically a mechanical one like on an 8274, and I am almost certain one of the old RE worm drives would be safe, but what about one of the planetary winches like an XD9000 or the new MM? I am mostly wondering about the Warn XD9000 (because that's what is on my trailer) and the Warn M8274-50 (because that's what is on my truck). Anybody have any FACTS? Stories are ok too, but facts would be better.
