Im sure that Warn is correct by stating that 500lbs of tension is needed on the spool. Its probably the first thing they ask when you
try to redeem their warranty.
Also, funny how Warn winch sales arent through the roof anymore. (Sorry Warn Vendors)
And do the math. When you first start winching you probably pull 5-10 wraps of 500+ tension before the vehicle even budges.
So why would you do this BEFORE the pull.
I have a 50/50 Daily Driver/Offroad truck. My winch gets regular use, its not a prop like most.
Myself and another truck just succeeded in recovering a Mitsubishi 4x4 100ft from the bottom of a cliff in Capitol forest,
by using a triple line pull via Warn M9500i (wire) and a double pull via Superwinch Terra 4500.
Also used was 60 ft of chain, 100ft of wire extension, 2-20ft tow straps (anchors), 10 bow shackles, 2 chainsaws and a 12 pack of Alaskan Amber.
I spooled 80 ft of line completely off my drum. Some sythetic doesnt have a screw at the end like wire or even attach to the drum. You just use a "pinch wrap" on the drum.
I respooled 6 wraps and maybe 50lbs pressure.
The other truck with 110ft of wire spooled out with 5 wraps left had no problem, because the following 10 wraps was most likely 500lbs +/- slack weight
in the system.
After all said and done. Neither of us respooled our trucks while attached to trees, using 2 people, or lumber.
Yes I did my best to not make my drum look like a Robins nest but only with minimal tension, while thinking the whole time of the irony, that hours prior I started posting on this silly tread about winch etiquette... thats probably scarying people away from buying or using their winches then doing good.
