yep i cut trees for quite a few years on the powerlines and it does work we would pull some big *** trees with 2-3 guys by going around a tree and thru a loop tied in the rope and it would double our pull power...same as block and tackle (pulley setup)

 

thats rough....when i had my 400ex, i rolled it down a hillside to a roadside ditch with about 4 ft of water in it....and the machine was upside down....oops. maybe i should consider getting a 4x4 instead of trying to trailblaze with sport quads....at least i was able to flip it back over myself...haha
its amazing the thing still started after that...that machine isnt real finicky i suppose..

 

Had one of the 4wd kawi mules for a year or two. Went down a wet 2 tracker about 300 yards and it got really wet and deep. Ended up stuck in a 2 and 1/2 foot mudhole. Got 2 tow trucks (friends) stuck trying to get it out. Eventually just had 12 fully grown men walk it out of the hole. Lots of fun.
