If you're doing it by yourself tie a rope off around the seat posts (or somewhere that as you pull the stand goes up nice and straight). Loop the rope around a branch higher than you want the stand to be (or put a screw step in higher than you want the stand to be..then toss the rope over that). Get down...pull the rope until the stand gets to the desired height. Tie the end of the rope off to anything...another tree...a screw step...anything. Climb back up...ratchet it down...and test it out.

With 5 Gorilla 3' ladder sections...and the stand...I can do it by myself in an hour. If my buddies are helping...½ hour tops.
