i lay ladder on ground and bolt all sections together.
i keep the ground section about 4 ft from tree.i pound 2 stakes at bottom ladder rail to keep it from sliding while lifting
then i pick up the platform section and which is 20 ft long from tree and i walk under it grabbing rungs as i slowly walk, 1 rung at time.
it slowly goes up in air then will head towards the tree.
you should have seen me try this when i did not bolt sections together,oh my, i would get it straight in air and 1 section would pop out
only problem is if you have laural on ground,so what i do is let it fall to tree from a good ground spot,THEN i slowly move it around tree where i want it..
takes me about 1 hr to put up a 20 ft stand by myself,other time is trying it out and adjusting it, that takes another hr getting it level
