You need to check with some of the local sporting goods dealers around your area. But in all reality I doubt that you will find anyone that is willing to rent you one just due to the liability issue of it.
One other thing you might look at is buying one. There are some good cheap ones out there that you could buy for about the same price that you might be able to rent one for.
Lone Wolf Treestands is a newer high end stand. They are incredibly light which has great advantages when carrying it through the woods. You also can't go wrong with Ol'Man. They have been around for awhile and their new Drone with the Hex drive is very convenient being able to level yourself while up in a climber.
I will admit, I love deer plots.
I love planting... even the garden at home.
What I do not like are high cost farm implements.
I found myself in need of a cultipacker for clover and other small seed - but could not find a decent deal on a small unit.
OK, fine... I will make one!
The materials were very simple... some plastic corrugated sewer drain pipe, some metal, 2 bearings and some concrete and you are in business!
I cut the pipe, in this case, to 46" wide - as I intended to pull this one...
