Re: Wagner Little Giant Tractor
First of all, welcome to the forum, Samantha!
It certainly is an interesting looking tractor, but I can't find much on it on the internet.
Looks to be a 1960's tractor from the styling. Also looks pretty complete except for the muffler.
To aid in your sale, I woudl recommend you wash it up well, see if you can get the tires holding air, verify if the engine turns freely, even go so far as to drain the old gas and oil, and put in fresh to see if it will start. Obviously running will bring more interest.
As I said, I don't see a lot of talk about these on the internet, so I don't know if they are highly prized or not.
It is an interesting looking tractor which a collector might value just because not everyone has one.
On the low end, not running, I'd say $150 (that's my personal max for ANY non running tractor). Running, maybe $500.
Hopefully, there may be someone to come along and be able to give you something more authoritative.
