looks to be a Husky Gardner, but im not the best at the Bolens models. I see it has a custom fuel tank and a serious tire/wheel issue. I guess it depends on what your going to do with it and wether there are any other attachments to go with. If i had one already then i might trade, but if its your first one and you want to work it or show it, id keep my g8.
Its definitely a Bolens Gardener
Normally I would say ditch the G8 and grab the walk behind, but this one looks like it needs a ton of work to get going. Your missing some parts as well and parts for these models are harder to come by than the power Ho and Versa-Matic series.
Looks like there is a sickle hiding in the dirt as well.....
Did he give you any model numbers?
