We are needing some advice! We have a model 104107 and do not know the year. From what I have found, it's early 70's, I think. We've been doing a lot of work on it (decals, paint, new battery-starter-fuel pump-3pc set of blades). The muffler is almost new. It's a beauty! We also have 2 look-like-new attachments: snow plow and grader. Ok....so that is what we have.....and it's all set to go to someone who will appreciate the power and the awesomeness of this machine. We want to get this listed (Locally? Across the States? Ideas?) and sold before the snow flies here in Iowa. So I'm asking for knowledge on what year this is, what y feel the complete package should sell for, and suggestions on placing an ad. I have more photos, if needed. Thanks much!!!
