I have never owned an ATV but have decided to purchase a used one. I live on 40 acres, cut my own wood to heat my house. So I would use to pull logs, pull a wagon with cut wood, and general farm use. Also I plan on plowing snow so that sums up my needs. I will be looking at a 2003 Yamaha Big Bear 400 4x4 in a couple days. I need help as to what to look for with this model, maybe things that might be an indication of its condition. The ad says he just put a new battery in and the odometer doesn't work, it shows 881 miles. It also comes with a winch and plow and he wants $2100. Any help would be appreciated...thanks The pics look to be pretty decent shape.
