I ran onto a GT 10 this eveing and I have no idea what it's worth. I like the tractor but havnt really messed with many Bolens tractors. It's in pretty good shape. Runs good. Has 10hp Briggs with the geared tooth flywheel. It aslo has the mower deck, snow plow, snow blower, an extra hood, extra rear axle, extra pto box, and extra front axle. Paint is fare, not a show piece, but still nice for being factory. Where is the serial number located at, it was dark and I can go back and look at it. It has new tires on the the back and front. Thanks for the input.
