A fellow I worked with passed last month. He had a 318 with snow blower and belly mower with power bagger. The tractor has 115 hours on the meter, and the meter is working. Mostly he used it for blowing snow. The mower & bagger were used maybe five times. I don't have any pictures yet, but the tractor and attachments are in mint condition (that's the way he kept everything).
So, what's it worth. I'm a Bolens collector, so I don't know about these JD machines' value.
