Time for a new tractor! I would like to get a tractor for the next 20 years. I found a JD425 13 years old. not sure of the hrs. I think it was in the 500's. asking price is $4500 with plow. also looked at a new x300 with plow for $1000 less. Capabilities aside, which tractor will still be running in 20 years? or whicvh will be cheaper to own and enjoy for the next 20 years.
