There are factors that will effect this answer. What model the tractor is, what engine it has, what transmission, what condition, where it is being sold, what time of year it is being sold etc...
Right now, a typical Craftsman L-1000 in that year range and in good shape will sell for around 300-350 here in Cincinnati, Ohio.
