I'm stopping after work to look at a 1997 Kubota, 4-W diesel, Land Pride rototiller & scraper, 3 pt. hitch w/bucket. Whatever that is. I really need something with a bucket, and a rototiller would be a great bonus. I called him and he wants $8K. I can't figure out where to find "blue book" prices for tractors! Any ideas?? Thanks!
