Up for offers is a pair of John deere operators manuals for the Steel Portable and Hay Elevator, and Row Crop Cultivators. The row crop cultavator book is for models A2,T2 and A4, T4. In the book they show a JD 3010 tractor. I'm not sure if that would be late fifties or early sixties. But we know which was the popular tractor at the time. The elevator was on steel wheels. Guessing 30's early 40's. Both books are used origiinal manuals. They have smudges on the covers or marks here and there. But are very good and usable. Throwing in a free bonus brochure. Caswell Loader in color ad. Please look at the pictures. They show it better than I tell it. Please ask any questions you may have. We ship in the US only. We ship via USPS first class mail. Buyer pays shipping. We will combine items for savings on shipping. Thanks for looking and happy offerding.
