This original operators manual gives you information on operating your equipment, as well as basic maintenance guidelines. Lots of illustrations, and instructions to help familiarize you with the Allis Chalmers Coil Tine Attachment for the 2300, 2500, and 2600 Disk Harrow, 1200, 1300, and 1350 Field Cultivators, and 1600 Chisel Plow (only Coil Tine Attachment covered). It is worn from use but still in good condition.
