International Harvester 20C Field Harvester Manuals

Which Manual Do I Need?
There are 3 main types of International Harvester Field Harvester manuals, each with a specific purpose. Some manuals combine types (i.e. Parts + Operators, etc.), but the basic function of the manual types remain the same and are as follows:

• Service Manual (SVC) - The service manual (a.k.a. Shop manual or Repair manual) tells you how to take the International Harvester Field Harvester apart, fix it, and put it back together. It is written in the language of a mechanic and may include valuable detailed information such as specifications, torques, ranges, etc. If you are serious about repairs or restoring, you need the service manual.
• Parts Manual (PTS) - The parts manual has exploded views of all parts on the Field Harvester giving great detail on assembly and disassembly. It also includes a guide for ordering parts. It picks up where the service manual leaves off. If you do your own repairs, you need the parts manual.
• Operators Manual (OPT) - The operators manual (a.k.a. Owners manual) is the book that came OEM from the manufacturer when the International Harvester 20C Field Harvester was purchased. It gives the owner/operator instructions, shift patterns, capacities (anti freeze, crankcase, oil, hydraulic, etc.) and adjustment procedures (brakes, clutch, etc.). This book is a critical tool for operating and maintaining your machine.
