Cub Cadet 1604, 1606, 580, 582 Parts Catalog – Factory Documentation

If you are wrenching on a Cub Cadet 1604, 1606, 580, or 582, you already know the frustration of staring at a parts diagram from a third-party website that does not match what came off your machine. I have been turning wrenches for 28 years, and I have lost count of the times a knock-off catalog sent me after the wrong air cleaner element or governor spring. This manual is different. It is the genuine Parts Catalog printed by Cub Cadet – 112 pages of exploded views, factory part numbers, and serial number breaks that tell you exactly which part fits which machine.

Air Cleaner, Carburetor & Governor – Factory Breakdown

Flip to the Air Cleaner, Carburetor & Governor section (starts page 3 of the PDF). You will see each component called out with an International Harvester or Briggs & Stratton part number. For the 582 tractor, there are two critical serial number splits: below 700,000 and above 700,001. The air cleaner cover (ref #4) changes at that break. The carburetor mounting screws also split – IH-549459-R1 for later tractors. That information is not in any aftermarket summary. You get the exact gasket, float, and spring numbers from the OEM source.

A-Frame Hitch Adapter – Serial Number Thresholds

Another example: the A-Frame Hitch Adapter section (page 1) covers 582 tractors with serial number 720000 and above. The adapter package includes an IH-106998-C1 pin, 712-3015 jam nuts, and a BR-H-158 stabilizer plate. Missing that serial number cutoff will have you ordering a hitch kit that does not bolt up. The manual saves that headache. Part numbers like BR-D-146P (quick-attachable cotters) are listed with S/P/F codes – service, production, or field – which tells you if the part is still available through dealer channels.

7 Systems Covered – What You Can Actually Use

This catalog covers 7 major systems across the 1604, 1606, 580, and 582 models. Beyond the air cleaner and hitch, you get sections for the engine, transmission, steering, electrical, and sheet metal. Each section uses the same exploded-view format with a reference number table. For example, the governor section shows the speed control link (IH-78204-C1) and two different idle spring part numbers depending on engine serial number (79091712 and below vs 79091713 and above). That is the kind of detail you need when you are ordering parts online and cannot return a wrong spring.

Does This Manual Cover Your Specific Model?

Yes – if you own a Cub Cadet 1604, 1606, 580, or 582, this catalog is built for those exact tractors. The 1604 and 1606 share many drivetrain parts with the 580/582 series, but the manual differentiates them with separate exploded views and part number tables. For the 582, serial number splits are called out on multiple pages. If you have a 580, you will find the A-Frame hitch adapter listed under the 582 section with a note about serial number applicability – that means the same hitch part worked across both models after a certain build date. Always check the serial number notes before ordering.

Source Validity – OEM Print vs Aftermarket Reprints

This is not a scanned copy of a copy. AutoRepairManuals holds the largest collection of OEM shop manuals in North America. The file you get is a direct digital copy of the original Cub Cadet parts catalog, not a third-party compilation. Aftermarket parts catalogs often omit serial number splits, use re-drawn diagrams with missing callouts, or list “universal” part numbers that do not exist on the shelf. This manual carries the original International Harvester part numbers and the factory S/P/F codes. If you want to cross-reference with Automotive Industry Overview standards, go ahead – but the manual itself tells you exactly what to order.

Frequently Asked Questions

Can I use this catalog to order parts for a 582 with serial number below 720000?

The A-Frame Hitch Adapter section specifically says “582-Tractors W/sn 720000 & above.” For earlier 582 tractors, the hitch adapter will not fit. Other sections may have different serial number breaks – always check the heading on each page.
