Cub Cadet 1806 Parts Catalog – OEM Factory Parts Breakdown for S/N 756,300-799,999

You’ve got a Cub Cadet 1806 sitting in the shed with a busted air intake or a missing brake linkage. You pull up a parts site, type in the model, and get back a list of “compatible” parts that may or may not fit. That’s wasted money and time. This Cub Cadet 1806 Parts Catalog is the exact document your local dealer used before the computer systems took over. 86 pages of factory diagrams, OEM part numbers, and exploded views for serial numbers 756,300 through 799,999. No aftermarket reinterpretation. No “this should work” guesses. If you’re serious about keeping that 1806 running, start with the right paper.

Air Intake, Baffles, and Brakes – What the Catalog Covers

The catalog opens with the air intake system. On page 1 you’ll see the wing nut (KH-X-276-7), the air cleaner cover, the precleaner, and the element. Each part has a factory number, quantity, and a flag for service parts (S) or production parts (P). That matters when you’re sourcing replacements – a service part might be superseded, but you need the original number to cross-reference. The baffles and shroud section (page 3) shows the cylinder head baffles, blower housing kit, and all those self-tapping screws. The brakes & connections section includes the clutch release rod, linkages, and hardware. Every assembly is drawn with callouts so you can see where that odd little washer sits.

Why an OEM Parts Catalog Beats Aftermarket Blanks

Every time I see a DIYer buy a “universal” air cleaner or a knockoff brake lever for a Cub Cadet, I cringe. The holes don’t line up, the thread pitch is off, or the part isn’t rated for the engine’s vibration. This catalog was produced by Cub Cadet. The part numbers match the factory bins. If you walk into a dealer and hand them KH-X-276-7, they know it’s a 1/4-20 wing nut. Aftermarket catalogs often skip fasteners or group things into “kits” that leave you short. Here it’s all listed: page 5 has 23 numbered items for the brakes alone, including the clutch release rod and the specific screws.

Who Actually Needs This Catalog?

Home garage enthusiasts who own a Cub Cadet 1806. If you’re restoring a garden tractor, need to replace a cracked baffle, or want to confirm the correct 2.25-inch screw for the air cleaner base, this catalog saves you from ordering blind. It’s also useful for dealers and small engine shops that see older Cub Cadets. The 86-page count might sound thin, but every page is packed with part numbers you won’t find in a generic “1806 parts list” online. For other Cub Cadet models, here’s what we have: Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs – covers a different chassis but same philosophy. You can also check Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns or Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown if you work on multiple machines.

Using the Catalog – What You Need on the Bench

You’ll need a clean work surface and good lighting. The diagrams are clear but small. Each section has a header with the serial number range – verify your tractor’s tag before ordering. The part number format uses the KH prefix (Kohler/Harvester) plus a numeric code. Write down the exact number; don’t abbreviate. When you see a quantity like “4” for screw KH-X-67-98, that means you need four. Don’t assume one bag of assorted screws will do. The catalog doesn’t include torque specs – that’s in the service manual – but it does tell you the correct fastener sizes. For instance, the air cleaner base uses #10-32 x 0.5625-inch screws. That level of detail keeps your threads from stripping.

Safety and Assembly Notes – What You Should Know

Even a parts catalog has safety implications. Use the right fastener – using a SAE screw in a #10-32 hole will wreck the threads. The baffles section shows sheet metal screws; those need to be the correct length to avoid puncturing the blower housing. Always wear eye protection when removing rusted fasteners. The catalog lists washers and lock washers separately – don’t omit them. A missing internal tooth washer (#10) on the air intake elbow can vibrate loose and let unfiltered air into the engine. That’s how you cough up a valve job on a perfectly good Cub Cadet.

Frequently Asked Questions

No. It’s a parts catalog – exploded diagrams and part numbers. For service procedures, get the factory service manual.

What serial numbers does it cover?

Serial numbers 756,300 to 799,999. Check the plate on your 1806’s frame or engine cowl.

Is this a genuine Cub Cadet publication?

Yes. This is a direct scan of the original Cub Cadet parts catalog. No third-party edits, no reprints with blurred pages. Every part number matches what the factory used. The catalog was originally distributed to dealers for ordering parts. The pages show the same drawings that appeared in the dealership binder.

Yes. Each part has a factory number like KH-45-082-01. Plug that number into any online parts retailer. Just confirm the part is still available – some older parts may be discontinued.

Spending an afternoon chasing the wrong part because you trusted a “compatible” list is time you don’t get back. The factory catalog gives you the exact number. When you need to rebuild that 1806 from the ground up, this is the document that tells you what goes where and what it’s called. Access the Factory Manual now and keep it on your tablet or bench – it’s the difference between ordering once and ordering again.
