Cub Cadet 1215 Parts Catalog

If you are wrenching on a Cub Cadet 1215 Parts Catalog, you need the factory breakdown. Not a third-party scan that blurs part numbers, not a PDF that omits washer sizes. I have spent 28 years torquing bolts and tracking down discontinued parts. When a homeowner brings me a 1215 with a blown mower deck belt, I grab the OEM parts catalog. That 60-page document is the difference between a two-hour repair and a two-day scavenger hunt. This is the genuine article – Cub Cadet 1215 parts listing for serial numbers 114,001 through 126,000. 60 pages of exploded diagrams, ref numbers, and exact part numbers. No guesswork.

What You Get in a Factory Parts Catalog

This is not a service manual. It is a parts catalog. That means every nut, screw, cartridge, and gasket is listed with a factory part number. Need the foam element for the air cleaner? Page 2 shows Ref #11 – BS-271962. That part is flagged as service item (S). If you order by that number, it fits. If you guess based on dimension, you will spend a Saturday returning wrong filters. The catalog also lists optional part numbers (P) for special applications – like the battery tray washers that take a 5/16 lock washer. No aftermarket cross-reference can match that level of detail.

Air Cleaner Assembly: Exploded View and Part Numbers

Turning to the air cleaner section, you get the whole assembly. Cover, knob, nut, washer, screw, cartridge, body, gasket, and element. Every piece has a reference number and a part number. The cartridge (Ref #7, BS-399806) is a service item – replace it, not clean it. The gasket (Ref #10, BS-270853) is a /P – meaning it can be purchased separately from the body. If you try to reuse a crushed gasket, you will get dirt past the filter. Cub Cadet engineers stamped those part numbers for a reason. Use them.

Battery & Mounting: Fastener Specs and Routing

The battery section (page 3-4) gives you the 12-volt battery (725-3061), the hold-down rods, and every fastener down to the 5/16-18 carr. bolts. Notice the lock washers – 736-0119 for 5/16 lock, and 736-3007 for internal-external tooth lock. Those are not interchangeable. If you substitute a flat washer, the rod will loosen and the battery will slide. The catalog also shows the drain hose (735-3027, 48 inches long). That hose routes water away from the chassis. Skip it and you will rust out the mounting tray. All here.

Brake Pedal & Connections: Finding the Right Springs

Brake assemblies on older garden tractors are a headache when parts are mixed. The brake pedal & connections page (page 5) shows every pivot, spring, and cotter pin. If the pedal feels spongy, you need the correct return spring – not a universal hardware-store spring that will sag after a season. The factory part number is the only way to get the correct rate. I have seen guys throw three different springs at a 1215 before buying this catalog. Then they order one part and done. That is the value of OEM documentation.

3 Reasons to Stick with Factory Parts Catalogs

One: part numbers are verified against the actual production run. Two: fasteners are listed by grade (GR 5) and thread (5/16-18) – no metric substitutions. Three: service intervals are coded (S = service, /P = optional purchase). Aftermarket parts lists often skip the “S” flag, so you buy a cartridge that is not meant for scheduled replacement. Not here. 60 pages of factory truth.

Source Validity: OEM Print, Not Aftermarket Copy

This is a direct scan of the original Cub Cadet publication. The page headers include the part supplier phone number (606-678-9623) – that is the old-school way. Each page shows the serial range and the revision date. No third-party redrawing, no lost resolution on the diagrams. If you need to identify a bracket or a bushing, the illustration is clear enough to read the ref number without squinting.

FAQ

Does this catalog include torque specs for assembly?

No. This is a parts catalog, not a service manual. It lists fasteners by size and grade but does not provide torque values. You will need the Cub Cadet 1215 service manual for those.

What serial numbers are covered?

Serial numbers 114,001 through 126,000. If your mower falls outside that range, some part numbers may differ.

Can I use this to order parts online?

Yes. The part numbers are the same used by Cub Cadet dealers. Enter the 7-digit code (e.g., 725-3061) into any dealer parts site and it will pull up the correct battery. No cross-reference needed.

What about the brake return spring part number?

Check the brake pedal page. The exact spring number is listed with a reference. If you do not see it, look up the assembly diagram for the pedal cluster. The catalog lists every spring, clip, and pivot pin.

You can waste an afternoon matching parts by eye, or you can let the factory do the work. Download the Factory Manual and keep a copy in your shop binder. Next time a 1215 rolls into your bay, you will know exactly which part to order.
