Cub Cadet 1730 Parts Catalog

If you’ve ever ordered a part for a Cub Cadet 1730 and ended up with something that didn’t fit, you know the waste of time and money. That’s why this Parts Catalog exists. It’s 73 pages of factory-sourced part numbers, exploded views, and reference codes. No guesswork. No translation errors. You look up the serial number range (207,401 – 239,300) and find the exact nut, washer, or air cleaner element. Every part has a Ref #, Manufacturer Part Number, Qty, and S/P/F flag (Service Part, Production Part, or Factory). That level of detail means you don’t cross-reference third-party lists. The 73 pages cover everything from the air cleaner to the brake pedal assembly and more. I’ve seen too many guys grab a generic parts list from a clipboard and end up with a bolt that strips. Don’t be that guy.

Factory part numbers only.

73 Pages of Factory Parts Breakdown

Page 1 shows the air cleaner assembly – nine numbered components including the cover, precleaner, element, base, gaskets, and fasteners. Each item lists its part number and description. For example, Ref #3 is KH-231032 Seal, Element Cover. The catalog notes whether it’s a Service part (S), Production part (P), or Field part (F). That matters because some parts were superseded mid-production. The factory serial number split – 207,401 to 239,300 – tells you exactly which revision applies. Without this catalog, you’re guessing whether your 1730 takes the older style elbow or the one with the integral gasket.

Brake pedal and connections fill page 3 through page 4 – 36 separate references. Things like cotter pins (714-0507, 3/32 x .75 inch), wave washers (736-3001), a brake rod (747-3131), and even the parking brake grip (720-3019). The catalog includes a note about serial number supersession on the switch actuator bracket (Ref 34) – only for tractors above 170,600. If you’re restoring a 1730 or servicing the brake system, this catalog saves you from measuring each washer with calipers or guessing which spring is the compression vs extension. The spring compression specs (0.58 OD x 2.00 Lg) and extension (0.50 OD x 3.97 Lg) are printed – that information alone can prevent a safety hazard if you install the wrong spring. This kind of detail is why factory catalogs beat aftermarket substitutes every time.

Air Cleaner Assembly: Ref Numbers and Part Descriptions

Look at the air cleaner section. Seven of the ten components are marked as Service parts (S) – meaning they’re the ones you’ll need to replace during normal maintenance. The precleaner (KH-45-083-01) and element (759-3359) are both S items. The catalog even includes a decal (KH-25-113-01) with instructions. That’s the kind of detail aftermarket catalogs skip. You get the correct screw lengths: one is 10-32 x 2-1/4 inch, another is 10-32 x 1-1/2 inch. Mix them up and you either bottom out or fail to engage. This is not a hobbyist document – it’s a factory library in paper form.

Brake Pedal & Connections: Factory Specs You Can Trust

Thirty-six parts across two pages. Each one has a material spec (e.g., 736-0270 Washer, Bell, .265 X .75 X .062 Thk). The catalog notes “For tractors w/serial no. 170,600 and above” on the switch actuator bracket. If you’re working on an earlier 1730, you need the old part. That’s the value of OEM documentation – it accounts for running changes. Ordering from a generic parts site without this info is a gamble. This catalog eliminates that risk.

What the Catalog Does Not Cover

This is a parts catalog, not a service manual. You won’t find torque specs, test procedures, or removal instructions. Use it as a companion to the factory shop manual – see related manuals like Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs for another model, or Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns for a larger reference. Also check Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown for older series.

FAQs

Does this parts catalog include exploded diagrams?

Yes. Pages 1 and 3 are exploded view illustrations with numbered callouts.

How do I find the correct part number for my 1730?

Start by checking your tractor’s serial number – it must fall between 207,401 and 239,300. Then locate the assembly you’re working on (e.g., air cleaner, brake pedal). Find the reference number on the illustration, then look up that ref number in the table. The catalog gives you the exact OEM part number. If you need a service part, look for “S” in the S/P/F column. Do not try to cross-reference with aftermarket numbers – the factory suffix designations are specific. For example, a brake pedal (703-1532) is only for this model range. Use the catalog as your master list before calling a dealer.

Can I use this catalog to order parts online?

Yes. Enter the part number directly into your favorite supplier’s search. The catalog’s numbers are original factory, so they should match. However, call the supplier’s phone number listed on page 1 (606-678-9623) if you’re unsure about supersessions.

Is this the same as an owner’s manual?

No. An owner’s manual has operation and maintenance schedules. This is strictly a parts identification document.
