Cub Cadet 1620 Parts Catalog – Factory Part Numbers for Your 1620 Tractor

You have your Cub Cadet 1620 Parts Catalog in your hand. That means you are done guessing which part fits. This is the genuine 76-page factory document, not some aftermarket reprint that uses a generic drawing and hopes you don’t notice. I have been a tech long enough to know that when a DIYer calls me asking why his new air filter doesn’t seat, it is because he bought a part based on a vague online description instead of using the OEM part number. This catalog gives you the exact ref number, part number, and description for every component on the 1620. You want the air cleaner element? Page 2 shows Ref # 6, part 759-3359. That is a fact, not a suggestion.

Air Cleaner Assembly – Page 1 Breakdown

The very first page of this Cub Cadet 1620 Parts Catalog lays out the air cleaner assembly with 15 separate items. You see wing nut KH-X-276-7, cover KH-45-082-01, element cover KH-52-082-04, and the precleaner KH-45-083-01. Every part has a Service/Production/Fastener code (S, P, or F) so you know if it is a serviceable item or a production-only piece. If you are rebuilding a 1620 that sat in a shed for ten years, you need that seal KH-231032 (Ref #3, listed as /P). Without the catalog you end up with a parts store filter that is close but not right. Close costs you time and money.

Battery & Mounting: What This Catalog Covers

Page 3 starts the battery & mounting section. You get the 12-volt battery (725-3061), the tray (703-1144), both left and right battery cover rods (711-3142 and 711-0222), and the drain hose (735-3027) that is 48 inches long. All hardware is there: carriage bolt 5/16-18 x .75 long (710-0451), washer specifications like .281 x .500 x .056 (736-0142), and lock washers (736-0119, 736-3007). If you are replacing a battery tray, you need to know which rod goes on which side. The catalog shows left-hand rod is Ref #4, right-hand rod is Ref #5. That saves you an extra trip to the dealer.

Brake Assembly Exploded View

By page 5 the catalog breaks down the brake assembly. The exploded view includes every spring, lever, and bracket. Without OEM drawings, you can mis-align the brake linkage and end up with a tractor that won’t stop. This catalog prevents that. You get the reference numbers, the fastener torque specs are listed elsewhere in the manual (you need the full manual for torque values – the parts catalog gives you the components).

3 Reasons to Trust OEM Parts Catalogs

First, aftermarket catalogs often substitute a generic part that fits 50 models. This Cub Cadet 1620 Parts Catalog is model-specific. Second, OEM part numbers are what dealers use – you can cross-reference them anywhere. Third, the exploded view comes directly from Cub Cadet’s engineering drawings. I have seen techs waste three hours because a reprint omitted a washer. This catalog does not omit anything. For other Cub Cadet models, check out the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs or the Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns. If you have a different model, the Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown might be what you need.

Using the Ref # and Part Numbers Correctly

Every page in this catalog has a reference number column and a part number column. Do not order by the reference number – that number changes between model years. Order by the part number: for example, the air cleaner base KH-52-094-06. Write that number down, call your dealer or search online. The catalog includes phone numbers for discount parts (606-678-9623 and 606-561-4983) on page 1. Also note the S/P/F code: S = service part (you can order it), /P = production part (may be obsolete, but you can try). This is not some third-party summary – this is the actual factory doc. I trust OEM data over any aftermarket website. If you want broader background on the industry, read the Automotive Industry Overview or the Automotive Industry Overview – but for your 1620, stick with the factory parts catalog.

Frequently Asked Questions

Does this catalog include torque specifications for the engine?

No. This is a parts catalog, not a service manual. It lists every part and its part number. Torque specs come from the factory service manual for the 1620.

How do I find the part number for the brake band?

Turn to the brake assembly page (page 5). The exploded view shows each part. Match the reference number to the table. The part number will be there. If you cannot read the tiny print, zoom in – the PDF is high resolution.

Can I use this catalog to order parts for a 1620 that was made in 1992?

Yes, this catalog covers the 1620 model. However, there were production changes over the years. Always confirm with your tractor’s serial number. This catalog gives you the parts as originally specified. If your tractor has been modified, you may need to cross-reference.

Is this a genuine OEM PDF or a scan?

It is an original OEM PDF – 76 pages, no watermarks, no third-party logos except the reference to mymowerparts.com on the bottom of the pages. The part numbers and diagrams are exactly what Cub Cadet published.

You want a part for your Cub Cadet 1620, you need the correct number. This catalog is the only way to get it without calling five dealers. I have been turning wrenches for 28 years, and I do not touch a job without the factory documentation. Access the Factory Manual and keep it on your tablet or print it out. Next time your 1620 needs a new air cleaner element or battery tray, you will have the exact part number in thirty seconds.
