Cub Cadet RZT42 Parts Catalog

If you’re halfway through a deck lift rebuild on an RZT42 and realize the aftermarket diagram has a wrong part number, you’re not just losing time – you’re chasing a ghost. I’ve seen too many jobs stall because someone trusted a generic catalog. This is the real thing: the Cub Cadet RZT42 Parts Catalog, 44 pages straight from the factory. No reprints. No copy. Every part number in here matches what Cub Cadet stamped on the assembly line.

Cub Cadet RZT42 Parts Catalog: What’s Inside

This catalog breaks down the RZT42 Kohler 17AA5B4G into two major sections: Air Intake Filtration (pages 1–2) and Controls and Deck Lift (pages 3–4). Each section has an exploded view with reference numbers, a parts list with factory part numbers, descriptions, and the quantity per machine. You also get the S/P/F column – tells you if it’s a service part, pack item, or frequently serviced component. No guessing needed.

Air Intake Filtration: Part Numbers and Descriptions

On page 2 you’ll find the complete air cleaner assembly. The catalog lists each component with its factory number:

• KH-20-096-04-S – Air Cleaner Cover
• KH-25-341-04-S – Cover Knobs (pack of 2)
• KH-20-083-03-S – Precleaner Element (service item)
• KH-20-083-02-S – Air Cleaner Element (service item)
• KH-20-094-01-S – Air Cleaner Base Kit
• KH-12-041-02 – Air Cleaner Base Gasket

If you’re servicing the air intake, those part numbers are what your dealer’s computer expects. Write them down, not the aftermarket cross-reference.

Controls and Deck Lift: What the Catalog Covers

Pages 3 and 4 cover the lapbar controls, deck lift mechanism, and brake linkage. Over 44 line items, from the deck lift shaft assembly (603-04160A) to the control hubs (748-04052). Each fastener is listed with thread size and grade. For example, screw 710-3005 is a 3/8-16 x 1.25 hex cap, GR5. You need that level of detail when you’re replacing worn hardware. The catalog also shows the correct shoulder screws, bearings (741-0225 hex flange bearing), and cables (746-0970 deck lift cable, 5.05 in. long).

44 Pages of Factory Parts Data

Every page in this catalog is a direct scan of the original factory document. The exploded views are laid out exactly as Cub Cadet intended. No redrawn illustrations that leave out a bracket or misplace a washer. The part numbers are the ones used on the production line. Aftermarket catalogs often change a digit or substitute a generic number. That’s a headache you don’t need when the mower is down and customers are waiting.

How to Order Parts Using the Reference Numbers

Each line item includes the Cub Cadet part number, description, and quantity. Use those numbers to order from any Cub Cadet dealer or an online parts retailer. The catalog even includes a discount parts phone number (606-678-9623) from the original distributor – though that number may be outdated, the part numbers are not. Cross-reference with your local dealer’s system. For other model years, check out the Cub Cadet RZT42 Parts Catalog as well as the Cub Cadet RZT42 2007 Parts Catalog – 40 Pages of Factory Parts Breakdown and Cub Cadet RZT42 2010 Parts Catalog – 47 Pages OEM. The part numbering conventions follow standard industry practices described in the Automotive Industry Overview. Understanding how OEMs structure their parts lists makes ordering anywhere easier. Automotive Industry Overview is also a good reference for terminology.

Does this catalog include engine parts?

Only the air intake filtration section covers engine-related components.

Can I use this to order parts from my local dealer?

Yes. Each part listed includes the factory part number and a description. Your dealer’s system will recognize these numbers. For example, the air cleaner element KH-20-083-02-S is the same number Cub Cadet uses in their own inventory. The catalog also includes a discount parts line (606-678-9623) though that may be outdated. Regardless, the OEM numbers are correct for any Cub Cadet dealership.

What if my RZT42 has a different engine?

This catalog is specific to the RZT42 with Kohler 17AA5B4G. Air intake and control sections may still apply, but verify against your mower’s serial number.
