Cub Cadet RZT54 Parts Catalog – Factory OEM Part Numbers for Your Mower

If you have tried ordering a part for a Cub Cadet RZT54 and ended up with the wrong shoulder screw or a control rod that does not fit, you know the frustration. This Parts Catalog is the factory document that tells you exactly what part number goes where. 55 pages of numbered callouts, exploded diagrams, and OEM part numbers. No cross-referencing aftermarket lists that skip details. No guessing whether a hex screw is 3/8-16 x 1.75 or 5/16-18 x .75. The document is direct from Cub Cadet for the RZT54 with Kawasaki engine, 2010 and after.

What This Parts Catalog Covers

Diving into the first three pages, you get the Deck Lift & Controls section. Page 2 lists 54 individual parts—from the Deck Lift Shaft Assembly (ref #1, part 603-04160B-0637) down to the Extension Spring (ref #54, part 732-04432). Every part has a reference number, a factory part number, quantity, description, and an S/P/F column showing if it is a service part. The exploded view on page 1 gives you the visual layout so you can match the part to the location. Beyond deck lift, this catalog covers the entire mower: lapbar levers, brake rods, control shafts, pivot brackets, hangers, and all the hardware. You get the full 55 pages of OEM part callouts.

Why Aftermarket Parts Catalogs Fall Short

Aftermarket parts catalogs often lump hardware into generic bins—“screw, hex, 3/8” —and leave out the exact thread pitch, length, or finish. This factory catalog gives you the exact part number: for example, a Hex Cap Screw 3/8-16 x 1.25 is 710-3005, not a guess. The washer specifications are precise—Bell Washer .265 x .75 x .062 is part 736-0270. If you rely on aftermarket diagrams, you risk ordering a flange bearing that is .626 x .938 x .344 when you needed a different size. This catalog ends that risk. OEM documentation from Cub Cadet means the part numbers match the parts bin at your dealer.

3 Reasons You Need Factory Part Numbers

First: correct fitment. The RZT54 uses specific shoulder screws, torsion springs, and dampers. Part numbers like 938-0974 (Shoulder Screw .375 x .38 x 1/4-20) ensure the control hub mounts securely. Second: dealer ordering. When you call a Cub Cadet dealer with the factory part number, they pull the exact part off the shelf. No back-and-forth about whether it is the right generation. Third: compatibility with service bulletins. Factory part numbers tie directly to engineering updates. If Cub Cadet supersedes a part, the catalog shows the original number and you can verify the revision.

Using the Exploded Views to Identify Parts

Open page 1 of this Parts Catalog and you see a line drawing of the deck lift assembly. Each component has a reference number linked to the table. Start by finding the part you need on the diagram—the lapbar control rod, for instance, is ref #48. Cross that to the table: 747-05057 Lapbar Control Rod, qty 1. The S/P/F column marks it as /P (part). Check the hardware list: the clevis pin (ref #17, 911-0332) and cotter pin (ref #24, 714-04040) are separate order items. Never assume hardware comes with the rod. This catalog makes that obvious.

Audience: Who Should Own This Catalog

If you own a Cub Cadet RZT54 and do any of your own maintenance—even just replacing a deck lift handle or a damper cylinder—you need this. DIYers who rebuild decks will save hours matching parts. Small engine shops that service these mowers will keep this catalog by the workbench to avoid ordering mistakes. The document is 55 pages, manageable to print or keep on a tablet. It also benefits dealers who need to look up part numbers quickly for customers. Anyone tired of returning wrong parts should get this factory print.

Source Validity: OEM Factory Document

This is an original Cub Cadet factory parts catalog, not a third-party compilation. The phone number printed on page 1—606-678-9623—is a direct line for discount Cub Cadet parts. The diagrams follow the same numbering system Cub Cadet uses in their own service departments. Aftermarket catalogs often redraw diagrams and introduce errors. With this PDF, you are working from the source that dealers use.

Frequently Asked Questions

Can I use this catalog to repair my mower?

No. This is a parts catalog, not a repair manual. You need a service manual for procedure and torque specs.

Does it include engine parts?

This catalog covers the chassis and deck components for the RZT54 with Kawasaki engine. For engine-specific part numbers—pistons, rings, gaskets—you need the Kawasaki engine parts manual. However, this catalog shows the engine mounting hardware, spacers, and fasteners that attach the engine to the frame.

Are torque specs included?

No. Torque specs belong in a service manual. This catalog is for part identification only.

How do I order parts using this catalog?

Each part is listed with a reference number and a factory part number. Take that number to your Cub Cadet dealer or an online OEM parts retailer. The catalog also includes a phone number on page 1 for discount parts ordering.

If you have an earlier model, check the Cub Cadet RZT54 2009 Parts Catalog or the Cub Cadet RZT54 2008 Parts Catalog. For a different model, the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs might be relevant.
