Cub Cadet RZT50 2009 Parts Catalog

Nothing burns my time faster than a parts list that skips the reference number or mislabels a shoulder screw. You order the wrong part, wait three days, and it still doesn’t fit. That’s why I keep the OEM Cub Cadet RZT50 2009 Parts Catalog on the bench – 99 pages of factory-sourced part numbers, exploded diagrams, and hardware specs that match what came off the line. No third-party reinterpretation.

Cub Cadet RZT50 Parts Catalog – Deck Lift & Controls

The exploded view on page 2 shows every piece of the deck lift mechanism, from the lift shaft assembly (part 603-04160B) down to the .625-inch E-ring. You get the part number, the quantity, and the S/P/F code that tells you if it’s a serviceable item or a whole assembly. The lapbar lever RH and LH are both listed, and the torsion spring 732-0874 is right there with its dimensions. No calling the dealer to ask “is this the spring near the brake handle?” – you see it in the drawing.

What the Electrical Section Tells You

Flip to page 3 and you get the wire harness shown for reference only – but that reference is what keeps you from frying a solenoid. The layout shows the ignition switch, safety interlocks, and battery leads exactly as the factory built it. I’ve had customers bring in mowers that had been “rewired” by someone who guessed at pin locations. This catalog won’t teach you electrical theory, but it will tell you exactly what connector goes where and what part number to order when the harness melts.

3 Sections That Save You Phone Calls

First, the fastener chart: hex screws, lock nuts, shoulder screws – all listed with thread size and length. Second, the lift link plate and control hub assemblies – you can rebuild the entire steering linkage from the parts list. Third, the optional Kawasaki 17AI2ACP engine components are detailed in a separate section (not shown in the OCR, but included in the full PDF). Having the part number for a shoulder screw (938-0974, .375 x .38 x 1/4-20) means you spend five minutes ordering, not an hour hunting through bins.

Look Up the Right Fastener Size

You see a shoulder screw with a .498 inch shoulder diameter and 3/8-16 threads? That’s part 738-0143. The catalog lists it with the exact shoulder length and overall length. Torque values aren’t in this catalog – you need the service manual for that – but the hardware specs are dead-on. Use this alongside the service manual and you won’t guess at thread pitch or shank diameter. Your time is worth more than a stripped bracket.

OEM Printing vs Aftermarket Copies

Aftermarket parts catalogs often re-draw the diagrams, drop reference numbers, or merge multiple model years into one drawing. This is a direct scan of the 2009 factory printing. The part numbers are original Cub Cadet numbers, not cross-referenced to a universal system. You can walk into any Cub Cadet dealer, give them the part number from this catalog, and they will hand you the correct box. That’s the difference between a repair that lasts and a second trip to the parts counter. For more context on why OEM documentation matters across the automotive industry, see the Automotive Industry Overview. And when you’re working on other equipment, check the Automotive Industry Overview for standards on fastener marking.

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It lists hardware sizes but not torque values – you need the factory service manual for that.

Can I use this to order parts from a Cub Cadet dealer over the phone?

Yes – that’s its main purpose. Each part has a unique factory number (e.g., 703-05387B for the lapbar pivot bracket). Give the dealer that number and they’ll pull the exact part. The exploded views also help you identify which revision of a part your mower uses. I’ve had guys call me after ordering the wrong damper cylinder because they guessed at the length – with this catalog, you see the damper cylinder 727-04141 next to the lift linkage. No guesswork.

You’ve got a mower to repair, and you need the right part the first time. Access the Factory Manual and keep it on your tablet or print it out – either way, you’ll save yourself the headache of returns and phone tag.
