Cub Cadet RZT50 Parts Catalog

If you’ve ordered a part for your Cub Cadet RZT50 and got the wrong piece, you know the waste of time. This factory Parts Catalog ends that. 47 pages of OEM exploded views and part numbers – no aftermarket guesswork. I’ve rebuilt these mowers in my shop for years. The first thing I grab when a RZT50 comes in is the factory catalog. Aftermarket cross-references miss seals, gaskets, and hardware. This one doesn’t.

Air Filter and Blower Housing Assembly (Page 1–2)

The first two pages show the blower housing, air cleaner, and pre-cleaner. Ref #1 is BS-695277 Housing, Blower – that part is unique to the B&S Intek. Screws are listed with sizes: BS-691005 for the housing, BS-691008 knob for the air cleaner. You see a pre-cleaner filter BS-273638 that most aftermarket listings ignore. If you’re doing a tune-up, page 2 tells you exactly which air filter cartridge (BS-499486S) and pre-cleaner to order. No need to measure anything.

Carburetor and Intake Manifold Exploded View (Page 3–4)

Page 3-4 covers the carburetor and intake manifold for the RZT50 B&S Intek. Every single part is exploded: the intake manifold (BS-699801), gaskets (BS-690949 and BS-699803), float bowl gasket (BS-698781), even the welch plug (BS-699810). There’s a standard main jet (BS-698784) and a high-altitude jet (BS-699820) – both listed with separate part numbers. The float needle valve (BS-698537) and float (BS-694914) are common failure points. I keep those on the shelf because this catalog tells me exactly which revision fits. The solenoid (BS-699728) is also here – a frequent no-start culprit.

Controls and Deck Lift (Page 5)

Page 5 shows the controls and deck lift assembly for RZT50 mowers with Mfg. Code B175 & After. This section is critical for deck leveling and control cable replacements. The illustration includes all brackets, springs, and fasteners. If you’ve ever had a deck that won’t raise evenly, this page gives you the part numbers for the lift linkage. Note: it separates parts by mfg. code – verify yours before ordering.

Does This Manual Include Torque Specifications?

No. This is a parts catalog, not a service manual. If you need torque values for the head bolts or carburetor nuts, you need the corresponding factory service manual. But for ordering parts – gaskets, seals, jets, and hardware – this is the only source you can trust. Aftermarket catalogs often omit the sealing washer (BS-695410) or the correct intake gasket thickness. This book doesn’t.

Why Factory OEM Documentation Matters

I’ve seen techs order a “universal” carburetor kit for an RZT50 and end up with the wrong float bowl gasket. The engine wouldn’t idle. The parts catalog eliminates that. Every screw, clip, and washer has a BS- prefix part number from Briggs & Stratton. The exploded view shows assembly order – crucial when you take apart the blower housing and need to know which screw goes where. For a $0.50 clip that holds the air guide cover, the part number is BS-691010. You won’t find that in a generic listing. For context on why OEM documentation matters in the automotive and equipment industry, see this Automotive Industry Overview.

Audience Fit: Who Should Own This 47-Page Book?

If you maintain one RZT50 in your home garage, this catalog saves you the trip to the dealer for a part number. If you run a shop, you need it on the shelf to quote jobs accurately. The parts list is all OEM – no reprints or third-party conversions. For background on industry standards for equipment documentation, see Automotive Industry Overview.

One short warning: do not use this catalog as a service manual. It won’t tell you how to adjust the valves or set the governor. But for ordering exactly the right seal, gasket, or jet – it’s the only way to be sure.

Frequently Asked Questions

Does this catalog include wiring diagrams?

No. It’s a parts catalog, not a wiring manual.

How do I confirm the part number fits my RZT50 with a different engine?

This catalog is specific to the B&S Intek engine. The first page notes “RZT50 B&S Intek.” If your mower has a different engine (e.g., Kawasaki or Kohler), this catalog will not match. Check the engine model number on the valve cover. The parts list covers blower housing, carburetor, and deck lift – but only for the Intek. For other engines, you need a separate catalog. Also verify the mfg. code on the deck lift section (page 5) – it applies to code B175 and after. If your serial number is older, the control parts may differ. I recommend calling the dealer with your machine’s serial number to cross-reference before ordering high-value items like the carburetor (BS-699807) which costs over $100.

That’s what this 47-page catalog delivers – the right part number, the right revision, and no wasted time. Access the Factory Manual now and keep it on your bench. You’ll never trust an aftermarket parts lookup again.
