Cub Cadet LT2042 Parts Catalog – 72 Pages of OEM Factory Parts Breakdown

You know the drill. You’re elbow-deep in an LT2042, and the air cleaner base is cracked. You pull the old part, squint at the casting number, and start scrolling through eBay listings that say “fits LT2042” but don’t match the bracket. That’s time you don’t get back. This 72-page factory Cub Cadet LT2042 Parts Catalog kills that guessing cold. It’s the same book the dealer uses to pull stock from the bin. No aftermarket re-draws, no “compatible with” nonsense. Every exploded diagram is an OEM photo-litho print. You get the exact part number, the exact description, and the exact quantity your machine needs. If you’re fixing a lawn tractor on a Sunday with the parts house closed, having this on your phone or tablet keeps the job moving.

Air Intake And Filtration: Factory Parts Breakdown

Page 1 shows the entire air cleaner assembly from knob to gasket. You’ll see the KH-54-755-01 knob-with-seal kit and the KH-24-083-02 precleaner element. The diagram labels each screw—M6 x 1.0 x 16 flange hex, part number KH-24-086-53-S. If you need the intake manifold, it’s there with the carburetor gasket and two O-rings. When you order parts from this catalog, you’re matching what Cub Cadet put on the line. No cross-referencing, no “this should fit” headaches. Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs covers a similar platform if you’re working on a different model.

Does This Catalog Cover the Electrical System?

Yes, and it does it page by page. Page 3 lays out the battery, harness, relays, and switches. You’ll see the main wire harness (629-04111), the 25-amp fuse (725-3243), and the five-amp fuse (725-04008). The diagram shows the interlock switch for the brake, the snap-mount reverse switch, and the PTO switch. If your hour meter quit or the ignition key/module needs replacing, the part number is right there: 725-04227. This catalog doesn’t tell you how to test the circuit, but it tells you exactly what to order so you don’t end up with the wrong terminal cover or relay.

72 Pages of OEM Part Numbers

Seventy-two pages. That covers the blower housing and baffles, the steering assembly, the transaxle, the mower deck, and every nut, bolt, and grommet in between. Each section starts with an exploded view and then a table with ref numbers, part numbers, quantity, and S/P/F (service/optional/optional?) codes. You want the screw for the air cleaner base? Page 2 gives you KH-M-651040-S – hex flange M6 x 1.0 x 40, four needed. No hunting through generic hardware assortments. Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns offers that level of detail for a larger machine if you need it.

Get the Right Part Number Before You Order

I’ve seen guys order a “universal” air filter element because the box said it fits a dozen engines. Then it’s too tall, the cover won’t seat, and the tractor starts sucking unfiltered air. This catalog lists the element as KH-47-083-03. That’s the factory spec. You pick up that number and you get the right depth, the right seal, and the right precleaner fit. Same for the battery—925-1707D. No guessing amp-hour rating or terminal orientation. The catalog gives you the exact replacement. Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown follows the same principle if you’re working on that series.

Battery and Electrical Components: What You Need

Page 4 covers the battery retainer strap (723-04016) and the silicone gasket for the battery compartment (721-0342). If your wiring harness got chewed by a mouse, you’ve got the main harness part number. The diagram shows the red terminal cover (725-3007A) and the black terminal cover (725-0340). You also see the power receptacle (12V) – 725-2003. That’s the one for plugging in a charger or accessory. All the clips, ties, and push-mounts are listed with their own part numbers. No more sorting through your used tie stash hoping one fits.

Source Validity: OEM vs. Aftermarket Parts Catalogs

I’ve been burned by aftermarket parts catalogs that redraw diagrams and drop reference numbers. They save a buck by omitting updated parts or using blurry scans. This is a genuine Cub Cadet factory publication. The OCR excerpt shows the original phone number for discount parts and the mowerparts.com watermark. That’s a dealer-level source. When you order from this catalog, you’re basing your purchase on the engineering that left the factory, not some third-party guess. Automotive Industry Overview gives context on the standards behind OEM documentation. Automotive Industry Overview reinforces that same point.
