Cub Cadet GT2550 Parts Catalog

If you are turning wrenches on a Cub Cadet GT2550, you need the right part numbers the first time. I have seen guys order an air cleaner element based on a parts store cross-reference and end up with the wrong precleaner because the manual they used left out the kit structure. That is how you burn a Saturday and a half-tank of gas running back to the dealer. This is the OEM Parts Catalog for the GT2550, covering tractors with manufacture date codes K015 through K018. It runs 95 pages, and every page is built around factory exploded diagrams and genuine Cub Cadet part numbers. No third-party renumbering. No guesses.

Air Intake and Filtration: What the Parts Catalog Shows

Open to page 2 and you see the air intake system laid out with every fastener and seal. The catalog lists a kit for the air cleaner cover (KH-24-743-08) that includes refs 2 through 5 and 12. That means you are not buying a knob and a seal separately when the cover assembly is what you need. The element itself (KH-47-883-03-S1) comes with the precleaner already included. If you try to order those pieces individually from a generic listing, you will miss that detail. The catalog breaks it down by S/P/F – service, part, or fast-moving – so you know which items the dealer stocks regularly. That matters when you are sitting on a dead mower.

Battery, Electrical Components and Switches: Part Numbers That Matter

Electrical gremlins are the worst. This section covers the main wire harness (629-04158), the PTO switch (725-04175), the key/module switch (725-04227A), and the indicator/hour meter with a split for K017 before and after. Page 4 shows the entire electrical schematic as a component map. If your GT2550 won’t crank, you can trace the interlock switch (brake), the seat switch, the reverse snap-mount switch, and the relay in one glance. The catalog also gives you the exact fuse sizes – 25 amp and 5 amp – so you are not guessing. I have watched a guy put a 30-amp in a 25-amp slot because the aftermarket book said “25A” without a part number. This manual kills that problem.

Blower Housing and Baffles – Mfg Date Variations

Cub Cadet changed the blower housing layout for K016 and after. The catalog separates those sections. If you order parts for a K015 tractor using a manual that lumps them together, the baffles will not line up. Page 5 shows the blower housing assembly with 14 components, including the hardware. You get the exact screw sizes – Hex Flange M6 x 1.0 x 16, M6 x 1.0 x 40 – from the air intake section. That level of detail is why factory catalogs exist.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, aftermarket parts lists often renumber parts to avoid copyright. That renumbering introduces errors. Second, aftermarket catalogs omit the kit structure – they list the knob separately when the factory includes it in a cover assembly, costing you more money. Third, OEM catalogs include manufacturing date splits like K015 vs K016 that aftermarket houses ignore. You pay more upfront for the factory document, but you save on the second trip to the parts counter. See the Cub Cadet GT2550 2009 Electrical Schematic for the wiring diagram complement to this catalog. Also check the Cub Cadet GT2550 Parts Catalog for the exact same document in a different format. For a different model range, the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs covers a similar architecture.

Does This Manual Cover Torque Specs or Only Parts Numbers?

This is a parts catalog, not a service manual. It gives you part numbers, quantities, and exploded views. Torque specs are not listed here – those belong in the shop manual. What this catalog does is tell you which fastener goes where, and which gasket, seal, or O-ring you need to order. If you need torque values, pair this with the factory service manual. But for ordering parts, you will not find a more accurate source. Every fastener on the air cleaner base bracket has a part number (KH-24-126-21 and KH-24-126-130-S). That kind of specificity saves you from buying the wrong length.

Source Validity: Factory Cub Cadet Print, Not a Copy

This file digitizes the original Cub Cadet parts catalog. It carries the factory layout, original part numbers, and the S/P/F flags. You see the source: www.mymowerparts.com and the discount parts line. The PDF is 95 pages scanned from the OEM binder. No redactions, no renumbered pages. If you want to understand automotive industry standards for aftermarket vs OEM documentation, the Automotive Industry Overview gives background on why factory specs matter. Or read the Automotive Industry Overview for a broader view.

What makes this different from a generic parts list?

This is the OEM catalog with factory exploded diagrams and original Cub Cadet part numbers. Aftermarket lists often renumber parts or omit kit assemblies, leading to wrong orders.

Will this work for any GT2550 regardless of manufacture date?

It covers K015 through K018. Earlier or later mfg dates may use different components. The catalog shows splits where applicable, like the blower housing for K016 and after.

Does the catalog include the Kohler engine breakdown?

Yes. The air intake section references Kohler parts (KH prefix). The catalog does not repeat the entire engine exploded view – it assumes you have the engine manual for internal components – but all engine-mounted parts like intake manifolds and gaskets are listed.

How do I know this is not a reprint?

It is a scan of the original Cub Cadet publication. The PDF retains the original layout, page numbers, and the source website watermark. No content has been recreated or renumbered.

You have read through the system breakdowns. You see the part number depth. The only move now is to get the document on your workbench. Access the Factory Manual and start ordering the right parts today.
