Cub Cadet 2150 Parts Catalog – 83 Pages of Factory OEM Parts Breakdown

Nothing burns billable time faster than ordering the wrong bolt. You pull a part, find it’s half a thread off, then wait three days for the correct one. That’s why this 83-page Cub Cadet 2150 Parts Catalog exists. It’s the factory-published breakdown for tractors with serial number 326,006 and up. Every part number, every fastener size, every optional bracket is listed exactly as Cub Cadet designed it. No aftermarket guesswork. No “looks about right.”

42″ Deck Assembly Breakdown – Two Serial Number Ranges

This catalog splits the 42-inch deck into two separate assemblies: S/N 359000 and below (page 1–2) and S/N 359001 and above (page 3). Why two? Because Cub Cadet changed the belt covers, tension handles, and hinge brackets after that serial number break. Order a part from the wrong section and you’ll get a shoulder bolt that doesn’t fit the roller pin. The factory numbered each reference – from 1 (skirt extension) to 48 (lock washer) – and gave you the exact part number, quantity, and service/part status codes (S/P/F). You can see it right in the OCR excerpt: Ref #10 is a carriage bolt 1/4-20 x .50, part number 710-0167. Simple. Direct.

83 Pages of Verified Factory Part Numbers

Eighty-three pages. Not 90, not 70 – 83. That’s the exact page count Cub Cadet published for this model range. Each page covers a specific assembly: the 42″ deck, the hood and grille, the steering column, the hydrostatic drive, the electrical harness. You get exploded-view diagrams with numbered callouts and a matching parts table. The table includes the part number, description, quantity used per assembly, and whether it’s a service part (S), production part (P), or both (F). If you need a new tension spring for the chute deflector, look up Ref #31 – spring extension .88 OD x 6.12, part 732-0262. That’s a factory number. Cross it to any distributor and it will match.

Parts Catalog vs. Service Manual: The Difference

Understand this: a parts catalog is not a service manual. This document won’t tell you how to remove the deck or what torque to apply to the blade bolts. What it will tell you is the exact part number for every nut, washer, belt, pulley, and bracket that came on your Cub Cadet 2150. If you’re doing a restoration or a full rebuild, you need both. The parts catalog saves you the headache of buying a generic blade that lists “fits Cub Cadet 42″ deck” but is actually for a different spindle spacing. You want the genuine 734-0973 wheel, deck, 5-inch diameter? It’s in here. You want the shoulder bolt with .498 diameter x .340 length (738-0143)? Listed. No substitutions.

Use the Serial Number Cutoff Correctly

Grab your tractor’s serial number before you open this PDF. The catalog covers Cub Cadet 2150 units with serial 326,006 and up. If your tractor is older, you need the pre-326,006 catalog. Inside, you’ll also find deck serial number splits (359000 and below vs. 359001 and above). Ignore those cutoffs and you’ll order the wrong belt cover or lift rod. The factory printed these splits for a reason – use them. Check your deck’s serial plate (usually stamped on the front left side of the deck housing) to confirm which section to consult.

Where This Manual Fits in Your Library

If you’re already working on a different model, the Cub Cadet 21121C29025 Parts Catalog – 73 Pages of Factory Specs covers a similar chassis. For older units, the Cub Cadet 984 Parts Catalog – 128 Pages of OEM Factory Parts Breakdowns might be what you need. And the Cub Cadet 81, 21121C290248 Parts Catalog – OEM Factory Breakdown fills another gap. Beyond Cub Cadet, the wider Automotive Industry Overview explains why factory data matters for any machine with moving parts – same principle applies to lawn tractors. The Automotive Industry Overview article goes into deeper detail about standardization.

FAQ

Does this parts catalog include torque specs?

No. This is a parts identification manual, not a repair guide. Torque values for blade bolts or deck spindles are in the Cub Cadet 2150 Service Manual. The parts catalog lists only part numbers, descriptions, and quantities.

How do I know if my tractor’s serial number is covered?

Look for the serial number plate on your Cub Cadet 2150. It’s usually riveted to the frame near the rear hitch or stamped on the right side of the transmission tunnel. If the number is 326,006 or higher, this catalog matches your tractor. If it’s lower, you need the pre-326,006 parts catalog. For the 42-inch deck, check the deck’s serial number – if it’s 359000 or below, use the first deck section; if 359001 or above, use the second section. These splits are critical; ordering a part for the wrong serial range will waste your time and money.

You’ve got the serial number, you know which assembly needs parts, and you’re tired of guessing. Access the Factory Manual and get the correct part number the first time.
