Craftsman 24737037 lawn mower Parts

No. Craftsman mower blades are not all the same, and the correct blade depends on your mower’s deck size, blade mounting pattern, and whether you want mulching, bagging, or side discharge performance. For Craftsman model 24737037, the parts list shows a 21-in deck mulching blade.

What fits Craftsman model 24737037

Your mower uses a 21-inch deck, and the matching blade listed for this model is the 21-in deck mulching blade 942-0741A. For best results, match the blade type to how you mow (mulch vs bag vs side discharge) and keep the blade sharp.

Common reasons blades are not interchangeable

• Deck size (21-in vs other sizes)
• Center hole and adapter style (mounting pattern must match)
• Blade length and curvature (affects lift and cut quality)
• Blade thickness and balance (impacts vibration and engine load)
• Intended cut (mulching vs high-lift bagging)

How to choose the right blade type

Different blade styles change airflow under the deck and how clippings are handled.

Blade type	Best for	What you’ll notice
Mulching blade	Returning fine clippings to the lawn	Finer clippings, less bagging
High-lift blade	Bagging and strong discharge	More suction, fuller bag, can be louder
Standard blade	General cutting	Balanced performance

If you primarily bag clippings, confirm your mower’s bagging setup is in good shape (for example, a torn bag reduces airflow). The lawn mower grass bag 964-04154 is the bag assembly listed for this model.

Why it matters

Using the wrong blade can cause poor cut quality, clumping, extra vibration, and reduced bagging or mulching performance. The right blade, installed correctly and kept sharp, protects the deck, blade adapter, and engine.

Helpful DIY tips

• Review the blade and adapter diagram in the 24737037 owner’s manual before ordering or installing parts.
• Replace a bent blade immediately; sharpening will not fix a bend.
• Torque and orientation matter; install the blade exactly as shown in the manual.
• Use a blade removal tool if the bolt is stubborn: lawn mower blade removal tool.

On the Craftsman walk-behind mower model 24737037, the model number is typically printed on the mower’s ID label and also shown in the documentation as “Model No. 247.37037”. Use that exact number when ordering parts or looking up diagrams in the 24737037 owner's manual.

Where to look on the mower

Check these common ID-label locations first (wipe off grass and dirt so you can read it):

• Rear of the deck near the discharge opening or rear door area
• Top of the deck near the engine mounting area
• Side of the deck near the height adjuster
• Handle bracket area (where the lower handle bolts to the deck)
• Near the deck wash/nozzle area if your mower has a wash port

What number to use (model vs. engine)

This mower can also have a separate engine model number on the engine shroud. For parts lookup, match the number to what you’re repairing.

You’re ordering parts for	Use this number	Example you may see
Mower deck, handle, wheels, bagging, chute	Mower model number	247.37037 (use 24737037)
Spark plug, air filter, carburetor, recoil starter	Engine model number	Printed on the engine label

Tips to avoid ordering the wrong part

• Copy the model number exactly (use all digits; no extra spaces)
• If the label shows dots (247.37037), enter it as 24737037 for most parts searches
• Confirm the part by name and diagram callout in the manual before you buy
• If you’re replacing bagging parts, match the bag and frame style to your mower setup (rear bag, side discharge, or mulching)

Why it matters

Craftsman model numbers identify the exact deck, handle, and discharge configuration. Using 24737037 ensures you get the correct fit for items like the grass bag, side chute deflector, mulching blade, and hardware.

For a Craftsman 24737037 walk-behind mower, it’s usually cheaper to repair when the fix is routine maintenance or a single worn part; replacement makes more sense when the engine has major internal damage, the mower has repeated breakdowns, or repair costs approach half the price of a comparable new mower.

A practical cost rule we use

If the total repair estimate (parts + labor) is under about 50% of the cost of a similar new mower, repairing is typically the better value. If it’s over 50%, replacement usually wins.

Repairs that are usually worth it

• Blade service (sharpening or replacing a dull/bent blade)
• Fixing vibration caused by a loose or damaged blade (inspect and tighten hardware)
• Replacing worn grass handling parts (bagging or discharge components)
• Handle and control repairs (knobs, bail bar issues)
• Deck cleanup and prevention of grass buildup

When replacement is the better call

Replace the mower when you’re facing any of these:

• Major engine problems (low compression, severe overheating damage, internal knocking)
• Recurring no-start issues even after fuel and ignition service
• Structural damage after impact (deck cracking, persistent severe vibration)
• Multiple high-cost repairs needed at the same time

Quick decision table

Situation	Typical best choice	Why
Dull blade, uneven cut	Repair	Low cost, restores cut quality
Excessive vibration from bent blade	Repair (if limited to blade)	Safety issue; blade replacement is straightforward
Stale fuel, dirty air filter, fouled plug	Repair	Common tune-up items
Engine damage or repeated failures	Replace	Costs add up fast; reliability drops

Why it matters (safety and performance)

Your 24737037 manual stresses inspecting the blade for damage and replacing it with the correct OEM blade; it also notes that excessive vibration is a sign of damage that should be inspected and repaired promptly. Those safety-related repairs are worth doing right away, even if you’re still deciding whether to keep the mower long-term.

Helpful model-specific resources

• Use the 24737037 owner's manual for the maintenance schedule and safety steps (disconnect and ground the spark plug wire before service).
• If bagging performance is the issue, check fit and condition of the lawn mower grass bag 964-04154.

The Craftsman 24737037 is not a riding mower; it is a 21-inch gas walk-behind lawn mower. The operator’s manual for model 24737037 shows a document/form date of December 6, 2011, which is the best indicator of the mower’s production era.

How we identify the year for model 24737037

We use the model’s documentation and identification labels to narrow down the timeframe.

• Check the model and serial tag on the mower deck or rear housing
• Match the model number exactly: 247.37037 (often shown with a dot)
• Use the manual’s publication date as a timeframe reference
• Compare your mower’s features (21-inch deck, bagging, side discharge, mulching) to the manual
• If you have an engine model number, record it too; it helps confirm the build period

A good starting point is the 24737037 owner's manual, which identifies the unit as a 21-inch walk-behind mower and includes the manual/form date.

What “year” means (manual date vs. build date)

The manual date is not always the exact build year of your specific mower, but it reliably indicates the generation of the product.

Item you find	What it tells you	How to use it
Manual/form date (12/6/2011)	Product era	Confirms the model generation
Serial number on mower tag	Actual build batch	Use it to pinpoint manufacturing timeframe
Engine model/type code	Engine build info	Helps validate the mower’s timeframe

Why it matters

Knowing the correct model and timeframe helps us match the right Craftsman and MTD-style parts (like the mulching blade, blade adapter, or grass bag) so you avoid ordering a look-alike part that will not fit.
