Craftsman 247377441 lawn mower Parts

Common problems on a Craftsman walk-behind mower like model 247377441 are no-start or hard-start conditions (often fuel, spark, or air related), poor cutting (dull or damaged blade, uneven wheel height), excessive vibration (loose or bent blade), and self-propel issues (belt routing, debris, or a worn belt). For model-specific safety and operating checks, use the 247377441 owner's manual.

Most common symptoms and what usually causes them

• Won’t start / hard to start: old gas, dirty carburetor, fouled spark plug, dirty air filter
• Runs rough or idles poorly: spark plug gap issue, dirty air cleaner
• Excessive vibration: loose blade/adapter, unbalanced blade, bent blade (often after hitting debris)
• Uneven cut: wheels set at different heights, dull blade
• Won’t mulch well: wet grass, grass too tall, dull blade
• Won’t self-propel: debris in drive area, belt misrouted, worn drive belt

Quick checks we recommend (in order)

1. Fuel: Drain old gas and refill with fresh fuel (stale fuel is the most common seasonal issue).
2. Spark: Inspect the spark plug; clean/replace and set the correct gap per the engine manual.
3. Air: Check the air filter; clean or replace if dirty.
4. Blade and hardware: With the spark plug wire disconnected, check blade condition and tightness.
5. Drive system (self-propel models): Clear debris around the drive mechanism and inspect belt condition.

Troubleshooting guide (symptom to likely fix)

Symptom	Most likely cause	What to do first
Excessive vibration	Loose or bent blade	Tighten hardware; replace bent blade
Uneven cut	Wheel height mismatch	Set all wheels to the same height
Won’t mulch	Wet/tall grass, dull blade	Mow dry grass; sharpen/replace blade
Won’t self-propel	Debris or worn belt	Clean debris; inspect belt routing and wear

Self-propel not working: parts that commonly get involved

If your 247377441 is a self-propel version, belt and drive issues are the usual culprits. A common replacement is the lawn & garden equipment belt 954-04260 (listed for this model’s drive system).

Why it matters

These problems are more than convenience issues. A loose or damaged blade can cause unsafe vibration, and incorrect wheel height or a dull blade can lead to poor cut quality and extra strain on the engine and drive components.

The model number for this Craftsman walk-behind mower is 247377441. On the ID tag it may appear with punctuation (for example, 247.37744 plus a final digit), so we recommend matching the full number on the mower’s label to the model list in the 247377441 operator’s manual.

Where to find the model number on the mower

We typically see the model/serial label in one of these spots:

• On the rear of the deck housing near the discharge opening
• On the back panel near the rear wheels
• Near the handle mounting area on the deck
• Occasionally under the grass bag area or rear skirt

How the number may be written (and what it means)

Craftsman and MTD-built walk-behind mowers often print the same model in slightly different formats.

What you see on the mower	What it means for parts lookup
247377441	Full model number used for parts diagrams and ordering
247.37744X	Same family; the dot is formatting and the last digit can vary
247.37744*	The asterisk indicates the last digit varies by version/production run

Why it matters

Using the exact model number helps us match the correct parts diagrams and hardware for your mower’s deck, handle, and drive system. Even small version changes can affect items like the drive belt, wheels, or grass bag fit.

Quick tip if you are ordering common parts

If you are replacing bagging components, match both the model number and the part listing:

• Lawn mower grass bag 964-04154 for the bag itself
• Confirm the frame style if your bag uses a separate frame
• Check fasteners and mounting points before ordering

The Craftsman model 247377441 is a gas walk-behind lawn mower, not a riding mower; its operator’s manual for the 21-inch mower series is dated November 17, 2017, which places this model family in that timeframe. For the exact build date, use the product ID label information referenced in the 247377441 owner's manual.

How to identify the exact year for model 247377441

We use the mower’s identification label details (model and serial information) to narrow the manufacturing date.

• Look for the ID label on the mower deck, rear housing area, or near the handle mounting points.
• Record the full model number (247377441) and the serial number exactly as shown.
• If the label includes a date code, write it down as well.
• Compare the label information to the identification section in the manual.
• Use the serial number when ordering parts to avoid mismatches.

Why the “riding mower year” answer does not apply here

Model numbers in the 247.xxxxxx range are used across multiple Craftsman and MTD-built products. 247377441 specifically maps to a 21-inch walk-behind mower platform, so riding mower timelines (like LT-series tractors) are not a reliable match.

Item	247377441 (this model)	Typical riding mower
Mower type	Walk-behind	Riding/tractor
Deck size	21-inch class	Often 42-inch and up
Starting method	Recoil starter; some versions may have electric start	Key start is common

Why it matters

Getting the year right helps us match the correct blade adapter, drive belt, wheels, and control cables for your exact configuration; small revisions can change fit even when the mower looks the same.

On Craftsman walk-behind mowers like model 247377441, the model number is typically printed on a product ID label on the mower deck (near the rear discharge area) or on the rear/side of the deck housing. Confirm the exact label location and format in the 247377441 owner's manual.

Where to look on the mower

Check these common spots first (wipe off grass and dirt so the label is readable):

• Top of the mower deck, near the rear discharge opening or rear skirt
• Rear of the deck housing, behind the bagger area
• Side of the deck housing, near a wheel height adjuster
• Handle mounting area where the lower handle bolts to the deck
• Under the deck lip (you may need a flashlight)

What the model number looks like

For this mower, the model number is a 247.xxxxx style number. Your label may show dots (for example, 247.377441) or no dots (247377441). Both identify the same model family.

Label item	What it’s used for	Example for this mower
Model number	Finding correct parts diagrams and manuals	247377441 (or 247.377441)
Serial number	Identifying production run details	Varies by unit

Tips if the label is missing or unreadable

• Look for an embossed/printed number on the deck near the label area
• Check for a second sticker near the handle brackets
• If your mower has electric start, check the battery/charger labels for their own model numbers (these are separate from the mower model)

Why it matters

Using the exact model number helps us match the right Craftsman parts (like a grass bag, wheel, belt, or drive control cable) to your mower’s deck and drive system so fit and performance stay correct.
