Craftsman 247397900 28" lawn mower - pro series Parts

For a Craftsman walk-behind mower like model 247397900, the model number is typically printed on an ID label or decal on the mower deck housing or rear frame area. Once you confirm the model number, we can match the correct parts and diagrams for your exact mower.

Where to look on model 247397900

Check these common label locations first:

• On top of the mower deck near the engine mounting area
• On the rear of the deck, near the discharge chute opening
• On the back of the mower frame between the rear wheels
• Near the height-adjustment brackets on the deck side
• On a label panel near the handle mounting points

If the label is dirty or faded, wipe it with a damp rag and mild soap, then re-check under good lighting.

What the label usually shows

Most Craftsman mower ID labels include a few fields. Use the model number to look up parts.

Label field	What it’s used for	Example (format)
Model number	Primary identifier for parts lookup	247397900
Serial number	Production tracking, sometimes needed	Varies
Date code	Manufacturing reference	Varies

For model-specific diagrams and identification notes, use the 247397900 manual.

Why it matters

Craftsman walk-behind mowers often share similar deck sizes and engines across multiple models, but small differences (blade adapter style, wheel hardware, bearings, decals) can change the correct replacement part. Using the exact model number helps avoid ordering the wrong component.

If your ID label is missing or unreadable, you can sometimes confirm you are working with the correct unit by comparing remaining decals and markings, such as the Craftsman label 777I25461.

For a Craftsman model 247397900 walk-behind mower, it’s usually cheaper to repair when the fix is routine maintenance or a single worn part and the total cost stays under about half the price of a comparable new mower. Replacement makes more sense when major drivetrain or engine problems keep recurring.

A practical cost rule we use

A simple way to decide is to compare the total repair cost (parts + labor + your time) to the cost of a similar new mower.

• Repair when the total is under ~50% of a comparable new mower
• Replace when the total is over ~50%, especially if multiple issues stack up
• Repair when the mower is otherwise solid and needs only one clear fix
• Replace when performance is declining and repairs are becoming frequent
• Repair when the problem is maintenance-related (blade, belt, tune-up items)

For model-specific maintenance intervals and safety steps, follow the 247397900 owner’s manual.

Repair vs. replace: quick comparison

Situation	Usually best choice	Why
One obvious wear item (fastener, bearing, belt, blade)	Repair	Low parts cost, quick turnaround
Deck and controls are solid, starts reliably	Repair	You keep a known-good machine
Repeated no-start, smoking, low compression, or major drive issues	Replace	High labor and uncertain long-term reliability
Multiple systems failing at once	Replace	Costs add up quickly

Examples of “repair-friendly” fixes on this model

If the mower is otherwise in good shape, these are the types of repairs that often stay cost-effective:

• Replacing a worn fastener such as lawn & garden equipment hex nut 41657
• Servicing a rotating component that uses a bearing such as mtd lawn & garden equipment ball bearing 741P0919B
• Basic tune-up work (oil change, spark plug, air filter, blade sharpening)

Why it matters

A mower that’s repaired at the right time typically delivers the lowest cost per season. Replacing too early wastes value; repairing too late can mean repeated downtime and compounding repair bills.

The most common repairs on a Craftsman 247397900 gas walk-behind mower are fuel-related no-start issues, poor cutting from a worn or damaged blade system, and drive or wheel problems that affect self-propelled movement. We start with basic maintenance checks, then inspect wear parts and fasteners.

Most common problems (and what to check first)

• Won’t start or starts then dies: old fuel, clogged fuel path, dirty air filter, fouled spark plug
• Runs rough or surges: restricted airflow, stale fuel, carburetor varnish, loose fasteners
• Cuts uneven or leaves strips: dull/bent blade, deck buildup, worn bearings, incorrect cutting height
• Vibration or rattling: loose blade hardware, damaged blade, loose engine mounting hardware
• Poor drive or hard to push: worn wheel/drive components, seized or worn bearings

Quick DIY checks we recommend (safe, high-impact)

1. Use fresh gasoline; if fuel is older than about 30 days, drain and refill.
2. Inspect and clean the air filter area; replace the filter if it’s oil-soaked or packed with debris.
3. Check the spark plug condition and gap; replace if fouled.
4. Clean grass buildup under the deck (with the spark plug wire disconnected).
5. Tighten visible hardware on the handle, deck, and wheels.

Parts that commonly come up on this model

Some repairs are simply tightening or replacing worn hardware and rotating components. These model-compatible examples are common in mower service:

Symptom	Likely area	Example model-compatible part
Rattle, loose handle/deck hardware	Fasteners	Lawn & garden equipment hex nut 41657
Rough wheel movement, squeal, wobble	Wheel/deck bearings	Mtd lawn & garden equipment ball bearing 741P0919B

Why it matters

Catching fuel and airflow issues early prevents hard starting and stalling; addressing blade, bearing, and fastener wear helps protect the crankshaft, improves cut quality, and reduces vibration.

For model-specific maintenance intervals, adjustment points, and safety steps, use the 247397900 manual.

For the Craftsman 247397900 walk-behind mower, the exact build year usually comes from the date code embedded in the serial number on the product ID label. The specific serial-number format can vary by production run, so we use the model’s labeling guidance in the 247397900 owner’s manual to confirm where to find it and how to interpret it.

Where to find the serial number on a walk-behind mower

Most Craftsman walk-behind mowers place the model and serial information on a sticker or stamped tag. Common locations include:

• Rear of the deck (near the discharge chute area)
• Top of the deck, behind the engine
• On the handle support or rear frame area
• Near the height-adjuster bracket

How Craftsman serial date codes are commonly formatted

On many Craftsman and MTD-built products, the serial number may include a date code segment that represents a manufacturing date. A common pattern you may see is:

• MM = month
• DD = day
• YY = year

Example (how to read it)

Date code segment	Meaning	Example result
07 28 11	Month Day Year	July 28, 2011

If your serial number does not match this pattern, that does not mean it is wrong; it just means your 247397900 may use a different coding scheme.

Why it matters

Knowing the build year helps us match the correct parts list and diagrams for your Craftsman 247397900, especially for items that can change mid-production (labels, bearings, and hardware).

Parts tip when the label is damaged

If the ID label is missing or unreadable, replacing a missing decal can help keep the mower identifiable.

• Check the Craftsman label 777I25461 if your Craftsman branding label is worn
• If you need other identification decals, compare the label style and placement before ordering
• Keep a photo of the model and serial tag for future parts lookups
