Craftsman 247378330 lawn mower Parts

Gas walk-behind mowers like the Craftsman 247378330 are not disappearing overnight, but new gas mower sales are gradually shifting toward battery-electric in many areas due to emissions rules, retailer assortment changes, and customer preference for quieter, lower-maintenance equipment. Parts and service support typically continue for years.

What “phased out” usually means for owners

Even when a market shifts, it rarely means you must stop using your mower. For most homeowners, the practical impact is about new product availability, not immediate restrictions on existing equipment.

• You can usually keep operating and maintaining a working gas mower.
• Replacement parts remain important because many owners keep gas mowers running long-term.
• Some regions may restrict new sales of certain gas-powered outdoor equipment.
• Electric options are growing because they are quieter and require less routine engine maintenance.
• Commercial and heavy-duty use cases often keep gas equipment in service longer.

How to keep a gas mower reliable as the market changes

The best way to “future-proof” a gas mower is consistent maintenance and using correct replacement parts.

• Follow the safety and maintenance schedule in the 247378330 owner’s manual.
• Keep fasteners tight and check adjustments at least once per season.
• For storage, run the engine until it stops from lack of fuel or use stabilizer in fresh fuel.
• Stop the engine, let it cool, and disconnect the spark plug wire before maintenance.
• If the mower will not self-propel, inspect the drive system; the ground drive belt is a common wear item.

Common wear items vs. longer-life assemblies

Item type	Examples on this model	Typical replacement frequency
Wear items	Drive belt, wheels, springs	As needed (wear, cracking, slipping)
Structural/assemblies	Deck housing, transmission assembly	Less often (damage, severe wear)

If your mower is not moving under power, the lawn mower ground drive belt, 3/8 x 31-1/4-in 954-04282 is one of the first parts we check for wear or stretching.

Why it matters

If gas mowers become less common in stores, maintenance and correct parts selection become the easiest way to extend the life of a mower you already own, avoid downtime mid-season, and keep cutting performance consistent.

On a Craftsman walk-behind mower like model 247378330, the model number is typically printed on the mower’s identification label on the rear of the deck, near the lower handle mounting points. Use that exact number when ordering parts or checking specifications in the 247378330 operator’s manual.

Where to look on the mower

Check these common label locations first:

• Back of the cutting deck (most common), between the lower handle mounts
• Rear skirt area (behind the deck, near the discharge opening)
• Side of the deck near the rear wheel height adjuster
• Under the rear flap or near the grass bag opening (if equipped)

What the label usually shows

The ID label often includes multiple numbers. Use this quick guide:

Label item	What it’s used for	Example format
Model number	Parts lookup and manual match	247.37833X or 247378330
Serial number	Manufacturing ID and service reference	Letters and numbers
Date code (if shown)	Build date reference	Varies

Tips to make sure you capture the right number

• Write the model number exactly as printed (include dots or suffix digits if shown).
• If the label is dirty, wipe it with a damp rag; avoid scraping off the print.
• If the last digit varies on your label, match the full model number on the sticker to the manual’s model list.

Why it matters

Craftsman walk-behind mowers often share the same deck size and controls across similar models, but parts like the drive belt, wheels, and deck components can differ by model suffix. Using the correct model number helps ensure the right fit the first time.

The model number is 247.37833* (commonly written without the dot as 247378330) for this Craftsman walk-behind mower. In the operator’s manual, 247.37833* is listed as a supported model series where the last digit can vary.

How the model number is shown on the mower

You may see the same model written a few different ways on the ID label and in documentation:

• 247378330 (no dot, full number)
• 247.37833* (manual format; the asterisk indicates the last digit varies)
• A longer product identifier may also appear on retail listings, but the service model we use for parts is 247378330

Where to confirm it on your unit

Check the mower’s model/serial label (typically on the rear of the deck housing or near the handle mounting area). Match the model exactly before ordering parts like a drive belt, wheel, or deck housing.

• Look for MODEL and SERIAL fields
• Record the full model number (including any suffix)
• Use the model number when selecting parts such as the ground drive belt or transmission

Quick reference

What you’re checking	What to look for	Why it matters
Model number	247378330 (or 247.37833*)	Ensures correct parts diagrams and fit
Serial number	Unique to your mower	Helps identify production variations
Deck size listing	Often “21 in.”	Helps match blades and deck components

Why it matters

Craftsman 247-prefix walk-behind mowers often share similar frames, but small model-number differences can change the correct blade adapter, belt length, or discharge components. Using the exact model number prevents ordering the wrong part.

For model-series confirmation and operating details, use the 247378330 owner’s manual.
