Craftsman 247377001 lawn mower Parts

For Craftsman walk-behind mower model 247377001, we find the model number on the mower’s identification label; it’s typically on the back of the deck, between the lower handle mounts. Match that label to your parts list and 247377001 operator’s manual to ensure you order the correct parts.

Where to look on the mower

Check these common label locations first:

• Back of the mower deck, between the lower handle mounts (most common)
• Rear discharge area near the trail shield
• Side of the deck near a rear wheel or height adjuster
• Under the rear flap or near the bagging opening

What to write down (and why)

Record the full ID information exactly as shown on the label.

• Model number: identifies the exact mower configuration
• Serial number: helps confirm production run and correct part variations
• Engine model/type/code (on the engine itself): needed for engine-specific parts like spark plugs and air filters

Quick ID checklist

Item	Where it’s found	Why it matters
Mower model number	Mower deck label	Matches the correct Craftsman parts diagrams
Mower serial number	Mower deck label	Helps confirm correct revisions
Engine model/type/code	Engine shroud label	Matches engine tune-up and fuel system parts

Why it matters

Craftsman walk-behind mowers can look similar across multiple model numbers, but parts like the drive belt, control cables, wheels, and bagging components can differ. Using the exact model number prevents ordering the wrong replacement.

For the Craftsman lawn mower model 247377001, use fresh regular unleaded gasoline; premium high-octane fuel is not needed. For storage, we recommend adding fuel stabilizer to a full tank and running the engine briefly to circulate it (see the 247377001 owner's manual).

Fuel type and what to avoid

• Use fresh, clean regular unleaded gas from a busy station.
• Avoid stale gas (older than about 30 days without stabilizer).
• Avoid mixing in oil unless your engine specifically calls for it (most walk-behind mowers are 4-cycle).
• Avoid overfilling; leave a little expansion space in the tank.
• For long storage, either run it dry or treat the fuel with stabilizer.

Storage guidance (from the manual)

If the mower will sit for more than 30 days, the manual recommends preventing gum/varnish in the fuel system by doing one of the following:

Storage plan	What to do	Best for
Treat the fuel	Add gasoline additive (stabilizer) and run the engine a few minutes	Seasonal storage with fuel left in tank
Run it dry	Run the engine until it stops from lack of fuel	Short-term storage when you prefer an empty tank

Also follow the manual safety step before any maintenance: stop the engine, let it cool, and disconnect the spark plug wire.

Why it matters

Correct fuel and storage habits reduce carburetor clogging, hard starting, and rough running. Fresh gas plus stabilizer during off-season storage helps keep the fuel system clean and the mower ready for the next cut.

For the Craftsman 247377001 gas walk-behind mower, the published average useful life is 7 years or about 140 hours of operation. With consistent maintenance (oil service, blade care, and deck cleaning), many walk-behind mowers deliver reliable performance through that window and beyond.

What “lifespan” means for this mower

The manual defines an Average Useful Life as a time and hour benchmark, then recommends annual inspections after you reach it. See the 247377001 owner's manual.

Typical outcomes by usage pattern

• Light use (small yard, weekly mowing): often reaches the 7-year benchmark with fewer repairs
• Heavy use (large yard, long season, dusty conditions): reaches 140 hours sooner; maintenance matters more
• Poor maintenance (old fuel, dull blade, packed deck): shortened service life and more starting or cutting issues

Maintenance that most affects service life

We see these items make the biggest difference on walk-behind mowers like the Craftsman 247377001:

• Change engine oil on schedule (more often under heavy load or high heat)
• Keep the blade sharp and balanced; replace if bent or badly worn
• Clean the underside of the deck by scraping (avoid spraying with a hose or pressure washer)
• Check and tighten fasteners at least once each season
• Use fresh fuel and add stabilizer before storage

Quick reference: time vs. hours

Measure	What it tells you	For this mower
Years	Calendar age	7 years average useful life
Hours	Actual run time	140 hours average useful life
After that point	Safety and wear check	Inspect annually by a qualified service dealer

Why it matters

A mower can still run past its average useful life, but wear in safety and mechanical systems (blade control, fasteners, shields, drive components) increases the risk of breakdowns and poor cut quality. Staying on top of maintenance protects the engine, the deck, and the operator.
