• Near the handle mounting brackets (left or right side)
• On a sticker or plate that also lists the serial number

What to write down (and why)

Record both numbers before the label gets dirty or worn.

• Model number: identifies the exact mower version (needed for correct parts diagrams)
• Serial number: helps match production changes and correct replacement parts

Quick ID checklist

Item	What it does	Example for this mower
Model number	Matches parts lists and diagrams	917374543
Serial number	Helps confirm exact build	From the rear decal
Engine info	Helps with engine-specific parts	Briggs & Stratton 700 series

Why it matters

Using the correct model number prevents ordering the wrong blade, drive belt, or control cable. For example, this mower uses a 22-inch multi-cut deck; matching the model ensures the cutting system and drive components fit and operate safely.

For the Craftsman walk-behind mower model 917374543, use fresh regular unleaded gasoline; fuel with up to 10% ethanol (E10) is acceptable. Do not use gasoline with more than 10% ethanol because it can cause running problems and can void the warranty (per the manual). See the 917374543 owner's manual for the exact fuel guidance and safety notes.

Recommended fuel for model 917374543

• Regular unleaded gasoline (fresh, clean fuel)
• Up to E10 (10% ethanol) is OK
• Avoid fuel blends above E10
• Use clean, approved gas cans to prevent dirt and water contamination
• Do not store gasoline from one season to the next

Quick fuel do's and don'ts

Item	Use it?	Notes
Regular unleaded	Yes	Best everyday choice for small mower engines
E10 (10% ethanol)	Yes	Specifically noted as acceptable in the manual
E15, E20, E85	No	Ethanol above 10% is not recommended for this mower
Old/stale gas	No	Common cause of hard starting and poor performance

Why it matters

Using the right gasoline helps your 917374543 start easier, run smoother, and reduces fuel-system issues like varnish buildup, water contamination, and clogged carburetor passages. Fresh fuel also helps prevent “won’t start” symptoms tied to stale gas.

Helpful tips if the mower won’t start after fueling

If you filled the tank and it still will not start, these checks are the most common:

• Confirm the tank actually has fresh fuel (not last season’s)
• Check the air filter for heavy dirt buildup
• Make sure the spark plug wire is firmly connected
• Verify the operator presence control bar is held down while starting
• If fuel is old or contaminated, drain and refill with fresh gas

Your Craftsman walk-behind mower model 917374543 does not use a serial number that reliably encodes the exact build date. For the most accurate “age,” we use the date of purchase you recorded and the serial number location shown in the 917374543 owner's manual.

Where to find the serial number on model 917374543

The model and serial numbers are on a decal on the rear of the lawn mower housing.

• Tip the mower only as directed in the manual (to avoid oil or fuel issues)
• Wipe the rear housing clean so the decal is readable
• Record the full serial number exactly as shown
• Also record the purchase date (this is the best “age” reference)

How we determine “age” from the numbers you have

For this Craftsman mower, the most dependable way to describe age is based on purchase date and documentation, not decoding the serial number.

What you have	What it tells you	Best use
Date of purchase	When you started using the mower	Best for maintenance intervals and “how old” questions
Serial number (rear decal)	Identifies your specific unit	Best for parts lookup and service records
Engine model/type code (on engine)	Often includes an engine manufacture date	Helpful if you want an approximate engine build timeframe

If you still want an approximate manufacture timeframe

Use these practical checks (in order):

• Check your receipt, warranty paperwork, or maintenance log for the purchase date
• Look up the engine date code on the engine shroud or valve cover (engine makers often encode dates there)
• Compare wear items and service history (blade, belt, wheels) to typical replacement cycles
• Use the parts diagrams in the manual to confirm you are matching the correct configuration

Why it matters

Knowing the mower’s age helps us recommend the right maintenance schedule (oil type, spark plug, blade bolt torque) and helps you choose correct OEM replacement parts for safe operation.

On Craftsman walk-behind mowers like model 917374543, the serial number is typically used to identify the production run and help match the correct parts; the most reliable way to interpret it is to use the serial-number format shown in your 917374543 owner's manual.

Where to find the serial number

Most Craftsman walk-behind mowers place the model and serial information on a label or stamped plate. Check these common spots:

• Rear of the deck near the discharge opening
• Top of the deck behind the engine
• Near the rear wheel height adjuster area
• On the handle bracket area
• Under the grass bag or near the rear door

How to interpret the serial number (what to look for)

Craftsman serial formats vary by manufacturer and production year, so we recommend matching the pattern shown in the manual first. When you read the serial number, note:

• How many digits/letters it contains
• Whether it’s all numbers or letters plus numbers
• Any dashes or spaces that separate groups
• Any date-style grouping (for example, MMDDYY) if your label uses that format

Quick check table

What you see on the label	What it usually means	What to do next
“Model No. 917.374543”	The mower model identifier	Use it to select exact parts for the deck, drive, and controls
A separate “Serial” line	Production identifier	Compare its grouping to the format shown in the manual
Extra codes (engine tag)	Engine model/type/code	Use for engine-specific parts like spark plug or air filter

Why it matters

The serial number helps prevent ordering the wrong blade, belt, or control cable when there were mid-year changes. For example, model 917374543 uses a specific drive belt and drive system parts such as the lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527.

Tip for parts matching

When you record the information, write it exactly as shown:

• Model number (917374543)
• Serial number (full string)
• Engine identification from the Briggs and Stratton engine tag
