Craftsman 917370603 lawn mower Parts

Common problems on a Craftsman walk-behind mower like model 917370603 usually come down to starting issues, poor cutting, and self-propel drive problems. Most fixes involve basic maintenance (fuel, spark, blade condition) and checking wear parts such as cables, wheels, and the blade.

Most common symptoms and what they usually mean

• Won’t start or starts then dies: stale fuel, dirty carburetor, fouled spark plug, or a safety control issue
• Hard to pull the starter rope: blade obstruction, seized blade adapter area, or engine internal resistance
• Cuts unevenly or leaves clumps: dull/bent blade, deck packed with wet grass, incorrect mowing height
• Vibrates excessively: bent blade, loose blade hardware, debris wrapped around the blade area
• Self-propel won’t move or slips: stretched/misadjusted drive cable, worn transmission/drive components

Quick checks we recommend first (fast and safe)

1. Shut the mower off and disconnect the spark plug wire.
2. Tip the mower only as directed in the 917370603 owner's manual to avoid fuel or oil issues.
3. Inspect the blade for damage and tightness.
4. Check the control cables for smooth movement and proper tension.
5. Clean packed grass from the underside of the deck.

The model number is 917370603. On Craftsman walk-behind mowers, the model number is the key identifier we use to match the correct parts list, diagrams, and repair instructions for your exact mower.

Where to find the model number on the mower

Look for a model and serial number label on the mower body. Common locations include:

• On the rear of the deck near the discharge opening
• On the top of the deck near the engine mounting area
• Near the rear wheel height adjuster area
• On the handle support or rear frame area

If the label is dirty or faded, wipe it with a damp rag and read it in bright light.

What to record (so parts match the first time)

Write down these details exactly as shown on the label:

• Model number: 917370603
• Serial number (helps confirm production run)
• Engine model and type (engine parts are often separate from mower chassis parts)
• Any suffixes or additional numbers on the tag

Model number vs. other numbers you may see

It is normal to find multiple numbers on a mower. Here is how to tell them apart:

Number you see	What it usually identifies	Used for
917370603	Mower chassis model	Deck, wheels, drive system, controls
Engine model/type code	Engine family	Spark plug, air filter, carburetor parts
Part numbers (stamped on parts)	Individual component	Replacing that specific component

Why it matters

Using 917370603 ensures we match the correct Craftsman walk-behind mower parts (like the blade, drive cable, or transmission) and avoid ordering a similar-looking part that will not fit.

For model-specific identification details and label location guidance, use the 917370603 owner's manual.

On your Craftsman walk-behind mower, the model number is printed on the mower’s model-and-serial tag (a sticker or metal plate) mounted on the mower deck or rear housing. For this parts page, the model number you’re looking for is 917370603.

Common places to check on model 917370603

Look for a label that includes both a model and serial number. Typical locations include:

• On top of the mower deck near the engine (often close to the recoil starter area)
• On the rear of the deck near the discharge opening or rear door
• On the side of the deck near a rear wheel height adjuster
• Under the handle mounting area where the handle brackets attach
• Near the bagging or mulching opening (rear or side, depending on setup)

What the tag looks like and what to write down

The tag is usually a rectangular sticker/plate with several lines of numbers.

• Write down the full model number exactly as shown (for example, 917370603)
• Record the serial number too; it helps match production changes
• If the label is dirty, wipe it with a damp rag and mild soap, then dry it
• If the label is faded, use a flashlight at an angle to make the print easier to read

Why the model number matters

We use the mower model number to match the correct chassis parts (deck, wheels, cables, handle hardware) so you get the right fit the first time. For example, blade and control-cable designs can vary by model.

If you need parts for	Use this number	Example part that depends on it
Mower deck, wheels, handle, drive system	917370603	Lawn mower drive control cable 588479201
Engine-specific parts (carburetor, ignition, recoil)	Engine model/type code on the engine	Spark plug, air filter, carburetor kit

Where to confirm the correct number

If you find multiple numbers on the tag, use the one labeled Model (not a patent number or deck size). For diagrams and identification tips, use the 917370603 owner's manual.
