Craftsman 917370931 lawn mower Parts

To identify what kind of lawn mower you have, match the brand and model number on the mower’s ID label to the information in your documentation. For this Craftsman walk-behind mower, the model is 917370931; the Craftsman 917370931 owner's manual also confirms the model number.

Where to find the model information on the mower

Look for a sticker or metal tag on the mower; common locations include:

• Rear of the deck near the discharge opening
• Top of the deck near the engine mounting area
• Handle support brackets or the lower handle area
• Under the rear door (bagging opening) on rear-discharge models
• Near the wheel height adjuster area

What to write down (so you get the right parts)

For accurate parts lookup and diagrams, record these items:

• Mower model number (example: 917370931)
• Engine model and type code (engine has its own ID label)
• Serial number (helps confirm production run)
• Product type (walk-behind, self-propelled, rear discharge, etc.)

Why there are often two sets of diagrams

Most walk-behind mowers use:

Diagram type	Covers	Examples
Mower (chassis) diagrams	Deck, handle, wheels, drive system, discharge parts	blade, belt, wheels, deflector
Engine diagrams	Fuel/ignition and internal engine parts	carburetor, air filter, spark plug

Quick confirmation using a known model-specific part

If your mower matches Craftsman 917370931, you will see common mower components referenced in the manual, such as the discharge deflector and blade. A frequent replacement item is the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.

Why it matters

Using the exact mower model number and the engine ID prevents ordering the wrong blade, drive belt, or control cable, and it ensures the parts diagrams match your deck and drive configuration.

Common problems we see on the Craftsman 917370931 walk-behind mower include no-start conditions (stale fuel, dirty air filter, bad spark plug, or a loose/bent blade setup), loss of power from deck buildup, excessive vibration from a damaged blade or crankshaft, and drive issues from a worn belt or transmission parts. For model-specific troubleshooting steps, use the 917370931 owner's manual.

Most common symptoms and what usually causes them

• Won’t start: stale fuel, water in fuel, dirty air filter, spark plug wire off, bad spark plug, control bar not held down
• Loss of power: grass and debris packed under the deck, cutting too much grass at once, dirty air filter, oil level issues
• Poor cut (uneven): worn or bent blade, uneven wheel height settings, buildup under the mower housing
• Excessive vibration: loose blade hardware, bent blade, broken blade adapter, bent engine crankshaft
• Hard to push or loss of drive: worn drive belt, worn drive pawls, transaxle wear, belt guide issues

Quick checks we recommend before buying parts

1. Confirm the control bar is fully depressed to the handle during starting.
2. Drain and refill with fresh gasoline if fuel is older than about 30 days.
3. Inspect under the deck (engine off, spark plug wire disconnected) and remove packed grass.
4. Check the blade for damage and tightness; replace if bent or badly worn.
5. Look for drive belt wear (glazing, cracking, stretching) if the mower slows or won’t self-propel.

Parts that commonly fix these issues on model 917370931

Symptom	Part to inspect/replace	Example from this model’s parts
Poor cut, vibration	Blade	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Loss of drive, slowing	Ground drive belt	Lawn mower ground drive belt, 3/8 x 35-3/8-in 532421527
Won’t move (self-propel)	Transaxle	Lawn mower transaxle 581680801

Why it matters

These problems are more than convenience issues. A loose or damaged blade can cause strong vibration and additional damage, and heavy deck buildup can reduce airflow and cutting performance, making the engine work harder than it should.

Craftsman model 917.370931 is identified in the owner’s manual as a 22-inch, power-propelled rotary mower with a Briggs & Stratton 725 Series engine and electric start; the manual itself does not list a specific first and last production year. For the exact build year, we use the mower’s product ID/serial information shown in the 917370931 owner’s manual.

How to find the exact year for model 917370931

We match the mower’s identification numbers to the manufacturing date range.

• Write down the serial number exactly as shown (letters and numbers)
• If your mower has electric start, also note any battery or starter labeling
• Compare the identification info to the model identification section in the manual
• Use the parts list diagrams to confirm you are working with 917.370931 (not a close variant)

The manual confirms the configuration and key features for 917.370931, which helps ensure you are dating the correct mower.

Why it matters

On your Craftsman walk-behind mower, the model number is printed on the mower’s identification label; for this unit it appears as 917.370931 in the documentation. Use that mower model number (not the engine numbers) when ordering non-engine parts for model 917370931.

Common places to check on a walk-behind mower

Look for a sticker or metal tag in these spots:

• On the rear of the mower deck (behind the engine)
• On the top of the deck near the engine mounting area
• Near the rear discharge door or bagging opening
• On the handle bracket area (left or right side)
• Under the deck lip near the wheel height adjuster

If the label is dirty or faded, wipe it with a damp rag and mild soap; avoid scraping so you do not remove the printing.

What number to use (and what to ignore)

Use the mower model number for most parts like blades, belts, wheels, and cables. Engine labels often show separate numbers that do not match the mower parts list.

You’re looking at	What it’s used for	Example on this mower
Mower model number	Ordering mower chassis parts	917.370931 (model 917370931)
Engine model/type/code	Engine-specific parts and service	Briggs & Stratton engine numbers

Why it matters

The model number ties directly to the correct illustrated parts list and hardware sizes. Using the wrong number can lead to ordering a blade, drive belt, or control cable that does not fit.
