How do I know what model Craftsman mower I have?
For a Craftsman walk-behind mower, the model number is printed on the mower’s ID label, typically on the deck housing or frame. For your mower, the correct model format looks like 917.370620 (also shown as 917370620 on parts listings); match that number exactly when ordering parts.
Where to find the model number on a walk-behind mower
Check these common spots first (wipe off grass and dirt so the label is readable):
- Top of the mower deck near the engine
- Rear of the deck near the bagging or discharge area
- Side of the deck by a rear wheel height adjuster
- Handle support brackets or frame rails
- Under the rear door area (near the discharge chute door)
If the label is missing, the illustrated parts list in the 917370620 owner's manual can help you confirm you have the right mower family and assemblies.
What to write down (so parts match the first time)
Record the information exactly as shown on the label.
- Model number (example: 917.370620)
- Product number (if listed)
- Engine brand and series (this mower uses a Briggs & Stratton 675 Series engine)
- Any revision letters or additional digits on the tag
Quick check: model number vs. part numbers
| Item | What it identifies | Example on this mower |
|---|---|---|
| Model number | The mower itself | 917370620 |
| Part ID | Sears PartsDirect identifier for ordering | 532420463 |
| Part number | Manufacturer number printed in diagrams | 420463 |
Example: if you need a blade for this mower, the parts listing may show the lawn mower 22-in deck 3-in-1 blade 532420463.
Why it matters
Craftsman model numbers control fit and compatibility for key items like the blade, drive control cable, wheels, and transmission. One digit off can mean the wrong deck parts, wrong belt routing, or mismatched handle controls.

What model number is the Craftsman 42 riding mower?
The Craftsman model 917.370620 is a 22-inch walk-behind rotary lawn mower, not a 42-inch riding mower. For this Sears PartsDirect page, the correct model number is 917370620; you can confirm the model/serial decal location and specs in the 917370620 owner's manual.
How to identify your Craftsman mower model number
We recommend matching the model number on the mower’s decal to the format used on parts diagrams.
- Look for a decal on the rear of the mower housing (common location for this model)
- Record both the model number and serial number
- Match the number exactly, including any dots or dashes on the decal
- Use the model number to pull the correct parts list for your exact configuration
Walk-behind vs. riding mower: quick comparison
If you are shopping for parts, these identifiers help prevent ordering the wrong blade, cable, or wheel.
| Feature | Walk-behind mower (this page) | 42-inch riding mower |
|---|---|---|
| Typical deck size | 21 to 22 inches | 42 inches |
| Operator position | Walking behind | Sitting on tractor |
| Common drive type | Self-propelled belt/gearcase | Transaxle with drive belt |
| Typical parts you’ll see | Blade, drive cable, wheels | Deck belts, spindles, steering parts |
Parts clues that confirm this is a walk-behind mower
The 917370620 documentation and diagrams list walk-behind components such as a 22-inch blade and control cables.
- Lawn mower 22-in deck 3-in-1 blade 532420463 (walk-behind blade size)
- Drive control cable and drive pulley style components
- Rear door, grass bag frame, and clipping deflector parts typical of a push mower
Why it matters
A 42-inch riding mower uses a completely different deck, belt routing, and spindle system than a 22-inch walk-behind mower. Using the correct model number (917370620) ensures the right Craftsman parts fit and install correctly.

What year is Craftsman Model 917370620?
Craftsman model 917370620 is a model number, not a date code; it does not directly tell the year. To find the year, we use the mower’s product identification label (often on the deck or rear housing) and match its date or serial information using the owner's manual.
How to find the year on your 917370620 mower
Use these quick checks on the mower itself:
- Look for a product ID label on the mower deck, rear skirt area, or near the handle mounting points.
- Record the serial number and any date code printed on that label.
- Check the engine label (Briggs & Stratton) for an engine model/type/code; the engine code often includes a build date.
- Compare what you find to the identification and service info in the 917370620 owner's manual.
- If the label is missing or unreadable, use the mower’s parts configuration (handle style, drive system, deck components) to narrow it down.
What information to write down (so you get the right answer fast)
Capture these items before you start ordering parts or looking up specs:
- Mower model number: 917370620
- Serial number (from the mower ID label)
- Engine brand and numbers (Briggs & Stratton model/type/code)
- Deck size (this model is a 22-inch multi-cut deck per the manual)
- Whether it is power-propelled (this model is power-propelled)
Common “number confusion” to avoid
Model numbers, part numbers, and date codes look similar but mean different things.
| What you’re looking at | Example from this mower | What it tells you |
|---|---|---|
| Model number | 917370620 | Identifies the mower design and parts list |
| Part ID / part number | 532420463 / 420463 | Identifies a specific replacement part |
| Serial/date code | On the ID label | Often the best clue to the build year |
Why it matters
The build year affects small but important fit details, especially on drive and handle components. For example, the correct blade and hardware must match the deck and adapter setup; using the wrong blade can cause poor cut quality and vibration. If you are replacing the blade, the lawn mower 22-in deck 3-in-1 blade 532420463 is the model-matched blade listed for 917370620.
