What size deck is a Craftsman 917386130?
The Craftsman rotary lawn mower model 917386130 uses a 20-inch cutting deck; you’ll typically match blades and deck-related hardware by that 20-inch size when ordering replacement parts.
How to confirm the deck size on your mower
We recommend verifying the deck size using the blade length and the deck shell measurement.
- Remove the spark plug wire before working near the blade.
- Tip the mower with the air filter and carburetor facing up.
- Measure the blade end-to-end; this model commonly uses a 20-inch blade.
- Measure the deck opening side-to-side at the widest point.
- Compare what you measure to the replacement blade listing.
A common replacement blade for this model is the husqvarna lawn mower 20-in deck blade 532145106.
Parts that commonly match the deck size
Deck size affects which blade, blade adapter, and fasteners fit correctly.
| Deck-related item | What it does | Example part for model 917386130 |
|---|---|---|
| Blade | Cuts grass; length matches deck | Husqvarna lawn mower 20-in deck blade 532145106 |
| Blade adapter | Connects blade to engine shaft | Lawn mower blade adapter 581547901 |
| Lock nut | Helps secure blade/adapter hardware | Lock nut 532409149 |
Why it matters
Using the correct deck size prevents poor cutting, vibration, and stripped hardware. A blade that is too long can strike the deck; a blade that is too short can leave uncut strips.

What model number is the Craftsman 917386130?
The model number is 917386130. On Craftsman rotary lawn mowers, the model number is the primary identifier we use to match the correct parts list and diagrams for your exact mower.
Where to find the model number on your mower
Look for a model tag or sticker on the mower and match it exactly to 917386130.
- Check the rear of the deck near the discharge opening
- Check the top of the deck near the engine mounting area
- Check the handle support brackets or rear frame area
- Wipe off grass and oil film; the tag is often hard to read when dirty
- Write the number down exactly as shown (all digits, no spaces)
Why your model number matters for parts
Using the correct model number helps ensure the blade, blade adapter, and hardware fit your Craftsman mower’s deck and crankshaft correctly.
Here are examples of model-matched parts you can use as reference points when shopping:

Why it matters
A single digit difference can change deck size, blade mount style, or hardware thread type; that can lead to poor cutting, vibration, or stripped fasteners.

How to find Craftsman mower parts?
To find the right replacement parts for your Craftsman rotary lawn mower model 917386130, match the model number from the mower’s ID label to the parts list, then confirm each part by name and diagram location before ordering.
Where to find the model number on the mower
On most Craftsman walk-behind mowers, the model number is printed on an ID label attached to the mower deck or rear frame area. Wipe off grass and dirt first so the full number is readable.
Quick checklist
- Look on the rear frame between the wheels and around the deck housing
- Clean the area so you can read all digits clearly
- Use the full model number: 917386130 (not a partial)
- If the label is damaged, check for a stamped number on the deck or frame
How we recommend matching the correct part
Once you have the model number, use the parts list for model 917386130 and verify the part by both description and where it appears in the diagram.
Best practice steps
- Identify the system you are repairing (blade area, handle hardware, bagger, etc.)
- Compare the part name to what you see on the mower
- Confirm fastener size and thread type before ordering (nuts, bolts, washers)
- Replace worn blade-mounting hardware if it shows rounding, stretching, or rust
Common parts customers replace on this model
| Repair area | Example part on this page | What it helps with |
