Are Craftsman and Husqvarna parts interchangeable?
Yes, many Craftsman and Husqvarna parts interchange on riding mower decks, especially on Craftsman models like 917253520 that commonly share AYP-style deck designs. The only reliable way to confirm fit is to match the exact part ID or manufacturer part number for your specific deck and revision.
How to confirm interchangeability (the method we use)
- Match the model number exactly: 917253520
- Compare the part ID and part number on the parts list
- Verify the part’s location and function (deck hardware vs. spindle vs. belt routing)
- Check for deck size and configuration differences (36-inch decks can still vary by hanger style)
- Replace deck hardware in sets when wear is uneven (nuts, washers, retainers)
Common parts that are often shared
On mower decks, the most commonly interchangeable items are basic hardware and wear items. For this model’s deck kit, examples include:
Quick fit-check table
| What you’re comparing | Good sign | Red flag |
|---|---|---|
| Part ID | Same ID on both lists | Different ID for same location |
| Part number | Same manufacturer number | Superseded to a different spec |
| Deck configuration | Same deck size and hanger layout | Different lift link or bracket style |
| Hardware | Same thread size and grade | Different thread pitch or flange style |
Why it matters
Deck parts that look identical can still differ in thread pitch, offset, or mounting geometry. Using the exact matched part ID helps prevent stripped threads, misalignment, uneven cutting, and premature belt or spindle wear.

What year did Craftsman make the 917253520?
Craftsman model 917253520 is a 917-series riding mower/tractor platform that was sold across multiple production years, so the model number alone does not map to one single year. We identify the exact build year by using the serial number/date code on the tractor’s ID tag.
How to find the exact year for 917253520
Look for the model and serial tag in one of these common locations:
- Under the seat pan (lift the seat)
- On the rear fender area near the seat
- On the frame rail near the engine
- Near the footrest area on the chassis
Once you find the serial number, use these steps:
- Write down the full serial number exactly as shown
- Look for a date code embedded in the serial number (many Craftsman/Husqvarna-built units use a date-coded format)
- If the tag shows a month and year directly, use that as the build date
- If the tag shows only a serial, use the date-coded portion to determine the year
Why the serial number matters (not just the model)
The 917 prefix identifies a manufacturing family used for many years, and the same model number can appear with running changes (deck hardware, belt routing, idlers, and fasteners). The build date helps us match the correct complete deck parts and hardware.
Quick reference: what you can confirm from the tag
| What you have | What it tells you | What it does not tell you |
|---|---|---|
| Model number (917253520) | Product family and configuration | Exact build year by itself |
| Serial number/date code | Build date (year) | Exact engine model/options |
| Deck sticker/label | Deck size and some specs | Tractor build year |
Parts you may replace while verifying deck details
If you are working on the 36 inch deck hardware while you confirm the build date, these common items are available for this model’s complete deck listing:
- Nut 596322601 (fastener used in multiple deck locations)
- Washer 819111416 (spacer/washer used with deck hardware)
- Spring retainer 532004921 (retains tension springs on linkages)
- Skid 583767801 (deck wear skid)
Why it matters
Ordering the right belt, spindle, or linkage hardware depends on the exact configuration used in your production run. Confirming the build year from the serial tag prevents mismatches and repeat repairs.

How to read Craftsman model number?
For Craftsman riding mower and deck parts, the model number (like 917253520) identifies the exact product family and parts breakdown; it is not a date code. Use the full model number to match the correct diagrams and replacement parts for your Craftsman 36" mower replacement kit.
What the model number tells you (and what it does not)
Craftsman model numbers are used for parts identification, not for decoding the build date.
- Model number (example: 917253520): used to look up the correct parts list and diagrams
- Product type/category: helps narrow to the right section (deck, drive, steering, etc.)
- Build date: typically found on a separate serial number or product ID label, not in the model number itself
Where to find the model number on the mower
On most Craftsman riding mowers and decks, the model/serial label is commonly located in one of these places:
- Under the seat on the frame
- On the rear frame plate near the hitch area
- On the underside edge of the hood or near the dash tower
- On the mower deck shell (often near a belt cover or discharge chute area)
