How to read a Craftsman serial number?
On the Craftsman walk-behind mower model 917385391, the serial number is used mainly to identify your exact production unit for parts and service; you will find it on a decal on the rear of the mower housing. Record the serial number and purchase date together so you can match the correct diagrams and replacement parts.
Where to find the serial number on model 917385391
We look for the model and serial decal on the rear of the lawn mower housing (back of the deck). The location is shown and described in the 917385391 owner's manual.
- Shut the engine off and let the muffler and engine cool completely
- Tip the handle back and look at the rear of the deck (do not tip the mower with fuel in a way that can spill)
- Wipe grass and dirt off the decal so every character is readable
- Write the serial number exactly as shown (include any letters)
- Record the date of purchase in the manual’s space for it
How to interpret the serial number
Craftsman serial-number formats vary by product line and manufacturer, so we use the serial number primarily as an identifier, not as a guaranteed date code. For model 917385391, the most reliable approach is:
- Use the serial number to confirm you are ordering parts for the correct unit
- Use the model number (917385391) to pull the correct parts diagrams
- Use the purchase date for warranty and maintenance tracking
Quick guide: what to do with the number
| What you need | What to use | Why |
|---|---|---|
| Correct parts lookup | Model number 917385391 | Parts lists are organized by model |
| Unit identification | Serial number from the rear decal | Distinguishes your exact mower |
| Service history | Purchase date + serial number | Helps track maintenance and ownership |
Why it matters
A single digit off in a serial number can slow down parts matching, especially for wear items like the blade, blade adapter, and control cable. Keeping the serial number and purchase date together helps us get you the right Craftsman walk-behind mower parts the first time.

Is it cheaper to repair or replace a lawn mower?
For a Craftsman walk-behind mower model 917385391, it’s cheaper to repair when the issue is routine maintenance or a small wear part; replacement makes more sense when the engine or drive system needs major work or the mower has repeated failures. Use the 917385391 owner's manual to match the problem to the correct maintenance or adjustment.
Quick rule of thumb (repair vs replace)
- Repair when the mower still starts reliably and needs normal upkeep (blade, tune-up items, adjustments).
- Replace when a major component failure costs about half or more of the price of a comparable new mower.
- Replace when the mower has frequent breakdowns that keep adding cost and downtime.
- Repair when the deck, handle, and wheels are solid and you can restore performance with basic service.
- Replace when the mower is unsafe to operate (for example, persistent vibration after blade and adapter checks).
Costs that usually stay in the “repair” lane
Many common fixes are inexpensive because they involve wear items the manual treats as normal maintenance (blade, blade adapter, air filter, spark plug). These are also the repairs most likely to restore cut quality and reduce vibration.
Common examples for this model:
- Replace a worn or bent blade with the lawn mower blade 532406713
- Replace a damaged blade hub with the blade adapter 532418373
- Replace a stretched or damaged safety cable with the lawn mower engine zone control cable 582991501
When replacement is usually the better value
Major repairs tend to be less cost-effective because they can involve labor-intensive teardown and multiple parts.
Typical “replace” triggers:
- Engine compression problems, heavy smoking, or persistent no-start after ignition and fuel checks
- Self-propel or drive system failure that requires multiple drivetrain parts
- Structural damage (cracked deck, bent crankshaft symptoms such as severe wobble)
Comparison table
| Situation | Usually cheaper choice | Why |
|---|---|---|
| Dull blade, poor cut | Repair | Fast, low parts cost, restores performance |
| Excess vibration after impact | Repair first | Often blade or adapter related |
| Repeated major failures | Replace | Costs stack up quickly |
| Major engine or drive repair | Replace | High parts and labor relative to mower value |
Why it matters
Repairing early (especially blade care and annual tune-up items) protects the engine and improves cut quality. The manual also notes that warranty coverage depends on maintaining the mower as instructed, and that normal wear items are not covered.

What Craftsman lawnmower do I have?
You have a Craftsman walk-behind rotary lawn mower, model 917385391. On this mower, the model number is shown on the product identification label; once you match that number, you can use the correct parts list and diagrams from the 917385391 owner's manual.
Where to find the model number on your mower
Check these common spots first (clean off grass and dirt so the label is readable):
- On the mower deck housing (often near the rear or side of the deck)

What years did they make the Craftsman 917385391?
Craftsman model 917.385391 is a specific rotary walk-behind mower model number, and the most reliable way to pin down its exact production year is to match the model and serial information on the mower to the identification guidance in the 917385391 owner's manual. The manual confirms the model number and configuration (4.75 HP, 22-inch side discharge), but it does not list a single “made from year X to year Y” range.
How to identify the year for model 917385391
Use these checks to narrow the build date quickly:
- Locate the model and serial label on the mower (commonly on the rear of the deck, near the height adjusters, or on the handle support area).
- Confirm the label shows 917.385391 (sometimes printed with a dot as 917.385391).
- Write down the serial number exactly as shown.
- Compare the mower’s configuration to the manual (22-inch deck, side discharge, rotary design).
- Use the serial number to determine the manufacturing date through Craftsman or a servicing dealer.
Why the exact year range is not printed in the manual
For many Craftsman walk-behind mowers, the owner’s manual focuses on operation, maintenance, and parts breakdowns, while the serial number is what ties your unit to a specific production run.
What the manual does confirm
| Item | What we can confirm for 917385391 |
|---|---|
| Product type | Craftsman rotary walk-behind lawn mower |
| Cutting width | 22-inch deck |
| Discharge type | Side discharge |
| Engine rating shown | 4.75 horsepower |
Why it matters
Getting the correct year (or production run) helps you order the right replacement parts and avoid fit issues, especially for wear items like the blade and blade mounting hardware.
If you are replacing common wear parts, match by model number first, then verify by the illustrated parts list in the manual. For example, the lawn mower blade 532406713 and blade adapter 532418373 are model-matched parts that often depend on the exact deck and crankshaft setup.
