How to read Craftsman serial number?
On Craftsman walk-behind mower model 917388964, the serial number is primarily used to identify the exact production run for parts and service; you’ll find it on a decal on the rear of the mower housing. For the correct location and recording details, use the 917388964 owner's manual.
Where to find the serial number on model 917388964
The manual specifies the model and serial numbers are on a decal on the rear of the lawn mower housing. Once you locate it, record the serial number and your purchase date for future parts lookups.
- Look at the back of the mower deck (rear housing area)
- Clean off grass and dirt so the decal is readable
- Write down the full serial number exactly as shown
- Record the date of purchase next to it
- Keep the information with your maintenance records
How Craftsman serial numbers are commonly formatted
Many Craftsman outdoor power products use a date-style serial format where groups of digits represent a build date. A common pattern is:
| Digits in serial number | Often represent | Example meaning |
|---|---|---|
| 1st–2nd | Month | 07 = July |
| 3rd–4th | Day | 28 = 28th |
| 5th–6th | Year | 11 = 2011 |
Use this as a quick read, then confirm by matching the mower’s exact model identification and parts list in the manual.
Why it matters
Reading the serial number correctly helps us match the right Craftsman parts (blade, blade adapter, zone control cable, wheels, and handle hardware) to your exact mower configuration, especially when a model has multiple production variations.

What model number is the Craftsman 917388964?
The model number for this Craftsman walk-behind rotary lawn mower is 917.388964 (often written without the dot as 917388964). You can confirm it on the model tag and in the Craftsman 917388964 owner's manual.
Where to find the model number on the mower
Look for the model label in one of these common spots:
- On the rear of the mower deck near the discharge opening
- On the top of the deck near the engine mounting area
- Near the handle mounting brackets
- In the documentation that came with the mower
Why you might see it written two ways
Both formats refer to the same mower; the dot is just a formatting difference.
| Format you see | What it means | Use it for |
|---|---|---|
| 917.388964 | Official manual/model tag format | Manuals, parts diagrams, service references |
| 917388964 | No-dot format | Online parts lookup and ordering |
Why it matters
Using the exact model number helps us match the correct Craftsman parts (like the blade, blade adapter, or zone control cable) and avoid ordering hardware that looks similar but fits differently.

How old is my mower by serial number?
Your Craftsman walk-behind mower model 917388964 uses the serial number mainly for identification and warranty records; the build date is typically decoded by the engine manufacturer (often Briggs & Stratton) or by Craftsman production coding. Start by finding the model and serial decal on the rear of the mower housing, then use the manual’s guidance to record the details.
Where to find the serial number on model 917388964
The model and serial numbers are on a decal on the rear of the lawn mower housing. Use the 917388964 owner's manual to confirm the decal location and the exact fields to record.
- Look on the rear of the deck housing (not the handle tube)
- Clean the area so the decal text is readable
- Write down the model number and serial number exactly as shown
- Record the date of purchase if you still have it (receipt, email, or warranty card)
- Take a clear photo of the decal for reference
How to estimate the mower’s age using the serial number
For many walk-behind mowers, the most reliable “age” clue comes from the engine model and code, not the mower deck serial. The manual for this mower lists a Briggs & Stratton engine model (commonly shown on the engine shroud label).
- Find the engine label (usually on the blower housing near the pull starter)
- Record the engine model/type/code exactly
- Use the engine “code” to determine the manufacturing date (Briggs & Stratton commonly encodes date information there)
- Compare that engine build date to your purchase date to estimate the mower’s service age
Quick comparison: mower serial vs. engine code
| Identifier | Where you find it | What it’s best for |
|---|---|---|
| Mower serial number | Rear of mower housing decal | Registration, parts lookup, warranty records |
| Engine model/code | Engine shroud label | Determining approximate manufacturing date |
Why it matters
Knowing the approximate age helps us match the right replacement parts (blade, blade adapter, zone control cable, wheels) and plan maintenance intervals like blade sharpening, oil changes, and tune-ups.
If you are servicing cutting components while you check labels, match parts by model number and diagram; for example, the husqvarna lawn mower 21-in deck 3-in-1 blade 532189028 is a common wear item on this model.

Is it cheaper to repair or replace a lawn mower?
If your Craftsman lawn mower model 917388964 needs a major repair that costs more than about 50% of the price of a comparable new mower, replacement is usually the cheaper long-term choice; smaller fixes and routine maintenance are typically worth repairing, especially when the mower is otherwise in good condition.
A practical repair vs. replace checklist
- Repair it when the issue is routine: dull blade, worn cable, loose hardware, clogged deck, basic tune-up.
- Replace it when the repair is major: repeated no-start after fuel and ignition checks, severe engine damage, or multiple expensive failures at once.
- Repair it when parts are inexpensive and available (blade, blade adapter, control cable, wheels).
- Replace it when the deck or engine has structural damage (cracks, severe corrosion, bent crankshaft).
- Repair it when you can do the work safely and quickly with basic tools.
Typical cost comparison (rule-of-thumb)
| Situation | What it usually means | Best value choice |
|---|---|---|
| Minor wear items (blade, cable, wheel) | Low parts cost, quick labor | Repair |
| One moderate repair (single part plus 1-2 hours labor) | Still below half the mower’s value | Repair |
| Major engine-related repair | High labor, uncertain outcome | Replace |
| Multiple systems failing (drive, engine, controls) | Costs stack up fast | Replace |
Why it matters
A walk-behind mower’s value is tied to engine health and safe cutting performance. Your 917388964 manual also emphasizes regular maintenance (spark plug, air filter, blade condition) because staying ahead of wear prevents the expensive failures that push you into replacement territory. Use the 917388964 owner’s manual to follow the maintenance schedule and troubleshooting steps before you commit to a big repair.
Parts that commonly make repair worthwhile on this model
If the mower is otherwise solid, these common replacements often restore performance at a reasonable cost:
- Husqvarna lawn mower 21-in deck 3-in-1 blade 532189028 (cut quality and vibration)
- Blade adapter 532418373 (blade mounting and alignment)
- Lawn mower zone control cable 532183281 (engine stop and operator control)
