What are the most common issues with 917388553?
The most common issues we see on the Craftsman 917388553 gas walk-behind mower are no-start or stalling, poor cut quality, and drive or height-adjust problems. These usually trace back to routine maintenance items, blade and adapter wear, or loose and worn hardware; use the owner's manual for model-specific checks and adjustments.
- Won’t start or starts then dies: stale fuel, dirty air filter, fouled spark plug, carburetor varnish, or a misadjusted/binding engine control cable.
- Rough running or surging: restricted fuel flow, dirty carburetor, or governor linkage issues.
- Poor cut quality or vibration: bent/dull blade, loose blade hardware, or a worn blade adapter.
- Uneven cutting height: worn wheel/axle hardware, bent brackets, or selector parts not holding position.
- Handle won’t stay set or folds unexpectedly: loose handle bolts/knobs or worn brackets.
If you’re troubleshooting cut quality, vibration, or height adjustment on model 917388553, these parts are frequent suspects:
- Husqvarna lawn mower 21-in deck 3-in-1 blade 532189028
- Lawn mower blade adapter 532418373
- Walk-behind lawn mower engine cable 532176556
- Lawn mower axle 532186575
- Wheel bracket 532407494
- Disconnect the spark plug wire before inspecting the blade or underside.
- Tip the mower with the air filter and carburetor side up (common best practice) to reduce fuel/oil leakage.
- Inspect the blade for bends, cracks, and heavy nicks; confirm the blade bolt is tight.
- Check the blade adapter for rounding, wobble, or damage where it mates to the crankshaft.
- Verify the height adjusters and wheel brackets move freely and lock into position.
| Symptom | Most likely area | Typical fix |
|---|---|---|
| Vibration | Blade/adapter | Replace blade or adapter; tighten hardware |
| Uneven cut | Height adjust/wheels | Free up adjusters; replace worn axle/brackets |
| Engine won’t stop or won’t stay running | Control cable | Inspect/replace engine cable; adjust per manual |
Catching blade, adapter, and hardware wear early prevents excessive vibration that can damage the deck, loosen fasteners, and reduce cut quality over time.

What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” label usually refers to the engine rating, not one single mower model number. For the mower on this page, the model number is 917.388553 (often written without the dot as 917388553); you can confirm it on the rear housing decal and in the 917388553 owner's manual.
We recommend using the mower’s ID decal first, then matching it to the manual and parts list.
- Look for the decal on the rear of the mower housing.
- Record both the model number and serial number.
- Match the number format exactly (some decals include a dot, like 917.388553).
- Use the model number to select the correct parts (blade, blade adapter, cables, hardware).
- If the decal is worn, compare your handle and deck style to the diagrams in the manual.
Many Craftsman walk-behind mowers were sold with similar engine ratings (6.5, 6.75, etc.) across multiple model numbers. That means two different mowers can both be called “Craftsman 6.75” but use different blades, control cables, or handle hardware.
| What you have | What it tells you | What to use for parts |
|---|---|---|
| “6.75” on engine cover | Engine power family | Not enough by itself |
| Model number on rear housing decal | Exact mower identity | Correct parts lookup |
| Owner’s manual model number | Confirms configuration | Correct procedures/specs |
Using the correct model number prevents ordering the wrong wear items and safety-related parts. For example, this Craftsman 917388553 uses a specific blade and blade adapter combination, such as the husqvarna lawn mower 21-in deck 3-in-1 blade 532189028 and the lawn mower blade adapter 532418373.

What year is Craftsman Model 917388553?
Craftsman model 917388553 is identified in the documentation as a Craftsman rotary lawn mower (6.5 HP, 21-inch rear discharge). The year is not encoded in the model number itself; the build date is determined from the mower’s serial number/date code on the rear housing decal (not from “917”).
Use the mower’s serial number decal on the rear of the lawn mower housing and decode the date information from that label using the format shown in the 917388553 owner’s manual.
- Locate the decal on the rear housing (near the deck)
- Write down the full serial number exactly as shown
- Look for a date code segment (often grouped digits)
- Decode the date code into month, day, and year (if your label uses that format)
- Record the serial number and purchase date for future parts lookups and service
| Item | What it tells you | Where to find it |
|---|---|---|
| Model number (917388553) | Which parts diagram and manual match your mower | On the mower label and in the manual |
| Serial number/date code | The manufacturing date (year) | Rear housing decal |
The manufacturing year helps us match the correct blade, blade adapter, control cable, and hardware revisions that can change across production runs. For example, if you’re servicing the cutting system, using the correct husqvarna lawn mower 21-in deck 3-in-1 blade 532189028 and compatible fasteners prevents vibration and poor cut quality.
