What model number is the Craftsman 917388600?
The model number is 917.388600; it’s printed on the Craftsman rotary lawn mower’s identification label and shown on the cover of the 917388600 owner's manual. This is the correct model number to use when ordering parts and looking up specifications.
Where to find the model number on the mower
We typically see the model number on the mower’s model and serial tag (often on the rear of the deck, near the handle mounting area, or on the housing).
- Look for a label that says Model No.
- Confirm it reads 917.388600 (including the dot)
- Write down the serial number too (helpful for parts lookups)
- Use the model number when matching parts like the control bar, blade, or cables
Model number vs. engine model number (common mix-up)
This mower has a separate engine model number listed in the manual; that engine number is used for engine-specific parts, not the mower chassis parts.
| What you’re identifying | Example from documentation | Used for |
|---|---|---|
| Mower model number | 917.388600 | Deck, handle, wheels, blade, controls |
| Engine model number | 143.024202 | Carburetor, ignition, internal engine parts |
Why it matters
Using 917.388600 ensures you get the right Craftsman walk-behind mower parts and diagrams. If you use an engine number or a marketing name, you can end up with the wrong blade adapter, control cable, or hardware.

What are the most common issues with 917388600?
On the Craftsman 917388600 gas walk-behind lawn mower, the most common problems are no-start or hard-start, poor cut quality, and drive or control issues. These usually trace to fuel/ignition maintenance, blade and adapter wear, or stretched/binding control cables; use the owner's manual for model-specific adjustments.
Common symptoms and what they usually mean
- Won’t start / starts then dies: stale fuel, dirty carburetor, fouled spark plug, or restricted air flow
- Rough running / surging: fuel restriction, carburetor varnish, or air leak at fuel line connections
- Uneven cut / vibration: bent or dull blade, loose hardware, or worn blade mounting parts
- Blade won’t spin smoothly: damaged blade adapter or debris packed under the deck
- Control bar or engine brake feels wrong: cable out of adjustment, kinked, or binding
Quick checks we recommend (safe, fast)
- Turn the engine off and disconnect the spark plug wire before inspecting under the deck.
- Confirm fresh fuel; drain old fuel if it smells sour or looks dark.
- Check the blade for bends, cracks, and heavy nicks; replace if damaged.
- Inspect the blade mounting stack for looseness or wear; a worn adapter can cause wobble.
- Verify the control bar fully engages and returns freely; check cable routing for sharp bends.
Parts that commonly solve these issues
| Symptom | Common wear item | Example part for this model |
|---|---|---|
| Vibration, poor cut | Blade or mounting | Lawn mower blade, 20-in 532145106, lawn mower blade adapter 581547901 |
| Control doesn’t feel right | Control cable | Husqvarna lawn mower zone control cable 532424983 |
| Bagging problems | Bag/frame | Lawn mower grass bag 583327601, lawn mower grass bag frame 532088614 |
Why it matters
Running with a loose blade, worn adapter, or binding control cable can create excessive vibration, reduce cut quality, and accelerate wear on the crankshaft area and deck hardware.

What is the average lifespan of 917388600?
A Craftsman gas walk-behind lawn mower like model 917388600 typically lasts 8 to 12 years with normal residential use and routine maintenance (oil changes, blade care, clean air intake, and proper storage). Heavy use and poor maintenance shorten life; consistent upkeep extends it.
What most affects lifespan
- Engine maintenance: regular oil changes, clean cooling fins, and correct spark plug condition
- Blade condition: a bent or dull blade increases vibration and engine load
- Fuel habits: fresh fuel and clean carburetor passages reduce hard-start and surging issues
- Deck care: keeping the underside clean helps airflow and cut quality
- Storage: dry storage and off-season prep prevent corrosion and fuel system problems
Quick maintenance schedule (typical)
| Task | Typical interval | Why it matters |
|---|---|---|
| Change engine oil | Every season or ~25 hours | Reduces wear in the 4-cycle engine |
| Sharpen/replace blade | 1 to 3 times per season | Improves cut, reduces vibration |
| Inspect control cable and handle hardware | Every season | Keeps the zone control and safety features working |
| Clean deck underside | As needed | Prevents clumping and rust |
Parts that commonly drive “end of life” decisions
If the mower still starts and runs well, replacing a few wear items often restores performance:
- A worn or damaged blade (this model uses a 20-inch blade) such as the lawn mower blade, 20-in 532145106
- A damaged blade mount interface such as the lawn mower blade adapter 581547901
- A stretched or sticking safety/zone control cable such as the husqvarna lawn mower zone control cable 532424983
Why it matters
Most “mower lifespan” is really engine and deck condition. Keeping the blade balanced and the engine serviced prevents vibration, hard starting, and premature crankshaft or deck damage.
For model-specific maintenance steps and specifications, follow the 917388600 owner's manual.
