What are the common problems with Craftsman lawn mowers?
On the Craftsman 917388810 gas walk-behind lawn mower, the most common problems we see are no-start conditions (fuel, spark, or air issues), loss of power from heavy grass or deck buildup, uneven cutting from blade or wheel-height issues, and vibration caused by a damaged or loose blade system. See the 917388810 owner's manual troubleshooting chart for symptom-by-symptom fixes.
Most common symptoms and what usually causes them
- Won’t start: dirty air filter, out of fuel, stale or water-contaminated fuel, spark plug wire off, bad spark plug
- Loss of power: cutting too low in heavy grass, dirty air filter, grass and debris packed under the deck
- Poor or uneven cut: worn or bent blade, wheel heights set uneven, deck packed with clippings
- Excessive vibration: loose blade hardware, worn or bent blade, damaged blade adapter
- Starter rope hard to pull: blade dragging in grass, blade adapter problems, engine brake engaged when control bar is released
Quick checks we recommend before buying parts
- Tip the mower safely (spark plug wire disconnected) and clear packed grass from under the deck.
- Confirm the control bar is held against the handle when starting.
- Replace or clean the air filter and install a fresh spark plug.
- Drain stale fuel and refill with fresh gasoline.
- Inspect the blade area for looseness or damage; a loose blade can also cause a no-start.
Parts that commonly get involved
| Symptom | Part area to inspect | Example part for this model |
|---|---|---|
| Vibration or no-start with blade looseness | Blade mounting hardware | Lock nut 532409149 |
| Vibration, poor cut, starter rope hard to pull | Blade adapter and blade mounting | Lawn mower blade adapter 581547901 |
| Clippings blowing out the side | Discharge opening/guard | Discharge guard 589482402 |
Why it matters
Catching these issues early protects the crankshaft, improves cut quality, and prevents repeat no-start problems caused by stale fuel, restricted airflow, or a clogged mower deck.

What year is Craftsman Model 917388810?
Craftsman model 917388810 is identified by its model number, which does not include the manufacturing year. To determine the year, we use the serial number date code on the decal located on the rear of the mower housing; the date code format is explained in the 917388810 owner's manual.
How to find the date code on your mower
We use the mower’s identification decal to get the serial number and date information.
- Turn the mower off and let the engine cool completely.
- Locate the decal on the rear of the lawn mower housing.
- Write down the serial number and any date code shown.
- Compare the code format to the identification section in the manual.
- Keep the date with your records for maintenance and parts ordering.
Common date-code format (what the numbers usually mean)
Many Craftsman walk-behind mowers use a date code where groups of digits represent month, day, and year. Once you match your mower’s code to the format in the manual, you can convert it to a calendar date.
| Code group | Typically represents | Example meaning |
|---|---|---|
| First 2 digits | Month | 07 = July |
| Next 2 digits | Day | 28 = 28th |
| Next 2 digits | Year | 11 = 2011 |
Why it matters
Knowing the build date helps us match the correct Craftsman parts (like a blade adapter, belt, or control cable) because production changes can affect which part fits your exact mower configuration.
