What are the most common issues with 917376670?
The most common issues we see with the Craftsman 917376670 walk-behind mower involve cutting performance (dull or damaged blade), self-propel/drive problems (worn belt or wheel drive parts), and wheel or height-adjustment wear. Use the 917376670 owner's manual for the correct checks, adjustments, and safety steps.
- Poor cut quality or vibration: bent/dull blade, loose blade hardware, damaged blade adapter
- Mower will not self-propel or slips: worn/loose drive belt, worn drive wheel components, transmission wear
- Uneven cutting height: worn height adjuster parts, wheel wear, deck buildup under the mower
- Rear discharge door will not close or flops: weak/broken torsion spring or damaged deflector
- Wheels wobble or drag: worn wheel, dust cover, washers, or missing retaining hardware
- Disconnect the spark plug wire and let the engine cool.
- Tip the mower safely (air filter and carburetor side up is typical) and clear packed grass from the deck.
- Inspect the blade for nicks, bends, and balance; tighten mounting hardware.
- Check drive engagement: with the drive control held, look for belt slack or a belt that rides low in the pulley.
- Spin each wheel by hand; compare left vs. right for binding or wobble.
| Symptom | Likely wear item | Example part for this model |
|---|---|---|
| Ragged cut, vibration | Blade or adapter | Lawn mower blade 532406713, lawn mower blade adapter 532421176 |
| No drive or weak drive | Drive belt | Belt 532157769 |
| Wheel wobble/poor traction | Wheel/drive wheel | Lawn mower wheel 532433121, lawn mower drive wheel 532403111 |
| Discharge door issues | Deflector spring/deflector | Lawn mower deflector shield torsion spring 532193000, deflector 532196053 |
These issues affect safety and performance. A loose or damaged blade can cause strong vibration; worn drive parts can make the mower hard to control on slopes; wheel and height-adjustment wear leads to scalping and uneven cuts.

What year is Craftsman Model 917376670 serial number?
For a Craftsman walk-behind mower like model 917376670, the year is encoded in the serial number, but the exact format depends on which identification label your mower uses. We use the date-code format shown in the 917376670 owner's manual to locate the correct label, then read the serial number as a build date.
Check these common locations first:
- On the rear of the mower deck near the discharge opening
- On the deck top surface near the engine mounting area
- On the rear skirt area behind the engine
- On the handle bracket area (near the lower handle mounts)
Many Craftsman mower serial numbers include a 6-digit date code that reads as:
- MM = month
- DD = day
- YY = year
Example:
- 072811 = July 28, 2011
| Serial/date code | Month | Day | Year |
|---|---|---|---|
| 072811 | 07 | 28 | 2011 |
| 031520 | 03 | 15 | 2020 |
If your label has more than 6 digits or includes letters, use these steps:
- Look for a separate 6-digit block within the serial number
- Check for a manufacture date printed near the serial number
- Compare the label style and location to the identification info in the 917376670 owner's manual
Knowing the build year helps us match the correct OEM parts for your mower, especially wear items like the lawn mower blade 532406713 and drive components that can vary by production run.

- Compare the part name and ID to what your mower uses.
- Replace worn “maintenance” items regularly (blade, belt, blade adapter) for best cut and drive performance.
- Keep your serial number and purchase date recorded for reference during service and parts ordering.
These are examples of parts commonly replaced on walk-behind mowers like the Craftsman 917376670:
| What you’re fixing | Typical part to check | Example part for this model |

| Wheel wobble or poor traction | Wheel, dust cover, drive pawls | Lawn mower wheel 532433121 |
Using the correct model-specific part prevents fit issues (wrong hole pattern, wrong belt length, wrong wheel offset) that can cause poor cutting, loss of self-propel drive, or premature wear. The manual also lists which items are considered normal wear parts (such as blades, blade adapters, and belts), so you can plan maintenance.
