Craftsman 917376670 lawn mower Parts

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.

Common problems and what they usually point to

• 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

Quick checks we recommend (before buying parts)

1. Disconnect the spark plug wire and let the engine cool.
2. Tip the mower safely (air filter and carburetor side up is typical) and clear packed grass from the deck.
3. Inspect the blade for nicks, bends, and balance; tighten mounting hardware.
4. Check drive engagement: with the drive control held, look for belt slack or a belt that rides low in the pulley.
5. Spin each wheel by hand; compare left vs. right for binding or wobble.

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.

Where to find the serial number on model 917376670

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)

How to decode the year from the serial number

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

Quick decode table

Serial/date code	Month	Day	Year
072811	07	28	2011
031520	03	15	2020

What to do if your serial number does not match MMDDYY

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

Why it matters

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.
