How to read a Craftsman mower serial number?
On Craftsman walk-behind mower model 917378200, the serial number is primarily used to identify your exact unit for parts and service; the most reliable first step is to find the serial decal on the rear of the mower housing and record it exactly as shown in the 917378200 owner's manual.
We see the serial number location called out for this model on a decal at the rear of the mower housing.
- Look on the rear of the lawn mower housing (near the deck, behind the engine area)
- Write down both the model number and serial number
- Record the date of purchase if you still have it
- Take a clear photo of the decal before it gets worn or dirty
Craftsman serial-number formats vary by mower family and production run. Many Craftsman mowers use a date-coded serial number (often read as month, day, year in the first six digits), but the exact pattern depends on the label format printed on your mower.
| If the serial starts with | Often represents | Example result |
|---|---|---|
| 2 digits | Month (MM) | 07 = July |
| next 2 digits | Day (DD) | 28 = 28th |
| next 2 digits | Year (YY) | 11 = 2011 |
Reading the serial number correctly helps us match the right Craftsman parts (blade, drive belt, control cable) to your exact build, which prevents ordering a part that looks similar but mounts differently.
- Match by model number first: 917378200
- Use the serial number to confirm the correct version when parts lists show multiple options
- For cutting and drive issues, common wear items include the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 and the poulan lawn mower ground drive belt, 3/8 x 35-1/2-in 580364604

What are the common problems with Craftsman lawn mowers?
Common problems we see on the Craftsman 917378200 walk-behind mower are hard starting, loss of power, poor cut quality, excessive vibration, starter rope that is hard to pull, and self-propel drive issues. Most fixes start with basic maintenance and a quick inspection using the 917378200 owner's manual.
- Won’t start or starts then dies: old fuel, dirty carburetor, fouled spark plug, dirty air filter
- Loss of power: grass buildup under the deck, cutting height too low, dirty air filter, oil level issues
- Poor cut or uneven cut: dull, bent, or loose blade; uneven wheel height settings; deck packed with clippings
- Excessive vibration: worn/bent/loose blade; impact damage (possible crankshaft issue)
- Starter rope hard to pull: control bar not held to the handle; blade dragging in grass; damaged blade adapter
- Self-propel won’t move or slows: worn belt, belt off pulley, worn/broken drive cable
- Make it safe: disconnect the spark plug wire before working near the blade.
- Check the control bar: hold it against the upper handle before pulling the starter rope.
- Look under the deck: remove packed grass and debris (a common power and cut-quality killer).
- Inspect the blade and hardware: tighten a loose blade; replace a bent or damaged blade.
- Check drive wheels: if they do not turn freely, clean debris from the wheel area.
| Problem | Common fix | Example part for this model |
|---|---|---|
| Poor cut, vibration, bent blade | Replace blade | 22-inch deck 3-in-1 blade 532421825 |
| Rope hard to pull, vibration after impact | Inspect blade adapter | Blade adapter 581851501 |
| Loss of drive or slow drive | Replace belt | Ground drive belt 580364604 |
| Loss of drive, drive won’t engage | Replace cable/drive control | Drive control assembly with cable 589818808 |
A dull or damaged blade and grass buildup under the mower housing can cause poor cutting, extra vibration, and engine strain. Keeping the blade sharp, the deck clean, and the drive system adjusted helps your Craftsman mower run smoother and last longer.
