How do I find out what kind of lawn mower I have?
To find out what kind of lawn mower you have, match the model number on the mower’s ID label to the model number used for parts and the 917374551 owner's manual. For Craftsman model 917374551, you will typically use one parts diagram for the mower and a separate one for the engine.
Where to find the model number on the mower
On most Craftsman walk-behind mowers, the model number is on an ID label or plate mounted on the mower housing or handle area. Once you have it, use that exact number (including all digits) when ordering parts.
- Check the rear of the deck near the discharge area
- Check the top of the deck near the engine mounting area
- Check the handle brackets or lower handle area
- Wipe off grass and dirt so the label is readable
- Write down the full model number and any serial number
What “kind” of mower the model number tells you
The model number identifies the mower platform (deck, drive system, controls) and helps you pull the correct parts breakdown. The engine often has its own model and type code on the engine shroud, which you use for engine-specific parts (carburetor, ignition, air filter, spark plug).
| What you’re identifying | Where to look | What it’s used for |
|---|---|---|
| Mower model (example: 917374551) | Mower ID label/plate | Deck, wheels, drive parts, handle parts |
| Engine model/type code | Engine label on shroud/valve cover | Engine tune-up and fuel/ignition parts |
Why it matters
Using the correct mower model number prevents wrong-fit parts, especially on common wear items like the blade, drive belt, and controls. For example, if you are replacing a blade on this mower, match by model and deck size, then choose the correct part such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.
Quick tip for parts diagrams
For Craftsman 917374551, expect two lookups:
- Mower parts (deck, drive, handle, bagging and discharge components)
- Engine parts (fuel, ignition, air intake, muffler)

What are the common problems with Craftsman lawn mowers?
Common problems on the Craftsman 917374551 gas walk-behind mower are no-start conditions (stale fuel, dirty air filter, bad spark plug, control bar issues), loss of power from grass buildup under the deck, uneven cutting from a worn or loose blade, and self-propel drive issues when the rear drive wheels are packed with debris. See the 917374551 owner's manual for the model-specific troubleshooting chart and maintenance steps.
Most common symptoms and what usually causes them
- Won't start: stale fuel, dirty air filter, spark plug wire off, bad spark plug, control bar not held to the handle
- Loss of power: dirty air filter, mowing too fast, heavy grass, grass buildup under the mower housing
- Poor cut (uneven): worn/bent/loose blade, uneven wheel height settings, debris under the deck
- Excessive vibration: loose blade, damaged blade, blade adapter issues, bent crankshaft after impact
- Hard to push or loss of drive: rear drive wheels not turning freely because grass and trash are packed in the wheel area
Quick checks we recommend (in order)
- Use fresh gasoline; drain and refill if fuel is old or contaminated.
- Inspect and clean or replace the air filter.
- Check the spark plug and make sure the plug wire is firmly connected.
- Look under the deck for packed grass and debris; clean it out.
- Check the blade for looseness, bends, or damage; replace if needed with an approved blade such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.
- For self-propel issues, clean both rear drive wheels so they move freely.
Common problems and the best first fix
| Problem | Most likely cause | Best first step |
|---|---|---|
| Won't start | Stale fuel, dirty air filter, bad spark plug | Refresh fuel; service air filter and spark plug |
| Uneven cut | Blade worn/bent/loose; wheel heights uneven | Set wheel heights evenly; inspect blade |
| Vibration | Loose/damaged blade; impact damage | Tighten/replace blade; inspect for damage |
| Loss of drive | Debris in rear drive wheels; worn drive parts | Clean drive wheels; inspect drive belt/cable |
Why it matters
These issues usually trace back to basic maintenance and safety controls. Keeping the blade sharp, the deck clean, and the drive wheels free of debris improves cut quality, reduces vibration, and prevents premature wear on the drive system.

What model number is the Craftsman 917374551?
The model number for this Craftsman walk-behind mower is 917.374551 (often written without the dot as 917374551). You can confirm it on the mower’s model label and in the 917374551 owner's manual.
Where to find the model number on the mower
Most Craftsman walk-behind mowers list the model number on a product label located on the deck or rear housing area.
- Check the top of the mower deck near the engine mounting area
- Look at the rear discharge door area or rear skirt
- Wipe off grass and dirt so the label is readable
- Match the label to the manual format: 917.374551
Why the dot matters (917.374551 vs 917374551)
Both formats refer to the same mower; the dot is a common way Craftsman prints the model on documentation and labels.
| You might see it as | What it means |
|---|---|
| 917.374551 | Printed model format in the manual/label |
| 917374551 | Same model number without punctuation (common online) |
Why it matters when ordering parts
Using the exact model number helps us show the correct diagrams and parts for your mower, especially for fit-critical items like the blade, drive belt, and control cables.
- Prevents ordering the wrong blade style or mounting pattern
- Helps match drive system parts (belt, pulleys, drive control)
- Ensures correct handle and control components
If you are replacing a common wear item, match the part to your diagrams and hardware; for example, the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 is a model-matched blade option shown for this mower.

What year is Craftsman Model 917374551?
Craftsman model 917.374551 is identified by its model number, not a build year. For this mower, the year is typically determined from the engine date code (on the Briggs & Stratton engine) or the product ID/serial label, using the decoding steps shown in the 917374551 owner's manual.
How to find the year on your 917.374551 mower
We use these common locations because Craftsman walk-behind mowers often do not encode the year directly in the model number.
- Check the engine shroud or valve cover area for a Briggs & Stratton date code
- Look for a product ID/serial label on the rear of the deck or near the handle mounting area
- Write down the full code exactly as shown (letters and numbers)
- Compare the code format to the identification section in the manual
- If the label is worn, clean it gently and use a flashlight to read stamped characters
What the model number does (and does not) tell you
The manual confirms this is a Craftsman rotary lawn mower, model 917.374551, but it does not list a specific manufacturing year in the excerpted pages.
| Identifier | Example | What it tells you |
|---|---|---|
| Model number | 917.374551 | Mower configuration and parts family |
| Engine model/type/code | Briggs & Stratton numbers | Engine build date and spec details |
| Product ID/serial | Deck label | Mower production run tracking |
Why it matters
Knowing the correct year (or at least the exact engine code) helps us match the right maintenance and repair parts, especially for wear items like the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 and drive components.

Where is Craftsman's model number?
On your Craftsman walk-behind mower, the model number is found on the mower’s product ID label (not on the engine). For this unit, the model is 917.374551; use that number when ordering mower parts and looking up diagrams in the 917374551 owner's manual.
Where to look on a walk-behind mower
Check these common label locations first (wipe off grass and dirt so you can read it):
- Rear of the mower deck near the discharge opening or rear door
- Top of the deck near the engine mounting area
- Back of the deck above the rear wheels
- Under the rear flap or near the bagging/mulching opening
- On the handle bracket area (less common)
Model number vs. engine numbers (why it matters)
Your mower has two different sets of identification numbers:
| What you’re identifying | Where it’s used | Where you’ll find it |
|---|---|---|
| Mower model number (917.374551) | Deck, drive system, handle, wheels, bagging and mulching parts | Product ID label on the mower deck |
| Engine model/type/code (Briggs & Stratton) | Engine-specific parts like carburetor, ignition, starter, air filter | Stamped/printed on the engine shroud or valve cover area |
If you’re buying parts like a blade, belt, or drive controls, you want the mower model number.
Tips to make the label readable
- Clean the area with a damp rag and mild soap; avoid pressure washing labels.
- Use a flashlight at a low angle to make faint printing stand out.
- Take a photo and zoom in; it is often easier than reading it on the mower.
Parts that typically use the mower model number
These are examples of parts commonly matched by 917.374551:
- Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
- Drive belt and drive control components
- Discharge deflector, mulching door, and rear skirt
Why it matters
Using the correct model number prevents ordering a part that fits a similar-looking Craftsman mower but has different deck, drive, or handle hardware.
