Craftsman 917374823 lawn mower Parts

For the Craftsman 917374823 gas walk-behind mower, use fresh, clean regular unleaded gasoline with a minimum of 87 octane. Using 89 octane is fine, but it does not improve performance in normal mowing; 87 meets the engine’s fuel requirement (as long as the fuel is fresh and clean). See the owner's manual for the exact fueling and storage instructions for this model.

What we recommend for fuel (and what to avoid)

• Use regular unleaded 87 octane (or higher).
• Buy fuel you can use within 30 days to keep it fresh.
• Do not mix oil with gasoline (this is a 4-cycle mower engine setup).
• Avoid storing alcohol-blended fuel for long periods; it can cause moisture-related fuel issues during storage.
• If the mower will sit 30 days or longer, run it until the tank and carburetor are empty before storage.

87 vs 89: what changes and what does not

Fuel choice	Safe to use?	Benefit on this mower	When it makes sense
87 octane (regular)	Yes	Meets the minimum requirement	Everyday mowing
89 octane (mid-grade)	Yes	No practical gain in power or cut quality	Only if 87 is unavailable

Why it matters

Using the correct octane is less important than using fresh fuel and storing it correctly. Old fuel and long storage with fuel left in the system are common causes of hard starting, rough running, and carburetor problems on walk-behind mowers.

Related parts you may replace during tune-ups

If you are doing seasonal maintenance, it is common to inspect hardware and wear items around the deck and controls. For example, if the engine stop or blade control feels inconsistent, check the lawn mower zone control cable 532191221 for wear, binding, or damage.

Common problems we see on the Craftsman 917374823 walk-behind mower include loss of power, uneven cutting, excessive vibration, a starter rope that’s hard to pull, and drive issues (self-propelled slowing or not pulling). Most of these trace back to blade condition, grass buildup, cutting height, or routine tune-up items listed in the owner's manual.

Most common symptoms and what usually causes them

• Loss of power: cutting too low, mowing too much at once, dirty air filter, or grass buildup under the deck
• Poor cut (uneven): worn or bent blade, uneven wheel height settings, or debris packed under the deck
• Excessive vibration: loose or damaged blade, or a bent crankshaft after striking an object
• Starter rope hard to pull: blade dragging in grass, brake engaged, or impact-related damage
• Hard to push: cutting height too low, heavy grass, or handle height not set comfortably
• Loss of drive / slow drive: belt wear, belt off pulley, or a worn/broken drive cable

Quick checks we recommend before replacing parts

1. Shut the engine off and disconnect the spark plug wire.
2. Tip the mower safely (air filter and carburetor side up) and clear packed grass from under the deck.
3. Verify all four wheels are set to the same cutting height.
4. Inspect the blade for bends, cracks, or heavy rounding.
5. Check for loose fasteners around the blade and handle.
6. If self-propelled performance is weak, inspect the drive system and cable routing.

Parts that commonly get replaced on this model

Problem	Part that often fixes it	Example from this model’s parts list
Self-propelled won’t pull or slips	Drive cable	Lawn mower drive cable 583180101
Engine stops when you release the handle bar	Zone control cable	Lawn mower zone control cable 532191221
Vibration or poor cut	Blade (inspect first)	Husqvarna lawn mower 21-in deck 3-in-1 blade 532189028

Why it matters

Catching these issues early helps protect the crankshaft, blade adapter area, and drive components. Simple steps like raising cutting height and cleaning the deck often restore power and cut quality without major repairs.

The model number for this Craftsman walk-behind mower is 917.374823 (often written without the dot as 917374823). You can confirm it on the model tag and in the 917374823 owner's manual, which lists the mower as a Craftsman rotary lawn mower model 917.374823.

Where to find the model number on the mower

Check these common locations first (clean off grass and dirt so the label is readable):

• Rear of the deck near the discharge chute
• Top of the deck near the engine mounting area
• On the handle support/bracket area
• Near the rear wheel height adjuster area
• Inside the rear door area (if equipped)

Model number vs. engine number (common mix-up)

Many mowers have multiple labels. Use the mower model number (917.374823) when ordering Craftsman chassis and drive parts.

Label type	What it identifies	When you use it
Mower model number	The Craftsman mower (deck, handle, drive system)	Parts lookup for wheels, cables, pulleys, hardware
Engine model/type/code	The engine manufacturer and build info	Engine-specific parts like carburetor or ignition items

Why it matters

Using the exact model number helps match the correct diagrams and parts for your specific build. For example, this model’s parts list includes items like the lawn mower drive cable 583180101 and the husqvarna lawn mower 21-in deck 3-in-1 blade 532189028, which can vary by mower series.

Ordering the right parts

When you shop parts for Craftsman model 917374823, we recommend:

• Match the model number exactly (including any dots on the tag)
• Compare the part name and part ID to your diagram
• Replace worn fasteners when needed (lock nuts, washers, E-rings)
• Use the parts list for this model first; then search by model on Sears PartsDirect if you are cross-checking other Craftsman equipment

Craftsman model 917.374823 is identified by its model number (not a built-in “year” field). For this walk-behind mower, the most reliable way to date it is by checking the product ID/serial information on the mower’s label and matching it to the date-code guidance in the 917374823 owner's manual.

Where to find the date information on the mower

On Craftsman walk-behind mowers like the 917374823, the date is typically tied to the product label (often on the deck, rear housing, or near the handle mounting area), not the model number printed in the manual.

Look for a label that includes one or more of these:

• Serial number (sometimes called product number)
• Date code or manufacture code
• Engine model and type (engine date may differ from mower assembly date)
• A longer product number separate from the 917.374823 model

How to interpret what you find

Because Craftsman date coding varies by era and supplier, we use the label details to determine the year.

Here is the practical approach:

• Write down the full serial or product number exactly as shown.
• If the label includes a date code, record it as-is (letters and numbers).
• Use the diagrams and identification info in the 917374823 owner's manual to confirm you are reading the correct label for the mower (not just the engine).

Quick guide: model number vs. serial/date code

What you have	What it tells you	Best use
Model number 917.374823	The mower’s configuration and parts family	Ordering correct parts and using the right manual
Serial number / date code	The build date or production run	Determining the year
Engine numbers	Engine build details	Engine-specific service parts

Why it matters

Knowing the year helps when you are matching handle hardware, drive system parts, and deck components that can change across production runs. For example, this model’s parts list includes items like the lawn mower drive cable 583180101 and husqvarna lawn mower 21-in deck 3-in-1 blade 532189028, which must match your exact configuration.

Ordering the right parts

We recommend using the model number 917374823 plus your mower’s label details when selecting parts from the list for this model, or searching by model on Sears PartsDirect.
