Craftsman 917374150 lawn mower Parts

For the Craftsman lawn mower model 917374150, use regular unleaded 87-octane gasoline for normal operation. Higher octane (like 91) is not required for performance; the most important thing is using clean, fresh fuel and storing it correctly per the 917374150 owner's manual.

• Use fresh, regular unleaded 87 octane.
• Avoid old gas (stale fuel is a top cause of hard starting and rough running).
• Avoid fuel contaminated with water or dirt.
• If your area offers ethanol-free fuel, it can help reduce storage issues, but 87 octane is still the right octane level.
• Use a fuel stabilizer when fuel will sit (the manual lists stabilizer as a recommended accessory).

Octane is mainly about preventing knock in high-compression engines. Most walk-behind mower engines are designed to run correctly on regular fuel, so paying for premium usually does not improve power, starting, or engine life. Fuel quality and storage habits matter more than octane.

• Buy gas in small amounts so you use it up quickly.
• Add stabilizer if the mower will sit for more than a short period.
• Keep the gas can sealed and stored in a cool, dry place.
• If the mower starts running poorly, check maintenance items like the spark plug and air filter (the manual calls for spark plug replacement at the start of each season or every 100 hours).

The model number for this Craftsman walk-behind lawn mower is 917.374150 (often written without the dot as 917374150). You’ll see it printed on the mower’s model tag and on the cover page of the 917374150 owner's manual.

Look for a model and serial number label on the mower body. Common locations include:

• On the rear of the deck near the discharge opening
• On the back panel near the rear wheels
• Near the handle mounting brackets
• Under the rear door area (bagging opening)

Both formats refer to the same mower; the dot is just a formatting style used in some manuals and parts lists.

When ordering parts for a Craftsman mower, we recommend confirming the full model number from the label because small differences can change the blade, drive system, or handle parts.

• Match the model number exactly: 917374150
• Use the mower’s product label, not the engine label (Briggs & Stratton numbers are different)
• If you’re replacing cutting parts, confirm deck size (this model uses a 22-inch blade)
• If you’re working on the self-propel system, verify drive components like the lawn mower drive control cable 588479201

The model number is the key to getting the correct diagrams, hardware, and replacement parts (blade, drive cable, wheels, and transmission). Using the exact model number prevents ordering parts that do not fit.

Craftsman model 917374150 is a model number (not a date code), so it does not directly tell the year. To identify the year, we use the mower’s product label date code or the engine identification details shown in the 917374150 owner's manual.

Look for a product label on the mower (commonly on the rear of the deck, near the handle brackets, or on the housing). The label typically includes a serial number or date code.

Common places to check:

• Rear of the mower deck (near the discharge opening)
• Under the rear door or near the rear skirt
• Handle bracket area
• Engine shroud label (Briggs & Stratton engine tag)

The documentation identifies this as a Craftsman rotary lawn mower, power-propelled, 22-inch multi-cut, using a Briggs & Stratton 675 Series engine (model family shown as 126L02-xxxx in the parts listing).

Knowing the year helps us match the correct parts and diagrams for wear items like the blade, drive system, and rear door components. For example, this model uses a 22-inch blade listed as lawn mower 22-in deck 3-in-1 blade 532420463.
