Craftsman 917376040 rotary lawn mower Parts

Gas walk-behind mowers like the Craftsman 917376040 are not being phased out everywhere at once, but new gas mower sales are trending downward as some states and cities tighten emissions and noise rules and more homeowners switch to battery-electric models. Gas mowers will remain common for years, especially for larger yards and heavy cutting.

What “phased out” usually means (and what it does not)

Most changes affect new equipment sales, not the mower you already own.

• Some areas restrict or plan to restrict new gas-powered outdoor equipment sales.
• Many places still allow gas mower sales with no special restrictions.
• Existing gas mowers are typically still legal to own, use, and repair.
• Parts support often continues long after sales slow down.
• Commercial crews may keep gas longer due to runtime and refueling speed.

How this impacts your Craftsman 917376040

If you plan to keep your mower running, the practical focus is maintenance and wear parts.

• Keep the blade sharp and balanced for cleaner cuts and less engine load.
• Replace worn drive and deck components when performance drops.
• Use fresh fuel and proper storage practices to avoid carburetor issues.

Why it matters

Regulations and retailer trends can influence what is easiest to buy next, but they do not stop you from maintaining a reliable gas rotary lawn mower. Keeping the cutting system and drive system in good shape protects the engine and improves mowing results.

To identify your Craftsman rotary lawn mower model, start with the mower’s model tag and record the full model number (for this unit: 917376040). If the tag is missing or unreadable, use the engine’s model and code numbers stamped on the engine to match the correct parts.

Where to look on Craftsman model 917376040

Most walk-behind mowers have a model/serial label on the mower deck or handle area. Check these common spots:

• Rear of the deck near the discharge chute
• Top of the deck behind the engine
• Near the height adjuster area on the deck
• On the handle support or handle bracket
• Under the rear flap (if equipped)

If the mower tag is missing: find the engine numbers

The engine often has its own identification numbers stamped or printed on metal. Common locations include:

• Blower housing (recoil starter shroud)
• Muffler heat shield
• A few inches above the spark plug
• Fuel tank area
• Base of the engine block

Quick comparison: mower model vs. engine model

What you find	What it identifies	When to use it
Mower model number (example: 917376040)	The mower and its chassis parts	Wheels, deck parts, drive parts, handle hardware
Engine model/type/code	The engine itself	Carburetor, ignition parts, recoil starter parts

Tips to avoid ordering the wrong parts

Use these checks before you buy parts like a blade, wheel, or belt:

• Write the model number exactly as shown (all digits matter)
• Clean the label area and engine stamping with a dry rag before reading
• Match the part to the mower system (deck/drive/handle) versus engine system
• If you are replacing cutting parts, confirm whether you need a blade adapter too
• Compare your old part’s shape and mounting points to the replacement listing

If you are working on the cutting system, the lawn mower blade 532406713 is a common model-matched part to verify against your existing blade.

Why it matters

The mower model number (917376040) controls fit for Craftsman deck, drive, and handle parts, while the engine numbers control fit for engine components. Using the correct identifier prevents mismatched blades, belts, wheels, and hardware.

For under $300, the best gas mower is the one that fits your yard size and is easy to maintain; for most homeowners, a 21- to 22-inch walk-behind mower with a reliable OHV engine and simple height adjustment delivers the best value. If you already own a Craftsman model 917376040, keeping the blade and drive system in top shape usually beats replacing the mower.

What to look for (so you buy once)

• Deck size: 21 to 22 inches is the sweet spot for most small to medium lawns.
• Cut options: mulching (and bagging if you want cleaner cleanup).
• Height adjustment: single-lever or easy multi-position adjusters.
• Drive type: push is simplest; self-propelled helps on slopes and thicker grass.
• Serviceability: easy access to blade, wheels, and belt/drive cover.

Quick comparison: what matters most under $300

Feature	Best for	What to choose
Deck width	Faster mowing	21 to 22 in
Engine style	Easy starting, steady power	OHV gas engine
Drive	Hills and larger yards	Self-propelled
Maintenance	Lower long-term cost	Common blade and wheel parts

If your current mower is a Craftsman 917376040

A “best” mower often becomes “your mower after a tune-up.” These are the most common value repairs:

• Replace a worn or bent blade with the correct OEM-style blade such as the lawn mower blade 532406713.
• Fix poor cutting or vibration by checking the blade adapter such as the lawn mower blade adapter 581547901.
• If it will not roll smoothly or the height will not hold, inspect the lawn mower wheel assembly 532180775 and height hardware.
• If self-propel feels weak or slips, inspect the belt and cover area (common wear items include the belt 532157769 and lawn mower drive cover 582952501).

Why it matters

Choosing the right deck size and drive type prevents bogging, uneven cuts, and premature wear. On an existing mower, a sharp blade, solid blade adapter, and smooth-rolling wheels are the fastest way to restore cut quality and reduce strain on the engine.
