Craftsman 917370921 lawn mower Parts

To identify what kind of mower you have, start with the model number on the mower itself. For Craftsman model 917370921, the model and serial number are on a decal on the rear of the mower housing; that number tells us the exact walk-behind mower platform and which parts diagrams match it. See the 917370921 owner's manual.

Where to look on a Craftsman 917370921 mower

Check these common ID locations first:

• Rear of the mower deck (rear housing area), on a decal
• Under the rear discharge door area (sometimes near the opening)
• On the handle support/bracket area (less common)
• On the engine shroud for the engine model and type (separate from the mower model)

Mower model vs. engine model (why there are often two diagrams)

Many walk-behind mowers, including the Craftsman 917370921, are best identified using two numbers:

What you’re identifying	Where the number is found	What it’s used for
Mower model (917370921)	Rear of mower housing decal	Deck, wheels, drive system, handle, bagging/mulching parts
Engine model (Briggs & Stratton)	Engine cover/shroud label	Carburetor, air filter, ignition, recoil starter, fuel system parts

Quick checklist to confirm you have the right model

Once you find the mower model decal, confirm these details match what you’re servicing:

• Brand: Craftsman
• Model number format: 917.xxxxxx (example: 917370921)
• Mower type: gas walk-behind mower
• Deck size: 22-inch class (common for this model family)
• Drive type: power-propelled (self-propelled)

Why it matters

Using the correct mower model number prevents ordering the wrong blade, belt, or control cable. The mower deck and the Briggs & Stratton engine use different parts lists, so matching both numbers saves time and avoids returns.

The Craftsman model 917370921 is a 22-inch walk-behind mower, not a 42-inch deck mower; our model-specific manual for 917370921 does not list an assembled weight. If you have a 42-inch Craftsman riding mower, its weight depends on that mower’s exact model number.

What we can confirm for model 917370921

The documentation for Craftsman 917370921 identifies a 22-inch rotary, power-propelled walk-behind mower (not a 42-inch rider). You can verify the mower type and key specs in the 917370921 owner’s manual.

• Model: 917370921
• Mower type: walk-behind, power-propelled
• Cutting width: 22 in.
• Engine family shown: Briggs & Stratton 725 Series
• Assembled weight: not specified in the manual

How to get the correct weight for a 42-inch Craftsman mower

Because “42-inch” typically refers to the cutting deck size on a riding mower or lawn tractor, the only reliable way to get the weight is to match the exact model number on that 42-inch machine.

• Find the model tag (commonly under the seat, on the frame rail, or near the rear fender)
• Write down the full model number exactly as shown
• Use that model number to look up the manufacturer’s specifications

Quick comparison (to avoid mixing models)

Item	Craftsman 917370921	“Craftsman 42-inch mower”
Mower style	Walk-behind	Riding mower/lawn tractor (varies)
Deck size	22 in.	42 in.
Weight in this model’s manual	Not listed	Depends on exact model

Why it matters

Weight is important for safe loading, ramps, tie-downs, and storage. Using the correct model number also prevents ordering the wrong parts, such as a walk-behind blade versus a rider deck blade (for 917370921, a compatible example is the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825).
