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.

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)

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

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)

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.

• If the decal is dirty, look for a faint outline where a sticker used to be

• Use a flashlight at a low angle to make faded printing easier to see.

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.

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

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

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).
