Craftsman 917377210 rotary lawn mower Parts

On the Craftsman rotary lawn mower model 917377210, the model and serial numbers are printed on a decal attached to the rear of the mower housing (rear of the deck). We recommend writing both down and keeping them with your paperwork for parts lookup and service.

Check these common spots on walk-behind mowers like model 917377210:

• Rear of the mower deck/housing (most common)
• Between the lower handle mounts near the back of the deck
• Near the discharge opening or rear door area (less common)
• On a metal tag or adhesive decal on the deck surface

Use a flashlight and wipe off grass dust; decals can be hard to read when dirty.

The decal typically includes both identifiers. Record:

• Model number (used to match diagrams and parts lists)
• Serial number (helps confirm production run and correct part variations)
• Date of purchase (useful for maintenance tracking)

If the sticker is damaged, try these steps:

• Clean the area with mild soap and water; avoid harsh solvents that can erase printing
• Look for an “imprint” outline where the decal used to be and check nearby surfaces
• Check your paperwork for the model number (manual cover, receipt, service records)
• Use the parts diagrams in the 917377210 owner's manual to match assemblies (deck, handle, drive system) to your mower

Using the exact model number prevents ordering the wrong blade, drive belt, or hardware. For example, this model uses a 22-inch blade listed in the parts breakdown, and the correct match matters for safe cutting performance.

For the Craftsman model 917377210 rotary lawn mower, use fresh regular unleaded gasoline; in most areas, E10 (up to 10% ethanol) is the right choice. Avoid premium fuel unless your engine label or 917377210 owner's manual specifically calls for it.

• Use: fresh regular unleaded gas (commonly E10)
• Use: clean fuel from a clean, non-rusting gas can
• Avoid: old gas left over from last season
• Avoid: gasoline stored in a rusty or dirty container
• Avoid: filling the tank while the engine is hot or running (let it cool first)

The manual emphasizes checking the fuel tank before starting and fueling only when conditions are safe.

• Shut the engine off and let it cool for several minutes
• Fuel outdoors, away from ignition sources
• Fill carefully; wipe up any spills before starting
• Tighten the fuel cap securely
• Store extra gasoline safely; do not keep it from one season to the next

Fresh, clean regular unleaded fuel helps your 917377210 start easier, run smoother, and reduces carburetor and fuel-system issues caused by stale gas, dirt, or rust.
