Craftsman 917377061 rotary lawn mower Parts

On the Craftsman rotary lawn mower model 917377061, the model and serial number are on a decal on the rear of the mower housing (deck). We recommend writing both down exactly as shown before ordering parts or checking specifications in the 917377061 owner's manual.

Check these common spots on this exact mower:

• Rear of the mower deck, near the discharge area
• Rear panel of the housing, above the wheels
• On the deck surface near the engine mounting area (less common)
• Near the height adjuster brackets (less common)

The decal typically includes more than one identifier. Record:

• Model number (for this mower: 917377061)
• Serial number (unique to your mower)
• Date of purchase (helpful for maintenance tracking)

Craftsman model numbers can look similar across different walk-behind mowers, but small design changes can affect fit for parts like the blade, drive components, and hardware. Using the exact model number helps us match the correct diagrams and compatible replacement parts.

On the Craftsman rotary lawn mower model 917377061, the “parts on a lawn mower” include the cutting system (blade and deck), operator controls (handle and control bar), discharge and mulching components, wheels and height adjusters, and the engine and fuel/ignition items. For the full model-specific breakdown, use the 917377061 owner’s manual.

These are the major assemblies called out in the model’s diagrams and parts lists:

• Handle and controls: upper/lower handle, control bar (operator presence control), drive control components
• Cutting system: mower blade, blade adapter, blade bolt and washers
• Deck and discharge: mower housing (deck), rear door, discharge guard, debris shield
• Mulching and bagging: mulcher plug, mulcher door assembly, grass bag and frame
• Wheels and height adjustment: front/rear wheels, wheel adjuster assemblies, selector knobs, brackets
• Drive system (self-propelled models): drive belt, pulleys, idler arm/pulley, gear case, drive cable
• Engine system: fuel tank/cap, air filter, spark plug, muffler, recoil starter (engine parts are listed separately)

On this model, these are common wear items to inspect and replace as needed:

• Husqvarna lawn mower 21-in deck 3-in-1 blade 532189028 (cut quality and vibration)
• Air filter cartridge (engine performance)
• Spark plug (starting and running)
• Drive belt (loss of self-propelled drive)
• Wheels and height adjuster components (uneven cut, wobble)

Knowing the major assemblies helps you troubleshoot faster. For example, “uneven cut” usually points to the blade, deck buildup, or wheel height settings, while “won’t move” points to the drive belt/cable and pulleys.

For the Craftsman 917377061 rotary lawn mower, we recommend using fresh, clean, regular unleaded gasoline with a minimum of 87 octane (87 AKI). Do not mix oil with the gasoline; this model uses separate engine oil in the crankcase. See the 917377061 owner's manual for fueling and storage details.

Use fuel that helps the engine start easily and protects the carburetor and fuel system.

• Use regular unleaded gasoline, 87 octane minimum.
• Use fresh fuel; buy only what you can use in about 30 days.
• Do not mix 2-cycle oil into the gas (this is a 4-cycle engine).
• Avoid old or stale gas; it can cause hard starting, surging, or stalling.
• Be careful with alcohol-blended fuels; they can attract moisture during storage.

If you will store the mower for 30 days or longer, we recommend one of these approaches:

• Add fuel stabilizer to the tank and run the engine a few minutes so treated fuel reaches the carburetor.
• Or drain/empty the fuel system by running the engine until it stops.
• Store fuel only in an approved container.

For more guidance on preventing fuel issues, use how to keep lawn mower gas from going bad.

Using the correct unleaded fuel and keeping it fresh helps prevent varnish and gum buildup in the carburetor, reduces starting problems, and supports consistent power under load.

A gas walk-behind mower like the Craftsman 917377061 typically lasts 8 to 10 years with normal residential use and routine maintenance. Many units run longer when the engine is kept clean, oil is changed on schedule, and wear items (blade, belt, air filter, spark plug) are replaced as needed.

• Maintenance frequency (oil changes, air filter service, blade care)
• Fuel quality and storage habits (stale fuel is a common engine killer)
• Operating conditions (dusty, sandy, or very tall grass increases wear)
• Deck and drive system care (cleaning under the deck and drive cover)
• How often it’s used (weekly mowing vs. occasional use)

We recommend following the schedule in the 917377061 owner’s manual. Key habits that extend life:

• Check engine oil before each use
• Change engine oil about every 25 hours or each season
• Clean or replace the air filter regularly (more often in dusty conditions)
• Keep the underside of the mower deck scraped clean after mowing
• Inspect and tighten blade hardware; replace worn cutting parts

If your mower is cutting poorly or vibrating, replacing the blade is often the quickest improvement; for this model, a compatible option is the husqvarna lawn mower 21-in deck 3-in-1 blade 532189028.

Replacing a few low-cost maintenance parts on time can prevent expensive engine or drive damage. That is usually what separates a mower that lasts 5 to 6 years from one that reaches (or exceeds) 10 years.
