Craftsman 917370561 lawn mower Parts

On a Craftsman walk-behind mower like model 917370561, the serial number is used to identify the production run and helps us match the correct parts and manual information. The most reliable way to interpret it is to follow the serial-number format shown for your exact mower in the 917370561 owner's manual.

Most Craftsman walk-behind mowers place the model and serial information on a label or stamped plate on the mower housing.

• Check the top of the deck near the engine
• Check the rear of the deck near the bagger door
• Check around the handle mounting area
• Wipe off grass and oil so every digit is readable
• Write the serial number exactly as shown (include letters and dashes)

Craftsman serial numbers are commonly structured so that certain digits represent a build date or manufacturing code. Some formats use a month-day-year pattern, but the exact positions vary by production series.

Use this quick process:

1. Copy the full serial number.
2. Look for a date-like grouping (often 6 digits).
3. Compare that grouping to the serial-number guidance in the manual.
4. Use the model number 917370561 plus the serial number when ordering parts.

The serial number helps ensure you get parts that match your mower’s exact configuration (especially for drive components, wheels, and control cables).

If you are matching parts by serial number, these are common items where exact fit matters:

• Lawn mower zone control cable 532191221 (operator presence control cable)
• Lawn mower 21-in deck mulching blade 532406706 (21-inch blade)
• Lawn mower blade adapter 532421176 (adapter that mates blade to the crankshaft)

For a Craftsman walk-behind mower like model 917370561, repairing is cheaper when the fix is routine maintenance or a small part; replacing is cheaper when the repair total reaches about 50% or more of the cost of a comparable new mower, or when the engine/drive system has major failure.

• Choose repair for wear items and simple fixes (blade, cable, wheel hardware, tune-up parts).
• Choose replace when the mower needs major engine work, repeated repairs, or extensive deck/drive damage.
• If the mower is still within the 2-year warranty window, check coverage details in the 917370561 owner's manual.

These are typically lower-cost and restore performance quickly:

• Sharpen or replace a worn/bent blade
• Clean packed grass from under the deck and around drive wheels
• Replace a stretched/binding control cable
• Replace worn wheel components (dust cover, bearings, hardware)
• Seasonal tune-up (spark plug, air filter, fresh fuel practices)

Replace the mower when one or more of these are true:

• Repair estimate is 50%+ of the price of a similar new mower
• The engine has low compression, heavy smoking, or internal damage
• The drive system/gear case has major failure and the mower has high overall wear
• The deck is cracked or severely rusted (structural damage)

A walk-behind mower’s best value comes from basic maintenance. The manual calls out routine checks like keeping the blade sharp, cleaning under the deck, and ensuring rear drive wheels move freely; those low-cost steps prevent bigger failures and extend mower life. See the maintenance and service guidance in the 917370561 owner's manual.

For the Craftsman lawn mower model 917370561, use 87-octane unleaded gasoline (regular) for normal operation; higher octane such as 89 does not improve performance in typical walk-behind mower engines and can add unnecessary cost. For fuel handling and storage details, follow the 917370561 owner's manual.

• Use fresh, clean, unleaded 87 octane from a clean gas can.
• Avoid old fuel from last season; it causes hard starting and rough running.
• Avoid fuel contaminated with water, dirt, or rust (replace rusty gas cans).
• Do not mix oil into the gas unless your engine specifically requires it (most 4-cycle walk-behind mowers do not).
• Fill only when the engine is off and cool, and wipe up spills.

The manual’s storage guidance is simple: do not keep gasoline from one season to the next, and keep fuel containers clean to prevent rust and debris from entering the carburetor.

• Use up fuel before long storage whenever possible.
• Store the mower indoors when practical, covered with a breathable cover.
• Never store the mower with gasoline in the tank inside a building where fumes could reach a flame or spark.

Using the right fuel helps prevent varnish and deposits in the carburetor, reduces starting problems after storage, and keeps your Craftsman 917370561 running consistently through the mowing season.

Common problems on the Craftsman 917370561 gas walk-behind mower are usually maintenance-related: loss of power, uneven cutting, excessive vibration, hard-to-pull starter rope, hard pushing, and drive issues. Most fixes start with cleaning buildup, checking the blade, and inspecting the air filter and drive system per the 917370561 owner's manual.

• Loss of power: dirty air filter, grass and debris packed under the deck, cutting too low in heavy grass
• Poor cut (uneven): worn, bent, or loose blade; wheel height set uneven; deck packed with clippings
• Excessive vibration: blade damage/looseness; bent crankshaft (stop using until inspected)
• Starter rope hard to pull: blade dragging in grass; blade adapter issue; brake engaged when control bar released
• Hard to push: grass too high, cutting height too low, catcher too full, handle height not comfortable
• Loss of drive/slowing: belt wear, belt off pulley, worn/broken drive cable, loose drive control system

1. Tip the mower safely (spark plug wire disconnected) and scrape the underside of the deck.
2. Confirm all four wheels are set to the same cutting height.
3. Inspect the blade for bends, cracks, or rounding; replace if damaged.
4. Check that rear drive wheels spin freely; clean debris from the wheel and dust cover area.
5. If self-propelled, inspect the drive control for looseness and cable wear.

A packed deck, worn blade, or restricted airflow forces the engine to work harder, reduces cut quality, and can accelerate wear on the blade adapter, drive components, and wheel bearings.

The model number for this Craftsman walk-behind gas lawn mower is 917.370561 (often written without the dot as 917370561). You can confirm it on the model tag and in the 917370561 owner's manual.

Check these common locations on Craftsman walk-behind mowers:

• On the rear of the deck near the discharge opening
• On the top of the deck near the engine mounting area
• On the handle bracket area (near the height adjusters)
• In the owner documentation that came with the mower

This mower uses a Briggs & Stratton engine, so you may see a separate engine model number on the engine shroud. That engine number is not the mower model number.

Using the exact mower model number 917.370561 helps us match the correct walk-behind mower parts list, diagrams, and hardware so you get the right blade, drive components, and fasteners the first time.

For the Craftsman 917370561 walk-behind mower, the drive belt is a V-belt listed in the parts breakdown as V-belt (drive belt). Use the belt specified for this exact model in the 917370561 owner's manual to ensure the correct length and profile for the self-propel drive.

We recommend matching the belt by model and by the drive system diagram, not by a generic belt size listing.

• Verify the mower is model 917370561 (not a riding mower model)
• Look up the drive system section and find the belt called V-belt
• Compare your old belt for width, length, and V-profile (it should sit deep in the pulley groove)
• Inspect the drive pulley and belt keeper for bending or wear that can throw a new belt
• Replace any worn drive components at the same time to prevent repeat failures

In the Craftsman 917370561 drive components list, the belt is identified as V-belt (drive belt). That is the correct belt type for the self-propel system on this 21-inch power-propelled mower.

That size is commonly associated with riding mower/tractor applications, not a 21-inch walk-behind mower like the Craftsman 917370561. Walk-behind self-propel belts are typically a different profile and length.

If the mower slips, surges, or will not move, these parts often contribute:

• Lawn mower drive control assembly 583297901 (engagement and cable routing)
• Drive cable routing and adjustment (per the manual)
• Drive pulley condition and alignment
• Wheel drive components (pawls/gears) for traction

For drive issues beyond the belt, use lawn mower wont move troubleshooting video motion drive failure to narrow down whether the problem is belt slip, cable adjustment, or wheel drive wear.
