Craftsman 917376545 lawn mower Parts

Use 87-octane regular unleaded in your Craftsman lawn mower model 917376545. Our manual also allows gasoline with up to 10% ethanol (E10); using fuel with more than 10% ethanol can cause problems and can void the warranty. See the fuel guidance in the owner's manual.

What to use (and what to avoid)

• Use: fresh, clean regular unleaded 87 octane
• OK: E10 (up to 10% ethanol)
• Avoid: E15, E20, E85 (anything over 10% ethanol)
• Do not mix oil with gasoline (this is a 4-cycle mower engine)
• Buy only what you can use in about 30 days to keep fuel fresh

87 vs 89: what changes?

Higher octane (like 89) is not required for this mower. Octane mainly affects resistance to knock; it does not add power in small engines designed for 87.

Fuel choice	Works in 917376545?	When it makes sense
87 octane (regular)	Yes (recommended)	Normal mowing and best match to the manual
89 octane (mid-grade)	Yes	Only if it is the freshest option available
Over 10% ethanol blends	No	Can damage the fuel system and create running issues

Why it matters

Using the right fuel helps prevent hard starting, surging, and carburetor varnish. Ethanol-heavy fuel also attracts moisture, which can separate during storage and lead to corrosion and poor performance.

Quick storage tip (prevents most fuel problems)

If the mower will sit 30 days or longer:

• Run the engine until the tank and carburetor are empty, or
• Drain the tank safely, then run the engine until it stops

For a Craftsman mower like model 917376545, the serial number (not the model number) is what you use to identify the build date. Many Craftsman walk-behind mowers use a 6-digit date code format where the last two digits indicate the year; confirm the exact serial label format for your unit using the owner's manual.

Where to find the serial number

Check these common locations on a Craftsman walk-behind mower:

• On the rear of the deck near the discharge opening
• On the top of the deck near the engine mount area
• On the rear skirt area (behind the bagger opening)
• On a label near the height adjuster bracket
• On the handle mounting area

How to read common Craftsman date-style serial numbers

A very common format is MMDDYY (6 digits):

• MM = month (01 to 12)
• DD = day (01 to 31)
• YY = year (last two digits)

Example

If the serial/date code is 072811, that reads as July 28, 2011.

Quick reference table

Serial/date code format	What it means	Example	Result
MMDDYY	Month, day, year	072811	July 28, 2011
MMDDYYYY	Month, day, 4-digit year	07282011	July 28, 2011

Why it matters

Knowing the build year helps us match the correct parts and diagrams for wear items like the blade, wheels, and drive components. For example, model 917376545 commonly uses parts such as the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825 and drive system items listed in the parts breakdown.

Tips to avoid mix-ups

• Use the model number (917376545) to pull the correct parts list
• Use the serial number to confirm production date when multiple revisions exist
• If your label includes letters, copy the full string exactly (letters and numbers)

Repairing your Craftsman 917376545 walk-behind mower is cheaper when the fix is a common wear item (blade, belt, wheels) and you do the work yourself; replacing the mower is usually cheaper when the transmission or engine has major internal damage or when you are paying for labor.

A practical way to decide

Use this quick checklist before you spend money:

• If the mower still starts and runs, repairs are usually the best value.
• If it will not start, check basic tune-up items first (fuel, spark plug, air filter) before deciding.
• If it vibrates heavily or cuts unevenly, a blade or blade hardware repair is typically cost-effective.
• If it is hard to push or loses drive, check the drive belt and drive system before replacing the mower.
• If the crankshaft is bent or the engine has severe internal issues, replacement is usually the better value.

For model-specific troubleshooting steps (loss of power, uneven cut, vibration, hard-to-pull starter rope, loss of drive), follow the diagnostic chart in the owner's manual.

Typical repair costs vs replacement (rule of thumb)

These ranges help you compare options for a gas walk-behind mower like model 917376545.

Scenario	What you usually replace	Typical value outcome
Poor cut or vibration	Blade, blade bolt, blade adapter hardware	Repair is usually cheaper
Mower will not self-propel	Drive belt, pulley, cable adjustments	Repair is usually cheaper
Wheels worn or damaged	Wheel and tire, dust covers, fasteners	Repair is usually cheaper
Major drive failure	Transmission assembly	Depends on mower age and labor cost
Major engine damage	Internal engine components	Replacement is usually cheaper

Parts that commonly make repair worthwhile

If your issue matches one of these, repairing is typically straightforward and economical:

• Replace a worn or bent blade with the husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825.
• Fix self-propel problems by inspecting the lawn mower ground drive belt 532196853 and related pulleys.
• Restore traction or stability with the lawn mower wheel and tire, 8 x 1.75-in 583719501.
• Replace broken safety and discharge components such as the lawn mower clipping deflector 532426129.

Why it matters

A mower that is cutting poorly, vibrating, or losing drive often needs routine wear parts, not a full replacement. Addressing those issues early helps prevent secondary damage (like deck wear, belt failure, or crankshaft stress) and keeps your Craftsman 917376545 mowing safely and evenly.

Common problems on the Craftsman 917376545 gas walk-behind mower include no-start conditions (stale fuel, dirty air filter, bad spark plug, fuel valve OFF), loss of power from grass buildup under the deck, poor or uneven cutting from a worn or bent blade, and drive issues from belt or cable wear. See the owner's manual troubleshooting chart for model-specific checks.

Most common symptoms and what usually causes them

• Won’t start: out of fuel, stale fuel, dirty air filter, spark plug wire off, bad spark plug, control bar not held to the handle, fuel valve lever in OFF (if equipped)
• Loss of power: cutting too much grass at once, dirty air filter, grass and debris packed under the mower housing, oil level too high
• Poor or uneven cut: worn or bent blade, loose blade bolt, wheels set at different heights
• Excessive vibration: bent or loose blade, damaged blade adapter, bent crankshaft
• Hard to push: grass too tall, cutting height too low, grass catcher too full, handle height not set comfortably
• Loss of drive or slowing (self-propelled): belt wear, belt off pulley, drive cable worn or broken, loose drive control system

Quick checks we recommend first (fastest wins)

1. Set the mower on a flat surface; confirm the control bar is held against the handle while starting.
2. Verify fresh gasoline; drain and refill if fuel is old or contaminated.
3. Check the fuel valve lever is ON (if your mower has one).
4. Inspect and clean or replace the air filter.
5. Look under the deck (spark plug wire disconnected first) and remove packed grass.

Parts that commonly fix cutting and vibration complaints

If the mower is leaving ragged grass tips, scalping, or shaking, the blade and related hardware are the first place we look.

Symptom	Most likely fix	Example part for this model
Uneven cut, torn grass	Replace a worn/bent blade	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Discharge not controlled	Replace damaged deflector	Lawn mower clipping deflector 532426129
Drive slows or slips	Inspect belt and pulleys	Lawn mower ground drive belt 532196853

Why it matters

Running with stale fuel, a clogged air filter, or heavy grass buildup under the deck overloads the engine and reduces airflow. A worn blade also forces the engine to work harder and can cause vibration that damages fasteners and deck components over time.

Most gas-powered walk-behind mowers, including the Craftsman model 917376545, typically last 8 to 10 years with normal residential use and routine maintenance. Consistent blade care, cleaning, and seasonal service are what most often determine whether you land closer to 8 years or push past 10.

What affects mower lifespan the most

• Maintenance frequency: oil changes, air filter service, and spark plug replacement
• Deck and blade condition: impacts, bending, and running with a dull blade
• Cleaning habits: built-up grass and debris under the deck and around the engine
• Fuel quality and storage: stale fuel and off-season storage practices
• Wear parts: wheels, belts, and drive components on self-propelled models

Maintenance milestones that extend life

Your manual calls out several practices that directly protect engine life and performance.

• Clean after each use: scrape grass buildup from the underside of the deck
• Avoid water intrusion: if you rinse, keep water away from the muffler, air filter, and carburetor
• Spark plug interval: replace at the start of each mowing season or every 100 hours (whichever comes first)
• Inspect muffler: replace if corroded to prevent overheating and damage
• After striking an object: stop, inspect, and repair before restarting

Reference steps and intervals in the owner's manual.

Quick “replace vs. repair” guide

What you’re seeing	What it usually means	Typical next step
Starts and runs well, cuts poorly	Blade is dull/bent	Sharpen or replace the blade
Engine runs hot, power drops	Debris buildup, restricted airflow	Clean deck and engine area
Self-propel won’t pull consistently	Drive belt or transmission wear	Inspect belt and drive system
Excess vibration after impact	Blade damage or loose hardware	Inspect blade and mounting

Common parts that wear before the mower is “worn out”

Replacing normal wear items often restores performance and helps you get the full lifespan.

• Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
• Lawn mower ground drive belt 532196853
• Lawn mower transmission assembly 589600601
• Lawn mower wheel and tire, 8 x 1.75-in 583719501

Why it matters

A mower that is cleaned regularly and kept in tune runs cooler, cuts with less strain, and avoids the accelerated engine wear that shortens lifespan. Good storage habits also prevent fuel and corrosion problems that can end a mower’s service life early.
