Craftsman 944364152 gas lawn mower Parts

A “Craftsman 6.75” label by itself is not a model number; it typically refers to the engine power class. For this Craftsman walk-behind mower, the model number is 944364152, shown on the mower’s model decal and in the 944364152 owner's manual.

Where to find the model number on the mower

We use the model number to match the correct blade, wheels, and hardware for your exact deck and handle setup.

• Look for a model/serial decal on the rear of the mower housing (near the back of the deck)
• Write down both the model number and serial number
• Use the full model number exactly as printed (for this unit: 944364152)
• If the decal is dirty or faded, wipe it clean and use a flashlight at an angle

Why “6.75” is not enough

“6.75” is commonly used to describe an engine family or power rating, and multiple Craftsman mowers can share that same marking while using different decks, blades, and controls.

What “6.75” usually refers to vs what you need

Marking you see	What it identifies	What we use for parts lookup
6.75	Engine power class (not unique)	Model number (unique)
160cc	Engine displacement (not unique)	Model number + serial
21"	Deck size category (not unique)	Model number

Parts that depend on the correct model number

Once you confirm 944364152, you can confidently match common wear items and fasteners.

• Cutting system parts like the lawn mower blade 532406712
• Blade mounting parts like the husqvarna lawn mower blade adapter 532418373
• Deck and discharge parts like the discharge guard 589482402
• Hardware such as the lawn mower hex flange nut 532409149

Why it matters

Using the correct model number prevents ordering a blade or adapter that does not fit the crankshaft pattern or deck design, and it helps ensure safe operation and proper cutting performance.

Common problems on the Craftsman 944364152 gas walk-behind mower include no-start conditions (often fuel, spark, or control-bar related), loss of power from airflow or deck buildup, poor cut from a worn or loose blade, and excessive vibration from blade or adapter issues. Our 944364152 owner's manual troubleshooting chart matches these symptoms closely.

Most common symptoms and what usually causes them

• Won’t start: control bar not held to the handle, fuel valve OFF (if equipped), weak/disconnected battery (if equipped), loose blade, or a broken blade adapter
• Loss of power: dirty air filter, cutting height too low, grass/debris buildup under the deck, oil level too high, walking speed too fast
• Poor cut (uneven): worn/bent/loose blade, wheels set at different heights, deck packed with clippings
• Excessive vibration: worn/bent/loose blade, damaged blade adapter, bent crankshaft
• Hard to pull starter rope: control bar released (brake engaged), blade dragging in grass, blade adapter problem

Quick checks we recommend (in order)

1. Safety/control: Hold the control bar firmly against the handle before pulling the rope.
2. Fuel and oil: Use fresh fuel; verify oil is at the correct level (not overfilled).
3. Airflow: Clean or replace the air filter if it’s dirty.
4. Deck condition: Tip the mower with the air filter and carburetor facing up; clean packed grass from the underside.
5. Blade and hardware: Inspect the blade and mounting. Replace a damaged blade and tighten the blade bolt.

Parts that commonly solve these issues

Symptom	Part to inspect/replace	Example from this model’s parts list
Poor cut, vibration	Blade	Lawn mower blade 532406712
Vibration, blade won’t stay tight	Blade adapter	Husqvarna lawn mower blade adapter 532418373
Hard to push, uneven height	Wheel/height hardware	Lawn mower wheel 532433121 and husqvarna lawn mower height adjuster knob 532701037

Why it matters

These problems usually share the same root causes: restricted airflow (dirty filter), restricted discharge (deck buildup), or an out-of-balance cutting system (blade or blade adapter). Fixing them early improves cut quality, reduces vibration, and helps protect the engine and deck.

On the Craftsman 944364152 gas walk-behind mower, the engine system is made up of the fuel and air delivery parts plus the ignition and starting parts that make it run. Common engine-related components include the air filter, spark plug, starter handle, muffler, and fuel fill/cap (see the 944364152 owner's manual).

Main engine-related parts (what they do)

These are the most common “engine parts” customers mean when troubleshooting starting, power, or rough running:

• Air filter: keeps dirt out of the engine; a clogged filter can cause hard starting and loss of power.
• Spark plug: ignites the fuel-air mixture; a worn or fouled plug can cause misfires or no-start.
• Starter handle (recoil starter): spins the engine fast enough to start.
• Muffler: reduces exhaust noise; damage or blockage can affect performance.
• Fuel system parts (fuel tank, fuel cap, fuel line, carburetor): store and meter gasoline to the engine.
• Ignition system parts (ignition coil, flywheel): create spark at the right time.

What’s “engine” vs “mower” parts?

Some parts are often confused with engine parts because they affect operation, but they are part of the mower’s cutting or safety systems.

Category	Examples	Why you care
Engine system	air filter, spark plug, carburetor, muffler, recoil starter	Drives starting, power, and smooth running
Cutting and deck system	blade, blade adapter, discharge guard, mulcher door	Affects cut quality, vibration, and discharge/bagging
Operator control and safety	zone control cable, operator presence control bar	Engine runs only when controls are held correctly

Parts on this model that are commonly replaced

If you are chasing vibration, poor cut, or discharge issues (often blamed on the engine), these model-matched parts are frequent fixes:

• Lawn mower blade 532406712
• Husqvarna lawn mower blade adapter 532418373
• Discharge guard 589482402
• Husqvarna lawn mower zone control cable 532440934

Why it matters

Correctly separating engine problems (fuel, spark, air) from deck/control problems (blade, adapter, discharge, zone control) saves time and prevents replacing the wrong parts.

You can order model-specific replacement parts from the parts list for your mower, or search by model number on Sears PartsDirect.
