Craftsman 917376403 lawn mower Parts

The model number for this Craftsman walk-behind lawn mower is 917.376403 (often written without the dot as 917376403). You’ll see it printed on the mower’s model tag and on the cover page of the 917376403 owner's manual.

Where to find the model number on the mower

We recommend checking 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
• Near the rear wheel height adjuster area
• On a sticker or metal plate that also lists engine details

Why the dot matters (917.376403 vs 917376403)

Both formats refer to the same mower; the dot is just a formatting style used on some labels and manuals.

What to use when ordering parts

For the most accurate parts match, we use the mower model number plus the exact part ID from the parts list.

• Use 917376403 as the model number
• Match the part by description and part ID (example: husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825)
• Confirm fit by comparing the diagram and key number in the manual parts list

Why it matters

Using the exact model number prevents ordering the wrong blade, wheel, cable assembly, or transmission parts, especially on 22-inch multi-cut decks where similar Craftsman models can use different hardware.

The most common problems we see on the Craftsman 917376403 walk-behind gas mower are poor cutting performance, drive/self-propel issues, and discharge or bagging problems. These usually trace back to normal wear items like the blade and blade adapter, or to linkage/cable and wheel-drive components.

Common symptoms and what they usually mean

• Cuts unevenly or leaves strips: dull/bent blade, loose blade hardware, worn blade adapter, deck buildup
• Vibrates excessively: bent blade, damaged blade adapter, loose fasteners
• Self-propel won’t pull or slips: worn drive parts (wheel/pinion/pawl), belt or transmission wear (if equipped)
• Poor bagging or clumping: clogged deck, incorrect mowing height, discharge door/deflector not moving freely
• Discharge chute won’t stay closed or opens poorly: weak/broken chute door springs

Quick checks we recommend first (safe, fast)

1. Shut the engine off, let it cool, and disconnect the spark plug wire.
2. Tip the mower safely (air filter and carburetor up) and inspect the blade and adapter.
3. Check that the discharge door moves freely and returns closed.
4. Inspect wheels for wobble, missing retainers, or worn gear teeth.
5. Confirm cables and handle controls move smoothly without binding.

Parts that commonly solve these issues on model 917376403

Symptom	Likely part to inspect/replace	Example from this model’s parts
Poor cut, tearing grass	Blade	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Vibration, blade won’t stay tight	Blade adapter	Blade adapter 581473301
Door won’t close/open correctly	Chute door springs	Husqvarna lawn mower discharge chute door spring, right 532419948 and husqvarna lawn mower discharge chute door spring, left 532419949
Self-propel slips/clicks	Wheel drive parts	Drive pawl 532404845 or pinion.14.te 532403849
Wheel wobble/drag	Wheel/tire	Lawn mower wheel and tire, 8 x 1.75-in 583719501

Why it matters

Addressing these wear items early improves cut quality, reduces vibration that can damage the crankshaft area, and restores traction so the mower moves consistently under load.

For model-specific maintenance intervals, control adjustments, and safe tipping/cleaning steps, follow the 917376403 owner’s manual.

A Craftsman walk-behind mower like model 917376403 typically lasts 8 to 12 years with normal residential use and basic maintenance. Blade care, clean oil, and keeping the deck clean make the biggest difference in how long the engine and drive system stay reliable.

Typical lifespan by use and care

• Light use (small yard, weekly mowing): 10 to 12 years
• Average use (mixed conditions): 8 to 10 years
• Heavy use (tough grass, dusty conditions, frequent bagging): 6 to 8 years
• Poor maintenance (old fuel, infrequent oil changes): 3 to 6 years

Maintenance that extends mower life

Use the maintenance schedule and specs in the owner's manual for model 917376403. These steps deliver the most value:

• Change engine oil on schedule; check level before mowing
• Use fresh fuel and stabilize fuel for storage
• Clean grass buildup under the deck after mowing (once cooled)
• Sharpen or replace the blade when cut quality drops
• Inspect wheels, drive components, and cables for wear and looseness

Parts that commonly affect “end of life” decisions

When a mower feels worn out, it is often a few service parts causing the problem rather than the whole machine.

Symptom	Common wear area	Example part on this model
Ragged cut, vibration	Blade or blade mounting	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Weak self-propel or slipping	Transmission/drive system	Lawn mower transmission assembly 589600601
Poor bagging or blowout	Rear skirt, deflectors	Husqvarna lawn mower rear skirt 532429157

Why it matters

Knowing the expected lifespan helps you decide whether to tune up (blade, drive, deck cleanup) or invest in bigger repairs. On model 917376403, restoring cut quality and drive performance often makes the mower feel “new” again for a fraction of replacement cost.
