What model number is the Craftsman 917377941?
The model number is 917.377941 (often written without the dot as 917377941) for this Craftsman rotary lawn mower. You can confirm it on the identification label and in the owner's manual for the mower.
Most Craftsman walk-behind mowers list the model number on a product label located on the deck or rear housing area.
- Check the rear of the mower deck near the discharge or bagging area
- Look around the engine mounting area on the deck
- Wipe dirt and grass residue off the label so the full number is readable
- Record the full model number exactly as shown (including any dot)
Both formats typically refer to the same mower; the dot is a formatting style used in manuals and labels.
| You see this | What it means for parts lookup |
|---|---|
| 917.377941 | Same model; manual-style formatting |
| 917377941 | Same model; common online lookup format |
Using the exact model number helps us match the correct diagrams and parts for your Craftsman rotary lawn mower, especially for drive and bagging components.
Common examples on this model include:
- Drive system parts like the lawn mower drive control lever 532425662
- Rear wheel and traction components
- Grass bag and door hardware
- Blade mounting hardware (adapter, washers, lock nuts)
If your mower label is worn, use the parts list diagrams in the owner's manual to cross-check assemblies (handle, drive control, gear case, grass bag) against what you see on your mower.

How do I troubleshoot my 917377941?
To troubleshoot your Craftsman 917377941 walk-behind mower, start by identifying the symptom (won’t start, starts then dies, poor cut, or won’t self-propel) and check the simple items first: fuel, spark, airflow, and blade/deck condition. Use the 917377941 owner's manual for the correct control positions and adjustment points.
- Won’t start: stale fuel, spark plug/wire issue, safety control not held, clogged air filter
- Starts then dies: dirty carburetor, fuel cap vent issue, debris in fuel, choke not opening
- Poor cut or vibration: bent/dull blade, loose blade hardware, damaged blade adapter
- Won’t self-propel: drive cable out of adjustment, worn belt/pulley, transmission issue
- Safety first: disconnect the spark plug wire before inspecting the blade or underside.
- Fuel: drain old fuel and refill with fresh gasoline.
- Spark: confirm the plug wire is firmly seated; replace the spark plug if fouled.
- Airflow: clean or replace the air filter.
- Blade and adapter: inspect for damage; a worn adapter can cause slipping and vibration (this model uses a blade adapter style like lawn mower blade adapter 532186766).
- Self-propel drive: check cable tension and linkage movement; inspect pulleys for wobble or binding (an example drive pulley is the lawn mower idler pulley 532166043).
| Problem | What to inspect | Common fix |
|---|---|---|
| No start | fuel, spark plug, air filter | fresh fuel, new plug, clean filter |
| Runs rough | carburetor, choke, fuel flow | clean carburetor, clear fuel path |
| Vibrates | blade, blade adapter, fasteners | replace blade/adapter, tighten hardware |
| No drive | drive cable, pulleys, transmission | adjust cable, replace worn pulley/belt |
Systematic troubleshooting prevents unnecessary parts replacement and helps you focus on the highest-failure items first (fuel quality, ignition, airflow, and drive adjustments). The diagrams and procedures in the manual keep adjustments correct for the 917377941.

What is the average lifespan of 917377941?
A Craftsman rotary walk-behind mower like model 917377941 typically lasts 8 to 12 years with normal residential use and basic maintenance. Regular oil changes, clean air filtration, and keeping the deck and drive system adjusted are what most often determine whether it reaches the high end of that range.
- Engine maintenance: clean oil, clean air filter, fresh fuel
- Cutting load: tall, wet grass and frequent mulching increase strain
- Deck condition: corrosion and impact damage shorten life
- Drive system wear (self-propelled): belt, pulleys, transmission, and cables
- Storage: dry storage and off-season fuel care prevent hard-start issues
| System | Typical service life | What usually ends it |
|---|---|---|
| Engine | 8 to 12 years | neglected oil, dirty cooling fins, stale fuel |
| Deck and handle | 10+ years | rust-through, cracks, impact damage |
| Self-propel drive | 5 to 10 years | worn transmission, pulleys, stretched cables |
| Wheels and height adjust | 5 to 10 years | worn wheel hubs, bent adjusters |
- Change engine oil on schedule and keep the oil at the correct level.
- Use fresh gasoline; don’t store fuel in the tank for long periods.
- Keep the underside of the deck clean (after the mower is cool and the spark plug wire is disconnected).
- Inspect and tighten hardware; replace worn fasteners like a lock nut 532409149 when needed.
- Keep the drive controls adjusted so the mower drives without slipping or dragging.
Most “mower won’t start” and “won’t self-propel” complaints trace back to routine wear items and maintenance, not the mower being at end-of-life. Following the service intervals in the 917377941 owner's manual helps you avoid premature engine and drive failures.
