Craftsman 917388920 lawn mower Parts

A 48-inch walk-behind mower typically weighs about 300 to 600 lb, with commercial hydro-drive models landing toward the higher end. Your Craftsman 917388920 is a 21-inch walk-behind mower, so it weighs far less than a 48-inch unit; use the 917388920 owner's manual for the exact spec.

Typical weight range for a 48-inch walk-behind mower

Most 48-inch walk-behind mowers fall into a broad range because weight changes a lot by build and drive system:

• Lighter commercial gear-drive units: ~300 to 450 lb
• Commercial hydro-drive units: ~400 to 600 lb
• Add-ons (sulky, larger tank, guards): often add 10 to 50 lb

What affects weight the most

• Drive system: hydrostatic transmissions add significant weight versus gear-drive
• Deck construction: fabricated decks usually weigh more than stamped decks
• Engine size and starting system: larger engines and electric start add weight
• Frame and wheel/tire size: heavier-duty frames and larger tires increase total weight

Quick comparison

Mower type	Deck size	Typical weight	Best use
Residential walk-behind (like Craftsman 917388920)	21 in	Much lighter than 48 in	Home lawns
Commercial walk-behind	48 in	300 to 600 lb	Larger properties, frequent mowing

Why it matters

Weight determines what you need for loading ramps, trailer capacity, tie-down points, and turf impact. A heavier 48-inch commercial mower also needs more stable transport and storage planning.

The most common issues we see with the Craftsman 917388920 walk-behind gas mower are starting problems, poor cutting quality, and drive or control issues (cable and handle hardware). Many of these are caused by normal wear items, loose fasteners, or a blade and adapter that need service.

Common symptoms and what usually causes them

• Won’t start or starts then stalls: old fuel, dirty air filter, fouled spark plug, carburetor varnish, or a safety/control cable out of adjustment
• Cuts unevenly or leaves strips: dull/bent blade, loose blade hardware, worn blade adapter, deck packed with wet grass
• Excess vibration: bent blade, damaged blade adapter, loose nuts/bolts on the blade or handle
• Self-propel/drive feels weak (if equipped): cable stretch/misrouting, worn wheels, loose handle hardware
• Handle/control feels loose: worn knobs/bolts, missing clips, or loose fasteners

Quick checks we recommend first (safe, fast)

1. Turn the engine off and disconnect the spark plug wire.
2. Tip the mower with the air filter and carburetor side up (to reduce fuel/oil leakage).
3. Inspect the blade area for damage and tightness.
4. Check control cable routing and clamp points along the handle.
5. Confirm handle hardware is tight and the handle is aligned.

Parts that commonly wear on this model

These are frequently involved when the mower vibrates, cuts poorly, or controls feel off:

• Husqvarna lawn mower 21-in deck 3-in-1 blade 532189028
• Lawn mower blade adapter 581547901
• Walk-behind lawn mower engine cable 532176556
• Lawn mower wheel 532427026
• Handle bolt 532191574

Troubleshooting guide by symptom

Symptom	Most likely area	What to do
Rough cut/strips	Blade, adapter, deck	Sharpen/replace blade, inspect adapter, clean deck
Strong vibration	Blade, adapter, fasteners	Stop using, inspect for bends/cracks, tighten hardware
Control won’t hold	Cable, clamp, handle hardware	Check cable routing, clamp tension, replace worn hardware
Hard to push	Wheels/axle, deck drag	Check wheel wear, axle alignment, deck buildup

Why it matters

A worn blade or blade adapter can cause vibration that damages the deck and crankshaft over time. Keeping the blade tight, sharp, and properly mounted also improves cut quality and reduces strain on the engine.

For model-specific adjustment points, torque guidance, and diagrams, use the Craftsman 917388920 owner’s manual.

The model number is 917.388920 (commonly written without the dot as 917388920). This Craftsman walk-behind rotary lawn mower’s owner documentation and parts diagrams identify it as model 917.388920, so you can use 917388920 when ordering parts or looking up specs in the 917388920 owner's manual.

Where to find the model number on the mower

We recommend confirming the number on the mower’s ID label before ordering parts.

• Check the rear of the deck near the discharge area
• Look on the handle support area or upper handle mounting points
• Wipe off grass and dirt; the label can be hard to read when dirty
• Match the full model number exactly (including any dots on the label)

Why the dot matters (and when it does not)

On many Craftsman labels, the model is printed with a dot (917.388920), but parts sites and search fields often use the no-dot format (917388920). Both refer to the same mower.

You see this	Use this for searches/orders	Meaning
917.388920	917388920	Same model number, different formatting
917388920	917388920	Standard no-dot entry format

Helpful next steps for parts lookup

Once you confirm the model number, use the diagrams in the manual to identify the exact part and hardware.

• Use the exploded views in the 917388920 owner's manual to match part locations
• If you are replacing handle hardware, confirm the correct fastener type and size
• For common handle and control repairs, verify cable routing and clamp placement
• When replacing cutting components, inspect the blade adapter and blade mounting hardware

Example parts commonly referenced by the handle and control area

• Upper handle 532194179
• Walk-behind lawn mower engine cable 532176556

Why it matters

Using the exact model number 917388920 ensures you get the correct Craftsman walk-behind mower parts (like the control cable, handle components, and blade-related hardware) and avoids ordering parts for a similar 917-series mower.
