Craftsman 917370681 lawn mower Parts

Yes. For a Craftsman walk-behind mower like model 917370681, you can use gasoline with up to 10% ethanol (E10). Avoid fuel blends higher than 10% ethanol because they can pull in moisture, run lean, and accelerate wear in the carburetor and fuel system.

What fuel to use (and what to avoid)

• Use fresh, unleaded gasoline with 10% ethanol or less.
• Avoid E15, E20, E85 or any “flex fuel” blends.
• Avoid old gas; fuel that sits can cause hard starting and surging.
• If you store fuel, use a stabilizer and rotate it regularly.
• Keep the gas can sealed to reduce water contamination.

Quick checklist if the mower runs rough after E10

• Drain and replace old fuel with fresh E10.
• Check the air filter and replace if dirty.
• Inspect the spark plug; replace if fouled.
• Clean the deck to reduce load on the engine.
• If it still surges or won’t idle, the carburetor may need cleaning.

Typical fuel blend comparison

Fuel blend	Common label	Recommended for 917370681?	Why
0% ethanol	“E0”	Yes	Best for storage and consistent running
10% ethanol	“E10”	Yes	Common pump gas; works when fresh
15% ethanol	“E15”	No	Higher moisture risk; can cause running issues
85% ethanol	“E85”	No	Not compatible with small-engine fuel systems

Why it matters

Small engines on walk-behind mowers are sensitive to fuel quality. Higher-ethanol blends can separate in the tank, attract water, and leave varnish deposits that clog jets and passages, leading to hard starting, stalling, or loss of power.

For model-specific operating and storage guidance, follow the fuel and maintenance sections in the owner's manual.

Craftsman model 917370681 is a model number, not a date code, so it does not directly tell you the mower’s year. To identify the year, we use the mower’s product identification label (often showing a serial number or date code) and decode that information using the owner's manual.

Where to find the build date information

On most Craftsman walk-behind mowers, the date-related info is on the product label located in one of these common spots:

• Rear of the deck near the discharge opening
• Top of the deck near the engine mounting area
• Back of the mower near the height adjusters
• Handle bracket area (near where the handle bolts to the deck)

How to decode it (what to look for)

Once you find the label, look for a serial number or a date code. Common formats include:

• MMDDYY (month, day, year)
• YYMMDD (year, month, day)
• A longer serial number where the first 6 digits represent a date

Quick examples

Code format	Example	What it means
MMDDYY	072811	July 28, 2011
YYMMDD	110728	July 28, 2011

Why it matters

Knowing the build year helps us match the correct Craftsman parts and diagrams for wear items like the blade, wheels, and drive system. For example, if you are servicing the cutting system, matching the correct 22-inch blade style is key (see husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825).

If your Craftsman 917370681 self-propelled mower pulls to one side, the most common causes are uneven wheel traction (tire pressure, worn wheel tread, or a dragging wheel) or a drive system issue on one side (cable adjustment, pawl/pinion wear). Start with the wheels because they are the fastest checks.

Quick checks that fix most “pulling” problems

• Check tire pressure and inflate both drive wheels evenly.
• Inspect both rear wheels for uneven tread wear, wobble, or binding.
• Clean packed grass and debris from around the wheels and axle ends.
• Verify the mower rolls straight with the drive disengaged.
• Confirm the drive control fully releases when you let go.

Drive-side causes (when tire pressure is fine)

On many walk-behind self-propelled mowers, one wheel can stop driving as strongly if the wheel drive parts are worn or slipping.

Common culprits:

• Worn wheel and tire: replace the affected wheel if tread is smooth or the hub is damaged (use the correct size wheel such as lawn mower wheel and tire, 8 x 1.75-in 583719501).
• Worn drive pawl or gear: a slipping pawl can make one side “freewheel” under load (check drive pawl 532404845 and the mating gear such as pinion.14.te 532403849).
• Drive cable out of adjustment or stretched: if the cable does not pull the transmission engagement fully, drive can be uneven side-to-side (inspect lawn mower drive cable 586638001 routing and condition).

A simple test to pinpoint the side

Test	What to do	What it means
Push test (drive off)	Push mower on flat ground	If it still pulls, a wheel is dragging or misaligned
Lift-and-spin test	Lift rear; spin each wheel by hand	The “hard to spin” side is binding or rubbing
Drive test (light load)	Engage drive on pavement	If one wheel lags, suspect pawl/pinion/cable on that side

Why it matters

A mower that pulls to one side is harder to control and can accelerate wear on the transmission, wheels, and drive components. Fixing traction or a slipping drive part restores straight tracking and consistent self-propelled speed.

Model-specific reference

For control locations, drive engagement checks, and any adjustment procedure used on the Craftsman 917370681, follow the diagrams and operating steps in the owner's manual.

Common problems on the Craftsman 917370681 gas walk-behind mower are no-start conditions (fuel, spark, air), poor cutting (dull or damaged blade, deck clogging), and self-propel issues (cable, drive parts, transmission). We recommend starting with quick safety and maintenance checks from the owner's manual.

Most common symptoms and what usually causes them

• Won't start or starts then dies: stale fuel, dirty carburetor, fouled spark plug, clogged air filter
• Hard to pull the starter rope: blade obstruction, debris jammed under the deck, engine hydro-locked from overfilling oil
• Cuts unevenly or leaves strips: dull/bent blade, blade installed incorrectly, deck packed with wet grass
• Excess vibration: bent blade, loose blade hardware, damaged crankshaft (after impact)
• Self-propel won't move or slips: stretched/broken drive cable, worn drive wheel components, transmission wear

Quick checks we use first (fast, high success)

1. Disconnect the spark plug wire before working near the blade.
2. Tip the mower with the air filter and carburetor side up (prevents fuel/oil flooding).
3. Check fuel freshness; drain old fuel if it smells sour or looks dark.
4. Inspect the underside of the deck for packed grass and sticks.
5. Check the blade for damage; replace if bent or badly nicked.

Parts that commonly solve these issues on model 917370681

Problem	Common fix	Example part on this model
Poor cut, vibration, scalping	Replace blade	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Self-propel weak or not engaging	Inspect/adjust/replace drive cable	Lawn mower drive cable 586638001
Mower pulls to one side, drive traction issues	Replace worn wheel/tire	Lawn mower wheel and tire, 8 x 1.75-in 583719501
Discharge/mulch performance problems	Repair chute/door hardware	Lawn mower clipping deflector 532426129

Why it matters

Catching small issues early (like a dull blade or stretched cable) prevents bigger failures, improves cut quality, and reduces strain on the engine and drive system.
