Craftsman 9174787A lawn mower Parts

On the Craftsman 9174787A walk-behind mower, the most common problems we see are poor cutting (uneven cut or vibration), loss of power, hard starting or a starter rope that’s hard to pull, and self-propel drive issues (hard to push, loss of drive, or slowing drive speed). Use the troubleshooting chart in the 9174787A owner's manual to match symptoms to the fastest fix.

Most common symptoms and what usually causes them

• Loss of power: heavy grass load, dirty air filter, grass buildup under the deck, oil level issues
• Poor cut or uneven cut: worn or bent blade, wheels set at different heights, deck packed with clippings
• Excessive vibration: loose or damaged blade, damaged blade adapter, bent crankshaft
• Starter rope hard to pull: control bar not held to the handle, blade dragging in grass, internal engine issue
• Hard to push or loss of drive (self-propel): debris in drive wheels, belt wear/off pulley, worn/broken drive cable

Quick checks you can do before buying parts

1. Tip the mower safely (spark plug wire disconnected) and clean the underside of the deck.
2. Confirm all wheel height adjusters are set the same.
3. Inspect the blade for bends, cracks, or heavy rounding.
4. Check that front drive wheels turn freely; clean grass and debris from the dust cover, pinion, and gear teeth.
5. Verify the control bar is fully depressed before pulling the starter rope.

Parts that commonly solve cutting and drive complaints

Symptom	Common fix	Example part for 9174787A
Uneven cut, vibration	Replace a worn/bent blade; tighten blade bolt	Husqvarna lawn mower 22-inch deck 3-in-1 blade 532421825
Loss of drive/slipping	Inspect belt and drive system; replace worn cable if needed	Lawn mower drive cable 586638001
Hard to push/self-propel weak	Clean drive wheel gears; replace worn wheel if needed	Lawn mower wheel and tire, 8 x 1.75-in 583719501

Why it matters

Most “big” mower problems start as simple maintenance issues: grass buildup under the deck reduces airflow and power, uneven wheel settings cause a poor cut, and packed drive wheels can make a self-propel mower feel like the transmission failed.

For your Craftsman lawn mower model 9174787A, use fresh unleaded gasoline; fuel with up to 10% ethanol (E10) is acceptable, and anything over 10% ethanol should be avoided. This helps protect the fuel system and prevents hard-start and performance problems.

Recommended fuel for model 9174787A

• Use fresh, clean unleaded gasoline from a busy station.
• E10 (up to 10% ethanol) is OK for this mower.
• Avoid E15, E20, E85, or any fuel labeled “more than 10% ethanol.”
• If the mower will sit, use a fuel stabilizer and rotate fuel often.
• Do not keep gasoline from one mowing season to the next.

Quick fuel guide

Fuel type at the pump	Ethanol content	Use in 9174787A?
Unleaded (often “E0” where available)	0%	Yes
Regular unleaded (E10)	Up to 10%	Yes
Unleaded 88 / E15	15%	No
Flex fuel (E85)	Up to 85%	No

Why it matters

Using the right gasoline reduces stale-fuel issues that commonly cause a mower to not start, run rough, or surge. Ethanol-heavy fuel also increases the chance of moisture-related fuel problems during storage.

Helpful tips for fewer fuel problems

• If you suspect stale fuel, drain the tank and refill with fresh gas.
• Store fuel in a clean, non-rusting gas can.
• Let the engine cool before storing the mower indoors.
• Follow the fuel and storage guidance in the 9174787A owner's manual.
• For off-season storage steps, use our how to winterize a lawn mower guide.

“6.75” on a Craftsman walk-behind mower typically refers to the engine series/horsepower class, not the mower’s model number. For the Craftsman mower covered by this page, the model number is 9174787A; you’ll also see it printed as 917.4787A in the 9174787A owner's manual.

Where to find the model number on the mower

We recommend confirming the model number from the mower’s ID label (not the engine shroud). Common places to check:

• Rear of the deck near the discharge opening
• On the back flap/rear skirt area
• Near the height adjuster brackets
• On the handle support area
• In the documentation that came with the mower

“6.75” vs. mower model number (quick comparison)

Marking you see	What it usually identifies	Example
6.75 / 675 Series	Engine family/series (often Briggs & Stratton)	“675 Series” on the engine cover
917.xxxxxxx	Craftsman mower model number	917.4787A
Engine model/type/code	Engine-specific ID for parts like carburetor, ignition, recoil	Stamped on the engine label

Why it matters

Using the correct mower model number (like 9174787A) helps us match the right walk-behind mower parts such as the blade, drive cable, and control cable. For example, this model uses parts like the lawn mower drive cable 586638001 and the lawn mower control cable 587326601 when those systems need service.

Tip for ordering the right parts

• Use the mower model number for deck, wheels, drive, and handle parts
• Use the engine model/type/code for engine parts (spark plug, carburetor, air filter)
• If your mower is self-propelled, confirm whether you need a drive cable vs. a zone control cable
