Craftsman 917387681 rotary lawn mower Parts

The most common repairs on the Craftsman 917387681 rotary lawn mower are basic tune-up and cutting-system fixes: addressing stale fuel, a dirty air filter, a worn or bent blade, grass buildup under the deck, and starter-rope issues. Many problems trace back to routine maintenance in the 917387681 owner's manual.

Most common repairs we see (and what to check first)

• Won’t start or runs rough: old fuel, fouled spark plug, dirty air filter
• Loss of power: grass/debris packed under the mower deck, cutting too much grass at once
• Poor cut or uneven cut: worn, bent, or loose blade; uneven wheel height settings
• Excessive vibration: loose or damaged blade, broken blade adapter, or bent crankshaft
• Starter rope hard to pull: blade dragging in grass, blade adapter issues, or brake engaged when the control bar is released

The Craftsman rotary lawn mower model 917387681 uses a 6.5 horsepower gas engine (as shown in the model’s documentation). For the most accurate engine identification (make, model, and tune-up specs), match the engine numbers on the engine shroud to the listings in the 917387681 owner's manual.

How to identify the exact engine on your mower

Even within the same mower model, the engine manufacturer and spec code can vary by production run. Use these checks:

• Look for the engine model, type, and code stamped on the blower housing or valve cover
• Record the full engine model number plus the spec/type code
• Compare those numbers to the engine section in the 917387681 owner's manual
• Use the engine numbers (not just the mower model) when buying a carburetor, air filter, or ignition parts
• If the starter rope area has a label, copy that label exactly before ordering parts

Where the manual helps most

The manual for model 917387681 calls out key engine-related items and operating features, including:

• Primer location and cold-start use
• Engine oil fill and dipstick location
• Spark plug location
• Operator presence control bar (engine zone control)

Quick reference: mower model vs. engine model

What you have	Where to find it	What it’s used for
Mower model 917387681	Mower deck tag or manual cover	Finding chassis parts like wheels and handles
Engine model/type/code	Stamped on the engine	Finding engine parts and tune-up specs

Why it matters

Ordering by mower model alone can lead to the wrong engine parts. Using the engine model/type/code ensures you get the correct spark plug, air filter, and carburetor parts for your exact 6.5 HP engine setup.
