Craftsman 917273372 lawn tractor Parts

To find your Craftsman mower model number, look for the model/serial label on the tractor frame, usually under the seat or near the rear fender area. For this Craftsman lawn tractor, the model number is 917.273372 (often shown as 917273372 on parts pages); confirm the exact characters in the 917273372 owner's manual.

Where to look on a Craftsman riding mower

Check these common label locations first (clean off grass and oil so you can read it):

• Under the seat pan or on the seat support
• On the rear fender or rear frame area
• On the frame rail near the engine compartment
• Near the steering column or dash support
• On the mower deck shell (less common for the main tractor model)

What numbers you should write down

For ordering the right parts (blades, V-belt, mandrel parts, steering parts), record:

• Model number (example: 917273372)
• Product number (if listed)
• Serial number
• Engine model/type/code (engine parts often use engine ID, not tractor ID)

Quick check: model number vs. engine number

You need parts for	Use this ID	Example
Mower deck, belts, steering, chassis	Tractor model number	917273372
Carburetor, starter, ignition coil, engine gaskets	Engine model/type/code	Listed on engine shroud

Why it matters

Craftsman tractors can look similar across years, but small differences (deck style, belt length, mandrel design) change the exact replacement part. Using the correct model number helps match parts like the lawn tractor 42-in deck high-lift blade 532138971 or the v-belt 532138255 to your specific deck and drive setup.

The Craftsman lawn tractor model 917273372 uses a 17.5 HP gas engine (single-cylinder) and is designed to run at full throttle for best cutting and battery charging performance. For the exact engine details and specifications, follow the identification steps in the 917273372 owner's manual.

How to identify the exact engine on your tractor

Use these quick checks to match the engine to the correct tune-up and repair parts:

• Look for the engine model/type code label on the blower housing, valve cover, or near the starter
• Record the engine model number and type (and code/serial if shown)

• Verify the tractor model tag shows 917273372
• If the label is dirty, wipe it clean; do not scrape off printed numbers

What we can confirm for model 917273372

From the owner’s manual, this tractor is a 17.5 HP, 42-inch mower deck, electric-start unit with a 6-speed transaxle. That narrows the engine class and helps you choose the right maintenance parts (spark plug, air filter, fuel filter, oil).

Common engine-related symptoms and where to start

If you are troubleshooting starting or performance issues, these checks solve most problems:

• Battery charge and cable connections
• Fresh fuel and open fuel shutoff (if equipped)
• Clean air filter and correct oil level
• Safety interlock operation (seat, brake, PTO)
• Starter solenoid click vs. crank behavior

Symptom	Most likely area	Best first action
Clicks but won’t crank	Battery, cables, solenoid	Load-test battery; clean terminals
Cranks but won’t start	Fuel, spark, air	Check fuel freshness; inspect plug
Runs rough under load	Air filter, blade/deck drag	Clean filter; check deck for buildup

Why it matters

The exact engine model number determines the correct spark plug, air filter, and oil type/quantity. Using the wrong tune-up parts can cause hard starting, poor mowing power, and faster wear.
