Craftsman 917273221 tractor Parts

On the Craftsman tractor model 917273221, the engine is a Kohler CV22S and it uses the same core engine systems found on most riding lawn tractors: fuel, ignition/charging, starting, lubrication, exhaust, and rotating internal components (like the crankshaft). For diagrams and exact part callouts, use the 917273221 owner's manual.

Main engine systems and what they include

Most tractor engines are built from these groups of parts:

• Fuel system: fuel tank, fuel line, carburetor and gaskets, hose clamps
• Ignition/charging: flywheel, rectifier-regulator, key, connectors
• Starting system: starter motor, drive kit, brush kit, armature
• Lubrication: oil pan and related seals/hardware
• Exhaust: exhaust gaskets, studs, muffler and guard
• Rotating assembly: crankshaft and related plugs

Common engine-related parts you will see on model 917273221

Your manual’s engine breakdown for model 917273221 lists several tractor-level engine parts (items mounted to or supporting the engine), including:

• Fuel tank and fuel tank stem
• Throttle control and choke control
• Electric clutch (PTO drive)
• Muffler and muffler guard
• Idler pulley and belt keeper hardware

If you are troubleshooting blade engagement, the switch.pto.3 582107601 is the operator control that engages the mower deck attachment clutch.

Quick reference: “internal engine” vs “tractor-mounted engine parts”

Category	Examples	What it affects
Internal engine parts	crankshaft, carburetor kit, exhaust gasket	Starting, power, fuel delivery
Tractor-mounted engine parts	fuel tank, throttle control, electric clutch	Operation, blade engagement, drivability

Why it matters

Knowing which system a part belongs to speeds up diagnosis. For example, a no-start often points to fuel delivery or ignition/starting parts, while “blades will not engage” often points to the PTO switch, wiring, or electric clutch.

For Craftsman model 917273221, the owner's manual identifies it as a 24.0 HP, electric-start, front-engine garden tractor with a 50-inch mower. For the exact engine manufacturer and engine model number, use the identification section in the 917273221 owner's manual.

What we can confirm for model 917273221

From the manual for this specific Craftsman tractor, we can rely on these model-specific details:

• 24.0 HP engine rating
• Electric start
• Front-engine riding tractor design
• 50-inch mower/deck size
• Uses unleaded regular gasoline (3.5-gallon capacity)
• Uses SAE 10W-30 oil above 32°F and SAE 5W-30 below 32°F

How to identify the exact engine brand and model

Many Craftsman tractors use engines from common small-engine manufacturers, but the sure match is the engine ID label on your tractor.

• Look for an engine data tag on the engine shroud, valve cover area, or blower housing
• Record the engine model, type, and code/spec numbers
• Match those numbers to the engine parts list and tune-up specs in the 917273221 owner's manual
• If the tractor cranks but will not start, check ignition and safety circuits before assuming an engine failure

Quick ID checklist

What to record	Where you use it	Why it matters
Engine model/type/code	Engine parts lookup	Ensures correct filters, plugs, and gaskets
Tractor model 917273221	Tractor parts lookup	Ensures correct belts, deck parts, and controls
Fuel and oil specs	Maintenance	Prevents hard starting and engine wear

Why it matters

The engine brand and exact model determine the correct spark plug, air filter, oil filter, and tune-up procedure. Using the wrong maintenance parts can cause hard starting, poor power, and reduced battery charging.

The Craftsman tractor model 917273221 uses a Kohler engine model CV22S with type number 75518. This engine identification is listed in the engine breakdown for tractor model 917273221 in the 917273221 owner's manual.

How to confirm the engine model on the tractor

We recommend verifying the ID directly on the engine tag so you can match the correct Kohler parts (especially ignition and charging components).

• Locate the Kohler ID label on the blower housing or near the starter
• Wipe off dirt and oil so the stamping is readable
• Record the model and type exactly as shown
• Use the type number when ordering carburetor, ignition, or charging parts
• Use the tractor model 917273221 when ordering chassis, deck, and steering parts

Engine ID vs. tractor model number

ID you’re looking for	What it identifies	What you’ll see for this tractor
Tractor model number	Craftsman chassis and deck	917273221
Engine model number	Kohler engine family	CV22S
Engine type number	Exact Kohler build spec	75518

Why it matters

Kohler engines often share the same model number but use different internal specs by type number. Using CV22S-75518 prevents ordering the wrong ignition module, regulator-rectifier, or fuel system parts.

Related parts that can affect starting and PTO operation

These are common tractor-side parts (not engine-internal) that can cause no-start or PTO issues:

• Switch.pto.3 582107601 (PTO switch)
• Molded ignition key 532140403 (ignition key)
• Husqvarna lawn tractor fuel tank 532151346 (fuel tank)

Craftsman model 917273221 is a specific front-engine lawn tractor model number, but the model number alone does not define a single “model year.” The most accurate way to date your tractor is to use the serial/date information on the tractor’s ID tag and confirm it against the parts lists in the 917273221 owner's manual.

How to find the build date on the tractor

Use the tractor’s identification tag first; it is the only reliable way to tie your exact unit to a production date.

• Locate the model/serial tag (commonly under the seat, on the frame rail, or near the rear fender pan)
• Write down the serial number exactly (include all letters and numbers)
• Look for a date code or manufacture date printed on the tag
• If the tag is missing, check for a sticker on the engine (engine date is helpful but not the tractor build date)
• Compare major assemblies (deck, steering, electrical) to the diagrams in the manual

Use the manual to confirm you have the right version

The parts lists and diagrams in the manual help confirm you are matching the correct configuration for 917273221.

What you’re checking	Where to verify	Why it matters
Model number format	ID tag and manual cover/headers	Confirms you are using the correct documentation
Electrical components	Manual electrical section	Helps match harness, switches, and key style
Steering and deck layouts	Manual diagrams	Confirms the correct chassis and deck family

If you are troubleshooting starting or electrical issues while you’re identifying the tractor, the molded ignition key 532140403 is a common model-matched item shown in the electrical parts list.

Why it matters

The correct production date and configuration prevent ordering the wrong Craftsman parts, especially for mower deck, steering, and electrical components where small design changes affect fit.

On the Craftsman lawn tractor model 917273221, the most reliable “date” information is typically found on the engine data label and on component labels (especially the battery). Use the locations and label diagrams in the 917273221 owner's manual to identify the exact decal or tag positions on your tractor.

Common places to check on a riding lawn tractor

Look for a printed label, stamped tag, or decal with a date code, serial number, or manufacturing code in these areas:

• Under the hood near the engine shroud or blower housing (engine label)
• On the frame rail near the seat, footrest, or steering column
• Near the battery tray or on top/side of the battery case
• On the underside of the hood or near dash decals
• On the rear fender pan or near the transaxle area

Battery and charger date codes (if equipped)

If you are checking a Craftsman battery or charger date code, the code is usually on the battery housing (often on top) or on the bottom of the charger. Many date codes are numeric and may be formatted as a short string (often 6 digits).

Quick label check steps

• Wipe dirt and oil off the label area so the code is readable.
• Use a flashlight and take a photo; zooming in often reveals faint stamping.
• Write down the full code exactly as shown (include letters).
• Compare the code to any “serial” or “model” fields on the same label.

What you might see (and what it means)

Marking on label	What it usually indicates	Where it’s commonly found
Serial number	Unit identification	Frame tag, dash area
Date code	Manufacturing date or batch	Battery, charger, some components
Engine model/type code	Engine build info	Engine shroud label

Why it matters

The product date code helps us match the correct replacement parts (like an ignition key, PTO switch, or belts) and confirm compatibility when a model has mid-year production changes.
