Craftsman 917203930 tractor Parts

To look up your Craftsman riding mower model number, we check the ID label on the tractor itself first; on model 917203930, it’s typically on the frame under the seat or on the underside of the seat. Once you have the full model number, you can match the correct parts and diagrams.

Where to find the model number on a Craftsman tractor

Look for a sticker or metal tag with MODEL and SERIAL information:

• Under the seat on the frame rails (lift the seat up)
• On the underside of the seat pan
• Near the rear fender area close to the seat mount
• On the frame near the engine compartment (less common)
• Wipe dirt and grass off the label so every digit is readable

How to use the model number to find the right parts

After you locate the model number, use it exactly as printed (all digits matter).

What you have	What it’s used for	Tip
Model number (example: 917203930)	Finds the correct parts diagrams and part list	Enter all digits, no spaces
Serial number	Identifies production run details	Helpful when parts changed mid-series
Product name (Craftsman lawn tractor)	General browsing only	Not specific enough for ordering

If the label is missing or unreadable

Use these practical workarounds to narrow it down:

• Check your purchase receipt or owner paperwork
• Look for the engine model on the engine shroud (engine parts differ from tractor parts)
• Compare your deck and steering parts to diagrams once you’re close
• If you’re replacing a known deck component, match by assembly style (for example, a mandrel housing)

If you’re working on the mower deck, the lawn tractor mandrel housing 587819701 is a common part customers identify visually to confirm they’re in the right deck diagram.

Why it matters

Craftsman tractors often share similar looks across multiple model numbers; using the exact model number prevents ordering the wrong belt, steering link, PTO switch, or deck hardware.

For model-specific identification notes and labeling locations, use the 917203930 owner's manual.

Common problems on a Craftsman riding mower like model 917203930 are no-start or hard-start conditions, weak or no crank, poor cutting quality, and drive or deck issues caused by worn belts, dirty fuel/air components, or safety switch and wiring faults. Use the 917203930 owner's manual to match symptoms to the correct checks and adjustments.

Most common symptoms and what usually causes them

• Engine clicks but will not crank: weak battery, corroded battery cables, bad solenoid, safety interlock issue
• Cranks but will not start: stale fuel, clogged carburetor jets, fouled spark plug, restricted air filter
• Starts then dies (especially when releasing brake): brake/clutch safety switch out of adjustment, fuel delivery restriction
• Mows unevenly or leaves strips: deck out of level, dull blades, bent deck components, worn mandrel bearings
• Deck will not engage: PTO switch problem, electric clutch issue, belt routing/tension problem
• Poor drive or slipping: worn ground drive belt, idler pulley wear, linkage out of adjustment

Quick checks we recommend first (fast, high success rate)

1. Verify the operator presence and brake/clutch safety switches are being fully actuated.
2. Inspect battery terminals for corrosion and confirm tight connections.
3. Drain old fuel and refill with fresh fuel; replace/clean the air filter.
4. Check the deck and ground drive belts for glazing, cracking, or slack.
5. Look for loose wiring at the ignition switch area and at the solenoid.

Parts that commonly fix these problems on 917203930

Symptom	Common suspect part	Example from this model’s parts
Clicks but no crank	Starter solenoid	Lawn tractor starter solenoid 582042802
Deck will not engage	PTO switch	Switch.pto 582107601
Slipping drive or weak deck spin	Worn belt	Husqvarna lawn tractor belt, 1/2 x 101-1/6-in 592855001
Rough cut, vibration	Worn mandrel/bearing	Lawn tractor mandrel housing 587819701

Why it matters

Catching belt wear, electrical connection problems, and deck spindle (mandrel) wear early prevents bigger failures like damaged pulleys, overheated clutches, and repeated no-start situations.

Craftsman riding mowers and lawn tractors use engines from several major manufacturers, most commonly Briggs & Stratton, Kohler, and Kawasaki depending on the specific tractor and production run. For your Craftsman model 917203930, the exact engine brand and model are listed on the engine ID label and in the 917203930 owner's manual.

How to identify the engine brand on model 917203930

Use these quick checks on your tractor:

• Look for the engine shroud decal (top cover) showing the brand name
• Find the engine ID tag (often near the valve cover, blower housing, or starter)
• Record the engine model, type, and code (or spec number)
• Match that engine ID to the maintenance specs in the manual
• Use the engine ID when ordering tune-up parts (air filter, spark plug, fuel filter)

Common engine brands used on Craftsman lawn tractors

Craftsman has sourced engines from multiple suppliers over the years. Here is what we see most often on riding mowers and tractors:

Engine brand	Typical identifiers	What it affects most
Briggs & Stratton	Model-Type-Code format	Tune-up parts, carburetor kits, ignition parts
Kohler	Model and spec number	Oil filter, starter, charging system parts
Kawasaki	Model and spec number	Air filter, fuel system parts, ignition parts

Why it matters

The tractor model number (917203930) helps us match chassis and deck parts, but the engine brand and engine model control many maintenance items and engine repair parts. Using the engine ID prevents ordering the wrong filter, plug, or carburetor component.

Craftsman model 917203930 is typically identified by the product date on the tractor’s ID tag, not by the model number alone. For this model family, the date code format commonly reads as MMDDYY, which points to a 2011 build year when the tag shows a 2011 ending.

Where to find the build date on your tractor

We use the tractor’s ID tag (often near the seat, under the hood, or on the frame) to confirm the exact year.

• Locate the product identification tag or sticker
• Look for a date code or manufacture date line
• Read the code as month, day, year when it’s in a 6-digit format
• Write down the full code before ordering parts
• Cross-check the format in the 917203930 owner's manual

How to read the common Craftsman date code

Many Craftsman riding mowers and tractors use a 6-digit date code that reads like this:

Example date code	How we read it	Resulting date	Year
072811	07 / 28 / 11	July 28, 2011	2011

Why it matters

The year and build date help match the correct steering, deck, and electrical parts because Craftsman tractors can have mid-year changes (belt routing, PTO switch style, or wiring harness revisions).

If you are troubleshooting a no-start or click-no-crank issue while confirming the ID tag, follow the steps in riding lawn mower engine clicks but doesnt turn over video.
