What year is Craftsman Model 9172559105?
Craftsman model 9172559105 does not have a single built-in “model year” like a car; the year is identified from the tractor’s product/serial number date code on the ID tag. Use the date code on your tractor to determine the exact year it was built.
Where to find the date code
On most Craftsman front-engine lawn tractors, the ID tag is typically located in one of these spots:
- Under the seat (seat pan area)
- On the rear fender pan near the seat
- On the frame rail near the engine
- Near the transaxle area on the frame
How to decode the build date
Many Craftsman tractors use a 6-digit date code format on the product/serial label:
- First 2 digits = month
- Next 2 digits = day
- Last 2 digits = year
Example
If your date code is 072811, that decodes to July 28, 2011.
| Date code | Month | Day | Year | Build date |
|---|---|---|---|---|
| 072811 | 07 | 28 | 11 | July 28, 2011 |
| 031905 | 03 | 19 | 05 | March 19, 2005 |
Why it matters
Knowing the build year helps us match the correct parts and diagrams for your Craftsman 9172559105, especially for wear items like belts, switches, and fuel system parts.
Parts that are commonly matched by exact build configuration
- Ground drive belt routing and length
- Blade drive belt routing and deck configuration
- Electrical interlock components (seat switch, PTO switch, ignition switch)
- Fuel tank and fuel cap style

What kind of engine does a Craftsman riding lawn mower have?
For the Craftsman riding lawn mower model 9172559105, the exact engine make and horsepower depend on the specific engine installed on your tractor; this model was commonly equipped with a single-cylinder gasoline engine. To identify yours, we recommend checking the engine ID tag on the blower housing or valve cover.
How to identify the engine on model 9172559105
Use these quick checks to get the engine brand and spec number without guessing:
- Look for an engine label on the top or side of the engine shroud (often lists model, type, and code).
- Check the valve cover area for a stamped model/spec number.
- Record the engine model and spec/type; those two fields are what parts lookups use.
- If the tractor cranks but will not start, confirm the safety circuits are allowing spark.
- If you only hear a click, focus on battery cables, solenoid, and starter circuit.

Common engine types you will see on Craftsman tractors like this
Most Craftsman front-engine lawn tractors in this class use one of these engine families:
| Engine family | Fuel | Typical configuration | What it means for you |
|---|---|---|---|
| Briggs & Stratton single-cylinder | Gasoline | 1-cylinder, vertical shaft | Very common; parts are matched by engine model/type/code |
| Kohler single-cylinder | Gasoline | 1-cylinder, vertical shaft | Also common; parts matched by spec number |
| Tecumseh (older units) | Gasoline | 1-cylinder, vertical shaft | Less common today; ID tag is essential |
Why it matters
The tractor model number (9172559105) identifies the chassis and mower deck parts, but engine service parts (carburetor parts, ignition parts, starter parts) are selected by the engine’s own model/spec. Getting that ID first prevents ordering the wrong tune-up or ignition components.

What size deck is a Craftsman 9172559105?
The Craftsman riding lawn tractor model 9172559105 uses a 42-inch mower deck (42 in. cutting width). That 42-inch deck size is the key spec to match when you’re buying blades, belts, or setting up the deck for an even cut.
How to confirm you have the 42-inch deck
Use these quick checks on your tractor before ordering parts:
- Measure the cutting path (blade tip to blade tip across the deck) with the blades straight
- Check the deck shell for a stamped size (often “42”) near the discharge chute
- Count blades: most 42-inch decks use two blades
- Compare your belt routing and pulley layout to the parts diagrams for model 9172559105
Parts that commonly match the deck size
Deck size matters most for belts and pulleys. For this model, these parts are commonly involved in deck drive issues:
- Lawn tractor blade drive belt 532110884 (deck belt)
- Lawn mower blade drive belt 582778701 (belt used on some deck configurations)
- V-idler pulley 532139123 (belt tension and tracking)
- Idler pulley 532101344 (belt routing support)
Quick comparison: deck-related belt symptoms
| Symptom | Most likely area | What to check first |
|---|---|---|
| Blades will not engage | PTO and deck belt drive | PTO switch operation, belt condition and routing |
| Belt keeps coming off | Idlers, guides, alignment | Idler pulley wobble, bent belt keepers |
| Cut is uneven | Deck setup | Tire pressure, deck level, blade condition |
Why it matters
A 42-inch deck determines the correct blade length, belt length, and pulley routing. Matching the deck size prevents wrong-part returns and helps your Craftsman tractor cut evenly and engage the blades smoothly.
