How to look up Craftsman model number?
For a Craftsman riding mower like model 917270723, we look up the model number on the tractor’s identification label, then use that exact number to find the correct parts list and the correct documentation in the owner's manual.
Where to find the model number on a Craftsman riding mower
On most Craftsman lawn tractors, the model and serial label is on the frame under the seat or on the underside of the seat.
- Park on a level surface, set the parking brake, and remove the key
- Lift the seat and look for a sticker or metal tag on the frame rails
- Check the underside of the seat if you do not see a tag on the frame
- Write the model number exactly as shown (for example, 917.270723 may appear with a dot)
- Record the serial number too; it helps match production variations
How we use the model number to get the right parts
Once you have the model number, match it exactly when searching. For this tractor, the model is 917270723.
| What you have | What it’s used for | Tip |
|---|---|---|
| Model number | Finding the correct parts diagrams and part numbers | Use all digits; do not shorten |
| Serial number | Confirming the correct version of the tractor | Keep it with your maintenance records |
| Engine model (if listed) | Engine-specific tune-up parts | Use it only for engine parts |
Why it matters
Craftsman tractors often share similar frames and decks across multiple models. Using the exact model number prevents ordering the wrong belt length, blade style, or deck hardware.
Common parts that depend on the correct model match
These are examples of parts where the model number matters for fit and routing:
- Ground drive belt (length and routing)
- Blade drive belt (deck size and pulley layout)
- Mulching blade and mandrel components
- Steering parts (sector gear, drag link)

What engine does Craftsman riding mower use?
The Craftsman riding mower model 917270723 uses a 17.0 HP gas engine with electric start (as listed in the tractor’s documentation). For the exact engine make and service details, use the specifications and maintenance sections in the 917270723 owner's manual.
What we can confirm for model 917270723
From the model-specific documentation, this tractor is identified as a 17.0 HP electric start 42-inch mower automatic lawn tractor.
Key identifiers you can rely on:
- Model number: 917270723
- Engine rating: 17.0 HP
- Starting system: electric start
- Mower deck size: 42 inches
- Drive type: automatic (per the manual cover)
How to identify the exact engine brand and model on your tractor
Many Craftsman tractors were built with engines from common suppliers; the fastest way to confirm your exact engine is to match the engine ID on the machine.
Check these locations:
- Engine blower housing (often near the recoil area, even on electric-start engines)
- Valve cover area
- Engine shroud label or stamped tag
- Frame tag under the seat or near the rear fender (sometimes lists engine family)
Specs that help when buying tune-up parts
Even when you are still confirming the engine brand, the manual provides service specs that are useful for maintenance planning.
| Item | Spec (from manual) |
|---|---|
| Spark plug | Champion RC12YC |
| Spark plug gap | 0.030 in |
| Gasoline capacity/type | 1.25 gallons, unleaded regular |
| Tire pressure | Front 14 PSI; rear 10 PSI |
Why it matters
The engine brand and model number determine the correct air filter, fuel filter, starter parts, and carburetor components. The tractor model number (917270723) is perfect for deck, belt, steering, and chassis parts, but engine ID is the key for many engine-specific maintenance items.

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman lawn tractor model 917270723 is worth it when the mower deck, transmission, and steering are still solid and the total repair cost stays well below the price of a comparable replacement tractor. If the deck is rusted through or multiple major systems are failing, putting money into an engine swap usually does not pay off.
Quick decision checklist
- The deck shell is structurally sound (no cracks, no rust-through)
- The transmission drives smoothly (no slipping, no loss of drive)
- Steering and front axle are tight enough to mow safely
- You can source the correct engine and mounting hardware for 917270723
- The total cost (engine + tune-up parts + labor) is clearly less than replacing the tractor
What to inspect before you spend money
Use this as a fast condition check before committing to an engine replacement:
| Area to check | What “good” looks like | What pushes you toward replacement |
|---|---|---|
| Mower deck | Solid shell, normal wear | Rust holes, cracks, severe vibration damage |
| Blade/mandrel area | Spins smoothly, no wobble | Bent mandrel, loud bearing noise, wobble |
| Drive system | Consistent forward/reverse | Belt slip, loss of drive, repeated failures |
| Electrical starting | Clean connections, reliable crank | Chronic no-crank issues beyond battery/cables |
Related repairs that often come up with engine problems
If the tractor clicks but will not start, the manual points to wiring, battery connections, the ignition switch, and the starter solenoid as common causes. Review the troubleshooting steps in the owner's manual.
Common parts that may be involved in “no start” or “no crank” situations include:
- Solenoid 532146154 (starter solenoid)
- Battery cables and terminals (clean and tighten)
- Fuse and wiring connections (inspect for looseness or damage)
Why it matters
An engine swap only makes financial sense when it restores a tractor that is otherwise dependable. If the deck and drivetrain are healthy, you get more seasons out of the machine; if they are worn out, the new engine will not fix poor cut quality, vibration, or drive problems.

Where can I find my lawn mower engine model number?
On your Craftsman lawn tractor model 917270723, the engine model number is on the engine itself (not on the mower deck or frame). For this tractor, the engine is a Briggs & Stratton model 311707, type 0132-E1; you can confirm the tractor and engine identification details in the owner's manual.
Where to look on the engine
We recommend checking these common ID locations on Briggs & Stratton V-twin style engines:
- On the blower housing (the metal shroud over the flywheel) near the starter
- On the valve cover area (top/side of the engine)
- On a stamped metal pad on the engine block near the cylinder head
- On an ID label or tag near the spark plug wire routing
Clean the area first; grass dust and oil film can hide the stamping or label.
What numbers you need (and how to write them down)
For parts lookup and service, capture all three fields exactly as shown:
- Model (example for this tractor: 311707)
- Type (example: 0132-E1)
- Code (a longer number that indicates the build date)
Quick reference
| Item | Where it’s found | Why it matters |
|---|---|---|
| Tractor model number | Tractor ID label and manual | Ensures you get the right chassis and deck parts |
| Engine model/type/code | Stamped/label on engine | Ensures tune-up and engine parts match |
Why it matters
The same Craftsman tractor series can use different engines or engine variants. Using the exact engine model/type/code prevents ordering the wrong ignition, carburetor, or maintenance parts.

How do I tell what year my Craftsman riding mower is?
To tell the year of your Craftsman riding mower, we match the model and serial information on the tractor to the manufacturing date code used for that unit. For Craftsman model 917270723, the most reliable method is to use the identification numbers and confirm them against the details in the 917270723 owner's manual.
Where to find the numbers you need
On most Craftsman front-engine lawn tractors, the model and serial label is on the frame under the seat area or near the rear fender.
- Look for a sticker or metal tag that lists MODEL and SERIAL.
- Write the serial number exactly as shown (letters and numbers).
- If the label is dirty, wipe it clean so every digit is readable.
- If the label is missing, check for a stamped number on the frame rail.
How the date code is commonly formatted
Many Craftsman riding mower serial/date codes use a month-day-year pattern (often shown as MMDDYY within the serial string). When that format is used:
- First 2 digits = month
- Next 2 digits = day
- Last 2 digits = year
Example
If you see 072811 in the date portion of the serial number, that indicates July 28, 2011.
Quick check table
Use this to translate the date portion if your serial includes an MMDDYY block.
| Date code block | Reads as | Example result |
|---|---|---|
| MM | Month | 07 = July |
| DD | Day | 28 = 28th |
| YY | Year | 11 = 2011 |
Why it matters
Knowing the build year helps us match the correct repair parts and specs for your tractor, especially for wear items like belts, blades, and deck components. For example, if you are servicing the mower deck, you can cross-check fit with parts such as the husqvarna lawn tractor ground drive belt, 1/2 x 82-in 532140294 and the husqvarna lawn tractor mulching blade, 21-in 532134149.
