How to find riding lawn mower model number?
On the Craftsman 107289920 rear-engine riding mower, the model number is typically printed on a product ID label on the frame or under the seat area. For the most reliable location and label examples, use the 107289920 operator's manual.
Common places to check on a rear-engine rider
Look for a sticker or metal tag; wipe off grass and oil so you can read it.
- Underside of the seat pan or on the seat deck (lift the seat/deck to access the engine compartment area)
- Rear frame area between the rear wheels
- Left or right side of the frame near the engine
- Near the starter/engine shroud area
- On or near the cutting deck shell (outer edge, not underneath the spinning blade area)
What the label usually shows (and what to write down)
Record the full model number exactly as printed; it is what we use to match parts like blades, switches, and wiring.
| Label item | What it’s used for | Example for this mower |
|---|---|---|
| Model number | Finds the correct parts diagrams | 107289920 |
| Engine model/type/code | Engine-specific tune-up parts | Briggs & Stratton info on engine label |
| Serial number | Identifies production run | Varies by unit |
Tips to avoid ordering the wrong parts
- Copy the model number character-for-character (including dots or dashes if shown).
- If the label is faded, take a photo in bright light after cleaning the area.
- Use the model number to confirm deck-related parts before replacing items like a blade 1737252BZYP.
Why it matters
Craftsman riding mowers can look similar across years, but parts like the mower blade, seat switch, and wiring harness can differ by model and deck configuration. Using the exact model number keeps fit and function correct.

How to identify a lawn mower engine?
On your Craftsman 107289920 rear-engine riding mower, we identify the engine by locating the engine identification label or stamped numbers on the engine itself (not on the mower deck). The model-type-code is typically on the blower housing, near the muffler, or near the air cleaner; match those numbers when ordering parts.
Where to look on the engine
Check these common locations first (clean the area so the numbers are readable):
- On the sheet metal shroud directly above or near the muffler
- On the front or side of the engine shroud near the air cleaner housing
- Near the starter or valve cover area on the engine
- On a sticker plate on the blower housing (often easiest to read)
- On the engine itself, not on the mower frame or cutting deck
How to record the engine ID correctly
Write the ID exactly as shown; many mower engines use a 3-part format.
| What you may see | What it means | Why we need it |
|---|---|---|
| Model | Engine family/size | Identifies the correct parts list |
| Type | Specific configuration | Matches carburetor, muffler, linkage, etc. |
| Code/Date | Build date/variant | Helps avoid wrong revisions |
Quick safety steps before you inspect
We follow the same safety approach used throughout the mower’s operating instructions.
- Turn the ignition switch to OFF and remove the key
- Let the engine and muffler cool completely
- Keep the area free of grass and debris buildup
- Never adjust or inspect parts with the engine running
- Wipe up any fuel or oil spills before continuing
Why it matters
The Craftsman model number (107289920) identifies the mower, but the engine model-type-code identifies the exact engine configuration. Using the engine ID prevents ordering the wrong ignition parts, fuel system parts, or exhaust components.
For control locations and safe shutdown steps while working around the engine, use the 107289920 owner’s manual.

What is the advantage of a rear engine mower?
A rear-engine riding mower like the Craftsman 107289920 puts the engine weight over the drive wheels, which improves traction on grass and helps the mower feel stable while turning and mowing. The rear-engine layout also keeps the front end more open for steering and deck visibility.
Key advantages you will notice
- Better traction: more weight on the rear tires helps reduce wheel slip on typical lawns.
- Stable feel: the mower tends to track steadily when you are mowing at a consistent ground speed.
- Good deck awareness: with the engine behind you, it is often easier to judge where the deck is cutting.
- Simple mowing controls: on this model, you can set cutting height with a switch and engage blades with the yellow blade switch.
- Convenient service access: common maintenance points (battery, wiring, seat switch area) are typically easy to reach under the seat and rear bodywork.
How this matters on model 107289920
Our manual shows the mower deck cutting height range is approximately 1-1/2 in. to 3-3/4 in., adjusted using the cutting height switch. Running the throttle at FAST while mowing and engaging the blades helps the deck cut cleanly and reduces stalling in thicker grass. See the 107289920 owner’s manual for the control locations and operating steps.
Quick operating checklist (best results)
- Set the throttle/choke to FAST before mowing.
- Choose a higher cutting height for the first pass in tall grass.
- Engage blades only at higher engine speed.
- Slow ground speed if the cut looks rough.
- Keep the underside of the deck clean to prevent clumping.
Common tradeoffs (so you can plan)
| What you gain | What to watch for |
|---|---|
| Strong rear-wheel traction | Still avoid steep slopes and wet grass where any rider can slip |
| Stable mowing feel | Turning tightly at high speed can scuff turf |
| Easy height changes via switch | Keep linkage clean and lubricated for smooth adjustment |
Why it matters
Choosing the right mower layout affects cut quality, traction, and how confidently you can mow around landscaping. With a rear-engine rider, you typically get a stable, traction-friendly platform that performs best when you keep blades sharp and engine speed up.

What year did Craftsman make the Model 107289920?
Craftsman model 107289920 was in production by April 2009; the operator’s manual for this zero-turn rear-engine rider shows a revision date of 04/2009, which confirms the mower was being supported at that time. For the exact build year of your specific unit, match the model and serial tag information to the date guidance in the 107289920 operator’s manual.
What we can confirm from the documentation
The manual cover identifies the mower as a ZTS zero-turn rear engine rider with electric start (26 HP Briggs & Stratton engine with a 52-inch mower), and it lists:
- Model No. 107.289920
- Manual revision: Revision F
- Revision date: 04/2009
That revision date is the most reliable “year marker” available in the model documentation.
How to pinpoint the exact year for your mower
Use these checks to narrow it down to the specific year your mower was built:
- Locate the model and serial number label (commonly under the seat area or on the frame near the seat support).
- Confirm the model number reads 107289920 exactly.
- Record the full serial number; the serial format is what typically ties to a production date.
- Compare your mower’s configuration (52-inch deck, electric start, safety interlocks) to the specifications section in the 107289920 operator’s manual.
- If you are replacing safety or electrical items, verify the part callouts against the manual’s parts lists.
Quick reference: “manual date” vs “mower build date”
| Item | What it tells you | What it does not tell you |
|---|---|---|
| Manual revision date (04/2009) | The model was supported and documented by that date | The exact build year of your specific serial number |
| Serial number on the mower | The best way to identify the unit’s production timeframe | Nothing unless you match it to the maker’s dating scheme |
Why it matters
Knowing the correct production year helps you avoid mismatched parts and wiring differences, especially on safety interlocks and starting circuits. For example, the seat safety circuit commonly uses a specific seat switch; confirming the correct listing helps when ordering a replacement like the briggs and stratton switch, seat 7023354YP.
