What year was Craftsman 917270513 made?
The Craftsman lawn tractor model 917270513 is most commonly associated with the mid-2000s production era (about 2004 to 2006) for Craftsman LT-series tractors. For the most reliable confirmation, match your tractor’s product ID and decal information to the parts list in the 917270513 owner's manual.
How to confirm the build timeframe on your tractor
We recommend using identifiers that are physically on the machine, since tractors can be sold, serviced, or re-decaled over time.
- Check the model and serial tag (often under the seat, on the frame, or near the engine area)
- Look for decal sets and option labels (deck size, transmission type, engine family)
- Compare your tractor’s assemblies (seat, steering, chassis) to the illustrated parts breakdown
- Verify whether your mower deck is a 42-inch deck (common on this model family)
- Record the engine model and type code from the engine label (engine date codes can narrow the year)
Where the manual helps most
The manual for model 917.270513 includes detailed illustrated parts lists for major sections such as chassis, steering, and seat assemblies. That makes it a strong reference point for confirming you have the correct model family and configuration. Use the 917270513 owner's manual to cross-check key assemblies and part descriptions.
Quick reference: what “mid-2000s” means in practice
| What you’re checking | What it tells you | Why it helps |
|---|---|---|
| Model/serial tag | Exact identity of the tractor | Confirms you are working from the right parts list |
| Engine label | Engine build window | Engine date often aligns closely with tractor build |
| Deck configuration | Common platform era | Deck and belt routing changed across generations |
Why it matters
Knowing the correct production era helps you choose the right replacement parts (like belts, blades, steering parts, and seat hardware) and prevents ordering mismatches caused by similar-looking Craftsman LT tractors.

Who makes Craftsman push mower engines?
Craftsman push mower engines are commonly supplied by major small-engine manufacturers; for Craftsman equipment like model 917270513, the 917270513 owner's manual shows the tractor uses a Briggs & Stratton engine (manual lists Briggs model 287707-1255-E1), which is a strong indicator of the engine sourcing you will often see across Craftsman gas-powered mowers.
What we see on model 917270513 (and what it means)
The documentation for Craftsman lawn tractor 917270513 identifies the engine as Briggs & Stratton. That does not mean every Craftsman push mower uses Briggs, but it confirms Briggs is a primary supplier for Craftsman gas equipment.
- The manual lists the engine as Briggs (with a specific Briggs model number).
- Craftsman has also used other engine brands on certain mower lines and years.
- The most reliable way to confirm your push mower engine maker is the engine ID label on the engine itself.
How to identify who made your Craftsman push mower engine
Check the engine shroud or valve cover area for an ID tag or stamped label.
- Look for the engine brand name (Briggs & Stratton, Kohler, Kawasaki, etc.).
- Record the model, type, and code (Briggs format) or the equivalent ID fields.
- Match that ID when ordering tune-up parts (spark plug, air filter, fuel filter).
- Use your mower’s model number to cross-check in the parts list.
Quick comparison: where to confirm the engine manufacturer
| What you check | Best for | What you’ll learn |
|---|---|---|
| Engine ID label | Fastest, most accurate | Exact engine manufacturer and engine model |
| Mower/tractor owner’s manual | Specs and maintenance | Engine family and service info |
| Parts diagram/engine breakdown | Ordering parts | Exact replacement parts by engine model |
Why it matters
Engine manufacturer determines the correct maintenance parts and specs (spark plug type, oil type, filters). For example, the 917270513 manual lists key engine-related specs such as oil viscosity guidance and a specific spark plug type, which helps prevent hard starting and poor performance.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor model 917270513, a full engine replacement typically runs $600 to $2,500 total (engine, labor, and incidentals). Labor is usually 4 to 8 hours, and the final price depends on engine type, shop rates, and whether related drive or safety items need attention.
Typical cost breakdown
- Engine assembly: $300 to $1,800 (most of the cost)
- Labor: $300 to $900 (shop rate and hours)
- Extra parts and supplies: $25 to $200 (fuel line, clamps, oil, filter, spark plug)
- Pickup/delivery (if used): $0 to $150
| What you are paying for | Typical range | Notes |
|---|---|---|
| Engine + installation | $600 to $2,500 | Most common all-in range for riding mowers |
| Labor time | 4 to 8 hours | More time if bolts are seized or wiring is damaged |
| “While you’re in there” items | $25 to $200 | Often recommended during engine swaps |
What can push the price higher
- The replacement engine requires mounting or wiring changes.
- The tractor has starting or interlock issues that must be corrected before it is safe to run.
- The mower deck or drive system has wear that shows up once the engine is out (belts, pulleys, mandrels).
If your tractor has symptoms like clicking, no-crank, or cranks-but-won’t-start, we recommend troubleshooting first because those problems are often battery, starter, fuel, or safety-switch related, not a failed engine. Use the 917270513 owner’s manual for the operator-presence and interlock checks and basic maintenance guidance.
Quick “replace vs. repair” checklist
- Replace the engine when: low compression, thrown rod, cracked block, severe internal damage
- Repair first when: stale fuel, clogged fuel filter, dirty air filter, bad spark plug, loose wiring
- Confirm safety operation: the engine should shut off if you leave the seat under certain conditions (interlock system)
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Verifying fuel, ignition, cooling-fin cleanliness, and the operator-safety interlock system first helps avoid paying for an engine when a simpler fix restores reliable starting and mowing.

What engine does Craftsman riding mower use?
Craftsman lawn tractor model 917270513 uses a 14.5 HP engine and a 42-inch mower deck, as specified in the model’s documentation. To identify the exact engine manufacturer and engine model number, match the engine ID label on your tractor to the details in the 917270513 owner's manual.
How to identify the exact engine on your 917270513
Use the engine ID tag so you get the correct tune-up parts (spark plug, air filter, fuel filter) and service specs.
- Find the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (or serial)
- Use those numbers when shopping for engine parts and maintenance items
- If the label is missing, use the tractor model 917270513 plus engine layout (single-cylinder) to narrow matches
- Follow the manual’s maintenance schedule for oil changes and air filter service
Engine-related specs listed for this model
These are the key operating specs from the manual that tie directly to starting, lubrication, and tune-ups.
| Item | Specification |
|---|---|
| Engine power | 14.5 HP |
| Fuel capacity and type | 1.25 gallons, unleaded regular |
| Oil type | SAE 30 (above 32°F); SAE 5W-30 (below 32°F) |
| Oil capacity | 3.0 pints |
| Spark plug | Champion RC12YC; gap 0.030 in. |
Why it matters
The engine’s model and type determine the correct carburetor settings, ignition parts, and maintenance intervals. Using the specified oil viscosity and spark plug gap helps the engine start reliably and reduces wear.
If you are also servicing the cutting system, replace worn blades with a compatible option such as the husqvarna lawn tractor mulching blade, 21-in 532134149.
