How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor like model 917271650, a full engine replacement typically runs about $260 to $1,800 installed, depending on the engine, labor rates, and whether related items (belts, pulleys, wiring) also need service.
What drives the total price?
- Engine cost (new, remanufactured, or used)
- Labor time (engine swaps on riding tractors commonly take most of a day)
- Extra parts discovered during teardown (worn belts, damaged pulleys, loose hardware)
- Shop supplies (oil, filter, fuel line clamps, sealants)
- Pickup and delivery (if you do not transport the tractor)
Typical cost breakdown
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part) | $200 to $1,400 | Varies by horsepower, crankshaft size, and brand compatibility |
| Labor | $200 to $600 | Often 4 to 8 hours depending on rust, access, and wiring |
| Fluids and tune-up items | $20 to $120 | Oil, filter, spark plug, fuel filter |
| “While you’re in there” parts | $0 to $300 | Belts, pulleys, hardware as needed |
Before you replace the engine, confirm it is actually bad
We recommend checking these common “no start” causes first because they can look like a failed engine:
- Weak battery or poor cable connections
- Safety interlock issue (seat switch, brake/clutch switch, PTO/attachment clutch switch)
- Bad starter solenoid or starter motor
- Old fuel or water in fuel
- Spark plug wire loose, dirty air screen/fins, or clogged muffler
A quick reference for the correct starting and interlock behavior is in the 917271650 owner’s manual.
Why it matters
An engine is one of the highest-cost repairs on a riding mower. Verifying basics like the operator-presence interlock system and fuel/ignition condition helps you avoid paying for an engine when the real fix is a switch, wiring repair, or tune-up.

How to look up Craftsman model number?
For a Craftsman riding mower like model 917271650, we look up the model number by finding the model and serial tag on the tractor, then matching that exact number when ordering parts or checking specs in the 917271650 owner's manual. On most units, the tag is on the frame under the seat.
Where to find the model and serial tag
Check these common locations first:
- On the frame directly under the seat (lift the seat up)
- On the underside of the seat pan
- Near the rear fender or hitch plate area on the frame
- On a sticker or metal plate close to the engine compartment (less common)
How to read the number correctly
Craftsman tags often show the model with punctuation (for example, 917.271650). When searching parts, we use the digits without the dot:
| What you see on the tag | What to enter for parts lookup |
|---|---|
| 917.271650 | 917271650 |
Tips to avoid ordering the wrong parts
These quick checks help ensure the parts diagram matches your tractor:
- Write down the full model number and serial number before shopping
- Match the deck size listed for your tractor (this model is a 42-inch mower deck)
- Confirm the part fits your section (mower deck, wheels and tires, steering, drive)
- Use the manual parts lists and diagrams to verify the exact item name
Why it matters
Craftsman tractors can look similar across years, but small changes in the mower deck, transaxle, belts, and steering parts can make a part incompatible. Using the exact model number (917271650) keeps your repair accurate and saves time.

What year did Craftsman make the 917271650?
Craftsman model 917271650 is a specific lawn tractor model number, but the year of manufacture is not defined by the model number alone. We use the tractor’s product identification information (typically the serial number and/or date code on the ID label) to match it to the correct production year; see the 917271650 owner's manual for label location guidance.
How to find the build year on a Craftsman 917271650
On most Craftsman front-engine lawn tractors, the most reliable way to identify the year is to read the product ID label and use the serial number/date code.
- Look under the seat area and around the rear fender pan for an ID label
- Check the frame rails near the engine or the footrest area
- Write down the full model number (917271650) and the full serial number
- If the label includes a date code, record it exactly as shown
- Use the recorded information when ordering parts like a drive belt, blade, or ignition key
What we can confirm from the documentation
The documentation confirms the tractor is identified as TRACTOR MODEL NUMBER 917.271650 and provides model-specific parts breakdowns (chassis, steering, seat, mower deck). That confirms you have the correct model family for parts lookup, but the manual pages shown do not list a single “manufactured in” year.
Model-specific parts shown in the manual (examples)
| System | Example part listed for 917271650 | What it helps identify |
|---|---|---|
| Mower deck | Blade, mulching (listed as 134149) | Confirms deck configuration and compatible blade style |

- Engine shroud or valve cover area: engine model/type and code on a sticker or metal tag
- Frame under the seat: model and serial label on many riding mowers
- Rear fender pan or near the transaxle: additional ID decals on some builds
- Inside the hood area: label near the dash tower on some tractors
Battery and charger date code locations (common)
If your question is specifically about Craftsman batteries and chargers, these are the most common spots:
- Battery: on the top or side of the plastic case, near the cells; often a 6-digit code
- Charger: on the bottom label; sometimes also near the cord entry
- Packaging/receipt: purchase date is often the most useful “date reference” for service
Quick ID checklist (what to write down)
Use this list so we can match the right parts and service info:
- Tractor model number: 917271650
