How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor model 917272082, replacing the engine typically costs $600 to $2,500 total (engine plus labor), with labor commonly running 4 to 8 hours depending on how much has to be transferred (pulleys, wiring, exhaust, and controls). Check the 917272082 owner's manual for model-specific service and safety guidance before planning the job.
What drives the total cost
- Engine price: Most replacement riding mower engines fall roughly in the $400 to $1,800 range, depending on horsepower, brand, and whether it is a direct-fit engine.
- Labor time: A straightforward swap is faster; rusted fasteners, seized pulleys, or wiring repairs add time.
- Extra parts: Belts, pulleys, wiring, and hardware often get replaced during an engine job.
- Shop fees: Pickup/delivery, diagnostics, and disposal can add to the invoice.
- DIY vs. shop: DIY saves labor but still requires safe lifting, correct wiring, and proper belt routing.
Typical cost breakdown (what most customers see)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $400 to $1,800 | Biggest variable; direct-fit costs more but installs easier |
| Labor | $200 to $900 | Often 4 to 8 hours depending on complexity |
| Misc. parts and supplies | $25 to $250 | Belts, fuel line, clamps, oil, filter, hardware |
| Total installed | $600 to $2,500 | Wide range based on engine choice and condition |
When an “engine replacement” is not the best first step
Before committing to an engine, we recommend ruling out common no-start or no-crank causes:
- Weak battery or bad cables
- Safety interlock switch issue (seat, brake, PTO)
- Fuel problems (old gas, water in fuel, clogged filter)
- Ignition problems (loose spark plug wire, bad plug)
- Airflow and exhaust restrictions (dirty screen/fins, clogged muffler)
If the tractor clicks or cranks but will not start, use riding lawn mower engine spins but wont start video to walk through the most common checks.
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Confirming the real failure first helps you avoid paying for an engine when the issue is fuel delivery, wiring, or a safety circuit problem.

What year is my Craftsman mower serial number lookup?
On Craftsman lawn tractor model 917272082, the model number does not contain the build year; the year comes from the product serial number on the tractor’s ID label. Once you find that serial number, you can decode it to determine the manufacturing date.
Where to find the serial number
Check the tractor’s product identification label (not the engine label). Common locations include:
- Under the seat pan or on the seat deck
- On the rear fender or rear frame area
- Near the footrest area on the frame rail
- Under the hood near the dash tower
- On the chassis close to the transaxle
For label location diagrams and model identification details, use the 917272082 owner's manual.
How Craftsman serial numbers are commonly decoded
Many Craftsman riding mower serial numbers use a date-coded format where the first digits represent the month and day, and later digits represent the year.
Here is the most common pattern customers run into:
| Serial number digits | Meaning | Example value | Example meaning |
|---|---|---|---|
| 1st and 2nd | Month | 07 | July |
| 3rd and 4th | Day | 28 | 28th |
| 5th and 6th | Year | 11 | 2011 |
If your serial number begins with 072811, that decodes to July 28, 2011.
Quick checks to avoid a wrong year
Before you commit to a parts order or tune-up plan, we recommend these checks:
- Confirm you are reading the tractor serial number, not an engine serial number
- Write the serial number exactly as shown (include leading zeros)
- Compare the tractor’s deck and drive layout to the diagrams in the manual
- If your tractor has a 42-inch deck, verify deck parts match your configuration
- Use the model number 917272082 when searching parts to avoid near-match models
Why it matters
The correct manufacturing year helps you match the right mower deck, belt routing, and hardware revisions. Even within the same Craftsman model family, small changes can affect fit for items like a blade, mandrel, or ground drive belt.

What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917272082, the owner's manual identifies it as a 7.0 HP electric-start tractor with a low-emission engine. For the exact engine make and model (such as Briggs & Stratton or Kohler), we use the engine identification label and the specifications section in the 917272082 owner's manual.
How to identify the exact engine on model 917272082
We match the correct engine by using the engine’s model-type-code information (or engine family label) on the engine itself, then cross-checking it against the manual and parts diagrams.
- Look for an engine ID label on the blower housing, valve cover, or near the starter
- Write down the model, type, and code (or similar ID fields)
- Compare that information to the engine section in the manual and repair parts listings
- If the label is missing, use the tractor model number 917272082 plus the engine’s visible features (air filter style, muffler shape, carburetor layout)
- Use the manual’s product specifications and maintenance sections to confirm tune-up parts (spark plug, air filter, oil)
Common engine brands used on Craftsman lawn tractors
Craftsman riding mowers commonly use engines from a few major manufacturers. The exact brand depends on the production run and configuration.
| Engine brand | Typical identifiers | Where to check |
|---|---|---|
| Briggs & Stratton | Model-type-code format on label | Blower housing or valve cover |
| Kohler | Command/Courage-style model tag | Valve cover area or shroud |
| Tecumseh (older units) | Older-style model/spec tag | Shroud or recoil/starter area |
Why it matters
The engine brand and exact engine model determine the correct maintenance parts and settings, including spark plug type, air filter style, oil capacity, and carburetor or ignition components. That prevents hard starting, poor mowing power, and premature wear.
If you are troubleshooting a no-start or click-no-crank condition, the riding lawn mower engine clicks but doesnt turn over video helps narrow down whether the issue is battery, starter, solenoid, or safety interlock related.
