How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding lawn tractor like model 917276050, a complete engine replacement (engine plus labor) typically runs $260 to $1,800, with about 6 hours of labor in many shops. Exact cost depends on the engine type, parts needed, and local labor rates; confirm specs in the 917276050 owner's manual.
What drives the total price
- Engine cost (new or remanufactured) is usually the biggest variable.
- Labor time is higher on riding tractors than walk-behind mowers because of wiring, throttle/choke linkages, and drive components.
- Extra parts often add cost (fuel line, clamps, battery cables, mounting hardware).
- Diagnosis time may be billed if the shop verifies the engine is truly failed.
- Pickup and delivery can add a separate fee.
Typical cost breakdown (what you are paying for)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $200 to $1,500 | Varies by horsepower and crankshaft configuration |
| Labor | $200 to $600 | Often 5 to 8 hours depending on shop rate |
| Misc. parts and fluids | $20 to $150 | Oil, filter, fuel line, hardware |
Before replacing the engine (quick checks)
We recommend ruling out common no-start or no-crank issues first because they can look like a “bad engine.”
- Battery charge and cable connections
- Starter solenoid and starter operation
- Safety interlock switches (seat, brake, PTO)
- Fuel quality and fuel delivery
- Compression and spark
If the engine clicks but does not turn over, use the steps in riding lawn mower engine clicks but doesnt turn over video to narrow it down before committing to an engine.
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. A quick diagnosis can prevent replacing an engine when the real issue is a battery, wiring, or a safety circuit problem.

What brand engine does Craftsman use?
Craftsman lawn tractors can use engines from several manufacturers; for the Craftsman 917276050 specifically, the owner’s manual identifies it as a 22.0 HP, low-emission internal combustion engine but does not call out the engine maker by brand. For the exact engine brand and model, we use the engine ID label and the specifications section in the 917276050 owner's manual.
How to identify the engine brand on your 917276050
Check the engine identification label on the engine itself; it lists the manufacturer and model family.
- Lift the hood and look for a sticker or metal tag on the blower housing or valve cover
- Write down the model, type, and code (or spec) numbers
- Match those numbers to the engine parts list when ordering tune-up parts (spark plug, air filter, oil filter)
- If the label is dirty, wipe it gently; avoid spraying water into the air intake
- Keep the numbers with your tractor model number 917276050 for future parts lookups
Common engine brands used on Craftsman lawn tractors
Across Craftsman riding mowers and garden tractors, the most common engine suppliers are:
- Briggs & Stratton
- Kohler
- Kawasaki
- Tecumseh (older models)
Quick comparison
| Engine brand | Typical use on Craftsman tractors | What to look for on the ID tag |
|---|---|---|
| Briggs & Stratton | Very common on many Craftsman models | “Briggs & Stratton” name plus model/type/code |
| Kohler | Common on some mid to higher HP models | “Kohler” plus model/spec numbers |
| Kawasaki | Less common, often premium applications | “Kawasaki” plus model/spec numbers |
Why it matters
The engine brand determines the correct maintenance parts and specs (spark plug type, oil filter, air filter, and tune-up intervals). Using the engine ID tag prevents ordering the wrong parts even when the tractor model is correct.

What model number is the Craftsman 42 riding mower?
For the Craftsman riding mower on this page, the model number is 917.276050 (often written without the dot as 917276050). Confirm the exact model and deck size on the ID label and in the 917276050 owner's manual.
How to confirm the correct model number on your mower
Use these quick checks so you order the right Craftsman parts (belts, blades, switches, and decals):
- Look for the product ID label under the seat, on the frame near the engine, or near the rear fender
- Match the model number format exactly (for this unit: 917.276050 or 917276050)
- Verify the mower deck size listed on the label and in the manual
- If your mower is a “42-inch” deck model, do not assume it matches this page without checking the label
- Use the manual’s parts diagrams to confirm assemblies before ordering
42-inch vs 50-inch: why the deck size matters
The manual excerpt for model 917.276050 identifies it as a garden tractor with a 50-inch mower deck, so a “Craftsman 42 riding mower” can be a different model even if it looks similar.
| What you’re checking | Model 917.276050 (this page) | Many “Craftsman 42” riders |
|---|---|---|
| Model number | 917.276050 / 917276050 | Different 917.xxxxxx number or other series |
| Deck size | 50-inch | 42-inch |
| Common mismatch risk | Belt and blade length | Spindle and deck parts |
If you are ordering parts, verify one key part by function
Once you confirm the model number, match the part to the system you’re repairing:
- Mower deck drive: belt routing and belt length must match the deck size
- Blade engagement: PTO switch and wiring must match the tractor’s interlock design
- Steering: tie rod and drag link lengths vary by chassis
For example, if your blades will not engage, the switch.pto 582107601 is a common electrical part to check on this model.
Why it matters
Using the wrong model number (especially mixing up 42-inch and 50-inch decks) leads to incorrect belts, blades, and deck hardware. Confirming 917.276050 first keeps repairs faster and avoids returns.

What year did Craftsman make the 917276050?
Craftsman model 917276050 was made during the LT1000-era production run, which is typically late 1990s through mid-2000s for many 917-series lawn tractors. For the most accurate build timeframe for your exact unit, we use the identification information and specifications listed in the 917276050 owner's manual.
How to pinpoint the year for your exact tractor
Craftsman 917-series tractors often share similar chassis and parts across multiple years, so the model number alone does not always narrow it to a single year.
Use these checks:
- Locate the model and serial label (commonly under the seat or on the frame near the seat pan).
- Record the serial number exactly as shown.
- Compare the tractor’s configuration to the manual’s parts listings (electrical, chassis, steering, decals).
- Match key assemblies on your tractor to the illustrated parts breakdowns.
- If your tractor has been rebuilt, prioritize the serial label over replaced components.
What the manual confirms for model 917276050
The documentation we have for this tractor is explicitly labeled TRACTOR MODEL NUMBER 917.276050 and includes detailed parts breakdowns for systems like:
- Electrical (ignition key, PTO switch, harness)
- Steering assembly (drag link, tie rod, ring clip)
- Wheels and tires (front axle cap, flange bearing)
That confirms you are working with the correct model family and parts system, even when the exact production year varies.
Common identifiers that help date a Craftsman 917-series tractor
| Identifier | Where you’ll see it | What it helps with |
|---|---|---|
| Model number (917276050) | ID label | Confirms the correct parts diagrams |
| Serial number | ID label | Narrows production batch/timeframe |
| Engine model/type code | Engine shroud/valve cover area | Helps date the engine (often close to tractor build) |
| Decal set and dash layout | Hood/dash/fenders | Helps match to a production period |
Why it matters
Knowing the correct year range helps us match the right wiring harness, PTO switch, belts, and steering parts so you avoid near-miss substitutions that look similar but fit differently.
