How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding tractor like model 917276911, a full engine replacement typically runs about $800 to $2,500 installed (engine plus labor). The total depends on the engine type, whether the replacement is a direct-fit, and how much teardown is required.
- Engine price: Most replacement riding mower engines fall roughly $500 to $1,800.
- Labor time: Commonly 4 to 8 hours for a riding tractor engine swap.
- Extra parts and supplies: Oil, filter, fuel line, clamps, belts, and hardware often add $25 to $200.
- Related repairs found during teardown: Worn pulleys, wiring, or PTO components can raise the bill.
- Shop rates: Local labor rates vary widely.
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $500 to $1,800 | Biggest variable; direct-fit costs less to install |
| Labor | $300 to $900 | Often 4 to 8 hours depending on access and rust |
| Fluids, filters, misc. | $25 to $200 | Oil change and small parts are common add-ons |
| Estimated total | $800 to $2,500 | Most jobs land in this band |
We see many tractors that need a battery, fuel, or safety switch fix instead of an engine.
- Verify the PTO is disengaged and the brake is set
- Check the operator presence (seat) switch and wiring
- Inspect for stale fuel, a dirty air filter, or a faulty spark plug
- Confirm the engine is not losing power from low oil or a clogged muffler
- Use the troubleshooting chart in the 917276911 owner’s manual
An engine replacement is one of the highest-cost repairs on a riding mower. Spending a few minutes on basic troubleshooting and safety interlock checks can prevent paying for an engine when the real issue is fuel delivery, ignition, or a switch.

How to find Craftsman parts?
For Craftsman model 917276911, the fastest way to find the right replacement part is to use the parts diagram and the parts list from the model-specific manual, then match the diagram callout to the exact part name and number before ordering.
- Confirm the full model number on the tractor ID tag: 917276911
- Open the 917276911 owner's manual and locate the parts list or exploded-view references
- Identify the system you are repairing (mower deck, steering, drive, electrical)
- Use the diagram callout number to match the exact part description
- Match your old part to the listing (mounting holes, pulley/bearing size, connector style)
- Order by the exact part number when possible (not just by description)
If you already know the area you are working on, these are examples of model-matched parts that are commonly replaced:
| Repair area | Example part to look up | What it affects |
|---|---|---|
| Mower deck spindle/mandrel | Lawn tractor mandrel housing 587819701 | Blade spin quality, vibration, noise |
| PTO engagement | Switch.pto 582107601 | Blades turning on and off |
| Starting/keys | Molded ignition key 532140403 | Ability to start and operate |
- Compare the old part to the diagram and the part listing, not just the tractor’s appearance
- Replace worn fasteners when needed (nuts, lock nuts, washers) so parts stay tight
- For deck and drive issues, inspect belts, idlers, and pulleys together; one worn part can damage the next
Craftsman tractors often have multiple configurations within the same series. Using the 917276911 manual and diagram callouts helps ensure the part you buy fits your exact mower deck, transaxle setup, and controls.

Is it worth repairing a lawn mower engine?
Yes; repairing the engine on your Craftsman 917276911 front-engine lawn tractor is worth it when the issue is routine maintenance or a common no-start problem and the tractor is otherwise in good shape. It is not worth it when the engine has major internal damage or repair cost nears replacement value.
- Repair it if it cranks normally and the problem points to fuel, spark, air filter, or basic tune-up.
- Repair it if the tractor has low hours and the deck, steering, and transaxle operate smoothly.
- Repair it if the fix is cleaning the fuel system after storage (stale fuel is common).
- Replace the engine or tractor if it knocks, seized from low oil, or has a bent crankshaft.
- Replace the engine or tractor if the crankcase is cracked or it threw a rod.
| Symptom | Typical path | Common cause |
|---|---|---|
| No-start after storage | Repair | Stale fuel, dirty carb, fouled plug |
| Clicks but won’t crank | Repair | Battery, cables, solenoid, safety interlocks |
| Runs but lacks power | Repair first | Plug, air filter, fuel restriction |
| Loud knock or seized | Replace | Internal damage, oil-related failure |
Your manual calls out that fuel should generally be used within 30 days; stale or contaminated fuel often leads to fuel-system cleaning and no-start complaints. It also stresses routine checks like engine oil level and keeping debris off hot engine parts. See the 917276911 owner’s manual.
If the mower deck will not rotate, the troubleshooting chart points to obstructions, a worn belt, a frozen idler pulley, or a frozen blade mandrel. Deck drag can overload the engine and make it bog down. If your deck uses that exact assembly, a common fix is the lawn tractor mandrel housing 587819701.
Repairing the root cause (maintenance, stale fuel, or deck-drive drag) prevents spending engine-level money on a problem that is often inexpensive to correct.

What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917276911, the operator’s manual identifies it as a low-emission engine tractor rated at 26.0 HP with a 54-inch mower deck. For the exact engine manufacturer and model (for example, Briggs & Stratton or Kohler), use the engine identification label and confirm it in the 917276911 owner's manual.
Use these quick checks to match the engine brand and model correctly:
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code (or spec number)
- Match those numbers to the engine parts list and tune-up specs in the manual
- If the label is missing, check for a stamped ID on the engine shroud or block
- Confirm you are reading the tractor model tag as 917276911 (not the engine model)
The tractor model number tells us the chassis and deck configuration, but the engine ID determines the correct oil type, spark plug, air filter, fuel filter, and carburetor parts. Using the wrong engine spec is a common reason tune-ups and no-start fixes do not hold.
| Symptom | Most common cause | First check |
|---|---|---|
| Clicks but will not crank | Weak battery or bad connections | Battery charge and cable tightness |
| Cranks but will not start | Fuel or ignition issue | Fresh fuel, spark plug condition |
| Starts then stalls | Fuel delivery or safety circuit | Fuel flow, seat/brake switches |
| Runs rough under load | Dirty air filter or old fuel | Air filter, fuel quality |
If you are troubleshooting a no-crank or no-start condition, follow the steps in riding lawn mower engine clicks but doesnt turn over video or riding lawn mower engine spins but wont start video to narrow it down quickly.
These parts are commonly handled during maintenance and deck work on this tractor:
- Molded ignition key 532140403 (if the key is worn or damaged)
- Switch.pto 582107601 (if the blades will not engage)
- Lawn tractor mandrel housing 587819701 (if a spindle/mandrel is noisy or loose)

What year did Craftsman make the 917276911?
Craftsman model 917276911 is a specific garden tractor configuration (26.0 HP, 54-inch mower, electric start, 6-speed transaxle), but the operator’s manual for this model does not list a single “model year.” The most accurate way to pin down the year is to match the tractor’s product ID/serial information to the date-of-manufacture details shown in the 917276911 owner’s manual.
Use these checks on the tractor itself; they are the fastest way to confirm the build timeframe.
- Look under the seat or near the seat pan for the model/serial label.
- Check the frame rail (left or right side) for a sticker or stamped tag.
- Record the serial number exactly as shown (letters and numbers).
- Compare the label information to the identification guidance in the 917276911 owner’s manual.
- If the engine has its own tag (Briggs and Stratton or Kohler), record the engine model and code; engine codes often include a date.
The manual confirms the configuration for model 917.276911 (same model number format) but does not publish a calendar year.
| Item | What you’ll see | Why it helps |
|---|---|---|
| Tractor model | 917276911 | Confirms you have the correct parts list and manual |
| Mower deck size | 54-inch | Narrows deck-related parts and adjustments |
| Drive type | 6-speed transaxle | Helps match drive belt, pulleys, and linkage setups |
The exact year affects parts compatibility for wear items and running changes, especially in the mower deck and drive system (belts, idlers, mandrels, and PTO components). Confirming the ID label first prevents ordering the wrong revision.
If you are chasing a drive or deck issue while you identify the year, start by inspecting high-wear components such as idler pulleys and the PTO switch. For example, a worn idler can cause belt slip and poor cutting or drive performance; a failing PTO switch can prevent the clutch from engaging. Use the parts diagrams and procedures in the manual, then match by model/serial.
