How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding tractor like model 917288610, a complete 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 cost
- Engine type and horsepower (OEM-style replacement vs. compatible engine)
- Labor time (riding mower engine swaps commonly take most of a day)
- Extra parts discovered during removal (worn belts, pulleys, mounts)
- Electrical issues (starter circuit, charging system, safety switches)
- Fuel system cleanup (old fuel, clogged lines, dirty tank)
Typical cost breakdown
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine (part only) | $200 to $1,400 | Varies by brand, HP, and shaft specs |
| Labor | $200 to $700 | Shop rate and complexity drive this |
| Fluids, filters, tune-up items | $30 to $150 | Oil, filter, spark plug, fuel filter |
| “While you’re in there” parts | $20 to $300 | Belts, idlers, wiring repairs |
Smart checks before you replace the engine
If the tractor will not start or runs poorly, we recommend ruling out common non-engine failures first:
- Verify battery condition and cable connections
- Confirm the PTO and safety interlock system is operating correctly
- Check for fuel delivery problems (stale fuel, clogged filter)
- Inspect wiring for damage and corrosion
- Listen for a click at the solenoid when turning the key; if not, test the starting circuit
If you are troubleshooting a no-crank condition, the starter solenoid is a common failure point; see lawn tractor starter solenoid 582042802.
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. A quick diagnosis using the wiring diagram and troubleshooting chart in the 917288610 owner’s manual helps you avoid replacing the engine when the real issue is electrical, fuel-related, or a safety switch problem.

What year did Craftsman make the 917288610?
Craftsman model 917288610 is a 26.0 HP, 54-inch deck front-engine lawn tractor (GT6000 series) covered by the Operator’s Manual for model 917.28861; that manual identifies the model but does not list a specific manufacturing year, so we date it by the tractor’s product/serial identification label and documentation revision details in the 917288610 owner’s manual.
How to find the exact year for 917288610
Use the tractor’s model and serial number label (typically under the seat, on the frame near the rear fender, or on the chassis rail). Then match the serial number format to the Craftsman build date information.
- Locate the model/serial label and write down the full serial number
- Check for a separate engine label (engine model and code can also indicate build date)
- Compare the serial number to the identification section in the 917288610 owner’s manual
- If the label is missing or unreadable, use the engine code date as a secondary reference
- Keep the serial number handy when ordering parts like a PTO switch or starter solenoid
Quick reference: what we can confirm from the manual
The Operator’s Manual excerpt confirms the configuration and model family, which helps narrow the era even when the exact year is not printed.
| Item | What we know for 917288610 | Where to verify |
|---|---|---|
| Model family | 917.28861 (same model line as 917288610) | Model/serial label, manual cover |
| Power/deck | 26.0 HP, 54" mower deck | Manual cover/spec section |
| Fuel guidance | Up to E10 gasoline | Manual fuel section |
Why it matters
The build year affects parts compatibility for common systems like the electric PTO clutch, steering linkage, and deck hardware. Confirming the serial number helps ensure you get the correct replacement the first time, especially for electrical parts such as the starter solenoid 582042802 or the switch.pto 582107601.

What engine does Craftsman riding mower use?
Craftsman riding mower model 917288610 uses a low-emission gasoline engine; the operator’s manual lists this tractor as a 26.0 HP, 54-inch mower configuration with electric start and an automatic transmission. For the exact engine make and model on your unit, use the engine ID tag and the engine section in the 917288610 owner’s manual.
How to identify the exact engine on your 917288610
The most reliable way to name the engine (and buy the right tune-up parts) is to read the engine’s identification label.
- Look for an engine model/spec and serial label (or stamped ID)
- Common locations: blower housing, valve cover, near the starter, or under the hood
- Record every character exactly (letters and numbers)
- Use that ID when ordering engine parts like spark plugs, air filters, and fuel filters
- Cross-check operating specs (oil type, capacity, maintenance intervals) in the 917288610 owner’s manual
What the manual confirms for this model
These are the model-level engine details called out in the manual for 917288610:
- 26.0 HP rating (as rated by the engine manufacturer)
- Low-emission engine design
- Gasoline with up to 10% ethanol (E10) is acceptable
- 54-inch mower configuration
Quick reference
| Item | What to use for 917288610 |
|---|---|
| Tractor identification | Model number 917288610 |
| Engine identification | Engine model/spec/serial from the engine ID tag |
| Fuel guidance | Gasoline up to E10 |
Why it matters
The tractor model number identifies the chassis and deck, but the engine ID determines the correct engine-specific parts and service specs. Using both prevents mismatches when buying maintenance items or troubleshooting starting and running problems.

What size deck is a Craftsman 917288610?
The Craftsman model 917288610 is equipped with a 54-inch mower deck (often listed as a 54" mower). This deck size determines your cutting swath and also affects which blades, mandrels, and belt routing match your tractor.
How to confirm the deck size on your tractor
We recommend verifying the deck size using the model’s documentation and a quick physical check.
- Check the cover page and specifications in the 917288610 owner's manual
- Measure the cutting width from the left blade tip to the right blade tip (straight across)
- Confirm the deck is the mid-mount style used on this tractor
- Compare your deck’s blade count and layout to the diagrams in the manual
Common deck sizes vs what you have
| Deck size | Typical blade setup | What it means |
|---|---|---|
| 42-inch | 2 blades | Smaller deck, tighter maneuvering |
| 48-inch | 3 blades | Mid-size deck |
| 54-inch | 3 blades | Wider cut, faster mowing on open areas |
Why it matters for parts and repairs
Deck size is the key filter for ordering the correct mower-deck parts. A 54-inch deck commonly uses different blade lengths, belt routing, and spindle (mandrel) components than a 42-inch or 48-inch deck.
If you are chasing vibration, uneven cut, or a squeal from the deck, the spindle/mandrel area is a frequent wear point. For this model, a common related replacement is the lawn tractor mandrel housing 587819701.
Quick tips before ordering deck parts
- Match parts to model 917288610, not just the tractor series name
- Inspect the deck for a stamped size marking (some decks have one)
- Replace worn hardware when removing spindles (lock nuts often deform when tightened)
- Torque blade bolts to the specification listed in the manual
