What engine does Craftsman riding mower use?
For Craftsman lawn tractor model 917275030, the owner’s manual identifies it as a 23.0 HP tractor with a low-emission engine. For the exact engine make, model, and service specifications (oil type, spark plug, air filter), use the 917275030 owner's manual.
How to identify the exact engine on your tractor
Even within the same tractor model, the engine brand and model are confirmed by the engine ID label (not the hood decal).
- Lift the hood and look for an engine label on the blower housing or valve cover
- Record the engine model, type, and code (or spec number)
- Match that information when buying tune-up parts (spark plug, air filter, fuel filter)
- If the label is missing, check the manual’s engine maintenance section for identification tips

Is it worth replacing a lawn mower engine?
Yes, replacing the engine on your Craftsman lawn tractor model 917275030 is worth it when the tractor’s deck, steering, and drive components are still solid and the total engine-swap cost stays well below the cost of a comparable replacement tractor. If the tractor also needs major deck or drive repairs, replacement usually makes more sense.
Quick decision checklist
- The mower deck is not rusted through or cracked
- The transmission and drive belt system operate normally (no slipping, grinding, or smoke)
- Steering and front axle feel tight (no severe wobble)
- You can do the work yourself or you are only paying for the engine, not extensive labor
- You plan to keep the tractor for several more seasons
Cost and condition guide
Use this as a practical rule-of-thumb when you compare an engine swap to buying another riding mower.
| What you see on the tractor | Typical recommendation | Why |
|---|---|---|
| Deck, frame, and driveline are in good shape | Replace the engine | You keep a known-good machine and avoid a full replacement purchase |
| Multiple systems are worn (deck issues plus steering plus electrical) | Replace the tractor | Costs stack up fast beyond the engine |
| Only small chassis parts are needed (caps, nuts, bearings) | Repair and keep it | Low-cost parts can restore reliability |
Related repairs to consider while the engine is out
An engine swap is the best time to handle easy-access wear items and safety checks.
- Inspect the blade drive system and idlers; a frozen idler can stop blades from rotating
- Check the PTO engagement; a failing switch can mimic engine or clutch problems (see switch.pto 582107601)
- Look over the fuel system for leaks and brittle lines; replace damaged tank fittings if needed
- Confirm safety interlock operation (seat switch, brake pedal switch, PTO disengaged) before first start
Why it matters
A new engine only pays off if the rest of the 917275030 tractor is safe and dependable. The manual emphasizes keeping safety devices working properly and making repairs with the engine off; that same mindset helps you avoid sinking money into a tractor that has bigger underlying issues.
Where to verify specs and procedures
For model-specific maintenance intervals, safety interlock behavior, and service procedures (like blade torque and seasonal tune-up items), use the owner's manual. For parts shopping beyond the items listed for this model, search by model number at Sears PartsDirect.

What year did Craftsman make the 917275030?
Craftsman model 917275030 was produced during the LT1000-era years; most tractors in this series were built in the early-to-mid 2000s. To identify the exact build year for your specific tractor, we use the serial number/date code on the tractor’s ID label as shown in the 917275030 owner's manual.
How to find the exact year on your tractor
On Craftsman riding mowers and lawn tractors, the most reliable way to date the unit is the product identification label (often under the seat or on the rear fender area). Use these checks:
- Look for the model and serial label under the seat pan or near the frame.
- Write down the serial number exactly as shown.
- Check the label for a manufacture date or a date code (some labels print it directly).
- If the label is worn, clean it gently and use a flashlight to read stamped characters.
- Match the model and key assemblies in the manual parts lists (electrical, chassis, steering) to confirm you are reading the correct label for 917275030.
What “917” means (and what it does not)
The 917 prefix is a Craftsman model family identifier used on many riding mower and lawn tractor models. It helps group similar designs, but it does not directly tell the exact year by itself.
Quick guide
| Item | What it tells you | What it does not tell you |
|---|---|---|
| Model number (917275030) | Series and configuration | Exact build date |
| Serial/date code on ID label | Exact build year (and often month/day) | Nothing about parts condition |
| Owner’s manual parts lists | Confirms correct model family | Exact build date |
Why it matters
The build year affects parts compatibility (wiring harnesses, PTO switch style, steering parts, belts) and helps us choose the correct replacement part the first time.
Parts that commonly vary by production run
- Ignition key and switch style (example: molded ignition key 532140403)
- PTO engagement components (example: switch.pto 582107601)
- Ground drive belt length and routing (example: lawn tractor lawn mower secondary v-belt 532137153)
- Steering linkage and wear items (example: drag link 532175572)
Ordering the right parts once you confirm the year
After you locate the serial/date code, order parts from the list for model 917275030, or search by model number on Sears PartsDirect if you are cross-checking additional diagrams.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman lawn tractor like model 917275030, a full engine replacement (parts plus labor) typically runs about $260 to $1,800 installed, with around 6 labor hours common for a riding mower engine swap. Exact cost depends on the engine type, any extra parts needed, and local labor rates.
What drives the total replacement cost?
Engine replacement pricing varies because the job often includes more than just the engine.
- Engine price range (new or replacement engine assembly)
- Labor time (commonly about 6 hours for riding mowers)
- Extra parts that get replaced “while we’re in there” (belts, pulleys, wiring)
- Fuel system cleanup if old fuel or debris caused the failure
- Deck and PTO condition (a worn clutch or belt can add cost)
Typical cost breakdown (what you’re paying for)
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part) | $200 to $1,500 | Varies by horsepower, shaft size, and brand compatibility |
| Labor | $200 to $700 | Based on shop rate and any seized fasteners or rust |
| Misc. parts and supplies | $20 to $200 | Fuel line clamps, oil, filter, hardware, shop supplies |
Before replacing the engine: quick checks that can save money
We recommend ruling out common “no start” causes first, especially if the engine clicks, spins, or dies under load.
- Verify the clutch/brake pedal is fully depressed and the PTO is disengaged (safety interlock)
- Check battery connections and starting circuit basics
- Inspect for fuel flow issues (a clogged in-line fuel filter can mimic engine failure)
- Confirm the PTO clutch is not binding the crankshaft when engaged
- Look for obvious mechanical damage (thrown rod, seized crank, heavy smoke)
If you need model-specific operating and safety interlock details, use the owner's manual.
Related parts that commonly come up during engine or drive repairs
Even when the engine is the main issue, we often see these parts involved in “won’t move” or “blades won’t engage” complaints:
- Lawn tractor lawn mower secondary v-belt 532137153 (ground drive belt)
- Switch.pto 582107601 (PTO switch)
- Lawn mower electric clutch 532174509 (electric PTO clutch)
- Lawn tractor idler pulley 532139245 (idler pulley)
Why it matters
Replacing an engine is one of the highest-cost repairs on a riding mower. Confirming the starting, fuel, and PTO systems first helps avoid paying for an engine when the real problem is a belt, clutch, switch, or safety interlock issue.
For ordering, you can use the parts list for model 917275030, or search by model number on Sears PartsDirect.

What model number is a Craftsman 6.75 lawn mower?
A “Craftsman 6.75” marking is not a model number; it is an engine power class used across many different Craftsman walk-behind mowers. The only way to identify the exact mower model is to read the model tag on the mower itself; for the riding tractor covered by this page, the model is 917275030 (see the 917275030 owner's manual).
Where to find the model number on a Craftsman 6.75 walk-behind mower
On most Craftsman walk-behind mowers, the model information is on the mower deck or rear housing, not on the engine shroud.
- Check the rear of the deck near the bagger door or discharge opening
- Look along the side of the deck near the rear wheel height adjuster
- Inspect the rear shield (behind the engine) for a sticker or metal tag
- Clean off grass and dirt so the full number is readable
- Write down the complete model number and any product/serial numbers shown
What the model number usually looks like
Craftsman walk-behind mower model numbers vary by series and year; they do not all start with the same prefix.
| What you see on the mower | What it identifies | What it is used for |
|---|---|---|
| “6.75” on the engine cover | Engine power class | Not enough to match mower parts |
| Engine model/type code (on engine label) | The engine itself | Engine parts (carb, filter, plug) |
| Mower model number (on deck/rear tag) | The mower configuration | Belts, wheels, blade, controls |
If you are actually working on Craftsman model 917275030 (riding tractor)
Model 917275030 is a front-engine lawn tractor (not a 6.75 walk-behind mower). Common parts on this tractor include the switch.pto 582107601 and the molded ignition key 532140403.
Why it matters
Using the mower’s exact model number prevents ordering the wrong blade, drive belt, wheels, or control parts; small design changes between models can require different parts.
