What engine does Craftsman riding mower use?
The Craftsman riding mower model 917275285 uses a gasoline engine; the exact engine brand and horsepower are identified on the engine ID label and in the 917275285 owner's manual. Use those identifiers to match tune-up parts (filter, spark plug, belts) and ensure correct service specs.
Check these common locations for the engine model and type code:
- Valve cover or blower housing sticker
- Engine shroud near the recoil or electric starter area
- Above the muffler or near the dipstick tube
- Stamped tag near the flywheel screen
- Frame tag under the hood (sometimes lists engine family)
Write down the full engine model and type numbers before ordering parts.
Many Craftsman front-engine lawn tractors in this series commonly use a single-cylinder, vertical-shaft gasoline engine (often from Briggs & Stratton or a similar OEM supplier). The mower deck and drive system are matched to that engine’s output, so using the engine ID is the reliable way to confirm horsepower and service parts.
| What you need | Where to find it | Why it matters |
|---|---|---|
| Engine model/type code | Engine label/tag | Correct carburetor and ignition parts |
| Horsepower or displacement | Engine label/manual | Proper tune-up and performance expectations |
| Oil type and capacity | Manual/engine label | Prevents hard starting and engine wear |
| Air filter style | Filter housing | Ensures correct fit and airflow |
The engine model determines critical maintenance specs (oil viscosity, spark plug gap, air filter style) and helps you avoid ordering the wrong parts for your Craftsman tractor.

Is it worth replacing a lawn mower engine?
Yes, it’s worth replacing the engine on your Craftsman garden tractor model 917275285 when the mower deck, frame, steering, and transmission are still solid and the total engine swap cost stays well below the cost of a comparable replacement tractor. If the tractor has multiple major worn systems, replacement usually makes more sense.
- The deck shell is not rusted through and the spindles turn smoothly
- The transaxle drives strong (no slipping, whining, or loss of pull)
- Steering and front axle are tight enough to track straight
- You can do the work (or pay labor) without pushing the total cost too high
- You want to keep your current attachments and setup
We use this guideline for riding mowers and tractors:
| If total repair cost is… | Typical recommendation |
|---|---|
| Under ~30% of a comparable new tractor | Replace the engine (good value) |
| ~30% to 50% | Replace if the chassis and deck are in great shape |
| Over ~50% | Put the money toward a replacement tractor |
“Total repair cost” should include the engine, any required mounting parts, belts, blades, battery, and labor.
Use the 917275285 owner’s manual to confirm maintenance points and basic specs, then inspect these high-failure areas:
- Deck drive system: belt condition, idler pulleys, and engagement feel
- Blade system: vibration, bent blades, and worn mandrels
- Fuel system: stale fuel damage, cracked lines, and tank fittings
- Electrical: safety switches, PTO switch function, and wiring condition
If your deck won’t engage reliably, a failed PTO switch can mimic bigger problems; the pto switch 582107601 is a common electrical wear item.
An engine swap can reset reliability and extend the life of a good Craftsman chassis, but it does not fix worn deck hardware, weak transaxles, or unsafe steering. Checking those systems first prevents spending engine money on a tractor that still won’t mow well.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding mower like model 917275285, a full engine replacement typically costs $260 to $1,800 installed, depending on the engine type, labor rates, and whether you replace related wear items at the same time. Most shops book around 6 labor hours for a riding mower engine swap.
- Engine price: new, rebuilt, or used engines vary widely in cost
- Labor rate: local shop rates and minimum charges can change the total quickly
- Extra parts: belts, pulleys, fuel parts, and hardware often get replaced during the job
- Condition of fasteners/wiring: rusted bolts, damaged harnesses, or seized pulleys add time
- Pickup and delivery: common add-on charge for riding mowers
| Cost item | Typical range | Notes |
|---|---|---|
| Engine (part) | $150 to $1,400 | Biggest variable; depends on brand, horsepower, and availability |
| Labor | $110 to $600 | Often based on about 6 hours total |
| Fluids, tune-up items, misc. | $0 to $200 | Oil, filter, clamps, fuel line, spark plug |
| Optional related repairs | $0 to $400+ | Deck drive, pulleys, wiring, battery |
We recommend confirming the engine is truly the root problem before investing in a replacement.
- Verify the battery and charging system are healthy
- Check for spark and fuel delivery issues
- Inspect the PTO circuit if the mower dies when engaging blades
- Look for low compression (common sign of internal engine wear)
- Review the correct engine specs and mounting details in the 917275285 owner’s manual
If you are already doing major work, it often makes sense to address deck-drive wear items at the same time.
- Pto switch 582107601 (if the PTO engagement is intermittent)
- Husqvarna lawn tractor primary blade drive belt, 5/8 x 90-3/32-in 532174368 (if cracked, glazed, or stretched)
- V-groove idler pulley 532193195 (if noisy, wobbly, or seized)
- Fuel line and clamps (as needed)
An engine replacement can cost close to the value of an older riding mower. Pricing the job with labor and the most likely companion parts helps you decide whether to repair, repower, or replace the tractor.
