Do Craftsman mowers use Briggs and Stratton engines?
Yes, some Craftsman mowers use Briggs and Stratton engines. For the Craftsman lawn tractor model 917273752, the owner's manual identifies a Briggs engine model 31P777 (type 0299-E1), so this specific tractor is Briggs-powered.
What this means for parts and service
Engine brand matters most when you’re buying tune-up parts (spark plug, air filter, carburetor parts) or looking up engine-specific specs.
- Use the tractor model (917273752) to find chassis and deck parts (belts, blades, mandrels, steering).
- Use the Briggs engine model (31P777) when ordering engine-internal parts or engine gasket sets.
- Match the engine type number when possible; it narrows down exact variations.
- Follow the maintenance intervals and oil recommendations in the manual.
Where to confirm your engine model on the tractor
We recommend verifying the engine ID label on the engine shroud or valve cover area; it should list the Briggs model and type.
- Look for a sticker or stamped tag that includes “MODEL” and “TYPE”.
- Clean off grass and oil film so the numbers are readable.
- Record both the model and type before ordering engine parts.

How much does it cost to replace a riding mower engine?
Replacing the engine on a Craftsman lawn tractor model 917273752 typically costs $800 to $2,500 total for parts and professional labor; a DIY swap is usually $500 to $1,800 for the engine alone. Your exact total depends on engine specs, labor rates, and any worn belts or pulleys replaced at the same time.
Typical cost breakdown
Most of the cost is the engine; labor and small parts can add up quickly.
- Replacement engine: $500 to $1,800
- Labor (shop install): $300 to $900
- Fluids and tune-up items: $25 to $150
- Pickup/delivery (if used): $50 to $200
- Common “while you’re in there” parts: belts, idlers, wiring repairs, battery
Common scenarios
| Scenario | What you pay for | Typical total |
|---|---|---|
| DIY engine swap | Engine only (you install) | $500 to $1,800 |
| Shop replacement | Engine + labor | $800 to $2,500 |
| Engine + multiple wear parts | Engine + labor + belts/pulleys/battery | $1,200 to $3,000 |
What to confirm before you buy an engine
To avoid fitment problems on model 917273752, match the new engine to the old one’s key specs.
- Crankshaft diameter and length (PTO end)
- Mounting bolt pattern and crank height
- Charging system output and connector style
- Throttle/choke linkage setup
- Muffler/exhaust routing and heat shielding
For the correct procedures and safety steps (parking brake, blade disengagement, key removal), use the 917273752 owner’s manual.
Parts that often get replaced at the same time
If the old engine failed from age, heat, or vibration, these related parts are often worn too:
- V-belt 532138255 (ground drive belt)
- Blade(s) if cut quality has been poor
- Battery cables and terminals if cranking has been weak
Why it matters
A correctly matched engine prevents PTO alignment issues, belt tracking problems, and wiring/charging mismatches; that protects the new engine and helps the tractor mow and drive correctly.

How to find Craftsman model number?
On a Craftsman riding mower, we typically find the model number on a product ID label under the seat area. For your Craftsman lawn tractor, the model number you will use for parts lookup is 917273752; confirm the exact label location and format in the 917273752 owner's manual.
Where to look on the tractor
Check these common label locations first (clean the area so the numbers are readable):
- On the frame under the seat
- On the underside of the seat pan
- Near the rear fender or seat support bracket
- Around the engine compartment frame rails
- Near the transaxle area on the frame
What numbers to write down (and why)
We recommend recording all of the following from the label so you get the right diagrams and parts the first time:
- Model number (example for this tractor: 917273752)
- Serial number (helps identify production run changes)
- Product number (sometimes shown on outdoor power equipment labels)
Quick ID guide
| Label item | What it does | When it matters most |
|---|---|---|
| Model number | Identifies the exact tractor design | Always, for parts diagrams |
| Serial number | Identifies the build sequence | When parts changed mid-run |
| Engine model/type/code | Identifies the engine itself | Engine tune-up and fuel system parts |
Why it matters
Craftsman tractors often share similar frames and 42-inch mower decks across multiple models, but belts, blades, electrical parts, and steering components can vary by model and serial range. Using the correct model number (and serial number when available) prevents ordering the wrong blade, V-belt, or ignition parts.

What are the parts of a lawn mower engine?
On the Craftsman lawn tractor model 917273752, the engine is built from a few core systems: fuel delivery, air intake, ignition, internal rotating parts, and exhaust. Knowing these main engine parts helps us diagnose common issues like loss of power, hard starting, and rough running using the 917273752 owner's manual.
Main lawn tractor engine parts (what they do)
- Fuel tank: stores gasoline for the engine.
- Fuel filter and fuel line: keeps debris and water out of the carburetor.
- Carburetor: mixes fuel and air; mixture may need adjustment in cold weather or high altitude.
- Air filter and air screen/fins: keeps dirt out and helps cooling.
- Ignition system (spark plug and ignition coil): creates spark to ignite the fuel mixture.
- Flywheel: helps the engine run smoothly and supports ignition timing.
- Crankcase, crankshaft, piston, and valves: the internal parts that create power.
- Muffler: reduces noise; a clogged muffler can cause power loss.
Quick troubleshooting: which “engine part” is often involved?
The manual’s troubleshooting chart points to these common engine-related causes:
- Dirty air filter (hard starting, loss of power)
- Stale/dirty fuel or water in fuel (rough running, no-start)
- Loose spark plug wire or faulty spark plug (misfire, no-start)
- Dirty engine cooling fins/air screen (overheating, power loss)
- Carburetor out of adjustment (poor performance, especially in cold weather)
Engine vs. mower deck parts (common mix-up)
Some problems feel like “engine trouble” but come from the cutting system.
| If you notice | Often the cause is | Example part on this model |
|---|---|---|
| Excessive vibration | Bent/worn blade or mandrel issue | Husqvarna lawn tractor mandrel assembly 532130794 |
| Poor cut, uneven | Deck not level, buildup under deck | Deck leveling and cleaning steps in the manual |
| Loss of power while mowing | Cutting too much grass too fast, airflow restriction | Air filter, cooling fins, mowing technique |
Why it matters
When we identify the system first (fuel, air, ignition, or internal engine), we avoid replacing the wrong parts and we get to the real fix faster, especially for symptoms like loss of power and won’t start.
