What are the parts of a tractor engine?
On Craftsman lawn tractor model 917272244, the engine is built from several major systems: the internal rotating parts that make power, the head and valve train that controls compression, plus fuel, starting, lubrication, and exhaust components. For the exact illustrated breakdown for your tractor, use the 917272244 owner's manual.
Main engine systems and common parts
Most front-engine lawn tractor engines (including the engine shown in the 917272244 parts diagrams) include these groups:
- Crankcase and breather: crankcase, breather cover, seals, gaskets
- Rotating assembly: crankshaft, connecting rods, pistons, piston rings
- Head and valve train: cylinder head, valves, lifters, push rods
- Fuel system: carburetor, fuel line, hose clamps, fuel tank, fuel cap
- Starting system: starter motor, starter solenoid, pinion drive, wiring connections
- Exhaust: muffler, exhaust pipes, exhaust gasket, heat shield
- Lubrication: oil pan, drain tube or drain plug, oil seals
Examples called out for model 917272244
The 917272244 manual’s engine sections show typical service parts such as:
- Throttle and choke controls and linkage
- Muffler and exhaust gaskets
- Fuel tank, cap, fuel line, and clamps
- Starter solenoid and starter drive components
- Crankshaft and crankcase-related seals and gaskets
Quick reference: engine parts by function
| Engine function | Common parts you will see | What it affects |
|---|---|---|
| Makes power | crankshaft, pistons, connecting rods | compression and torque |
| Controls RPM and starting | throttle linkage, choke parts | cold starts, speed control |
| Delivers fuel | carburetor, fuel line, clamps, tank/cap | surging, stalling, no-start |
| Cranks the engine | starter, solenoid, pinion drive | no-crank, slow-crank |
| Routes exhaust | muffler, pipes, gaskets, heat shield | noise, fumes, power loss |
Why it matters
When you group parts by system, troubleshooting gets faster. A no-crank points to the starting system, while fuel starvation points to the carburetor or fuel line, and loud operation often points to the muffler or exhaust gasket.

What kind of engine does a Craftsman riding lawn mower have?
For Craftsman lawn tractor model 917272244, the owner’s manual specifies a 20.0 HP engine with electric start (this is the engine rating used for this tractor’s operation and maintenance specs). For the exact engine make and model, use the identification steps in the 917272244 owner's manual.
How to identify the exact engine brand and model
Most riding mower engines have an ID label on the engine shroud or valve cover. We use that label to match tune-up and repair parts correctly.
- Turn the ignition switch OFF and remove the key
- Let the engine and muffler cool completely
- Lift the hood and locate the engine model/type/code label
- Write down the full string (letters and numbers)
- Match parts by the engine ID, not just the tractor model number
What the manual tells you about this tractor’s engine setup
Based on the manual for model 917272244, this tractor is configured as follows:
| Spec item | What you can expect on 917272244 |
|---|---|
| Engine output | 20.0 HP |
| Starting system | Electric start |
| Tractor type | Front-engine lawn tractor |
Why it matters
Engine brand and model determine the correct spark plug, air filter, fuel filter, and oil type. Using the tractor model alone can lead to ordering the wrong maintenance parts, even when the mower deck and chassis parts match.
Related maintenance tip
For best mowing performance and battery charging, we follow the manual guidance to run at full throttle during mowing and avoid leaving the key on when the engine is off (that can discharge the battery). See the operating section in the 917272244 owner's manual.

What model number is the Craftsman 917272244 engine?
For Craftsman lawn tractor model 917272244, the engine identification you need is the engine’s model and type code from the engine ID label, not the tractor model number. Our 917272244 owner's manual shows the tractor model; use the engine tag to get the exact engine model.
How to identify the engine model on a 917272244
Look for the engine manufacturer ID label (often a sticker or stamped plate) on the engine itself.
- Park on level ground, set the parking brake, remove the key
- Let the engine cool completely
- Lift the hood and locate the engine ID label
- Common label locations: blower housing, valve cover area, near the starter, or on the shroud
- Write down every field shown (model, type, code, and sometimes serial)
- Use that full ID when ordering engine parts (air filter, spark plug, carburetor parts)
Tractor model vs. engine model (what’s what)
| ID you’re looking at | Example for this unit | What it’s used for |
|---|---|---|
| Tractor model number | 917272244 | Chassis, mower deck, steering, belts, electrical layout |
| Engine model/type code | From the engine ID label | Tune-up parts and engine-specific replacement parts |
Why it matters
Craftsman tractors can be built with different engine versions over time. The engine ID label locks in the exact engine configuration so you get the correct parts the first time.

What year is my Craftsman mower serial number lookup?
The year of a Craftsman mower is determined by the serial number format on the ID tag, and that format varies by production run. For Craftsman lawn tractor model 917272244, use the ID tag information and the identification section in the 917272244 owner's manual to confirm where the tag is and what numbers to record.
Where to find the model and serial tag
On most Craftsman riding mowers and lawn tractors, the ID tag is commonly found in one of these places:
- Under the seat pan or on the seat support
- On the frame near the rear wheels
- Under the hood near the engine compartment
- Near the footrest area on the frame rail
How to decode the year from the serial number
Once you have the full serial number, use these practical checks to identify the date code pattern:
- Look for a date-like group of 6 digits (often read as MMDDYY or similar)
- Confirm the first two digits are 01 to 12 if you are testing an MMDDYY pattern
- Confirm the next two digits are 01 to 31 if you are testing a DD position
- If the tag lists a separate DOM (date of manufacture), use that as the build date
- If the serial includes letters, the date code may be embedded and not strictly the first 6 digits
Example of a common 6-digit date code
If you find a 6-digit group like 072811, it decodes as:
| Digits | Interpreted as | Result |
|---|---|---|
| 07 | Month | July |
| 28 | Day | 28 |
| 11 | Year | 2011 |
If the numbers do not fit a date
If the digits do not match valid month/day ranges, use these next steps:
- Re-check that you copied the serial number correctly (0 vs O, 1 vs I)
- Look elsewhere on the tag for a second number string that looks like a date
- Use the model number 917272244 plus the full serial number when ordering parts to ensure the correct diagrams and revisions
Why it matters
The build year helps us match the correct Craftsman parts for your 917272244, especially items that can vary by production run such as a pto switch 582107601 and drive or deck components.
