How do I identify my Craftsman lawn mower?
To identify your Craftsman riding lawn tractor, match the model number on the product identification label to your paperwork and parts listings. For this tractor, the operator’s manual shows model 917.28972 (commonly written as 917289720 on parts pages). See the 917289720 owner's manual for label location details.
Where to find the model and serial label
On most Craftsman front-engine lawn tractors, the product identification label is located under the seat area. Use these quick checks:
- Park on a flat surface, set the parking brake, and turn the key off
- Flip the seat forward and look on the underside of the seat or the seat pan area
- Write down the model number and serial number exactly as shown
- If the label is dirty, wipe it gently so all digits are readable
- Use the model number to select correct parts such as belts, pulleys, and switches
What numbers you should record (and why)
The model number identifies the tractor family; the serial number helps confirm production details when parts changed during a run.
| What to record | Example for this tractor | What it’s used for |
|---|---|---|
| Model number | 917289720 (may appear as 917.28972 in the manual) | Finding correct diagrams and parts |
| Serial number | (varies by unit) | Confirming exact configuration |
| Engine model/type | (on engine shroud/label) | Engine-specific tune-up parts |
Why it matters
Using the exact model number prevents ordering the wrong deck belt, PTO switch, or drive components. For example, belt routing and deck hardware can differ even between similar Craftsman tractors.
If you are troubleshooting starting issues while identifying the unit, use riding lawn mower engine clicks but doesnt turn over video to narrow down battery, solenoid, and safety switch causes.

How much oil does a Craftsman 917289720 take?
The Craftsman 917289720 lawn tractor takes 64 oz (2.0 qt) of engine oil with the oil filter installed, or 60 oz (1.9 qt) without the filter. These capacities and the recommended oil viscosities are listed in the 917289720 owner's manual.
Oil capacity and oil type (quick reference)
| Service situation | Oil capacity | Oil type (by temperature) |
|---|---|---|
| Change oil and replace filter | 64 oz (2.0 qt) | SAE 30 (above 32°F) or SAE 5W-30 (below 32°F) |
| Change oil only (no filter) | 60 oz (1.9 qt) | SAE 30 (above 32°F) or SAE 5W-30 (below 32°F) |
How we recommend filling it (avoid overfill)
- Park the tractor on level ground and let the engine cool.
- Drain old oil fully; replace the drain plug securely.
- If changing the filter, install the new filter per the manual.
- Add about 3/4 of the listed capacity first.
- Check the dipstick, then top off slowly to the full mark.
- Run the engine briefly, shut it off, wait 1 to 2 minutes, then recheck.
Why it matters
Using the correct oil capacity prevents low-oil wear and also prevents overfilling, which can cause smoking, plug fouling, and leaks. Matching viscosity (SAE 30 vs. SAE 5W-30) improves lubrication and cold-weather starting.

What are the parts of a tractor engine?
A tractor engine is built from a few core systems that work together: the rotating assembly (crankshaft, pistons, connecting rods), the valve train (camshaft, valves), fuel and ignition, lubrication, cooling, and exhaust. For Craftsman model 917289720, the exact layout and service points are shown in the 917289720 owner's manual.
Main engine assemblies you will hear referenced
- Cylinder block and cylinder head: the main castings that form the cylinders and combustion chamber
- Pistons, piston rings, and wrist pins: compress the air-fuel mixture and transfer force to the rods
- Connecting rods and crankshaft: convert up-and-down piston motion into rotating power
- Camshaft, lifters, pushrods, rocker arms, valves, valve springs: open and close the intake and exhaust valves
- Flywheel and starter system: helps start the engine and smooths rotation
- Exhaust system (muffler): routes exhaust gases away from the engine (many tractors also use a spark arrester)
Fuel, ignition, lubrication, and cooling parts (typical)
Even when brands vary, most riding mower engines use the same building blocks:
- Carburetor or fuel injection components, fuel lines, fuel filter, fuel tank
- Ignition coil, spark plug, ignition switch and safety interlocks
- Oil sump, oil pump (if equipped), oil filter (if equipped)
- Cooling fins and blower housing (air-cooled engines), plus shrouds/ducting
Quick reference: what each system does
| System | Key parts | What it affects |
|---|---|---|
| Rotating assembly | crankshaft, rods, pistons | power output, knocking, compression |
| Valve train | camshaft, valves, springs | starting, backfiring, power loss |
| Fuel/ignition | carburetor, spark plug, coil | no-start, surging, stalling |
| Lubrication | oil, filter, seals | engine wear, overheating |
| Exhaust | muffler, spark arrester | noise, power, safe operation |
Why it matters
When you can name the system (fuel, ignition, compression, or safety interlock), troubleshooting gets faster and you avoid replacing good parts. For example, a click-no-start is often electrical (battery, wiring, solenoid) rather than an internal engine failure.
