How much oil does a Craftsman riding lawn mower hold?
For the Craftsman garden tractor model 917276101, the engine oil capacity is typically about 2 quarts (64 oz) when you include the oil filter. For the exact fill amount and the correct oil type for your specific engine, follow the specs in the 917276101 owner's manual.
How we recommend filling the oil correctly
Overfilling can cause smoking and leaks; underfilling can damage the engine. Use this approach for the most accurate level:
- Park on a flat surface and set the parking brake
- Let the engine cool, then remove the dipstick and wipe it clean
- Add oil in small amounts (about 1/4 quart at a time)
- Recheck the dipstick after each addition
- Stop when the oil reaches the FULL mark (do not exceed it)
- Run the engine briefly, shut it off, wait 1 to 2 minutes, then recheck
Quick capacity guide (what to expect)
These are the most common capacities customers see on riding mowers and garden tractors like this one.
| Setup | Typical oil capacity |
|---|---|
| Oil change (no filter) | ~1.5 to 1.75 quarts |
| Oil change (with filter) | ~2.0 quarts |
Why it matters
Correct oil level protects the crankshaft, piston, and valve train, and it also helps the engine run cooler under load (especially when mowing thick grass with a 54-inch deck).

What engine does Craftsman riding mower use?
The Craftsman garden tractor model 917276101 uses a low-emission engine (as noted in the 917276101 owner's manual). This model is a 25.0 HP, 54-inch mower tractor; the exact engine brand and model are identified on the engine label and in the specifications section of the manual.
How to identify the exact engine on your 917276101
Use these quick checks to match parts correctly (air filter, spark plug, fuel filter, starter, and more):
- Look for the engine ID label on the blower housing, valve cover, or near the starter
- Record the engine model, type, and code exactly as printed
- Compare that information to the Product specifications section in the 917276101 owner's manual
- If the tractor has been serviced before, confirm the engine label still matches the tractor
- Use the engine ID (not just horsepower) when ordering tune-up parts
Common engine details you will see (what they mean)
| Label item | What it tells you | Why you need it |
|---|---|---|
| Model | Engine family/series | Primary identifier for parts lookup |
| Type | Configuration/build | Narrows down compatible components |
| Code | Build date/version | Helps match revisions and updates |
Why it matters
Craftsman tractors in the 917-series can use different engines across similar-looking units. Using the engine label prevents ordering the wrong maintenance parts and helps when troubleshooting starting, charging, or PTO engagement issues.
Related part and system notes (helpful when diagnosing)
If you are troubleshooting blade engagement rather than the engine itself, the PTO circuit is a common checkpoint. On this model, the attachment clutch switch engages the mower blades; a failed switch can mimic an engine power issue. If needed, match your replacement to the correct tractor part, such as the switch.pto 582107601.

Where to find the model number on the tractor
We use the model number to match the correct parts diagrams and replacement parts (like the ignition key, PTO switch, and steering hardware).
- Check the model tag/ID label on the tractor frame (commonly under the seat area or near the rear fender pan)
- Look for a line that says Model No. 917.276101
- Write down the full number exactly as shown (including any dots)
- If the label is dirty, wipe it clean so every digit is readable
- Use the model number when ordering parts such as a belt, mandrel assembly, or electrical switch
917.276101 vs. 917276101: what’s the difference?
They refer to the same tractor; the dot is just formatting.
| How it may appear | What it means | Use this when ordering parts? |
|---|---|---|
| 917.276101 | Printed format used in manuals/labels | Yes |
| 917276101 | No-dot format used in many parts systems | Yes |
Why it matters
Craftsman tractors in the 917 series can look similar, but parts like the deck drive system and electrical components vary by exact model. Using 917276101 helps ensure you get the right items, such as the switch.pto 582107601 or the correct ignition harness.

How much does it cost to replace a riding lawn mower engine?
For a Craftsman riding mower like model 917276101, a complete engine replacement typically runs about $260 to $1,800 installed, with labor commonly around 6 hours depending on shop rates and how much transfer work is needed (wiring, pulleys, exhaust, and fuel system). See the 917276101 owner's manual for maintenance items that can help you avoid premature engine damage.
What drives the total price
- Engine type and horsepower (OEM-spec vs. aftermarket equivalent)
- Labor rate (local shop hourly rate times estimated hours)
- Extra parts discovered during swap (belts, wiring, fuel line parts, muffler)
- Deck and PTO condition (a failing PTO system can add time and cost)
- Pickup and delivery fees (common for riding mowers)
Typical cost breakdown (installed)
| Cost item | Typical range | Notes |
|---|---|---|
| Replacement engine | $200 to $1,400 | Biggest variable; depends on spec match |
| Labor | $200 to $600 | Often based on ~6 hours for riding mowers |
| Misc. parts and supplies | $20 to $200 | Fuel filter, clamps, hardware, shop supplies |
| Estimated total | $260 to $1,800 | Matches common industry pricing |
Before you replace the engine, check these common causes
Many “bad engine” complaints are fuel, ignition, or overheating related. Our manual for this tractor calls out maintenance that directly affects engine life.
- Cooling fins and shrouds: grass buildup or missing shrouds can cause overheating and engine damage
- Fuel filter: replace once each season; a clog can restrict fuel flow
- Spark plug: replace at the start of each mowing season or every 100 hours
- Loose fasteners and V-belts: routine checks can prevent secondary damage
- Battery and charging system: poor connections can mimic bigger problems
Why it matters
An engine swap is one of the highest-cost repairs on a riding mower. Following the maintenance schedule (oil, cooling system cleaning, fuel filter, spark plug) helps prevent overheating and fuel starvation issues that shorten engine life. The 917276101 owner's manual also includes a troubleshooting chart that can help you rule out simpler fixes first.
