What kind of engine does a Craftsman riding lawn mower have?
For the Craftsman CMXGRAM1130036 (T100 series) riding lawn mower, the exact engine make and horsepower are not identified in the model’s operator documentation; the manual directs you to the separate engine manual for the engine series, oil type, and oil capacity. See the CMXGRAM1130036 operator’s manual.
We recommend confirming the engine details from the engine label (usually on the blower housing or valve cover) and matching it to the separate engine manual.
- Look for the engine model/type/code stamped or printed on the engine
- Record the engine series and serial number
- Match that information to the correct Briggs & Stratton (or other brand) engine manual
- Use the engine model to buy the correct spark plug, air filter, and oil filter
- If you’re troubleshooting fuel delivery, start with the fuel filter 394358S
The operator’s manual for this T100 series tractor confirms fuel type and points you to the engine manual for engine-specific specs.
| Item | What we can confirm for CMXGRAM1130036 | Where to verify details |
|---|---|---|
| Fuel type | Unleaded gasoline | Operator’s manual |
| Engine series | Not specified in the tractor manual | Separate engine manual / engine label |
| Oil type and capacity | Not specified in the tractor manual | Separate engine manual / engine label |
Using the correct engine identification prevents wrong maintenance parts and incorrect oil selection, which can cause hard starting, poor performance, or premature engine wear.

Is it worth replacing a lawn mower engine?
Yes, it can be worth replacing the engine on your Craftsman CMXGRAM1130036 T110 lawn tractor when the tractor is otherwise in good shape and the repair restores reliable starting and power. If the total engine swap cost approaches about half the tractor’s replacement value, replacement is usually the better buy.
- The deck, steering, and transmission drive normally (no major slipping or grinding)
- The frame is solid (no cracks, severe rust-through, or bent mounting points)
- You can confirm the correct engine spec and mounting pattern for CMXGRAM1130036
- You are not also facing multiple big-ticket repairs (deck spindles, wiring harness, transmission)
- You can do the work safely (fuel handling, lifting, and belt routing)
Use this table to decide based on total cost, not just the engine price.
| Item to compare | What to include | Why it matters |
|---|---|---|
| Engine replacement total | Engine, shipping, hardware, oil, filters, labor | This is the real out-the-door cost |
| Tractor replacement cost | New tractor price, delivery, tax | Sets your “walk-away” number |
| Remaining tractor condition | Deck, belts, tires, battery, wiring | A weak platform makes a new engine a short-term fix |
Even if you replace the engine, we recommend addressing common fuel-related causes first, because they are cheaper and can mimic engine failure.
- Replace the fuel filter if fuel flow is restricted: fuel filter 394358S
- Drain stale fuel and refill with fresh unleaded gasoline (87+ octane)
- Inspect the fuel line for blockage or cracking
- Check spark plug condition and gap (per the separate engine manual)
A riding mower engine swap is a high-effort repair. If the rest of the CMXGRAM1130036 tractor is solid, a new engine can extend useful life significantly; if other major systems are worn, you can end up chasing repairs after spending the most on the engine.
This tractor’s operator manual covers multiple T100-series models and refers engine details (oil type, oil capacity, and engine series) to a separate engine manual. Use the CMXGRAM1130036 manual to confirm operating and service checks, then match the replacement engine to your exact engine model and mounting configuration.

What brand engine does Craftsman use?
For the Craftsman CMXGRAM1130036 T110 lawn tractor, the operator’s manual does not name a specific engine brand; it directs you to the separate engine manual and the engine ID label for the manufacturer and exact engine series. Use the CMXGRAM1130036 instruction manual to confirm where the engine identification information is referenced.
The CMXGRAM1130036 tractor manual is a multi-model T100 Series manual and lists these engine-related items as “See Separate Engine Manual,” rather than specifying a brand:
- Engine series
- Engine oil type
- Engine oil capacity
It does specify the fuel type for the tractor:
- Unleaded gasoline
- 87 or higher octane
- Fresh fuel (the manual recommends no more than 30 days old)
Check the engine itself for the manufacturer label and model/type code. Common locations include:
- Blower housing or engine shroud
- Valve cover area
- Near the starter or recoil housing
- Near the muffler heat shield
- A metal tag or sticker on the engine
Once you have the engine make and model/type code, you can match maintenance parts correctly, such as a fuel filter.
If you’re servicing the fuel system, use the engine identification to confirm compatibility before ordering a replacement like the fuel filter 394358S.
| Item you’re replacing | Why the engine ID matters | What to match |
|---|---|---|
| Fuel filter | Hose size and flow direction vary by engine | Engine model/type code |
| Spark plug | Heat range and thread reach vary | Engine spec label |
| Oil filter (if equipped) | Thread and gasket size vary | Engine manual listing |
Craftsman is the equipment brand; the engine manufacturer and engine model determine the correct oil specs and tune-up parts. Matching parts to the engine ID helps prevent hard starting, poor performance, and premature wear.
