Do Craftsman mowers use Briggs and Stratton engines?
Yes, Craftsman mowers can use Briggs & Stratton engines, and the Craftsman model 917275810 specifically is equipped with a Briggs & Stratton engine (listed in the engine section of the 917275810 owner's manual).
What this means for Craftsman 917275810 owners
On this model, engine-related maintenance and many tune-up parts are typically matched to the Briggs & Stratton engine model/type shown for the tractor, not just the tractor model number.
Common engine-related items you may service include:
- Spark plug (the manual lists Champion RC12YC with a .030 in gap)
- Air filter and pre-cleaner
- Fuel filter
- Engine oil and (if equipped) oil filter
- Muffler and spark arrester (if equipped)
How to confirm the engine brand on other Craftsman mowers
Craftsman has used multiple engine suppliers across different mower lines and years, so the engine brand is best confirmed by checking the engine label on the blower housing or valve cover.
Look for:
- Engine manufacturer name (Briggs & Stratton, Kohler, etc.)
- Engine model and type code
- Emissions label information
Quick comparison
| What you check | Where to look | Why it helps |
|---|---|---|
| Tractor model number | Frame tag (often under seat or on frame) | Identifies the mower/tractor platform |
| Engine model/type | Engine label on the engine | Identifies the correct engine parts and specs |
| Owner’s manual | 917275810 owner's manual | Confirms specs like oil type, spark plug, and maintenance intervals |
Related parts that can matter during maintenance
If you are doing a seasonal tune-up or chasing a performance issue, deck and drive components can also affect how the tractor feels under load.
Examples for this model include:
- A worn blade drive belt can slip and reduce cutting performance
- Dull or damaged blades can strain the engine and leave a poor cut
If you are servicing the deck, a common replacement item is the lawn tractor v-belt 532144959 (blade drive belt).
Why it matters
Knowing whether your Craftsman mower uses a Briggs & Stratton engine helps you choose the correct maintenance parts and follow the right specifications (oil type/viscosity, spark plug type and gap, fuel recommendations), which directly affects starting, power, and engine life.

What kind of oil do you use in a Craftsman lawn tractor?
For Craftsman lawn tractor model 917275810, use SAE 30 engine oil when operating above 32°F, and SAE 5W-30 when operating below 32°F. Use a high-quality detergent 4-cycle oil that meets API service SG-SL (see the 917275810 owner's manual).
Oil type and temperature guide (model 917275810)
This model’s manual lists two acceptable viscosity grades based on outdoor temperature.
| Outdoor temperature | Recommended oil viscosity | Notes |
|---|---|---|
| Above 32°F | SAE 30 | Best for warm-weather mowing |
| Below 32°F | SAE 5W-30 | Helps cold starting and lubrication |
What to buy (quick checklist)
When you’re shopping for oil for the 917275810, look for:
- 4-cycle engine oil (never 2-cycle mix)
- SAE 30 or SAE 5W-30 (based on temperature)
- API SG-SL rating (or stated as meeting/exceeding it)
- A reputable brand formulated for small engines
- Enough oil for a full change (capacity varies depending on whether an oil filter is installed)
Capacity notes for this model
The 917275810 manual lists these approximate capacities:
- With oil filter: 3.5 pints
- Without oil filter: 3.0 pints
Because some engines are equipped differently, we recommend confirming whether your tractor has an oil filter before filling to capacity.
Why it matters
Using the correct viscosity helps your Briggs and Stratton 4-cycle engine maintain proper oil pressure and cooling. Oil that’s too thick in cold weather can make starting harder; oil that’s too thin for conditions can increase wear.
