Craftsman Garden Tractor 917276021 FAQs

Craftsman uses engines from multiple manufacturers, depending on the specific mower or tractor. For Craftsman model 917276021, the most reliable way to confirm the engine brand is to read the engine identification label and cross-reference it with the specifications section in the 917276021 owner's manual.

Engine brands Craftsman commonly uses

Across Craftsman riding mowers and lawn tractors, these engine makers are the most common:

  • Briggs & Stratton
  • Kohler
  • Kawasaki
  • Other OEM suppliers on select models and years

How to identify the engine brand on model 917276021

Use the engine’s own ID tag, not the tractor model tag. On most 25 HP class riders, the label is under the hood on the blower housing, valve cover, or near the starter.

  • Lift the hood and locate the engine ID label
  • Write down the engine brand plus the model and spec/type numbers
  • Use those engine numbers when ordering engine-only parts (air filter, oil filter, spark plug, carburetor parts)
  • Use 917276021 when ordering tractor parts (deck, steering, belts, electrical)

“Mowemission” in the manual: what it means

The manual notes this tractor has a “mowemission” engine; that wording indicates an emissions-compliant engine configuration, not a specific engine brand.

Why it matters

Correct identification prevents wrong-part returns: engine numbers match engine parts, while the tractor model number matches chassis and deck parts.

Quick reference: which number to use

What you’re replacing Use this identifier Example items
Engine components Engine model/spec from the engine label Filters, plugs, carb parts
Tractor and deck components Craftsman model 917276021 Belts, blades, switches

Parts tip (tractor-side)

If the deck will not engage, a failed PTO switch is a common cause; the tractor uses a dedicated switch such as switch.pto 582107601.

Last updated: February 2026

The Craftsman riding mower model 917276021 uses a 25.0 HP mower-emissions gasoline engine on a 48-inch mower deck tractor with electric start and an automatic transmission. For the exact engine make and model (Briggs & Stratton, Kohler, etc.), use the engine ID label and the specs section in the 917276021 owner's manual.

What we know for Craftsman model 917276021

These model-specific details identify the engine setup and tractor configuration:

  • Horsepower rating: 25.0 HP
  • Emissions family/type: mower-emissions engine (outdoor power equipment compliant)
  • Starting system: electric start
  • Drive system: automatic transmission
  • Mower deck size: 48-inch

How to identify the exact engine make and model on your tractor

The engine manufacturer and model code are printed on the engine itself; that is the definitive identifier for parts and service.

  • Look on the engine shroud/blower housing for a sticker or stamped tag
  • Check near the valve cover or starter area for a model-type code
  • Record the model, type, and code (or spec number) exactly as shown
  • Match that information to the engine specifications and maintenance sections in the manual

Quick reference: what “kind of engine” can mean

What you mean by “kind” What to look for Why it’s used
Engine manufacturer and model Engine ID label Correct tune-up and repair parts
Cylinder configuration (single vs V-twin) Visual inspection, engine label Power feel, vibration, service differences
Fuel and emissions system Manual specs, engine label Proper fuel, choke/throttle use

Why it matters

Engine make and model control which air filter, spark plug, fuel filter, and service procedures fit your Craftsman 917276021. Using the engine ID prevents ordering the wrong maintenance parts and helps keep starting and mowing performance consistent.
