Craftsman 917276021 garden tractor Parts

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.
