Main Components of the 6.75 Craftsman Lawn Mower
The primary parts of the lawn mower can be categorized into engine components, cutting system parts, drive system parts, and safety features. Here's a detailed breakdown:
Engine Parts
The engine is the heart of the mower, powering the blades and movement. Key engine parts include:
- Carburetor: Mixes air and fuel for combustion. Problems here can cause starting issues or rough running.
- Spark Plug: Ignites the fuel-air mixture. Worn or dirty spark plugs lead to misfires or difficulty starting.

Drive and Transmission Parts
These parts control the mower's movement:
- Drive Belt: Transfers power from the engine to the wheels. Worn belts can slip or break, hindering movement.
- Drive Wheels and Axles: Enable the mower to move forward or backward. Damaged wheels affect maneuverability.
- Transmission System: Some models have variable speed controls or self-propulsion features.
Safety and Control Components
Ensuring safety is paramount:
