Key Components of Craftsman Self-Propelled Lawn Mower Parts
1. Drive Wheels and Axles
The drive wheels are what propel the mower forward. They are mounted on axles connected to the transmission system. These wheels are typically made of durable rubber with treads designed for traction on various terrains. Over time, wear and tear can cause the wheels to become cracked, bald, or loose, necessitating replacement parts.
2. Transmission System
The transmission system is responsible for transferring power from the engine to the drive wheels. Craftsman mowers may feature different types of transmissions, such as:
- Variable speed transmissions: Allow for adjustable speed control.
- Automotive-style transmissions: Use belts and pulleys to transfer power.
Common parts include:
- Transmission housing
- Clutch assembly
- Drive gears
3. Drive Belts and Pulleys
Drive belts connect the engine pulley to the transmission pulley, transmitting rotational power to move the wheels. Proper tension and condition of these belts are crucial for smooth operation. Over time, belts can stretch, crack, or fray, requiring replacement.
- Drive belt: Usually made of reinforced rubber or neoprene.
- Idler pulleys: Guide and maintain belt tension.
4. Control Levers and Linkage
Control levers allow the operator to engage or disengage the self-propelled feature. They are connected via linkage to the drive system components. Common parts include:
- Drive control cable
- Clutch lever
- Throttle linkages
Ensuring these components are properly adjusted and lubricated helps maintain responsive control.
5. Engine and Power Source
The engine provides the power necessary for both cutting and propulsion. Craftsman uses various engine brands, such as Briggs & Stratton or Kohler. Key parts include:
- Engine assembly
- Flywheel
- Spark plug
- Recoil starter
Regular maintenance of the engine directly impacts the performance of the self-propelled system.
