Major Components of Craftsman Tractor Mower Parts
1. Engine Parts
The engine is the heart of your lawn tractor, powering all other functions. Common engine parts include:
- Carburetor: Mixes air and fuel for combustion. A dirty or faulty carburetor can cause starting issues or rough running.
- Spark Plug: Ignites the fuel-air mixture. Worn or fouled spark plugs lead to misfires and poor performance.
- Oil Filter: Keeps the engine oil clean. Replacing it prevents engine wear.
- Air Filter: Prevents debris from entering the engine. A clogged air filter reduces efficiency.
- Recoil Starter: Used to manually start the engine. Worn pull cords or faulty mechanisms require replacement.
2. Cutting Deck Components
The cutting deck is responsible for mowing the grass and includes:
- Blades: The sharp, rotating knives that cut grass. Dull blades cause uneven cuts and stress on the engine.
- Spindles: Mount the blades and enable their rotation. Worn spindles can lead to wobbling or noise.
- Blade Belts: Drive the blades from the engine. Worn or broken belts reduce cutting efficiency.
- Deck Shell: The outer housing that protects the blades and grass discharge.
3. Transmission and Drive System
This system transmits power from the engine to the wheels and includes:
- Transaxle: Combines transmission and axle; controls the direction and speed.
- Drive Belts: Connect the engine pulley to the transaxle, transferring power.
- Clutch Assembly: Engages or disengages the blades or drive system.
- Wheel Motors or Axles: Transmit power to the wheels for movement.
4. Steering and Suspension
Ensures maneuverability and comfort:
- Steering Linkages: Connect the steering wheel to the front wheels.
- Suspension Springs: Absorb shocks from uneven terrain.
5. Safety and Control Features
Critical for operator safety:
- Seat Switch: Ensures the operator is seated before allowing operation.
- Brake System: Stops the mower safely.
- Control Levers and Pedals: For throttle, blade engagement, and speed control.
