Common replacement parts for Western Auto front-engine lawn tractors
- Brake interlock switch. The brake interlock switch detects whether you have the brake pedal fully pushed down. The parking brake holds the brake pedal in the fully depressed position so the brake interlock switch also recognizes whether you have the parking brake set. The brake interlock switch won't allow you to start the tractor without the parking brake set or the brake pedal fully depressed.
- Blade clutch cable. The blade clutch cable connects the blade clutch lever to the blade belt idler arm on the mower deck. When you shift the clutch lever to engage the cutting blades, the cable pulls the idler arm, which then tightens the blade belt and spins the cutting blades. The blade clutch cable releases blade belt tension so the blades don't spin when you shift the blade clutch lever to disengage the cutting blades.
- Carburetor rebuild kit. The carburetor rebuild kit includes gaskets, seals, a hinge pin and other components to refurbish the carburetor.
- Fuel filter. A fuel filter is a filter in the fuel line that screens out dirt and rust particles from the fuel. The fuel filter paper is usually integrated into a cartridge. Fuel filters used with in most internal combustion engines.
Troubleshooting your Western Auto front-engine lawn tractor when its deck vibrates
If the mower vibrates when you engage the cutting blades, there might be a problem with the blade drive system. Deck vibration can be caused by an unbalanced blade, worn pulley or mandrel, bad blade belt or debris caught inside a pulley. Loose nuts or bolts on the pulleys, mandrels or blades can also cause vibration. Remove the mower deck and re-tighten all fasteners. Check for wear on pulleys, mandrels and blades. Replace any worn or damaged components.
