Try pulling out the choke and adjusting the throttle. * The carburetor may not be receiving fuel, possibly due to an empty fuel tank. Refill the fuel tank. * The spark plug could be defective or dirty. Check the spark plug, referring to the engine manual for guidance. * There might be no ignition spark.

    • D
      Deborah TuckerAug 19, 2025

To resolve this, sit on the driver’s seat, fully depress the brake pedal or apply the parking brake, and switch off the cutter deck. * The battery might not be connected correctly. Ensure the red cable is connected to the (+) battery terminal and the black cable to the (–) terminal. * The battery could be discharged or low. In this case, charge the battery. * A fuse may have tripped. Replace the fuse. If it blows repeatedly, there may be a short-circuit. * There might be a loose earth cable between the engine and frame. Connect the earth cable to fix this.
