Identifying Thread Direction
To know the thread direction, look closely at the blade. Spot which way the threads go. If threads spiral right, it’s right-hand. If they spiral left, it’s left-hand. Shine a light on the blade. This helps see the threads better. Look at the nut and bolt closely. Hold them in hand. Feel the threads with fingers. This helps identify direction.
Use a wrench to check direction. Turn the wrench slowly. If it tightens clockwise, it’s right-hand. If it tightens counterclockwise, it’s left-hand. A mirror can help see threads better. Place the mirror under the blade. Look at the reflection. Magnifying glass is useful too. It helps see threads clearly. Always handle tools with care.
Replacing Mower Blades
