Which Way Do Lawn Mower Blades Go On

The direction in which lawn mower blades are installed is crucial for their proper functioning and safety. The blades are designed to rotate in a specific direction, and installing them incorrectly can lead to reduced cutting performance, increased vibration, and even damage to the mower.

Standard Rotation Direction

Most lawn mower blades are designed to rotate in a clockwise direction when viewed from the underside of the mower deck. This means that the curved edge of the blade should be facing the direction of rotation. To ensure correct installation, look for the following indicators:

• A directional arrow or logo on the blade itself, indicating the correct rotation direction.
• A notch or keyway on the blade mounting hole, which corresponds to a matching feature on the mower deck.

If you're still unsure, consult your lawn mower's owner's manual or contact the manufacturer for guidance.

Reversible Blades

Some lawn mower blades are reversible, meaning they can be installed with either edge facing the direction of rotation. These blades typically have a symmetrical design and can be flipped over to extend their lifespan. However, it's essential to follow the manufacturer's instructions for reversible blades, as incorrect installation can still lead to reduced performance and safety issues.
