If the blade bolt comes with a washer, its concave side will be facing the blade.
Does the position of mower blades matter?
What is the ideal three blade mower orientation? It actually doesn’t matter. When a mowing deck has three blades it does not need timing. This is because there is no chance of the blades hitting each other.
How should mower blades be oriented?
Most lawn mower blades rotate in a clockwise direction (counter-clockwise when viewed from below), and as such have the cutting edge on the right side. If you are unsure of how your mower rotates, check the position of the discharge chute; if it is on the right side angled back, the blade turns clockwise.

If it has the word “Bottom,” or a model number printed on it, that side of the blade faces the ground when the mower is upright. If there are no markings, check the blade’s bevel. The beveled portion must face away from the ground when installed. The bend in mulching blades also must point away from the ground.
What is mower blade offset?
In the most basic of definitions, blade offset is the distance from the tip of the blade to the center of its shaft.
Why do my lawnmower blades hit each other?
The belts are not cog belts, and there will be slippage, so you cannot count on them maintaining their orientation as you mow. They are offset (middle one forward) so they overlap as you drive forward, but each one turns in a circle OUTSIDE the other blades’ circle.
Do lawn mower blades overlap?
