Vertical harrow blades need to be replaced from time to time.
They wear out or break.
In the case of our vertical harrow, one pair of blades fell off and one pair of blades was worn out.
A pair of blades rotates in the opposite direction to the blade next to it.
Therefore, the teeth of the blades are sharp on both the right and left.
Therefore, before replacing the blade, check the teeth of the blade adjacent to the blade you are replacing and replace it with the blade on the opposite side.
If you are not sure, look at the blade you removed and replace it with it.
