Two Replacement Low Cut Blades for the Robomower RC and RS Series mowers. Depending on when your mower was built, it could have either high cut or low cut blades.
If you are not sure, they can be identified by color. High Cut Blades are black and the Low Cut Blades are silver. High Cut Blades will not fit on a low cut model without alterations to the mower body. Low Cut Blades will work on either type, but will provide a lower cut of .8 to 2.75 inches.
