A unique feature of the baffle material is that it can be heat formed to match a curved portion of the mower’s discharge opening if required. To shape the baffle, use a heat source such as a heat gun, to heat the area which needs to be formed. After heating the baffle, it can then be formed to the required shape. Following cool down, the baffle will retain its formed shape.

Blade Blocker is designed to operate in conjunction with the discharge deflector shield on the mower.

Blade Blocker is not intended to be used as a mulching plate or in the place of the discharge shield. Its purpose is to temporarily block the discharge opening in order to prevent large volumes of grass clippings from being discharged onto areas where they are not desired.
