The robust, 2mm-thick blades on this cartridge perform deep-level scarifying, so it’s a great choice for lawns in particularly bad condition.
This cartridge had a new design for 2024 - the blades now have a series of additional holes, and feature an additional three rods to hold them in place. This ensures that there is no movement of the blades and they remain perfectly fixed.
The blades are fashioned from hardened steel.
