Grinding

The sharpening where blunt and correcting of minor damage to a mower's bottom blade, rotary blade or cylinder. The grinding mechanism will cut away metal to refurbish the blade or cylinder to recreate a sharp edge or to help rebalance a rotary blade. Regrinding might need to be carried out annually, but this will depend on mower usage, effectiveness of routine maintenance and whether any damage has occurred. Regrinding can reduce the life of a blade or cylinder as metal is gradually cut away during the grinding process, yet at the same time extend its life due to refurbishment.
