Mower Blades

Lawn mower blade acts as a fan providing a lift force. Rotary mowers typically have an opening in the side of the housing where the cut grass is expelled. Some have a grass catcher attachment at that point to bag the grass clippings. Rear-catchers is another common design for the same purpose.

Special mulching blades are also available for rotary mowers. The blade is designed to keep the clippings circulating underneath the mower until the clippings are chopped quite small. This avoids the need for bagging the clippings or raking the clippings. Not only does this save labour, as no organics are removed from the lawn, less fertilizer is needed.

On rotary mowers, the blade is seldom sharp enough to actually cut the grass blades. The speed of the blade simply tears the grass resulting in brown tips. By contrast the reel lawn mowers and manual lawn mowers usually work by scissor action on the blades and a cleaner cut is achieved.
