Blade mounting and drive system
Blade
Deck housing
There are three basic structural members to a rotary cutting unit.
Cutter Deck Housing
The deck housing supports the blade hubs with their drive mechanism and is shaped to carry the cut grass clippings away from the deck in an effective manner.
Blade mounting and drive system
The blade is normally driven directly by the engine crankshaft, a hydraulic motor or through a belt pulley system to each blade hub.
The blade
The blade has a sharpened cutting edge at each end with a curved up sail area to create an air flow. This air flow will whip the grass blades exposing them to the blade cutting edge. The air flow also assists in carrying the cut grass blades out the discharge.
