The Hustler 607558 OEM Standard Low Lift blades have a subtle curved Discharge Ear at the end minimizing air flow. This reduced suction allows for a cleaner mowing experience, with less dust and debris for a lower liability. Compared to Hi-Flow blades, Hustler Low Flow blades cause less strain on the engine. For dryer sandier conditions and lighter grass types, the Hustler OEM 607558 LO-FLOW Mower Blade is the preferred choice. This Mower Deck Blade was made to Hustler OEM Specifications to fit 48" Dash, Dash XD, Raptor XD, and Surfer Pro.
