Built to Work


The AirFX™ mower deck attachment is engineered with features that deliver the durability and performance you’ve come to expect from STEINER®. With a deep-deck, bullnose design and patented Air-Gap™ baffle system, the AirFX™ mower deck creates a vacuum that lifts the grass for a superior quality of cut. The extra large discharge allows for ideal airflow and a cleaner deck. A hydraulic lift raises and lowers the deck from the operator’s seat for height of cut adjustments and transport, and an 80-degree hydraulic flip up allows for improved cleaning and maintenance.
