UltraCut Mower Decks

Exmark UltraCut 72 Inch Zero-Turn Mower Deck

At Exmark, we're constantly working to perfect our cutting decks because it doesn't matter how much experience you have, if the cut doesn't look good, your business is done. We've left no stone unturned in the quest for the ultimate cut quality. Flow-control baffles accelerate airflow under the deck, so clippings move easily and discharge evenly. We've optimized blade-tip speed to deliver uniform clipping discharge distance and uniformity. Our rear discharge zero-turn mowers offer enhanced clipping control, with the ability to trim on both sides of the deck. And our new UltraCut Flex Wing cutting decks - available in 96-inch and 144-inch on Lazer Z zero-turn mowers – enable you to mow up to 11.5 acres per hour without compromising cut quality or appearance.
