997 Z-Trak Mower

Whether mowing with a side-discharge deck, a rear-discharge deck, or with a mulching deck, the 997 excels in the toughest mowing conditions. In short, the heavy-duty, large-capacity 997 gives you front-mower like power in a zero-turn mower while providing the productivity and dependability you value.

Power is in ample supply, thanks to a 31-hp Yanmar diesel engine. This engine provides more displacement and peak torque than most competitive mowers, which allows you to maximize acres mowed per hour. Shaft-driven mower decks are available in 60- or 72-in. 7-Iron II™ side-discharge decks or a 60-in. reardischarge deck.
