Z Master Professional 5000 Series mowers offer rear discharge decks for increased productivity in taller grass. These EFI models also use up to 25% less fuel than equivalent non-EFI mowers. The rear discharge design allows operators to trim on either side of the deck — no need to change direction to avoid discharging debris on roadways, sidewalks or flowerbeds. Clippings are dropped within the path of the mower, saving time and cleanup.
