Scag Liberty Z 107cm Zero-Turn Mower 22 HP Kohler
The Scag Liberty Z 42 is a zero-turn riding mower built for residential lawn care, powered by a 22 HP Kohler 7000 Series engine and a Hydro-Gear ZT-2800 transaxle. Its 107 cm fabricated Hero cutter deck uses sealed ball bearings and blade-drive spindles, giving you a durable cutting platform that stays consistent season after season.
With forward speeds up to 11.3 km/h and reverse up to 8 km/h, the Liberty Z covers larger residential lawns efficiently while its zero-turn steering lets you maneuver around beds, trees and tight corners. The tubular-steel mainframe, 13.2 L fuel capacity and included armrests support regular mowing sessions, and the mower is backed by a 5-year or 750-hour residential warranty.
