Description

This 2019 Kubota Z421KW-54 is a clean, low-hour commercial-grade zero-turn mower built for serious property maintenance and turf care. It pairs Kubota’s factory-matched RCK54-400Z 54-inch fabricated PRO deck with a proven 24 HP Kawasaki V-Twin engine — a reliable combination that delivers both excellent cut quality and long-term durability.

The 2-HST hydrostatic transmission with gear final drive provides smooth, responsive zero-turn handling and strong ground speed (up to 10 mph forward). Whether you’re maintaining fine turf or tackling rougher areas, the 54-inch commercial deck with three blades produces a clean, consistent finish while the adjustable cutting height (1.5"–5.0") gives you flexibility across different conditions.

Operator comfort is well addressed with a suspension seat that reduces fatigue on longer days, and the foldable ROPS allows for easier storage or transport when needed. With a 6.8-gallon fuel tank, this unit offers extended run time between refills.

Why This One Stands Out

At only 228 hours, this 2019 Z421KW is barely broken in for a commercial-grade machine. Most major components — belts, spindles, and hydrostatic transmissions — are still in their prime service life. The low hours, combined with the durable Kawasaki engine and Kubota’s proven deck design, make this a strong choice for anyone looking for a reliable, high-production zero-turn without paying new-equipment prices.

Zero-turn steering and the intuitive two-hand-lever controls make it easy for newer operators to learn quickly while still delivering the performance and efficiency that experienced crews expect.
