The Kubota Z251KH is a professional-grade zero-turn mower introduced in 2019, designed for high-efficiency lawn maintenance. It combines a powerful gasoline engine with hydrostatic drive technology to offer precise maneuverability in residential and commercial landscaping applications.
Engine and Performance
The machine is powered by a Kohler ZT740 air-cooled, vertical-shaft V-Twin gasoline engine. With a displacement of 747 cc (45.6 ci), it delivers 25 horsepower (18.6 kW). The engine features a two-cylinder design and is paired with an electric starter, ensuring consistent performance for intensive mowing tasks.

Equipped with a 54-inch mower deck, this model is designed for high-capacity cutting. The independent mid-PTO is managed via an electric clutch, allowing the operator to engage or disengage the deck efficiently. The system is designed to support the demands of high-productivity landscape management.

The mower has a wheelbase of 45.5 inches (115 cm) and a total weight of 771 lbs (349 kg). It features a two-post fixed ROPS (Roll-Over Protective Structure) to enhance operator safety. The machine is fitted with lawn/turf tires—11x4-5 at the front and 22x10-14 at the rear—designed to provide stability while minimizing surface damage.
