The GRAECUS ZTR158 PRO is a commercial-grade professional zero-turn riding lawn mower, designed for fast, comfortable, and efficient mowing of large green areas. It is suitable for professional landscaping contractors, municipalities, hotels, large estates, sports facilities, parks, and demanding users who require high productivity and a clean, precise cutting result.
The zero-turn radius allows the machine to turn virtually on the spot, providing exceptional maneuverability around trees, flower beds, obstacles, and narrow spaces. This reduces unnecessary maneuvers, uncut areas, and overall working time.
The Zonsen XP1000 EFI V-Twin 35 hp engine, with a displacement of 1000 cc, features Electronic Fuel Injection (EFI). The EFI system provides smooth operation, immediate throttle response, strong torque, and more efficient combustion compared to conventional carbureted engines. During demanding mowing operations, particularly in thick or tall grass, it helps the engine maintain consistent performance and improved response to changing loads.
The Hydro-Gear USA ZT-3800 hydrostatic transmission provides smooth, efficient, and reliable movement, with precise control and high durability for professional applications. The two independent steering levers allow accurate maneuvering and complete control over the machine’s movement.
The cutting system features a heavy-duty fabricated deck with a cutting width of 1573 mm / 158 cm, 3 cutting blades, and an adjustable cutting height from 25.4 to 127 mm. The assisted deck-lift system allows easy height adjustment using a locking pin, enabling the machine to adapt to different types of lawns and working conditions.
The blade arrangement has been designed with overlapping cutting paths to minimize uncut strips and achieve a more uniform finish. Depending on the application, suitable blade types can be used for different lawn conditions.
The GRAECUS ZTR158 PRO is equipped with a CRP USA drive belt, an OGURA Japan electromagnetic blade clutch, and a Hydro-Gear USA hydrostatic transmission. The CRP belt provides reliable and quiet power transmission, while its V-shaped profile increases contact with the pulley for improved grip and more consistent operation. The OGURA electromagnetic clutch ensures immediate and precise blade engagement, consistent cutting performance, and extended cutting system service life.
The operator’s station is designed for comfortable operation over extended working periods, featuring a high-back seat, ergonomic adjustable steering levers, and a spacious operating area. The foldable ROPS (Roll-Over Protective Structure) provides additional operator protection and can be folded down when passing beneath low branches or through areas with limited overhead clearance.
The removable floor panel provides quick access to the cutting deck for cleaning and maintenance. The lawn-friendly Turf tires help protect grass surfaces, while the robust frame, large wheels, and heavy-duty construction ensure durability, stability, and smoother movement across demanding terrain.
The frame construction incorporates robotic welding for high precision and consistent manufacturing quality, as well as electrophoretic coating and powder coating for improved resistance to corrosion and weather conditions. The design has undergone salt spray testing and QUV accelerated aging testing to ensure greater durability in outdoor applications.
With a 60 L fuel tank, electric starter, LED lights, hour meter, rear attachment point, heavy-duty rubber discharge chute, and a mulching kit included in this configuration, the GRAECUS ZTR158 is a complete commercial solution for professional maintenance of large green areas.
It is supplied with CE / EPA / EURO 5 certifications and compliance documentation for professional applications.
