STT-31EFI-SS specifications

Scag Power Equipment is renowned for producing high-quality commercial mowing equipment, and the STT-31EFI-SS stand-on mower is no exception. Designed with professional landscapers in mind, the STT-31EFI-SS offers a perfect blend of power, efficiency, and maneuverability.

One of the standout features of the STT-31EFI-SS is its 31 hp EFI (Electronic Fuel Injection) engine. This powerhouse engine not only delivers impressive power but also enhances fuel efficiency. The EFI technology ensures that the engine operates at optimal performance by automatically adjusting the air-to-fuel ratio under varying conditions. This results in smoother starts, improved throttle response, and reduced emissions, making the mower both environmentally friendly and cost-effective in the long run.

The STT-31EFI-SS features a durable construction built to withstand the rigors of commercial use. Its robust steel frame and heavy-duty components are designed for maximum longevity. Moreover, the mower is equipped with Scag's cutting-edge Hydro-Gear ZT-3400 transmission, which offers exceptional speed and agility. This transmission allows operators to navigate tight spaces with ease and provides a top speed of up to 10.5 mph, making it ideal for large properties or demanding mowing tasks.

Operator comfort is another key aspect of the STT-31EFI-SS. The stand-on design promotes better visibility and quick maneuverability, enabling operators to navigate obstacles with confidence. The padded operator platform and adjustable controls ensure a comfortable experience, even during extended use. Additionally, the mower’s low center of gravity enhances stability on slopes and uneven terrain.

One of the most notable characteristics of the STT-31EFI-SS is its advanced cutting deck. The mower features a 48", 52", or 61" Velocity Plus cutting deck, which is known for delivering a superior cut and impressive grass dispersal. The deck is engineered for optimal airflow, enabling precision mowing while preventing clumping. This technology ensures that grass clippings are evenly distributed, resulting in a healthier lawn appearance.

In conclusion, the Scag STT-31EFI-SS stand-on mower integrates powerful performance, innovative engineering, and comfort. Featuring a reliable EFI engine, robust construction, and exceptional maneuverability, this mower stands out as an excellent choice for professional landscapers seeking efficiency and reliability in their equipment.
