With a 61-inch cut width and a powerful 29 HP Kawasaki engine, this mower offers exceptional cutting capabilities, enabling users to tackle large lawns and challenging terrain with ease.

One of the standout features of the STT61V-29KB-DF is its patented Velocity Plus cutting deck. This innovative design enhances grass flow, resulting in a clean and precise cut.

Another notable technology in the STT61V-29KB-DF is its hydrostatic transmission, which provides seamless speed and direction changes without the need for gear shifting. This feature allows for superior control and responsiveness, especially when navigating around obstacles or tight spaces.

Safety features are also prioritized in the design of this mower. It includes an automatic safety shut-off system that stops the blades when the operator leaves the seat, while the robust structure provides stability on slopes and uneven terrain.
