Featuring a powerful twin-cylinder engine, wide 110cm cutting deck, large grass collector and intuitive single-pedal drive system, it delivers exceptional mowing efficiency, comfort and grass collection performance.

The STIHL RT 5112 Z Petrol Ride-On Lawn Mower is engineered for homeowners and estate owners who need a powerful, comfortable and efficient solution for maintaining large lawn areas. Designed to handle lawns of up to 6,000m², it combines a high-performance engine, wide cutting width and advanced collection system to make large-scale mowing easier and faster.

At the heart of the RT 5112 Z is a robust STIHL EVC 7000 twin-cylinder engine, delivering smooth power and reliable performance for demanding mowing tasks. Its generous 110cm cutting width allows large areas to be covered quickly, reducing mowing time while maintaining an excellent finish.

Comfort is a key feature of the RT 5112 Z. The mower is equipped with a spring-loaded adjustable seat that can be tailored to the operator for a comfortable driving position. Frequently used controls are positioned within easy reach, including the blade clutch, central cutting height adjustment and grass catcher box emptying lever.

The mower features single-pedal drive technology with forward and reverse control conveniently integrated at the steering column. Combined with direct steering, this provides smooth manoeuvrability and effortless operation around obstacles, trees and landscape features.

The innovative Grass Guide System located on both sides of the cutting deck helps direct grass towards the blades, ensuring excellent cutting performance right up to lawn edges. The synchronised blade system delivers an even cut and outstanding grass collection, helping create a neat, professional finish.

A large rear grass catcher box reduces interruptions by allowing longer mowing periods between emptying, while the easy-emptying system improves operator convenience.

Whether maintaining a large domestic lawn, estate grounds or expansive landscaped areas, the STIHL RT 5112 Z offers the performance, comfort and efficiency needed for outstanding mowing results.
