High-performance ride-on mower with wide cutting width | STIHL GB
General
The STIHL RT 5112 Z ride-on mower with a powerful 2-cylinder engine, large grass catcher box and wide (110 cm) cutting width, is perfectly designed for large lawns up to 8000m². Enjoy the sprung loaded seat which is adjustable to all heights and master the controls which are close at hand: the forward/reverse drive lever at the steering wheel, the central cutting height adjustment, the blade clutch and the lever for effortless emptying of the grass catcher box. The RT 5112 Z features a very powerful twin cylinder OHV engine for top level performance. In addition the single-pedal operation and direct steering provide a previously unattained level of comfort during driving, manoeuvring and mowing. The Grass Guide System on both sides of the mowing deck catches grass blades at the edge of the deck and guides them towards the cutting blades. The sychronised blade system provides a neat and clean cutting pattern and class leading grass collection. The RT 5112 Z comes with a 5 year extended warranty (subject to registration and annual servicing).
