With the STIHL RT 5112 Z, a precise cutting pattern and high level of driving comfort are guaranteed. Lawn mowing is time-saving and effortless. Thanks to its cutting width of 110 cm, you can work efficiently with this ride-on mower and while benefiting from the integrated synchronous mowing deck. Synchronisation of its blades ensures a consistently high cutting quality and optimal transport of the grass to the extra-large 350-litre grass catcher box. The grass catcher box of the lawn tractor can be conveniently emptied from the driver’s seat. The driver’s seat can be adjusted without tools so that you can work in an ergonomically favourable manner. From here, you can effortlessly change directions via the single-pedal self propulsion in order to manoeuvre more easily and faster in narrow passages. You can also achieve particularly convincing results in a short time thanks to the simple cutting height adjustment and the electromagnetic blade clutch for activating and deactivating the mowing deck. With the aid of the catching management system, the grass can be optimally gathered across the entire cutting width and guided towards the blades for cutting.
The large turf tyres of the STIHL ride-on mower protect the lawn. Thanks to their rounded tyre shoulders, they reduce the formation of driving tracks.
The integral trailer hitch enables easy mounting of attachments such as the convenient PICK UP 300 tilting trailer, which can also be used as a wheel barrow.
Thanks to the high-contrast LCD display, you have all the important ride-on mower functions under control, including operating hours, battery voltage, grass catcher box readiness, grass catcher box filling level and emptying time, fuel tank filling level, oil pressure monitoring, mowing deck activation.
Central cutting height adjustment
The lever for central adjustment is located directly next to the driver’s seat. It enables individual adjustment of the cutting height in up to eight steps.
The robust frame construction ensures the necessary stability and driving comfort. The compact design of the STIHL ride-on mower also impresses when working with attachments such as the snow clearing set, for example.
Synchronous mowing deck
The synchronous mowing deck provides for consistent cutting quality and optimum grass transport to the ejection chute. This is made possible by the synchronised rotation of the blades, which are offset by 90°.
Spring-loaded and adjustable seat
The perfect seat position can be set without the use of tools. This permits individual adjustment of the driver’s seat to almost any body size.
The low step on the STIHL ride-on mowers provides ample legroom and enables comfortable mounting and dismounting.
Catching management system
The catching management system on both sides of the mowing deck provides for optimal gathering of the grass blades across the entire working width. It guides the grass to the mowing blades.
Grass catcher box with bow handle
The plastic grass catcher box can be emptied effortlessly from the driver’s seat by means of a bow handle. The “dumper” design ensures optimum filling and residual-free emptying of the grass catcher box. Cleaning can also be performed with ease.
With the STIHL single-pedal self-propulsion, the direction of travel can be conveniently switched between forward and reverse gear using a hand lever to facilitate quick manoeuvring. The pressure-sensitive pedal permits fine control of the speed between top speed and standstill. The separate brake pedal ensures immediate stopping.
Electromagnetic blade clutch (EBC)
The clutch system for mowing deck activation facilitates engagement and disengagement of the blades. It can be conveniently operated from the control panel.
With the mulch insert, the STIHL ride-on mowers can be converted into mulching mowers. For this purpose, the grass catcher box is simply removed and the mulch insert pushed into the grass catcher tunnel. This allows the grass to be shredded into fine particles inside the closed housing before they fall back into the turf, returning vital nutrients and moisture to the soil. Through this natural form of fertilising, disposal of the clippings is dispensed with.
