The large turf tyres of the STIHL ride-on mower help to protect the lawn. Thanks to their rounded tyre design, 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 can easily see all the important ride-on mower functions; including operating hours, battery voltage, grass catcher box filling level and emptying time, fuel tank filling level, oil pressure monitoring, mowing deck activation.
Central cutting height adjustment
The lever to adjust the deck cutting height 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 gives the mower a high level of stability and driving comfort. The STIHL ride-on mowers compact design is great for using attachments such as the AGW 098 garden roller or PICK 300 tilting trailer.
Synchronous mowing deck
The synchronous mowing deck provides consistent cutting quality and optimum grass flow through to the catcher box. This is made possible by the synchronised rotation of the blades, which are offset by 90°.
Spring-loaded and adjustable seat
The most comfortable seat position can be set without the use of tools. This allows 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 allows for comfortable access to the seat.
Catching management system
The catching system guides the grass blades across the entire working width of the mowing deck. It helps to guide the grass towards the mowing blades for a more efficient cut.
Grass catcher box with bow handle
The polymer grass catcher box can be emptied effortlessly from the drivers seat simply using the curved shaped handle. The "dumper" design ensures optimum filling and residual-free emptying of the grass catcher box. Cleaning the catcher box is also easy.
Single pedal drive
With the STIHL single pedal drive, the direction of travel can be conveniently switched between forward and reverse gear using a hand lever for quick manoeuvring. The pressure-sensitive pedal allows for precise control of the speed between top speed and standstill. The separate brake pedal ensures immediate stopping.
Electromagnetic blade clutch (EBC)
The mowing deck can be easily engaged and disengaged by a switch situated on the control panel
With the mulch insert, the STIHL ride-on mowers can be converted into mulching mowers. The grass catcher box is simply removed and the mulch insert pushed into the grass catcher chute. 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, there is no need to dispose of the grass.
