The STIHL RT 4112 S ride-on mower with side discharge is ideal for lawns up to 8000m². The side discharge deck distributes the grass clippings across the lawn during mowing, perfect for less formal lawns where grass collection is not needed. The RT 4112 S comes with a wide (112cm) deck to reduce the time you spend mowing the lawn. As the ride-on mower does not need a grass catcher box it is very compact in size and extremely practical, especially if you want to cut your lawn with speed and efficiency. With the single pedal drive you can simply switch driving directions using the hand lever, which makes it easy to manoeuvre, even in more confined gardens. The low step and ample legroom provide a high degree of driving comfort at all times. The driver's seat can be adjusted tool-free and, like the ergonomically shaped steering wheel and the easily accessible controls, supports relaxed working. The mowing deck blades can be easily engaged and disengaged simply pushing a switch on the control panel. The RT 4112 S comes with a 5 year extended warranty (subject to registration and annual servicing).

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.
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.
Mowing deck with side discharge
Mowing with side discharge allows large lawns to be mown in a short time. This is due to the clippings being ejected directly onto the lawn and not having to empty a grass catcher box.
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.
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.
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.
