Pros and points of attention
If you want your large lawn finished in fewer passes without fuss, the STIHL RT 4112 SZ is built for you. Its side-discharge deck clears clippings as you go, while the one‑pedal drive keeps control simple and smooth, so you can focus on neat lines and steady pace.
The low step-through and tool-free adjustable seat make getting comfortable quick. Blade engagement is handled from the cockpit, and the grass guide system feeds the full 110 cm width efficiently for a consistent cut.
Where it excels
- Fast maintenance of big private lawns and estates
- Regular mowing where collection isn’t required
- Wide open areas that benefit from side discharge
- Confident manoeuvring around beds and obstacles
Why this model stands out
- 110 cm deck with side discharge to cover ground fast
- 1‑pedal wheel drive for easy speed and direction changes
- Electromagnetic blade clutch (EBC) from the seat
- Comfort seat and low step-through reduce fatigue
Real-world handling
Press the drive pedal to set any speed between standstill and max, then tap the separate brake to stop instantly. The tight 0.7 m turning radius helps when trimming around trees. Turf tyres are gentle on the lawn, and the robust frame keeps the ride solid over uneven ground.

Advice from gardenmachineshop.com
For the cleanest result with side discharge, mow when the grass is dry and overlap each pass slightly to spread clippings evenly.
