Combining powerful engine performance, advanced comfort features and outstanding cutting quality, it makes maintaining expansive lawns faster, easier and more enjoyable.

Powered by the robust STIHL EVC 7000 twin-cylinder engine, the RT 6112 ZL delivers smooth power and excellent reliability for demanding mowing tasks.

The high-contrast LCD display provides clear information on mower functions, operating hours, battery status, oil pressure and collector box status, ensuring that important information is always visible, even in bright sunlight.
