Description
The STIHL RT 6112 ZL Petrol Ride-On Lawn Mower is engineered for homeowners, estate owners and professional landscapers who need maximum productivity when maintaining very large lawns and expansive green spaces. Suitable for areas up to 8,000m², this premium ride-on mower combines a powerful V-Twin engine, advanced mowing technology and outstanding operator comfort to deliver a flawless finish with minimal effort.
At the heart of the RT 6112 ZL is the powerful STIHL EVC 7000 V-Twin petrol engine with a displacement of 635cc. Producing 12.2kW (16.6hp), the twin-cylinder engine delivers smooth, reliable performance with excellent torque, making light work of long grass, uneven terrain and extended mowing sessions. Its refined operation reduces vibration while providing the dependable power expected from a premium STIHL ride-on mower.
The extra-wide 110cm twin-blade cutting deck allows you to mow large areas quickly while maintaining an exceptionally even finish. STIHL’s synchronous mowing deck ensures both blades work together to produce outstanding cutting quality and optimise the flow of grass into the collector. The central cutting height adjustment offers seven positions between 30mm and 110mm, allowing you to tailor the finish to suit different lawn conditions throughout the year. Electromagnetic blade engagement lets you activate or disengage the blades instantly from the driver’s seat with the push of a button.
Grass clippings are efficiently collected in the generous 350-litre rear grass collector, reducing interruptions and allowing you to mow for longer before emptying. The ergonomic sabre-style handle enables the collector to be emptied directly from the driver’s seat with minimal effort. STIHL’s Catching Management System and integrated grass guidance help direct clippings efficiently into the collector while reducing the need for additional trimming around borders and edges. An adjustable fill-level indicator keeps you informed when the collector is ready to be emptied.
The hydrostatic transmission with STIHL’s innovative single-pedal drive system provides smooth, infinitely variable speed control without manual gear changes. A simple hand lever allows you to switch between forward and reverse while the pressure-sensitive drive pedal offers precise speed adjustment. For even greater comfort during longer mowing sessions, the integrated cruise control function allows you to maintain a constant speed across large open areas without continuously pressing the drive pedal.
Operator comfort is at the centre of the RT 6112 ZL’s design. The spring-mounted, height-adjustable seat can be adjusted without tools to suit different users, while the low step-through chassis provides easy access on and off the machine. A high-contrast LCD display clearly presents important operating information including running hours, battery status, oil pressure and grass collector status, ensuring you remain fully informed throughout every mowing session.
The robust steel frame provides excellent stability and durability while also allowing compatible accessories, such as a snow plough, to be fitted for year-round versatility. Turf-friendly tyres help protect delicate lawns by minimising marking, while the compact steering geometry and tight turning radius make manoeuvring around trees, flower beds and landscaped gardens surprisingly easy despite the mower’s large cutting width. A tow hitch further extends the machine’s versatility for transporting compatible trailers and garden equipment.
Built to STIHL’s renowned engineering standards, the RT 6112 ZL is designed for years of dependable service with straightforward maintenance and premium-quality components throughout. Its combination of exceptional cutting performance, advanced operator features and powerful engine makes it one of the most capable collecting ride-on mowers in the STIHL range.
The STIHL RT 6112 ZL Petrol Ride-On Lawn Mower is the perfect choice for anyone looking for a premium garden tractor with a powerful V-Twin engine, hydrostatic transmission, cruise control, a 110cm cutting deck and a large 350-litre grass collector. Whether you’re maintaining extensive domestic gardens, country estates or commercial green spaces, the STIHL RT 6112 ZL delivers outstanding productivity, exceptional comfort and the professional finish expected from STIHL.
