About the STIHL RT 6112 ZL Petrol Ride-on Mower

STIHL RT 6112 ZL: Luxury Ride On Mower for Large Lawns

When you own a large lawn and have got high standards, the STIHL RT 6112 ZL is a super choice of ride on mower. Designed to handle lawns up to 8,000 m², this powerful petrol machine represents the best of STIHL ride on mowers, combining leading-edge technology with exceptional operator comfort to give you an A1 lawnmowing experience.

An Engine You Can Depend On

This advanced STIHL lawn tractor is equipped with a robust EVC 7000 twin-cylinder engine, producing an impressive 12.2 kW (16.6 hp) from a displacement of 635 cm³. With this kind of strength, it can tackle large areas of grass with ease, while a spacious nine-litre tank ensures fewer interruptions for refuelling. Even at full power, the RT6112 ZL maintains a remarkably low sound pressure level of just 86 dB(A). This careful balance of power and quiet operation makes it the ideal riding mower for suburban gardens and other noise-sensitive areas.

Outstanding Cutting Performance

At this STIHL garden tractor’s cutting edge is a wide 110 cm (43-inch) deck. The twin blades are precisely offset and rotate in synchronisation, delivering a consistently neat, uniform cut. From shorter, ornamental lawns to areas with thicker growth, the centrally adjustable cutting height—ranging from 30 mm to 110 mm—ensures you have complete control over the finish. This is a mower that adapts to your lawn, rather than the other way around.

Smart Grass Collection and Mulching Option

This STIHL lawn mower ride on comes with a generously sized 350-litre catcher box, emptied easily using a curved sabre handle from the driver’s seat. Its dumper-style shape guarantees extremely efficient emptying, while a handy fill-level indicator ensures you know exactly when it needs to be done. STIHL’s integrated grass catching management system channels the grass from the sides of the mower towards the deck for tidier edge cutting, so there’s less need to finish the job by hand.

For gardeners who prefer to deal with clippings the natural way, the RT6112ZL STIHL sit on lawn mower can be fitted with the STIHL AMK 127 Mulching Kit—available to buy as an optional extra. This clever accessory finely chops clippings and redistributes them onto the turf, where they act as a nutrient-rich mulch.

Precision Handling with Effortless Control

The STIHL RT 6112 ZL Petrol Ride-On Mower is designed to make mowing straightforward. A single-pedal hydrostatic drive delivers smooth, precise speed changes in both forward and reverse, so there’s no need for awkward manual gear shifts. Manoeuvring around trees, borders and flower beds feels intuitive, with excellent responsiveness under your foot. The inclusion of a separate brake pedal ensures instant stopping power whenever you need it. For long straight sections of lawn, you can activate this STIHL sit on lawn mower’s cruise control at the push of a button, removing the need to hold down the pedal continuously.

Exciting Technology at Your Fingertips

Modern technology runs right through the RT6112ZL’s design. A bright LCD display provides real-time updates on essential information such as working hours, oil pressure and grass box capacity. Clear and easy to read, even in bright sunlight, it keeps you fully informed and firmly in control. Protection for the mowing deck comes from an electromagnetic blade clutch, which allows you to switch the blades on or off from the driver’s seat, ideal when crossing uneven terrain or gravel paths.

Comfort and Build Quality Combined

This STIHL lawn mower tractor has to be one of the most comfortable riding mowers to operate. Mounting the machine is simple thanks to its low step-on design. Once aboard, the spring-mounted seat lets you adopt a healthy, comfortable posture—there’s no need for tools, it’s simple to adjust manually. Specialist turf tyres protect delicate lawns, leaving minimal marks behind, while an exceptionally strong frame provides both stability and resilience, ensuring years of dependable service and consistently impressive results.

Optional Extras for Even Greater Versatility

To further extend the riding mower’s capabilities, STIHL offers a number of compatible accessories. Alongside the mulching kit, you can equip this mower with a garden roller, deflector or snow clearing set, along with a protective cover. This versatility makes the RT6112ZL more than just a mower—it becomes a proper year-round partner in garden care.
