About the STIGA TORNADO 9121 W Petrol Garden Tractor

Built to tackle the toughest mowing tasks with ease, the STIGA Tornado 9121 W is a premium-grade petrol garden tractor engineered for durability, performance, and comfort. Whether you’re maintaining a large formal lawn or rough terrain with weeds and thick grass, this heavy-duty ride-on mower delivers exceptional results—quickly, efficiently, and reliably.

Power You Can Rely On

At the heart of the Tornado 9121 W sits a Honda GXV 690 688 cc twin-cylinder engine. Known for its superior build quality and long-lasting performance, this V-Twin, overhead-valve powerplant delivers smooth operation with reduced vibrations, high torque output, and outstanding fuel efficiency.

To further extend engine life and ensure optimum performance, it’s equipped with a two-stage air filter and full-pressure lubrication. And thanks to the extra-large 15-litre fuel tank, you’ll be able to work uninterrupted for longer, with fewer stops to refuel. The tank is also fitted with an external filler cap, making top-ups quick and convenient.

Built for Large and Demanding Lawns

Designed to mow up to 10,000 m², the STIGA Tornado 9121 W is the perfect companion for those needing to manage vast lawns, meadows, or paddocks. The rugged 121 cm cutting deck, fitted with three precision blades, ensures outstanding coverage and efficiency, even in overgrown grass or uneven terrain. The blades engage smoothly via an electromagnetic clutch for a hassle-free start to every mowing session.

This side-discharge model is ideal for quickly dispersing clippings when mowing rougher areas. However, it also includes a mulching plug, allowing you to switch easily to STIGA’s highly effective mulching system on finer, regularly maintained turf.

Advanced Cutting Intelligence

What sets the Tornado 9121 W apart is its intelligent 5.5” widescreen smart display, which continuously relays vital information about your mower’s performance. It monitors engine RPM, battery and oil levels, fuel level, and more. Additionally, the exclusive STIGA Best Cutting Zone feature uses a green-light indicator to show when you’re mowing at peak efficiency—helping you achieve an immaculate finish with every pass, no matter the terrain or grass condition.

Smooth and Controlled Driving

The Tornado 9121 W features a pedal-operated hydrostatic transmission, offering seamless, gear-free control over forward and reverse speeds. This system makes it incredibly easy to navigate around obstacles, adjust speed on the go, and maintain a smooth ride, even on inclines or uneven ground.

For added convenience during longer sessions, it also comes with cruise control, enabling you to lock in your preferred speed and take the strain off your foot and ankle.

This model is built on a heavy-duty cast-iron front axle, offering the kind of robustness required for mowing rough ground and ensuring long-lasting structural integrity.

All-Day Comfort

STIGA hasn’t forgotten about the driver’s comfort. The Tornado 9121 W boasts an ergonomic seat with armrests, a soft-grip raised steering wheel, and a handy cup holder, ensuring every mowing job is completed in comfort. There’s also a storage compartment onboard, perfect for holding your tools, gloves, or even a packed lunch.

LED headlights come as standard, illuminating your path in low-light conditions and extending your working window into the early evening.

Adaptable and Versatile

This machine isn’t just about mowing. The STIGA Tornado 9121 W is a two-in-one garden tractor that can either side-discharge or mulch. Its high-clearance deck and rugged construction also make it compatible with a range of attachments, including a trailer hitch (included as standard). Whether you’re transporting garden waste, spreading mulch, or towing tools, this feature dramatically increases the tractor’s versatility.

Thoughtful Maintenance Features

The Tornado 9121 W includes deck-mounted gauge wheels, helping to prevent scalping when turning or mowing on uneven terrain. A washing link is built into the deck, allowing you to connect a hosepipe directly for quick and easy under-deck cleaning. This helps keep the blades and internal components in tip-top shape, extending the mower’s life and maintaining its cutting quality.

For added peace of mind, it also comes with a battery charger included in the box, making off-season storage and recharging a breeze.

Peace of Mind with STIGA’s Warranty
