The STIGA Tornado 5108 W is a powerful side-discharge garden tractor built for homeowners and professional users who need strong performance across larger lawn areas. Combining a 108cm cutting deck, twin-cylinder petrol engine and smooth hydrostatic drive, it is designed to make demanding mowing jobs faster and more comfortable.
At its core is a 586cc STIGA twin-cylinder petrol engine, providing the power required for regular mowing and heavier garden work. The tractor’s hydrostatic transmission allows the operator to control ground speed smoothly using the foot pedal, without the need for conventional gear changes.
Wide 108cm Cutting Deck
The 108cm cutting width allows a substantial area of lawn to be covered with each pass, helping reduce the overall time spent mowing.
Seven cutting-height positions provide adjustment between 25mm and 80mm, making it possible to select an appropriate height for different lawn conditions.
The side-discharge deck is particularly useful when dealing with longer grass, distributing cut material across the lawn rather than requiring repeated stops to empty a collection box.
Mulching Function
When the lawn is maintained regularly, the supplied mulching kit allows the grass clippings to be finely processed and returned to the turf.
This reduces the need for collecting and disposing of grass and allows the cut material to decompose naturally, returning organic matter to the lawn.
Twin-Cylinder Performance
The 586cc twin-cylinder STIGA engine is designed for users looking for additional power and smooth performance. STIGA’s twin-cylinder configuration makes the Tornado 5108 W well suited to larger mowing jobs and regular heavy-duty garden use.
STIGA also provides a 3-year warranty on twin-cylinder engines when the applicable servicing requirements are met through authorised STIGA dealers.
Comfortable & Practical Operation
The Tornado 5108 W features an adjustable STIGA seat and raised steering wheel to provide a comfortable driving position during longer mowing sessions.
Integrated LED headlights provide additional visibility when working in fading daylight or shaded areas.
A supplied tow hitch allows compatible garden accessories such as trailers and aerators to be attached, adding versatility beyond standard mowing.
