Expansive areas of overgrown, out-of-control grass can be quickly and efficiently tamed with this 108cm side-discharge garden tractor from Alpina!
It might be a substantial machine, but the Alpina AT3 108 HA is nevertheless highly maneuverable, with its infinitely adjustable hydrostatic transmission enabling precision ground-speed control and ensuring you’ll find it much easier to work around obstacles than you would with a stop-start manually-driven model.
The AT3 108 HA isn’t just for long growth - with the purchase and fitting of the optional mulch-plug, you’ll be able to achieve a beautifully neat finish on a well-maintained formal lawn.
Alpina’s provision of seven preset heights-of-cut means you’ll be able to manage a diverse range of conditions; while large wheels provide high-grip traction in damp weather and on muddy surfaces.
Thanks to an electromagnetic PTO clutch, engaging the blades on the AT3 108 HA couldn’t be easier.
Power comes from a large-displacement 452cc STIGA ST500 single-cylinder engine with fuel-saving, emission-limiting and noise-reducing overhead-valve (OHV) technology.
Also featured is a front bumper for peace of mind in terms of impact resistance; and twin headlights that make it possible to continue working long into the evening if necessary.
