Alpina AT3 98 A Riding-on mower

Alpina AT3 98 A riding-on mower with side discharge.

Alpina AT3 98 A riding-on mowers with side discharge are ideal for mowing in large spaces without too many obstacles. The side discharge is really helpful in case of tall grass and makes work faster.

Thanks to the 98 cm 2-blade cutting deck, the performance is excellent, suitable for large surfaces! Equipped with large pneumatic wheels with excellent steering radius that allow very easy handling in the smallest spaces.

This model features a new design and a powerful, reliable engine. The 352 cc Alpina ST 350 engine develops 8.8 HP at 2800 rpm.

Cutting systems

1- SIDE DISCHARGE (standard supplied): the most traditional cutting system which allows cutting the grass and leaving it on the lawn. This system is recommended for mowing large-sized areas and for those who have to cut over-grown grass, for which the mulching or the grass collector system are no longer efficient.

2- MULCHING (optional): this system allows shredding the grass really finely, so that it looks as if it has been collected. This eliminates the problem of its disposal (reducing any effort and shortening the time-saving). Moreover, grass clippings will break down into nutrients and water for the lawn (grass is 80% water) and will thus ensure a perfectly balanced biological cycle. However, please remember that, to ensure the greatest mulching results, the lawn must be watered and the grass needs to be cut often. The conversion from one system to another is easy.
