Product details and specs

The fast-working Alpina AL3 45 S is a dedicated mulching machine that eliminates the need to collect and dispose of grass-clippings. Instead, the cut grass is chopped and re-chopped, with the resulting particulates then being evenly spread across the turf where they’ll rot down and become a free organic fertiliser that will noticeably improve the verdancy of your lawn.
Self-propelled via the front wheels, the AL3 45 S offers low-effort operation and will take slopes and areas of rough ground in its stride.
The wheels on the AL3 45 S are ball-bearing mounted for longevity and benefit from a soft tread that works to prevent unsightly turf-marking on delicate surfaces.
A foldable handlebar means you’ll be able to find a space for the mower in the most cluttered of sheds; while five-stage cutting-height adjustment means you’ll be able to achieve the sort of finish you prefer.
This robust, steel-decked machine comes equipped with a fuel-efficient 123cc STIGA OHV engine with Autochoke for no-hassle starting.
A 45cm cutting-width makes the AL3 45 S a good choice for areas up to 1500m2.
