Product details and specs

Cover a larger lawn the fast, low-effort way with this highly productive 51cm self-propelled petrol lawn mower from Alpina!
With its four cutting-options (bagging; mulching; side-discharge; rear-discharge) and six-stage cutting-height, the AL5 51 SAQ is super-versatile and can be adapted to achieve great results, whatever the grass conditions.
The self-propelled drive on the AL5 51 SAQ eliminates the need to push, which in turn makes it a great choice for anyone whose lawn is on sloping or undulating ground.
A front grass-comb means you’ll achieve a beautifully neat and even finish; while an ergonomically optimised grip works with a two-position quick-adjust handlebar to confer excellent user-comfort.
The AL5 51 SAQ comes equipped with a powerful, large-displacement 166cc STIGA OHV engine, which, thanks to its AutoChoke system, will prove quick and easy to get started.
Built to last, this model is based around a robust steel cutter-deck and benefits from a protective front bumper.
Other key features include a ‘collector full’ indicator that warns when the spacious 60-litre grassbag has reached capacity; ball-bearing wheels that will keep on rolling freely over time; and straightforward single-point cutting-height selection.
