Product details and specs

Forget about noisy, environmentally-damaging petrol power and maintain your lawn the quiet, eco-friendly way with the Alpina AL1 3420 Li Kit cordless lawn mower!
Its combination of the latest lithium-ion battery power with a super-efficient brushless motor not only delivers superb performance, but also works to ensure you’ll enjoy lengthy battery run-times and an extended product life. The batteries (x 2) are included in the package and can be used with any of the machines in the Alpina 20V range.
The AL1 3420 Li Kit Li K has a 34cm width-of-cut – that’s small enough to ensure great confined-area manoeuvrability, whilst being large enough to enable you to get the job done fast.
Thanks to its polypropylene deck, this model is comfortably lightweight and will easily withstand any accidental impact it might encounter during its working life.
A roomy, easy-fit catcher - design-optimised for superior collection performance - means time-consuming emptying-stops will be few and far between; while an in-built carry-handle combines with the low-weight build to make lifting and carrying easy for any gardener.
Also featured is centralised cutting-height adjustment – you’ll be able to select your desired working height with one simple movement via a light-touch, spring-loaded lever.
