A handy helper around the garden, the EnergyFlex GT 4030 from AL-KO will provide you with the solution for cable-free grass trimming so you can maintain those areas of the garden that you can't quite get to with your lawn mower.

At the heart of the grass trimmer is a powerful 40 volt 4.0Ah lithium-ion battery which delivers around 60 minutes operating time on a single 90 minute charge. The grass trimmer is fitted with an automatic bump feed nylon line head with a 30cm cutting width. The tilting angle will allow you to trim under bnushes, whilst the pivoting cutting head makes for effortless, speedy edging. 

A replacement line spool is included which can be stored in the receptacle on the machine.


The EnergyFlex series of varied battery-powered machines for cable free and effortless garden enjoyment

The AL-KO EnergyFlex platform comprises three lawn mowers, a lawn scarifier and an array of different hand tools so you have everything you need for your garden.

Suitable for use with all EnergyFlex tools, a battery and charger are supplied with the lawn mowers.The same battery can be used for operation of the bare tools, and an additional 4Ah or 5Ah battery and charger can also be purchased separately.

NB: Battery and charger NOT INCLUDED.
