Hayter produce a range of battery machines from Hawk mowers with a lightweight ABS Polymer deck to the heavier Harrier range all of which will give that classic striped effect for your lawn. The machines are powered by 60V Lithium-Ion batteries of various sizes from 135Wh upto 540Wh. The Wh (Watt Hours) shows how much power a battery stores, the higher the Wh the more power stored, this is like knowing “how much fuel is in the tank”. All the batteries are interchangeable across the Hayter battery range and will also fit the Toro Flex Force handheld machines which include a strimmer, hedge trimmer, chainsaw and blower. One battery and charger can power all your garden tools.
