Rather than carrying out a full review of this Hyundai Cordless 42cm, I thought it would be best to tell you the differences between this mower and its smaller brother the Hyundai Cordless 38cm. Why? Well, because they are almost identical apart from a few minor differences that I will detail below.
So to get a full review of this mower see my review of the Hyundai Cordless 38cm here.
Differences between the Hyundai Cordless 42cm Lawn Mower (HYM60LI420) and the Hyundai Cordless 38cm (HYM60LI380)

Deck Size
The deck size on this mower, as the name suggests, is 42cm and on its smaller brother it’s 38cm. So not much in it really, naturally the larger 42cm will get the job done more quickly as it will cut more grass with every pass, but if you have narrow strips of lawn or storage is limited then perhaps the smaller deck size would be a better fit for you.
Hyundai Cordless Lawn Mower (HYM60LI420) = 42cm deck size
Hyundai Cordless Lawn Mower (HYM60LI380) = 38cm deck size
Grass Collection Box
As this mower has a larger deck, there is also a small difference with the size of the grass collection box.
Hyundai Cordless Lawn Mower (HYM60LI420) = 50 litre collection box
Hyundai Cordless Lawn Mower (HYM60LI380) = 45 litre collection box
