I bought a 250mm Airecut blade for my Hitachi 21cc brushcutter about 6 months ago and it's great! Cuts through small saplings, blackberry, gorse and fennell easily and on grass is faster than a mower or slasher and also much easier on me. It doesn't seem to matter whether the grass is wet or how long it is. As it is so easy I'm thinking of getting the 300mm or 350mm to go even faster.
