Seems to be due to emissions controls not just in EU but USA and Australasia. Seems that they are heavier though.
I wouldn’t say all the new models are 4 stroke. 4 stroke engines are more efficient due to dedicated intake and exhaust strokes, whereas with 2 strokes, there’s some fuel wasted as when it mixes with the exhaust gases, some leaves with it. Having said that, 2 stroke machines are still absolutely fine, and most machines are still 2 stroke.
I wasn't aware of this. What's the benefit of 4 stroke over 2 stroke then? Is it really seen as an upgrade?
All the new models coming out (various brands) are 4 smoke so I wouldn't buy a 2 smoke now simply because I would like to try a 4 smoke. However, lockdown seems to have caused a hedge cutter shortage, everywhere has most petrol models out of stock.
