It's its season and I just wondered why this mower isn't so popular in North America. Why? Its price too is great (a month ago, I bought a 5' drum mower and paid only about US$900. I believe 4' would cost cheaper) Comparing its performance&price to other mowers, I think the drum mowers should have been popular all over the world. Are you sure that the farmers' needs direct the market or is it the sellers' need that controls the market? So, we can say farmers' need for drum mower is much less than the sellers' need, hence drum mower is less popular there?
