I heard agricultural tools have 0 tarrif in nepal .just wondering why everyone is not using .may be they are using I don’t know .no body to work in khet bari these days , even if you get workers they charge high rate .its not profitable.if you have tools you can do everything by yourself.being in nature in your own country is better for your health than living in stress your whole life.you see people working stressful life whole year and visit mountains for hiking once a year to relieve stress.in nepal if you work in agriculture you are in mountains or in nature 24/7 .
