I bought this old 1390 because farm works are getting too expensive. We breed horses and 600 hay bales are needed every year. So plowing and seeding are easy for my 16 year old son and any old 50hp tractor will do.
It took us a few hours in internet to choose this machine. Here in Portugal this kind of tractor ( 30 years old or so) still coast about $2500 or more. I expect to work with it for many more years ( as long as we breed horses ) and hope it will not fail.
