I would also take a look at the Geringhoff much more proven and lots of them around so you can visit with the farmers that have been running them for a few years now. It has a cutting system that isn't so speed sensitive like the lawn mower headers that are out there drago being one and cresonni and harvestec being the others. Also take a long look at the workmanship on these heads and you will see the geringhoff to be the best built one out there, with lots of satisfied customers out there to back it up.
