Also a big issue was not that they had to get support or help, but that there are time critical points of the year such as harvest that you need your machine running literally every hour of the day and even though they could easily physically fix or replace a part themselves the machine would lock out until a certified technician came out to plug their laptop in a certify genuine parts are used or fixes have been made.
Then the local certified repairman wasnt able to attend the service call for days and that was just not acceptable when an entire years income would be impacted by the speed they could harvest before potential damages which would affect profit margins.
So its not just the frustration of being locked out but the lack of sufficient manufacturer support.
