I just sold my old,old trencher(tiling drainage machine) that will be 35 years old here in a couple weeks!I have owned it for almost 22 of those years No it is not going into retirement or me,it is actually going to someone else that needs to have it work for them and pay it way still. I think that is quit remarkable in this day and age?Reason being that there actually is and was a limited number of them built and still being built today. Not that many manufacters still today and they only average about 12 machine(one brand) a year today. Just thought i would share.Anyone else sell or use older machines in this age bracket,and trying to make a living with them??????
