We have a 650H dozer and are interested in trying blade control/gps on a machine. Can you put integrated machine control on a machine this age? We talked about trading up for something newer but our 650H only has like 3K hours on it and we have owned it since almost new (Demo machine). I have heard that our H has more power than the J's do not know if that is true or not since I have not ran a 650J.
You can. I'd get a few quotes on price before you get too far. The 650H still use a manual linkage to control the hydraulics. Someone like Trimble/Topcon/Leica could put a parrallel valve on the machine that is eclectro-hydraulic, but those systems get up there in cost.
