Operator manual for M205 says machine is compatible with Trimble Autopilot Hydraulic integrated steering.  The machine in question is equipped with the steering valve.  TopCon does have a kit for M1 models but not specifically the M205.  Anyone out there able to tell me if the cab's are similar between the M1 and the M205?  Any one gone a step further and doctored a Topcon system to work on a MacDon M205 with hydraulics instead of electric steer wheel?
