OK, after looking at upgrading to a new S185 with joystick control, I have decided to keep my 2002 753G, as the new ones I tested were almost deafening for cab noise as compared to my 753. Anyway, my question. My machine does not have the any electrical connection on the loader arm, only the front aux. hydraulics. It does have all of the buttons and knobs on the steering levers, but I am not sure, at this point, what is fuctional. If I purchase a Bobcat snowblower, what is required to make everything work. Thanks in advance.
