Hi folks, Has anyone tried to hook up an aftermarket seat on a New Holland skid steer? If so, how did you get the pressure safety switch to work? Also, I need to replace the servo control bushings under the seat (the control sticks are sloppy; old bushings are worn out and some are gone). There are 6 of these primary bushings and a number of other bushings as well. My local New Holland (Dallas, Tx) wants $20 each; Messicks wants $17 + $3 shipping each. Anyone have a better source for these kinds of parts? thanks, stephen
