Hi all. I have been reading through the posts on hydro steer and has anybody come across the hydraulic steering on a Zetor tractor? This has its own belt driven hyd pump, res, ram, etc, but there is no orbital unit on the steering wheel, it uses a conventional steering type arm and some how assists the steering in the dirction required!(dont ask me how it works) As i understand it this would sort out the legal issue of the mechanical link,but dont know how it would perform on the road? I have driven one of these tractors and it did seem a little notchy on the steering, but it was an old tractor! However my thoughts were that if you fitted this system using an airconditioning pump clutch on the hyd pump, and had the ram on quick release couplings, the unit could be simply switched off and removed for road use.
I found this quick link of a system http://www.powersteeringkit.com/zetor.html
