Hi my old manireach 2600 has four wheel steering but I parked it up in the barn after feeding the cattle the next day I backed it out the cattle barn after starting it up,and the back wheels are not in the right position e.g. When the front wheels are straight normally back ones the same. But now when the front wheels are straight the back ones are at 11oclock so when I drive it the back is always on the crab. I know some models had a dash board switch to do different steering modes but this manitou is not like this. There is red leaver by the drivers right hand knee, on the side pannel Iv turned it and moved steering in full lock both ways. It's as if some thing needs re setting so all 4 wheels point and turn at the same time. Regards ray, any suggestions would be a great help. I think it's some sensor or hydraulic valve or some thing. Thanks again.
