Probably worn cab mounts or could be caused from rear tires. Have you checked rear tire air pressures?

Hello Peter, welcome to YT. My guess is that it has a Powershift transmission and you are in the highest gear. I will second what Jim has responded. If it has a 16 speed Quadrange you are reporting that you are experiencing this is D range, speed 3 or road gear with low/hi in the low position.

Thanks for the help I was hoping that would be the answer and not a gearbox issue got it on a good road tonight after letting down the tyres to 15 and its alot better cab bushes would sort it altogether. There's a rcl codes on the dash and a lighting sign on the dash to sort now
