Welcome to the September issue of profi. We have a tyres and tracks theme in this issue as we compare eight central tyre inflation systems, get feedback from a farm running a John Deere 8RX while another has opted for a Fendt 939 with the firm’s VarioGrip pressure system. And to round it off we look at what you need to consider when changing tyre sizes. Plus there is all the other great profi content as shown below.
