South Otterington, Northallerton, North Yorkshire, DL7 9HJ, United Kingdom.
We are currently in the process of a major reconstruction of the firm. Two of our team are over or approaching 70 and the younger ones are only interested in Anaerobic Digester and Rotorcrex work. All our farm machinery except a telehandler has now been sold. We reserve the right to decline other services although it's always nice to see visitors. Because of lots of good feedback about useful info on our website we are leaving open several sections just in case there's anything useful. Please also note that two of our phone numbers have changed.
