Ken Graham Engineering Ltd is a name that is synonymous with combine parts and accessories for the past five decades. Developing its first concave in 1968, the family-owned business has constantly been looking at ways for farmers to get more from their machines.

According to David Graham from the family engineering company, the high-output concaves have been a huge success all across Europe and in particular France and the UK. David added that the new Maxi Threshing kit concept has already been shortlisted by the International Machinery Manufacturers Association (IMMA), with the firm now down to the last two for an award at this year’s Cereals 2016 event.
