I came across a story about the use of UTVs on farms in the UK.  This segment includes both farmers and gamekeepers.  According to the story, much like the US market, diesel powered UTVs are often the vehicle of choice for the torque they can deliver.  There are a few brands in the UK market that you do not see as much in the US market including Kioti, Ausa, and JCB, but there are familiar brands as well like John Deere, Kubota, Polaris, Kawasaki and Cub Cadet.  One interesting aspect of the market is that kits to make the UTVs street legal are commonly available options, if not a standard feature already.  Typically the kits cost about 1,000 USD and includes turn signals, rear lights, horn, seat belts, registration holder and tax disc holder.  Learn more:  Farmers Weekly
