The annual Cheffins Harrogate Vintage Sale at Great Yorkshire Showground

The tractors offered date from the early 1930s through to classic models from the 1980s and 1990s, which is a section of the market now making some of the highest prices at auction.

One of the highlights of the tractors on offer is a 1991 Jeweltrac Logtrac tractor from Ayr, Scotland. With only 1,073 hours on the clock, the Logtrac is expected to make around £20,000.

Similarly, a 1967 Foden Ballast Tractor has been meticulously restored by its Harrogate-based current owner and is set to make between £10,000 and £15,000.

There are also three Ford classic tractors dating from 1988 – 1990 which are offered by a single owner based in Lancashire. One of these is an excellent example of Ford models from the early 1990s and has spent the majority of its working life at Manchester Airport.

The Fords are expected to generate between £10,000 and £15,000 apiece.

Outside of the tractor section, there is a 1980 Mercedes-Benz Unimog utility vehicle which is available from between £10,500 and £12,500 having been fully restored.

In addition there is a custom-built roadman’s utility carriage which was constructed to be pulled behind a steam roller, two Land Rovers, a 1984 Rolls Royce Silver Spirit and two classic commercial vehicles.

Bill King, chairman of Cheffins said: “We expect buyers to be particularly interested in the classic tractors from the 1970s, 1980s and 1990s which are now making some of the highest prices at auction. The incredibly rare 1991 Jeweltrac Logtrac is set to create a stir as is the 1976 Roadless tractor, which is believed to be one of only 32 of these models ever built. We have also seen a number of Ford collectors looking to diversify their collections so we would expect the classic Ford trio from the same owner sell well.”

Hosted by East Anglian-based auctioneers, Cheffins, at the Great Yorkshire Showground on August 18, the sale is set to draw crowds from across the UK and Europe.
