The last Track Marshall crawled off the production line in the early 1990s, but soggy weather over the past few years means it enjoying a bit of a comeback.
So much so that Lincolnshire dealer Robert H Crawford & Son has sold 15 restored examples of the classic crawler in the past 12 months.
Most have gone to arable producers in more challenging parts of the country that have been forced to leave their heavy, modern machines in the yard.
One was sold to a farmer that had been forced to abandon his rubber-tracked crawler and another went to a livestock farmer for mole draining grassland.

The most popular models are the Perkins-powered 155 and the Ford-engined 120. These have both got hydraulic steering and relatively quiet air-conditioned cabs making them a bit more comfortable than some of the clattery earlier models.
The 155 is more than man capable of handling a five-furrow plough meaning it can cover quite a bit of ground in a day. The only problem is that the metal tracks mean it has to be loaded on a trailer to go down the road.
Robert H Crawford & sons sold the first and last Track Marshalls that came off the production line and when the Gainsborough factory closed it bought the remaining spare parts and drawings.
A restored Track Marshall 155 costs about £12,000 and Crawfords has five in stock at the moment.
