Tractors stretched for almost two miles, at times from skyline to skyline, across the Cornish countryside on Sunday as part of an annual event to raise money for an armed forces charity.
Organisers of the Lanivery Tractor Road Run expect the event, which at times was carried out in pouring rain and thunder storms, raised more than £500 for Help for Heroes.
Some 36 tractors, from vintage Massey Fergusons and Fordsons to more modern John Deeres, took part in the event which saw the tractors wind their way through 45 miles of Cornish lanes.
The highlight of the journey included a drive from Par to Fowey along private land belonging to china clay company Imerys, that included a stretch through underground tunnels.
The event, which started from Lanydrock car park, included a lunch stop at Boconnoc House near Lostwithiel.
Marcus Vincent, who started the event six years ago, said the day went very well.
He said: "We had 36 tractors and all together around 100 people, with some pulled along in trailers behind.
"I would like to thank Mr and Mrs Fortescue for allowing us to stop at Boconnoc House and also Imerys for letting us use their private land.
"It was a big thing to be allowed to drive through and it was really quite something to drive through the tunnel."
The charity has raised money for Help for Heroes for the last four years,
Mr Vincent added: "I think the boys deserve all our support.
"To see all the tractors drive together is an amazing site. We had about two miles of tractors, sometimes stretching out of site in to the skyline."
