Dozens of tractors took to the roads of Huddersfield.
They made for a noisy and colourful sight around Upper Denby as they set off on a big charity mission.
The tractor drivers are bound for Whitby, on the North Yorkshire coast, and aim to get there and back over four days - a daunting task for some of the vehicles which are over 50 years old.
The Vintage Tractors Charity Run is in aid of the Royal National Lifeboat Institution and the Yorkshire Air Ambulance.
Tractor-owners from across the region gathered at Denroyd Farm in Upper Denby for the start of the run which is bound for Whitby Lifeboat Station.
The tractor drivers aim to get their vehicles to Whitby by Monday teatime, after stops in Wakefield, Garforth, Tadcaster, Easingwold, Hutton le Hole and Grosmont.
