A Norfolk field became the focal point for the UK's farm machine industry as thousands of farmers gathered to watch the latest technology put through its paces.
Millions of pounds worth of equipment was on show as the Norfolk Farm Machinery Club (Normac) held its biennial Cultivations Event at Silfield Farm near Wymondham.
The 80-hectare site featured more than 100 machines from some of the world's biggest manufacturers, carrying out working demonstrations of tractors, cultivation equipment, seed drills, crop sprayers - and an autonomous farm robot.
It attracted dealers and farmers from across the region, and further afield from all corners of the country.
Normac county organiser Jonathan Tunmore said this working demonstration day was driven by the same key principles that launched the event in 1946, during the post-war growth in farm mechanisation.
"The whole event was set up for farmers and farm workers to better understand what was in the market place and how to use it," he said. "Seventy years on, the concept of the demonstration day has not changed.
"Farmers in between harvest and [seed] drilling can come and have a look at something on a real farm, in a real working scenario and decide if that piece of kit is for them."
The event was hosted by landowner James Alston, whose late father Alan Alston was a significant supporter of Normac and had previously hosted demonstrations and training events for the club.
"That was a big part of why it was a very easy decision to say yes to this, because my father was very keen on Normac, and very keen on machinery generally, so it is lovely to be able to host this event," said Mr Alston.
He added that the site was on heavier land than previous Normac events and, after a wet summer, "it is good for everyone to see machines working in slightly more challenging conditions than they may otherwise have been."
Among the exhibitors was Norwich-based John Deere dealer Ben Burgess, whose managing director Ben Turner said: "It is a great opportunity for us as a company to show all our machinery and have our engineers and experts here at the same time to answer questions from our farming customers.
"There will be very few deals done today - but we are planting seeds, that is the way we look at it."
Another exhibitor was Thomas Sands of Sands Agricultural Machinery, which builds about 50 of its crop-spraying machines per year at its factory near Stalham.
He said the event was a valuable opportunity for potential customers to see the firm's new Infinity sprayers at work in a field setting.
"It is a massive benefit to give everyone the overall view of the machine," he said.
"It's good to get 'hands on' and we also know if we leave here and a customer wants to see a demo that we must be the pick of the bunch that they want to see."
