Andrew John Wills, of Speldhurst, Simon Francis Fitch, of Tonbridge, and Robin Turney, of Henley-in-Arden, were due to appear at Maidstone Crown Court on 1 April.
The case has now been delayed to allow more time for a report to be prepared and will be heard in Canterbury Crown Court in early September.
The three men, who remain on unconditional bail, are facing fraud charges brought by the Department for Environment, Food & Rural Affairs (DEFRA).
At an earlier hearing at Maidstone Magistrates’ Court, Mr William Dean, for DEFRA, said the case related to applications to the Rural Payments Agency for more than £2m of Rural Development Grant money.
Simon Fitch pleaded guilty to one charge and not guilty to another, Robin Turney pleaded not guilty to two counts and Andrew Wills pleaded not guilty to one charge. All the charges relate to making or supplying articles for use in fraud.
