The Ploughing Trade Exhibition will not go ahead this year.
The event normally draws a crowd of about 300,000 people and was due to take place in Ratheniska, Co Laois, in September.
But the organisers say it's been cancelled because of uncertainty about what Covid restrictions will be in place at that point.
However, the national ploughing competitions will still go ahead.
Organisers say it's a 'massive disappointment' to call off the event for the second year in a row.
