The victim, named locally as Damien Forde, 25, from the Glanworth area, was killed when the tractor he was driving struck a ditch as it travelled from Glanworth to String Crossjust after midnight.
The tractor crashed through the ditch and came to rest in a field. Mr Forde was pronounced dead at the scene. The alarm was raised, the site was preserved, and Mr Forde’s body remained at the scene until later in the morning to allow for a forensic investigation by Garda road traffic collision investigators.
The Health and Safety Authority has also launched a separate investigation into the circumstances surrounding the accident.
It is understood that some of Mr Forde’s close family are abroad and are making arrangements to travel home.
Gardaí, who have appointed a family liaison officer to help Mr Forde’s family, have asked anyone who may have witnessed the accident, to contact Fermoy Garda Station on 025 82100 or the Garda Confidential Line on 1800 666 111.
Mr Forde’s death is the second farm-related fatality in Cork, and the third farm-related accident since mid-May.
A toddler from near Schull, in West Cork, died after he was accidentally struck by a heavy steel gate on the family farm.
And a 70-year-old farmer from the Carrigadrohid area near Macroom was left in a serious condition after an incident on the family farm late last month.
The man and his son were putting a bull into a pen when the animal struck out, and kicked a heavy gate at the farmer.
The farmer suffered serious internal injuries and after emergency treatment at the scene, he was airlifted to Cork University Hospital.
Farming leaders and representative bodies have again urged the farming community to exercise extreme care, especially over the coming months during the silage season, and motorists are advised to take extra care on the roads due to the high volume of farm vehicles.
