Defendant Robert Latham, aged 64, of Knolton Farm at Overton, near Wrexham, admitted a health and safety charge following the tragedy in July last year.
David Alan Rees, 56, of Ruabon, was clearing the roof of moss when he fell, North East Wales Magistrates’ Court at Mold was told.
Mr Craig Morris, prosecuting for The Health and Safety Executive, said a ladder had been used to go up onto the roof to clear moss from the guttering.
But there was no safe system of work in place and he fell.
It was not known precisely when he fell but he was found on the floor of the cowshed under the sky light.
