More vigilance has been urged in rural communities as farmers enter a high-pressure period.
Agriculture Minister Simon Coveney said it was the peak time of year for machinery use on farms.
"Summer is an incredibly busy, and high-pressure time on Irish farms," he said, as he launched a new book aimed at making children safety aware.
"The weather this May was particularly bad, and so our farmers have been playing catch-up since with silage," he said.
Farming remains the most dangerous occupation in Ireland, with 25 adults and five children losing their lives on farms last year.
Seven people have lost their lives so far this year in farm accidents.
Tractors and machinery are responsible for almost half of all deaths.
Mr Coveney said the figure showed that great vigilance was required with the high number of tractors and machines out in fields and in the country's roads.
Alma Jordan, who lives on a farm in Julianstown, Co Meath, with her husband Mark Delaney and their son Eamon (3), founded AgriKids.ie website after the high level of farm deaths.
She has penned a book for young children, 'Tales from Riverside Farm', which has a central theme of farm safety running through it.
Ms Jordan said the key phrase that emerged from the statistics was that 'farmyards are not playgrounds'.
