A man in his 70's has died in an accident on a farm near Ouyen on Monday night,

Police, ambulance and Worksafe officers attended the farm accident in which the man was apparently run over by a trailer being towed by a utility at his Patchewollock farm.

 It is understood the prperty owner John Hulland, 76,  was standing alongside the moving trailer, feeding hay to sheep when he was knocked to the ground about 9.30pm Monday.

It is believed to be a new piece of tuck/tray feeding combination recently purchased for use on the property.

 WorkSafe is investigating.

 The fatality brings the number of confirmed workplace deaths this year to 10, and is the sixth to occur on a farm.

 WorkSafe Acting Executive Director Health and Safety Paul Fowler urged farmers to put safety first.

 "Tragically, many on-farm fatalities involve people doing tasks they have done many times before, but experience doesn't prevent injuries or deaths," he said.
