A 57-year-old Malahide Township man is in critical condition after being run over by a farm packer being pulled by a tractor.

He was airlifted to hospital.

Elgin OPP say the accident happened around noon Friday on a rural property on Eden Line between Plank Road and Sandytown Road in the Township of Bayham.

The male was cutting the lawn around a cabin situated on the property. He was in the process of walking backwards with the push mower as a farm tractor passed behind him. 

Police say the man observed the farm tractor but did not realize that it was towing a cultivator and behind that the packer.

Thinking it was clear, he stepped backwards into the path of the packer and was run over.

The Ministry of Labour is not investigating.
