PIERZ -- A Pierz man was seriously hurt in a farm accident Thursday morning.

The Morrison County Sheriff's office says 80-year-old Robert Happke was working on the family farm in Buh Township about four miles north of Pierz when the call came in at around 10:15 a.m.

Authorities say Happke was standing on a mixer trailer when the tractor hauling it moved forward causing him to fall off. Happke was then run over by the tractor.

Happke was taken to St. Gabriel's Hospital in Little Falls and later had to be airlifted to St. Cloud Hospital where his condition is unavailable at this time.
