SANDY, Ore. -- Six people were injured when a berry harvester rolled over on a Sandy farm Monday, deputies said.

A spokeswoman for the Oregon Occupational Safety and Health Administration said the farm where it happened, Sandy Farms, has had other industrial accidents and OSHA violations in recent years.

Crews were initially called to the report of a crash on Highway 211 at Southeast 362nd Drive Monday morning, said Sgt. Nate Thompson of the Clackamas County Sheriff's Office.

"Deputies on scene realized it was not a traffic accident but was a farm machinery accident near that intersection," Thompson said. "A berry harvester was backing up to line up on a row of berries and either a hose or a fitting broke and the harvester lost its hydraulic fluid, which cause the brakes to go out."

He said the harvester rolled backwards and then rolled over onto its top. The six workers who were on the machine were hurt.

Thompson said two of the workers had broken legs and the other four suffered unspecified minor injuries. All were taken to nearby hospitals.

OSHA was notified, but the sheriff's office determined that it was an industrial accident and will not be investigating further.

Oregon OSHA spokeswoman Melanie Mesaros said an October 2013 inspection revealed violations related to a berry harvester on the farm, but she couldn't say whether it was the machine involved in the Monday accident..

She said the farm had also reported an October 2010 accident in which a tractor ran over a worker's leg. And in February 2013, a worker suffered a head fracture in a tractor accident. Both incidents resulted in OSHA citations.
