(PD) - A Fairfield man died Tuesday morning after being crushed by a tractor implement he was cleaning in a Sonoma Valley vineyard, authorities said.

Franklin Palacios Carrillo, 34, was found by another vineyard worker about 7:30 a.m. pinned beneath his tractor’s tiller attachment, the Sonoma County Sheriff’s Office said.

Carrillo was working in a vineyard managed by Walsh Vineyards Management and was apparently trying to remove a tangle of vineyard wire from his tractor’s tilling tines when the implement dropped and crushed him, according to Cal-OSHA, which is investigating.

The property where Carrillo was found, Arrowhead Vineyard, off Napa Road east of Nicholas Road, has been owned by Gundlach Bundschu Winery, though ownership could not be confirmed Tuesday.
