(KMZA)--A motorcyclist was killed Tuesday afternoon in a two-vehicle crash in Washington County.

The Kansas Highway Patrol says 68-year-old Thomas Lewis, of Firestone, Colorado, was eastbound on U.S. 36 Highway, east of Osage Road, when his motorcycle struck the rear of a John Deere tractor around 2:45.

Lewis was ejected from his motorcycle and pronounced dead at the scene.

It's unknown at this time whether Lewis was wearing a helmet.

The driver of the tractor, 26-year-old Jonathan Schmidt, of Diller, Nebraska, was not hurt.
