A 63-year-old man from Shafer, Minn., died in a snowmobile accident on Saturday, according to the Chisago County Sheriff's Office.

Dennis Holt was killed as he moved a snowmobile on private property about 11:20 a.m. near Shafer, in Franconia Township. The snowmobile accelerated rapidly, striking a car-hauling trailer parked nearby, the Sheriff's Office said.

Holt was not familiar with the snowmobile, which was different from most because a lefthanded throttle had been installed. That appears to have contributed to the accident, the Sheriff's Office said.

A witness tried to revive Holt, but he died at the scene.

Alcohol or drugs were not involved, according to a news release.

The Sheriff's Office is investigating.
