A 31-year-old Kea'au man died Friday morning in a single utility tractor crash, according to Big Island police.
The man was identified as Troy K. Pattioay.
At around 11:33 a.m. Friday, Pattioay was operating a 1987 Kenworth Utility tractor pulling an unloaded lowboy trailer and traveling west on Daniel K. Inouye Highway, (New Saddle Road), just prior to the 51-mile marker.
As the truck was traveling down a steep grade it reportedly lost its brakes, crossed to the unimproved west-bound shoulder and lost control, causing the trailer to break free and the utility tractor to roll over, according to police.
Pattioay died at the scene. An autopsy has been ordered to determine the exact cause of death.
His passenger, a 26-year-old Kea'au man, was pinned in the vehicle and had to be extricated by Fire Department personnel. He was taken to North Hawai'i Community Hospital in stable condition and then transferred to The Queen's Medical Center on Oahu.
The highway was closed to all traffic at 11:35 a.m. and reopened at 5:15 p.m.
Police do not believe alcohol or speed were factors in the collision.
Police ask anyone who witnessed the crash to call Officer Larry Flowers Jr. at 326-4646, extension 229.
This is the 25th fatality this year on the Big Island compared with 36 at this time last year.
