Troopers tell the Leader-Times of Kittanning ( http://bit.ly/PzQVdY) that Alfred Adams died at the scene, a farm in Plumcreek Township, about 40 miles northeast of Pittsburgh.
Police say Adams was sharpening the blades of an antique tractor before mowing the grass when the tractor, which was running and in gear, fell down onto him about 11 a.m. Friday.
Police say Adams has propped the deck of the mower up on a bucket when the tractor fell off the bucket and dragged Adams beneath the machine and down a slope about 30 yards.
Cpl. Chris Robbins says Adams was dragged through a fence before the tractor stopped in a ditch.
