A trainee skidder operator died from injuries received when the Clark Ranger 666B skidder he was operating rolled down a bank.


He was negotiating a right-hand bend, going downhill, when he drove into a slick of water that had puddled on the inside of the curve. After swerving to avoid the slick, the skidder hit the fence on the opposite side of the road. It then rolled backwards and overturned.

The investigation determined that the Clark Ranger 666B, like most other skidders, steers poorly when coasting downhill on low engine revs and that these factors as well as the operator’s inexperience had led to the fatality.
