Westvaco used Morbark chippers at all their woodyards. The old ones had 12V71 Detroits and the knuckle booms with 50 or 60 levers on them, their newer ones had 600hp Cummins engines on them. They would both sit there and run wfo all day long every day, only stopping to change knives once in a while. I moved this one from Dillwyn, Va. to Parkersburg, W.V. with this F model Mack, around 1980. That picture was in my oldest photo album, here's a few more from my chip hauling days- "Corn Stalk"s V8 Mack on the dump. The dump is only about half way up, it was dang near straight up when it got to the top. Sitting on top of the mountain on rt. 60, east of Buena Vista, Va. I walked up on the bridge where the Blue Ridge Parkway goes over rt. 60 to take this picture. Sitting at my uncle's house. Sitting at the bottom of the mountain on rt. 130. I had walked down to the James River. I didn't always sit around, sometimes I actually hauled chips. Chip pile at Westvaco in Covington, Va. I used to have a hammock...and long hair.
