I still have it in the back of one of the barns - I don't (and wouldn't) use it today, but it's great to show people and see the look on their face when I tell them what it does. We were always a little impatient - the idea was to let the truck idle and let the screw work its way through the log. Dad had me sit in the truck and goose the throttle a little to make the thing split faster. Picked the truck up one day and almost set it off the jack stand when we hit an extra tough log. Ahhhh, those were the days...
