If you haven’t been to a tractor pull, it’s a slow motion drag meet on steroids.
The tractor has to pull a sled which has a moving weight on it. As the weight moves forward it slows the tractor and eventually stops it. It’s a handicap event.
The tractors ain’t your standard farm type, apart from some starting out that way. Think of a tractor with four worked big block Chevys powering it, or at the other end a few VW engines on a little one.
Apart from top fuellers or maybe F1 on, relatively but by themselves ear shattering, an annoying buzz basis, you ain’t gonna hear or feel anything like it.
Here the tractors do their best, then the Leopard gets the sled to end of the run with the weight fully forward and THEN starts to power up, at about 4.55 minutes.
