Our most recent Innovation to the Legendary Towline is the Surface Mounted “Gorilla” Drive! Say goodbye to monumental concrete pits, as this drive requires little to NO concrete work! This drive can be supplied for In-floor or On-floor Applications. This drive is virtually maintenance free, as it has very few moving parts. When this drive system is coupled with a Side-Pull Tow Cart, absolutely NO Concrete work will be needed! This drive is equipped standard with a Spring Operated Take-Up system and an Automatic Chain Oiler.
