To overcome this, ballast tractors tend to have high-powered, low geared engines that provide substantial torque, especially at low speeds. ![]() High inertia is encountered when starting to move a heavy load. Since the load is separate from a ballast tractor, it provides no ballast: the drawbar only transmits a horizontal force. With a semi-trailer, ballast is added in the form of the weight of the attached trailer pressing down upon the tractor's fifth wheel. Without it, there would be unproductive wheelspin. The additional weight increases the friction between the tyres and the road surface, allowing the tractor to overcome the inertia and friction of moving a heavy trailed load. For a ballast tractor, ballast is added over the driving wheels to maximize traction. The ballast tractor's name derives from the nautical term “ sailing ballast” describing heavy material added to a vessel to improve stability. Titan Spezialfahrzeugbau GmbH Ballast tractors with Mercedes-Benz Actros cab. Increasingly, remote-controlled, self-propelled modular transporters (SPMT) are being employed in traditional ballast tractor/trailer roles. Ballast tractors can be traced back to the 1940s when heavy haulers from the UK started employing purpose-built Scammell Showtracs a short wheelbase 4x2 ballast tractor. These units are classified as N3 Category of Large goods vehicle. Extra-heavy-duty chassis versions of mass-production tractor units are fitted with drawbar hitches and a separate ballast box as an alternative. Only a handful of manufacturers produce dedicated ballast tractors. Typical ballast tractor loads include oil rig modules, bridge sections, buildings, ship sections, and industrial machinery such as generators and turbines. Typical drivetrains are 6×4 and 6×6 but also available in 8×6 and 8×8. When feasible, lowboy-style semi-trailers are used to minimize a load's center of gravity. It is designed to utilize a drawbar to pull or push heavy or exceptionally large trailer loads which are loaded in a hydraulic modular trailer. Eliminated the need for a trailer or using the bucket for my chainsaw, shovel, weed wacker, etc.A ballast tractor is a specially weighted tractor unit of a heavy hauler combination. ![]() It is a phenomenal attachment for my tractor. I bought my Ultimate Rack several years ago. Helps me complete yard work so much faster. So convenient to keep all my tools loaded on it and just roll it into the corner of the garage until i need it again. KD Bought my Ultimate Rack over 5 years ago! I use it on my JD X728. If you own a compact tractor, you need to have the Ultimate Rack! I use it as a power lift gate as well to easily unload heavy item like appliances from my pick up truck to the entrance of the house. The Ultimate Rack provides that function obviously, but it is great for storing all my yard tools, including shovels, rakes, lifting chains, bar oil for my chainsaw and string trimmer. I came across this product while looking to puchase a rear ballast box to add weight on the rear of the tractor when using the fron end loader. ![]()
