Construction or tracked vehicles are those that use a rolling system of metal wheels. These vehicles are designed to operate on difficult terrains and, therefore, require a robust and resistant rolling system. Metal wheels provide the durability and traction necessary to move on uneven surfaces and support the weight and load of the vehicle.

On the other hand, motorcycles and agricultural tractors do not use metal wheels in their rolling system. Motorcycles generally have wheels with rubber tires that fit onto metal rims, but they are not exclusively metal. Agricultural tractors also usually have rubber tires to provide traction on agricultural terrains.

In summary, construction or tracked vehicles are the only ones that use a rolling system of metal wheels, making them suitable for use in demanding work conditions.
