A machine for spreading materials on the floor is disclosed. The machine has a structural assembly arranged on three independent roller assemblies (2, 3, 4), at least one of which can be oriented to steer the machine. At the front part of the structural assembly a levelling head (10) is provided with an element (21) for distributing and levelling the application materials. The roller assemblies (2, 3, 4) on which the machine is supported are coupled to a hydraulic drive actuation system. The hydraulic fluid to each of the roller assembly can be individually and selectively cutting off to change the drive actuation force and speed conditions of the machine. The levelling head (10) is arranged in the assembly by means of a support (15) which allows the movement of the head. Shock absorbers (14) prevent the machine vibrations from being transmitted to the elements of the head (10). The roller assemblies (2, 3, 4) individually incorporate a clutch lock, linked to the drive actuation system, allowing selective coupling and uncoupling any of the groups (2, 3, 4) with respect to the drive transmission.
