The Evolution Self Loader provides all forestry transport services, being adaptable to any make of tractor with a minimum of 160HP (depending on the terrain type). Another aspect that differentiates that Evolution Self Loader from other models is that this self loader does not use a system of stabilizers to secure the equipment, as well as being capable of accommodating different lengths of timber. It also has various command options using hydraulic and electric joysticks.
