Mechanical winch 45M / MR with a pulling force of 4.5 t features large storage spaces at the front of the winch (PATENT). The MR model has an integrated reduction gearbox, which makes it possible to achieve the same pulling force with less tractor power and, consequently, reduce fuel consumption. The protective grille is foldable, which facilitates transport. Our unique design, featuring a robust construction and a reinforced lower blade, prevents wear and facilitates work.
