Meiren's hydraulic 4-block auxiliary blade distributes the pressure between the front blade and the auxiliary blade. Each block has its own cylinder, which ensures equal working pressure along the entire length of the additional blade. In the case of hard snow, the entire weight of the plow is transferred to the first blade, and in the case of a snow thrower, to the additional blade equipped with a completely rubber blade. The use of the right pressure in the additional blade system guarantees an extremely clean road surface and economical use of the blades. A 6-piece hydraulic trowel is also available for the MSPN3404, MSPN3704 and MSPN4004. The Easy Fix system of additional blade rubber blades saves time when opening and reattaching the bolts and the blade can be set to the desired height.
