Gruber SM Pack v1.0.0.0

The Gruber manure spreaders SM 350T and SM 450T are specially designed and built for mountain areas. The designation "T" stands for subscript,
this means the frame that was set lower and the wheels that were placed on the outside. The axle was set far back,
in order to still guarantee the support load on the tractor rear axle when the manure spreader becomes increasingly empty.
