The rotor bearings are now made of steel and have a three-lip seal to keep the dirt out and increase the life of the bearings.

 

The side and center bearings now have guards in order to avoid leaks and dust, increasing the life of the bearings.

Front rubber deflectors keep debris and other materials under the shredder and away from the tractor and operator. Because they are made out of rubber, they will not dent or rust.
