A heavy-duty gearbox transfers power to the power-band drive belts through cross shafts with intermediate bearing supports:
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.

An easy-end transport system is available as an attachment on the 520 Flail Shredder for more convenient transport positioning.
The attachment includes two additional arms, one for the front and one for the rear of the machine:
Transport arms are pinned in the down position for transport and pinned up during field operation.
Deflectors can be used on the front of the shredder to prevent cut material from being thrown forward. Rubber deflectors are recommended when shredding in rocky areas.
Additional gauge wheels can be ordered, if needed, for improved cutting performance.
Transport warning lights are standard on the 520 Integral Flail Shredder and optional on the 520 Drawn Flail Shredder.
The center divider minimizes the center strip of uncut material when clipping grass, idle acres, or non-row-crop crops.
This bundle is for use on all shredders with the following serial numbers:
NOTE: Previous machines did not have center-cut knives. To install, order them from Parts.
