Features
Drawn or integral model available to meet a variety of applications
Square rotor designed for superior rotor strength
Designed for superior rotor strength, the square rotor, together with the opposite-mounted flails, provides a machine with less potential vibration, increasing the life of rotor bearings and belts.
Since 248 knives are mounted on the full length of the rotors on the main cutterbar, with 2.5 cm (1 in.) of overlap, a stalk won't get missed. This is a significant improvement over the 216 knives mounted on the previous 220 Flail Shredder.
Rubber deflectors will not dent or rust
Flail fastening system eliminates clogging from mud or crop residue
The flail fastening system eliminates clogging from mud or crop residue. Its bracket design also helps prevent knife and ring loss.
Heavy-duty John Deere-designed gearbox
A heavy-duty, John Deere-designed and John Deere-built gearbox transfers power to the Kevlar® drive belts through cross shafts with intermediate bearing supports:
- The transmission is bolted directly to the frame.
- This gearbox has a constant-duty rating of 180 hp and a maximum rating of 270 hp.
- It carries a limited two-year warranty.
Kevlar is a U.S.-registered trademark of E.I. du Pont de Nemours and Company.
Steel rotor bearings for increased bearing life
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.
Optional wheel supports eliminate uncut middle strip in non-row-crop field
Optional wheel supports eliminate the uncut middle strip in crops like wheat, oats, and barley. The shredder can be pulled at an angle, offsetting the rotors and cutting evenly across the entire width of the machine.
Serviceability
Hard-to-reach center bearings can be serviced with the conveniently located grease fittings at the rear of the machine:
- There is no need for the operator to crawl under the machine to perform this service task, thus increasing the probability of the job being performed and completed safely.

Accessories and Attachments
Easy End Transport
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:
- Reduces the time it takes to prepare the machine for endwise transport
- Allows the arms to be left on for normal field operation
- Not compatible with the disk hitch attachment
- Transport width of less than 8 ft
Transport arms are pinned in the down position for transport and pinned up during field operation.
Miscellaneous
Deflectors - Rubber - BP18050
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.
