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.
The flail fastening system eliminates clogging from mud or crop residue. Its bracket design also helps prevent knife and ring loss.
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:
Kevlar is a U.S.-registered trademark of E.I. du Pont de Nemours and Company.
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 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.
Hard-to-reach center bearings can be serviced with the conveniently located grease fittings at the rear of the machine:
