2. Lower the unit to the ground, place all controls in
neutral, shut off engine, set park brake, remove
key, and wait for all moving parts to stop before
dismounting.
NOTE: For 3-point hitch units, unhook to gain access

SERVICING ROTORS (FLAIL TUBES)
Do not handle knives with bare hands. Careless
or improper handling may result in serious injury.
■ Any excessive vibration caused by worn or
missing knives or damaged drive components can
cause damage to the shredder and personal injury.
Excessive vibration can also be transmitted
through the hitch mounts and PTO to the tractor
resulting in tractor damage.
■ Once field operation has been started, it is the
responsibility of the owner/operator to monitor and
maintain acceptable rotor balance. Refer to Bal-
ance Statement, page 5, for details.
NOTICE
■ Read Balance Statement, page 5, before replac-
ing any knives.
Refer to Replacing Flails, page 29, for knife or knife
component replacement.
The Woods Center Drive Flail Shredder has been
designed for durability when shredding any type of
crop. Some operating conditions will shorten the life of
the shredder or components. These include operating
too low to the ground or in frequent contact with the
ground, and contact with large rocks or other foreign
objects. Over time, some types of soils and crops can
cause wear or damage to rotor components and affect
rotor balance, leading to increased vibration. Contin-
ued operation with excessive vibration can damage the
shredder, requiring rotor service, removal, or replace-
ment.
Factory balanced spare replacement rotors are avail-
able through your local Woods dealer. Contact Woods
