11.7 Flails
The position and condition of the rotation flails is crucial to the quality of the defoliator job done by
the machine. The flails must be positioned exactly over the rows to optimally clean the foliage and
tailing from the beets. All flails must be in good condition. Any missing flails could affect the balance
of the rotor and lead to severe vibration.
11.7.1 Steel Flails:
Row spacing: Steel flails row spacing is not adjustable. If row spacing must be changed a genuine pre
- balanced replacement drum(s) is available for your Amity defoliator. Please see your parts manual
for the appropriate part number(s).
Flail replacement:
1. Open defoliator top doors for access to flails
2. Inspect all flail and determine which ones
need to be replaced.
3. Cup – Remove flail rod bolt, L - Knife – Remove
mounting bolt
4. Remove flail tube with flails and spacers.
5. Inspect and replace missing or damaged components using only genuine Amity parts. Refer to
the parts manual for the appropriate part numbers.
6. Reinstall flail rod/bolt through flail tube with flails and spacers preassembled.
7. Tighten flail rod/bolt.
8. Close doors and run machine up to operating speed to check drum balance. If unbalanced, en-
sure flails opposite of replaced components are also new. If still unbalanced, tubes may need to
be removed and rebalanced.
NOTE: When individual steel flails are replaced the flails on the opposite side should also be re-
placed to maintain the drum balance.
NOTE: Steel drums on defoliators rotate at approximately 1000 RPMs; if all new flails are installed
on the drum it should be balanced to prevent excess vibration.
