Replacing conditioner’s tines
(Models: KDD S/ST/SL/SLT (H))
Prior to commencing any operation, on each occasion check condition of bolts, on which
flails are set, as well as condition of flails themselves. When inspecting also take notice of condition
of rubbers where flails are mounted (applicable to shafts with rubber flail mounts). If flails or bolts
or rubbers are worn or damaged, replace them.
Bear in mind, that flails should be replaced in
pairs (opposite) featuring the same weight in order to keep shaft well balanced.
Not keeping
the shaft well balanced may lead to premature wearing of bearings as well as the shaft itself.
In order to remove the flail release the nut with a wrench, remove bolt, and the flail – in case
of mowers equipped with a light-weight conditioner remove the flail rubber pad (
Fig. 39b
).
Installation of a new flail is performed in the reverse order, when tightening the nut apply an
adequate torque (
Tab. 7
).
