There are three matched flailing stations. Starting from the feed tray, the
first is 3 link, the next two 4 link . The first is positioned about 4" from the
face of the beater drum and the last 4" from beater drum inlet. the center
station is centered between the first and last . Each station is oriented
@120° from the others.
One or both of the center stations may not be required depending on the
mulch. With very dry and old material these can be removed.
BEATER SHAFT:
If a foreign object such as a boulder or log enters the beater chamber it
may bend the shaft. The only way to check this is to remove the shaft and
have a machinist check for straightness. If the total run out should exceed
.015", replace the shaft.
BLOWER WHEEL:
The blower fan is keyed to the driven shaft with four square head set
screws. Inspect these screws for tightness periodically and after the first
twenty hours of use. If the fan becomes loose, reposition if necessary,
then re-tighten screws. Screws can be accessed through blower outlet
after discharge chute has been removed.
Wear of the wheel is evident when the leading edges of the blades begin
to curl back. If a heavy object hits the paddles, bending and unbalance can
occur. In either case, replace the wheel.
DO NOT ATTEMPT TO REPAIR THE BLADES.
DO NOT OPERATE THE MACHINE WITH A WORN WHEEL.
A WORN OR UNBALANCED BLOWER WHEEL IS DANGEROUS AND MAY
CAUSE DEATH OR SERIOUS INJURY!
DRIVE COUPLING: The drive coupling transmits power to the blower and beater shaft.
Excessive misalignment of the shafts (axial or angular) will produce
vibration. If so, realign coupling as necessary. Check the set screws and
connecting bolts every 100 operating hours for loosening or other
abnormality.
If the coupling becomes misaligned, contact your servicing dealer.
Otherwise, follow this procedure: Determine the direction and degree of
misalignment by measuring with a caliper or divider around the periphery
of the drive coupling flanges. If the gap is measured on the top of the
driven coupling flange, this indicates that the shaft(s) have shifted
downwards. If a gap is measured in the side of the driven flange this
indicates that either the blower housing assembly has shifted to one side
or the driven shaft has shifted at the end opposite the engine.
