When reinstalling the blades, be sure
they are installed so that the wind
wings are pointing upward toward the
top of the deck. Tighten the nuts to 90
to 110 ft-lbs. (122 to 149 N·m).
After replacing the blades, apply
grease to the exposed threads at the
bottom of the spindle bolts to prevent
rust buildup.
B. Lubrication
After every 10 hours of operation and/
or before putting the deck into winter
storage, lubricate the spindle
assemblies and the spindle belt idler
arm using 251H EP grease or an
equivalent No. 2 multipurpose lithium
grease. The lube fitting for the outer
spindles can be accessed by removing
the button plugs in the belt covers.
Use grease liberally. Excess grease
will be expelled from the upper spindle
seals. When the spindle is fully
greased, the expelled grease will
cause the top spindle seal to give off a
muffled crackling noise (Refer to
Figure 49).
Apply grease to all other lube fittings
after every 50 hours of operation.
Refer to the MAINTENANCE CHART
and LUBRICATION ILLUSTRATION
