Cub Cadet GT 2544 Operator's Manual page 41

Use a 1-1/8" wrench to remove the hex flange nut that
secures the blade to the spindle assembly.
After replacing the blades, apply grease the exposed
threads at the bottom of the spindle bolts to prevent
rust buildup.
When replacing the blades, be sure they are installed
so that the wind wings are pointing upward toward the
top of the deck housing. Tighten the nuts to 90 to 110
ft-lbs. (122 to 149 N·m).
LUBRICATION
After every 10 hours of operation and/or before putting
the deck into winter storage, lubricate the spindle as-
semblies and the spindle belt idler arm with 251H EP
grease or an equivalent No. 2 multipurpose lithium
grease. Excess grease will be expelled from the invert-
ed upper seals of the spindle assemblies. Listen for
the muffled crackling noise of grease being expelled
through the seal to indicate the spindle assembly is ful-
ly greased. Refer to Figure 55.
Every 50 hours, or twice yearly, lubricate the double
pulley with 251H EP grease or an equivalent No. 2
multipurpose lithium grease. Do not over lubricate. See
Figure 55.
