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 54.
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.
Refer to Figure 54.
