Lubrication
The biade spindles on the cutting deck are per­
manently lubricated.
Cutting Biade
The blades may be removed for sharpening or
replacement as follows:
1. Remove the large bolt and lock washer
holding the blade and adapter to the blade
spindle.
2. Remove the blade and adapter from the
crankshaft.
3. Remove the two smaller bolts, lock washers
and nuts holding the blade to the adapter.
(See figure 32.)
When sharpening the blade, follow the original
angle of grind as a guide. It is extremely important
that each cutting edge be ground equally to pre­
vent an unbalanced blade. An unblalanced blade
will cause excessive vibration when rotating at
high speeds and may cause damage to the mower.
The blade can be tested for balance by balancing
it on a screwdriver. Remove metal from the heavy
side until it balances evenly. (See figure 33.)
NOTE
When replacing the blade, be sure
the side of the blade marked “Bot­
tom” or having the part number, is
facing down toward the ground
when the mower is in the operating
position.
