2. Lower the deck to its lowest position. Place the
blade engagement lever in the disengaged
position.

the cable. Do not put tension on the cable. Select
the hole in the lower inside belt guard which aligns
with the end of the cable. Move the end of the
brake cable forward to the next hole in the belt
guard (which will give a small amount of slack in
the cable), and reassemble.

CUniNG BLADE
A. Removal for Sharpening or Replacement
WARNING: Be sure to disconnect and
ground the spark plug wire before work¬
ing on the cutting blade to prevent ac¬
cidental engine starting. Protect hands by
using heavy gloves or a rag to grasp the
cutting blade.
1. R emove the large bolt and lock washer which holds
the blade and adapter to the blade spindle. See
figure 25.
2. R emove the blade and adapter from the spindle.
3. I f the blade or blade adapter needs replacing,
remove the two small bolts, lock washers and nuts
which hold the blade to the adapter. See figure 25.
B. Sharpening
Remove the cutting blade by following the directions
of the preceding section.
When sharpening the blade, follow the original angle
of grind as a guide. It is extremely important that each
cutting edge receives an equal amount of grinding to
prevent an unbalanced blade. An unbalanced blade will
cause excessive vibration when rotating at high speeds,
may cause damage to the mower and could break,
causing personal injury.
The blade can be tested for balance by balancing it on
a round shaft screwdriver. Remove metal from the
heavy side until It balances evenly.
NOTE: It is recommended that the blade always be
removed from the adapter for the best test of balance.
