5. Sharpening Blades. See Figure 9.
7. Cleaning the mower deck.
With the engine shut off and after the blades have
stopped spinning, check the mower blades periodically
for nicks or dullness. Damaged, dull or improperly
sharpened blades can cause a shattered, rather than,
clean cut and brown areas of grass may develop. Refer
to Figure 9 for the correct sharpening angle.

6. Balancing Blades. See Figure 10.
After a blade is sharpened, check it for balance by
inserting a dowel in the center hole and place between
two level edges as illustrated. A balanced blade will
center itself so the cutting edges are parallel with the
level edges.

CAUTION:
Unbalanced blades are
A
a hazard and will cause premature
wear and failure of bearings and
spindles. If the blades cannot be
balanced by resharpening, replace
them with new ones.
It
With the engine shut off and after the blades have
stopped spinning, check and clean out the inside of
the deck housing periodically. Remove any grass
wrappings between the blade mounting plates and
spindle housings. Grass wrappings, if allowed to accum-
ulate,
may work their way under the bearings and
damage the seals. Excessive grass accumulation in the
deck housing will waste horsepower and cause plugging
and streaking, as well as, corrosion.
8. Tractor and Engine Maintenance. See Figure 11.
Complete tractor and engine maintenance instructions
are outlined in your tractor Operator's Manual. When
mowing,
give particular attention to areas which are
affected by grass accumulation.
Check and brush off the engine air intake screen and
heat exchanger fins daily. Also check and clean the
engine air cleaner element daily. If mowing, under
particularly dry or dusty conditions, a precleaner
which fits over the regular element is available from
your J \e Dealer. This precleaner can be washed
out with soap and water as necessary and will extend
the life of the dry element furnished with the tractor.
