REV B 6-6 125816
When mounting blades, rotate them after installation to
make sure blade tips do not touch each other or sides of the
mower.
Belts
Inspect belts frequently for wear and serviceability.
Replace a belt that shows signs of severe cuts, tears,
separation, weather checking and cracking, or burns caused
by slipping. Slight raveling of belt covering does not indicate
failure; trim ravelings with a sharp knife.
Inspect the belt pulley grooves and flanges for wear. A new
belt, or one in good condition, should never run against the
bottom of the groove. Replace the pulley when this is the
case, otherwise, the belt will lose power and slip excessively.
Never pry a belt to get it on a pulley as this will cut or
damage the fibers of the belt covering.
Keep oil and grease away from belts, and never use belt
dressings. Any of these will destroy the belt composition in a
very short time.
Center Deck Belts Adjustment
The deck belt tension remains constant by means of a
tension idler and spring. The spring tension should be such
that the belt does not slip under normal operating load
conditions, assuming the belt is not excessively worn or
damaged. As the belt stretches and wears in, adjustment
may become necessary. To increase belt tension, move the
spring chain one (or more) link(s) at the anchor point on the
deck frame. Figure 6-14, Figure 6-15 & Figure 6-16
IMPORTANT: Do not over tension the spring to
compensate for a badly worn belt or pulley.
Side Deck Belt Adjustment
The side deck belt tension is adjusted by changing the
compressed length of the idler spring.
1. Loosen the jam nut. Figure 6-16
2. Rotate the adjustment nut the proper the direction
until the idler spring is compressed to the dimension
shown. Figure 6-16
3. Tighten the jam nut against the adjustment nut.
