1.
Mower Blade Bolts. See Figure 7.
Before operating the mower for the first time, check
the bolts holding the blades. They must be tight. After
the first 8 hours of operation, check them again. When-
ever the blades are removed, it is good practice to install
new lockwashers under the bolts, and again check
tightness after the next 8 hours of operation.
2.
Bent Blades. See Figure 7.
Check for bent blades before mounting the mower and
after impact. Blade tips should be within % inch of the
same horizontal plane. Align all six blade tips, two at a
time as shown in Figure 7 to determine this. Mowing
with bent blades will cause missed strips and a poor
mowing job. Bent blades should be replaced
immediately.

3. Mower Gauge Wheels. See Figure 8.
Remove the gauge wheels after each 10 hours of mow-
ing and lubricate the bushings and axle bolts with
chassis grease. As an alternate to grease, the wheels
can be oiled after each four hours of operation. Make
sure the oil penetrates to the inside of the bushings by
holding the deck at an angle while lubricating.
4.
Mower deck belt replacement. See Figure 8.
The deck belt is automatically tensioned by a spring
loaded idler pulley and does not require adjustment.
Install a new belt in the following manner:
a.
Remove the deck belt guard.
b. Relax the idler pulley tension by pivoting it towards
the front of the deck with a 9/16" box wrench
placed on the hex nut.
c. Remove the old belt.
d.
Place the new belt around the 3 spindle pulleys and
idler.
e. Rotate system by hand to check for free operation
and idler take up.
f. Replace deck belt guard.
