11. If the fixed idler contacts the end of the
adjustment slot and more belt tension is
required, a small change in the lengthen the push
arms can be made (Fig. 53).
12. To adjust push arms, loosen jam nut and rotate
ball joint counterclockwise, one turn at a time.
Adjust each side the same amount (Fig. 53).
Note:
Increase belt tension by lengthening
the push arms and decrease belt tension
by shortening push arms.
IMPORTANT: If the push arm lengths are
changed, then the mower deck must be
releveled. See Mower Leveling on page 55.

Replacing the Grass Deflector
POTENTIAL HAZARD
•
An uncovered discharge opening will allow
objects to be thrown in operator’s or
bystander’s direction. Also, contact with
blade could occur.
WHAT CAN HAPPEN
•
Thrown objects or blade contact can cause
serious injury or kill you or bystanders.
HOW TO AVOID THE HAZARD
•
Never operate mower unless grass deflector
or catcher are installed.
1.
Remove the locknuts, bolts and springs holding
the deflector mounts to the pivot brackets
(Fig. 54).
2.
If the pivot brackets need to be replaced, remove
the carriage bolts and cone locknuts holding the
old brackets to the top of the discharge opening,
then install the replacement pivot brackets. Make
sure the carriage bolt heads are on the inside of
the cutting unit (Fig. 54).
3.
Install the deflector mounts onto the pivot
brackets with the bolts, springs and locknuts.
Make sure the straight ends of the springs are
positioned between the deflector mounts and the
grass deflector (Fig. 54).
4.
Tighten the locknuts until they contact the pivot
brackets (Fig. 54).
IMPORTANT: The grass deflector must be
spring-loaded in the down position. Lift the
deflector up to test that it snaps to the full
down position.
