If the timing
belt was installed
correctly
and the timing
arrows were positioned
as shown
in Fig. 7-6, the cutting
blades should
be in the position
shown in Fig. 7-7.

Reinstall the PTO belt onto the RH spindle
drive pulley and
re-install
the deck as described
in "Re-installing
the Cutting
Deck" below.
Reinstalling the Cutting Deck
There are two methods
for reinstalling
the mower deck on the
tractor. One method
involves
rotating
the PTO belt idler bracket
to relieve enough
belt tension
to allow the belt to be placed
in either the PTO pulley or the fixed idler pulley. Because that
method
is difficult,
we recommend
using the second
method
of
rolling the belt onto the PTO pulley.
Install the cutting
deck as follows:
1.
From the right side of the tractor, slide the deck under the
tractor and align the rear deck hanger brackets with the
deck lift arms.
2.
Slide the deck forward
and place the deck front hanger rod
into the slots of the deck front hanger bracket. Then slide
the deck rearward
so that the front hanger rod is at the
front of the slots.

Using the deck lift lever, lower the deck lift arms. From
either side of the tractor,
pull the support
pin in the deck
rear hanger bracket outward,
align the deck lift arm hole
1.
with the deck support
pin and release the pin so that it
goes through
the deck lift arm. Repeat on the other side of
the tractor
to secure the deck.

4.
After first making
sure the deck belt is properly
engaged
in
all of the deck pulleys, route the deck belt forward
through
the center of the front deck hanger rod and toward
the PTO
pulley on the bottom
of the engine.
5.
Using the deck lift handle, raise the deck to the position
that gives you the most horizontal
run of the belt between
the deck pulleys and the PTO pulley on the bottom
of the
engine.
Sitting
in front of the tractor, facing rearward,
make certain
the belt is not twisted;
then reach beneath
the tractor to
grasp the belt and pull it toward
the PTO pulley.
NOTE: References to left and right are from the front of the
tractor in the following
instructions.
Pull the right side of the belt forward
and place the narrow
V side of the belt into the PTO pulley.
While holding
the belt and pulley together,
rotate the
pulley to the left. Continue
holding
and rotating
the pulley
and belt until the belt is fully rolled into the PTO pulley. See
Fig. 7-8.

WARNING!
Use caution
to prevent
pinching
your
fingers
when rolling the belt onto the PTO pulley.
Checkingthe Cutting BladeTiming
During
normal
operation
the timing
of the cutting
blades can
be altered
by abnormal
loads on one, or both, cutting
blades.
Regularly
check the timing arrows on the spindle
assemblies
to
make certain they are 90 ° from each other.
If the timing
arrows are not 90 ° from each other, proceed
as
follows:
Remove the deck from the tractor.
Remove the idler
bracket
backstop.
Refer to Figure 7-5.
Pivot the idler bracket/idler
pulley to relieve the tension
on the timing
belt, and reposition
the drive pulley and/or
timing
pulley to achieve the 90 ° orientation
of the timing
arrows.
3.
Re-install
the idler bracket
backstop
and position
so that
there is a 1/8"gap between
the backstop
and idler bracket.
Tighten
the hex screw and flange
lock nut to secure in the
adjusted
position.
