If the timing
belt was installed correctly
and the timing
arrows were positioned
as shown in Figure 7-5, the cut-
ting blades should be in the position
shown in Figure
7-6.

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:
•
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.
•
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 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.
•
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.
•
Using the deck lift handle, raise the deck to the posi-
tion 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.
SECTION 7--
SERVICE
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 nar-
row 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 Figure 7-7.

ARNING: Use caution to prevent pinching
your fingers when rolling the belt onto the PTO
pulley.
Checking the CuttingBladeTiming
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 7-4.
•
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.
•
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.
